Senso Bluetooth Headphones Review (2019): Which Ones Are The Best?

Senso Headphone ReviewsAlthough it could be categorized as a first-world problem, a tangled earphone cord is one of the most annoying things ever. People have been dealing with headphone cords ever since the 1910s, when U.S. Navy officers were the only ones using headphones. True wireless headphones weren’t invented until the ’60s. And today, they’re the most popular they’ve ever been.

Commercial Bluetooth earphones are getting better every day. Companies have found a way to make them tiny and completely cordless, and have also made their battery life much longer than it was before.

Now we can fully enjoy the experience of listening to music without having to untangle cords, and all that at an affordable price. And one of the most popular Bluetooth headphones manufacturers today is Senso.

Stick around for my Senso Bluetooth headphones review, as I’ll present 4 different headphone sets, and tell you all about their pros and cons. In the end, I’ll reveal which one is the best, and which one I definitely recommend to our readers.

4 of the best senso bluetooth headphones today

Types of wireless headphones

Senso HeadphonesThere are many types of wireless headphones you can buy today. Back in the 2000s, the only ones you could buy were the mono Bluetooth earphones. Or should I say — earphone? In any case, their sole purpose was making phone calls — that’s pretty much all they did. Although they were new and impressive at the time, Bluetooth mono headphones had many issues, especially when it comes to connectivity.

In the 2010s, us music lovers finally got double Bluetooth headphones. However, they were far too expensive when they first came out. They also had plenty of problems. Even the priciest Bluetooth headphones were dysfunctional at times.

Luckily, we’ve recently seen major improvements in this field of technology. Now we can truly enjoy the wireless experience without any cuts or disconnections. Nowadays, you can buy big on-ear wireless headphone sets that are completely cordless, and their sound quality is amazing. But these are insanely expensive, as you might have guessed.

But don’t worry; there are more affordable models, as well. They come in various shapes and sizes — from big and bulky to small and unnoticeable. Their pricing also varies, and there’s something for everyone’s budget. It all boils down to you and your personal preferences.

The most recent advancement in Bluetooth technology are the truly wireless headphones. ‘Truly wireless’ implies that there are no cords whatsoever involved, not even the one connecting the two earphone pieces. I suppose we’ll be seeing a lot more of this technology in the future.

Advantages of Bluetooth headphones

The first and most obvious advantage of wireless headphones is the lack of cords. They are not only annoying and prone to tangling but also restrict your mobility. For runners and gym-goers, that’s a nightmare come true.

Wireless earphones give you all the freedom you never knew you needed. It might seem like you have no problem with wired headphones right now, but you’ll realize how limiting they were once you try wireless headphones. With wireless headphones, you can run and exercise freely while listening to your favorite tunes.

New technological advancements in this field are made every single day. Until recently, we weren’t even able to imagine totally waterproof earphones. Bluetooth technology does not work well underwater, or so we thought. But nowadays, we can actually buy waterproof headphones, and they’re not even that expensive either. Isn’t it amazing that we can finally listen to music while swimming?

Disadvantages of Bluetooth headphones

Although they are impressive, Bluetooth headphones are not perfect. There are several disadvantages that you should know about.

First of all, Bluetooth headphones are pricey. They’re not completely unaffordable, but they are much more expensive than the wired earbuds we’re used to. Why is that?

Well, for starters, the technology is rather new. Remember the 90s, when first commercial computers came to be? Not everyone could afford them, and they were rare. The case is the same with Bluetooth headphones. But, much like PCs, their cost will most likely go down in a few years.

Another reason why they’re so costly is that they have a lot more components than their simpler wired counterparts. For example, wireless headphones use batteries, Bluetooth modules, etc. And when you add all that up, you end up with a hefty price.

The next downside I’d like to warn you about are the connection issues. Even though Bluetooth technology has been around for a while, it has not been perfected yet. However, connection issues only occur under certain circumstances. If you use your Bluetooth headphones properly, you most likely won’t experience any problems.

And finally, we might have to deal with subpar sound quality. Of course, that doesn’t apply to all Bluetooth headphone models, but it is a common issue. But again, I bet we’ll soon see an improvement in this field, as well.

A quick buying guide

Whether you’ll actually benefit from having Bluetooth headphones depends a lot on you. If you’re an active person and you like to exercise, play sports, swim, etc., then you’ll definitely find them useful. Even if you’re not that active, you can still enjoy these headphones, obviously.

I’ve just talked about the different types of Bluetooth headphones. It’s important to choose the right model for yourself, so here’s my advice regarding that.

People who use their PC often, such as gamers and programmers, will benefit the most from full Bluetooth on-ear headsets. They’re super comfortable, and their sound quality is amazing. However, be prepared to set aside a lot of money.

On the other hand, people with active lifestyles who like to exercise and run will definitely enjoy small Bluetooth earbuds the most, especially if they’re truly wireless. After all, some companies specialize in sports headphones — Senso is one of them. Their ActivBuds series was specifically designed for athletes and overall active use.

Senso Bluetooth Headphones Review

In the next part, I’ll give my honest review of 4 different Senso ActivBuds Bluetooth headphones.

1.  Senso ActivBuds S-250

Sometimes you’re on a tight budget, and you just need a low-cost, but decent headphone set that will simply do the job of playing music. And that’s exactly what Senso ActivBuds S-250 will do. Their sound quality isn’t great, but it’s definitely worth the price. It’s one of the cheapest Bluetooth headphones on the market right now. In the rest of this Senso Bluetooth headphones review, I’ll share my honest thoughts about S-250.

Senso ActivBuds S-250 are one of Senso’s top-sellers, especially among athletes. They’re definitely the simplest of the bunch, but that’s actually why they’re so popular in the fitness world. Compared to their more expensive counterparts, the S-255 ActivBuds, they’re not that much worse, but they are much cheaper. They’re definitely the best option for people on a budget who don’t really care about sound quality.

According to Senso’s website, Senso ActivBuds S-250 offer a true HD high-fidelity sound, noise cancellation, a comfortable fit, and 9+ hours of battery life. Now let’s see whether that’s actually true.

Out of the box

ActivBuds S-250 come with their own carrying case, charging cable, dual port USB car charger, 3 extra sets of silicone ear tips (S, M, and L), a cable clip, and user manual.


Their black and red design is sleek and beautiful, but also a bit bulky. However, I can tell they were built really well. They actually look durable and expensive. In addition, they’re lightweight and fit comfortably thanks to their ear-hook accessories. The cable connecting the two pieces is also quite unnoticeable.

These headphones are perfect for runners and gym-goers who love listening to music while exercising. Still, if you don’t like the in-ear design, then you won’t like these headphones either.

The S-250s are not waterproof or sweatproof, which is kind of disappointing. This feature was added afterward to the new and improved version, the S-255, but more on that a bit later.

Sound quality

By far the biggest downside of these Bluetooth earbuds is their sound quality. Although their bass is heavy and dramatic, the treble leaves a lot to be desired. It’s flat and outright lacks precision. The mid-range tones aren’t that great either. And being that they are in-ear headphones, their soundstage is off, as well.

Besides, these headphones don’t have noise cancellation, especially when it comes to bass tones. Sounds such as that of an airplane engine running will definitely overpower the music on your earphones. But I guess some people don’t mind that.


The wireless connection range of ActivBuds S-250 is not bad. It can go up to 35ft. The connection is rather stable and without hiccups.

Unfortunately, the headphones have too much latency, which is typical for wireless headphones. Still, that makes it impossible to watch a movie with them. If you plan on using these for more than just music, then I suggest you go with another model of earphones.


Senso promises 9+ hours of active use and 240 hours of standby, and they only take 1.5 hours to fully charge. In reality, they last about 8 hours, which is still pretty decent. You can charge them with the provided Micro USB cable or dual port USB car charger. And it does take only an hour and a half to charge them.

2.  Senso ActivBuds S-255

Senso ActivBuds S-255 are amazing sports headphones. They’re stable and tight-fitting, they’re sweatproof and waterproof, and their battery life is great. They also have noise cancellation, which is a huge improvement from the S-250s. Besides, their value is well worth the price. They’ve definitely earned their place in this Senso Bluetooth headphones review.

If you’re an athlete looking for a pair of decently sounding earphones, but don’t want to spend a fortune on them, the S-255s are definitely for you.

As we mentioned in the previous review, the S-255s are a new and improved version of the S-250 headphones. And I have to say — Senso really did read their reviews before actually making this version. Allegedly, the S-255s have a much better sound than their previous version. The company focused on making the treble crisper, but they’ve also improved on overall sound quality.

Another improvement from the S-250s is the fact that these ones are sweatproof and waterproof. You can wash them, drop them in the water, and they’ll remain intact. However, they are not intended for swimmers, as they don’t work underwater.

Out of the box

The S-255s come with a carrying case, a cable clip, a Micro USB charging cable, and user manual. In addition, you’ll also get 3 extra sets of ear tips, in 3 different sizes (S, M, and L). And that’s not all — they also come with a set of memory foam tips.

Unfortunately, the charging cable is quite short so you might need to buy a longer one separately.


The S-255 design is quite similar to the red and black design of the S-250 headphones. These ones also have ear-hooks that will keep them in place and prevent them from falling out. Some won’t like the fact that the earbuds are connected with a cord, but personally, I didn’t mind it. These earbuds really do provide a tight fit, which is exactly why they’re perfect for athletes.

And again, these earbuds have an IPX7 rating which makes them waterproof, but they don’t work underwater.

Sound quality

Senso boasted about S-255s’ sound quality. Namely, they should be the improved version of the S-250s, with a much crisper treble, and overall better sound quality. However, I still feel like it’s not good enough.

The quality of the bass is great, although it can be a bit overpowering. I have mixed feelings about it, and I’m not alone in that. User opinions seem to be divided on this topic. Some people like the strong bass, while others don’t. It boils down to you and your personal preferences.

All in all — the sound quality is better than on the S-250s, but it’s still not ideal. If you care a lot about sound quality, then you probably won’t enjoy these headphones.


Apparently, Senso improved on S-250’s connectivity, as well. The S-255s have a great wireless range of 35ft, and their connection is rather stable most of the time. Another cool thing about these headphones is the quick-start option. Setting up these headphones takes only a couple of seconds, which I love.


When it comes to battery life, the S-255s are the same as the S-250s. They can work constantly for about 8 hours straight (or 240 hours if on standby). Additionally, they have the ability to fully charge in about 1.5 hours. For a cheap pair of earbuds, their battery is more than decent. If you consistently charge it every few days or so, you won’t have any problems with the battery.

3.  Senso ActivBuds S-270

Senso ActivBuds S-270

The Senso ActivBuds S-270 place themselves as a perfect middle-of-the-road option in my Senso Bluetooth headphones review. While they retain the water resistance and high fidelity sound from the previous earbuds, the S-255s, they come with a whole new set of features. A sleek new design, combined with active noise cancellation, transforms the S-270 Bluetooth headphones from a gym accessory into an everyday carry workhorse. You can now easily wear these Bluetooth earbuds wherever you go.

When you compare the S-270 Bluetooth headphones with the S-250s or the S-255s, you can easily see the improvements that were made in the S-270s. What used to be bulky gym Bluetooth earbuds, with barely decent audio and connection issues, became a sleek, reliable, high fidelity pair of everyday headphones. The S-270s are not an evolutionary step as they are a complete overhaul of the old design. Starting with the design, which now has a more understated, everyday look, all the way to the new onboard chip with noise cancellation, I see improvement upon improvement. The only things that were left unchanged are the IP rating and battery life, which were also great back then.

Out of the box

When you open the glossy cardboard S-270 box, you’re immediately greeted by the familiar Senso hardshell case, beneath which lie the obligatory user manual and warranty card.

I was surprised to see a 12v car charger with 2 USB ports, as well as a really interesting USB cable. The cable has both an Android and an iPhone connector. Additionally, you get 3 extra sets of ear tips (S, M, and L).


The Senso ActivBuds S-270 has a much different design from their S-250 and S-255 counterparts. The S-270 are done in a much more subdued fashion to attract customers looking for everyday carry Bluetooth headphones. Gone are the old red-on-black, aggressive, but crude lines of the older models.

Replacing them, we have a sleek, elegant black-on-grey design which permeates through the entirety of the S-270 earbuds. The earbuds are not as bulky as the older models, although there is still room for improvement.

Sound quality

Finally, we have some excellent news on the sound quality aspect. The S-270s come with a whole new audio chip, which offers some excellent new features.

The most prominent among the features is the all-new active noise cancellation. Finally, you don’t have to crank up your headphone volume if you’re in a noisy environment. The noise cancellation picks up your ambient sounds and cancels them out. You’re left with a perfectly silent environment, free to play your music at any volume you like.

Additionally, the sound signature is very balanced, and the soundstage is remarkably open for in-ear monitors.


The Senso ActivBuds S-270 uses Bluetooth 4.1 technology with CSR enabled. You should have up to 30 feet of range, with no skips or intermittent signal. Additionally, the connection uses a bit less power than before, even with noise cancellation enabled.


The S-270s use a Lithium-ion rechargeable battery, claiming to allow over 8 hours of playback time. Even though my experiences varied from time to time, I never had less than 7 hours of active use. Considering that they take less than two hours to charge up, 7-hour battery life is more than enough for me. Additionally, the company claims 240h of standby time, which is useful for people who use them only at the gym.

4.  Senso ActivBuds S-300

Now let’s move on to Senso ActivBuds S-300, one of the best sports headphones on the market at the moment. They’re quite similar to the other headphones I talked about in this Senso Bluetooth headphones review, but they’re actually one level above all of them. And the best part is — they’re not much more expensive than the S-270s. We finally got wireless headphones that we can actually call ‘perfect.’

So, in what way are ActivBuds S-300 perfect? In every way!

You see, Senso has really outdone itself when it comes to fixes and improvements. They’ve taken everything into consideration and applied it to this exact product. They are the most expensive on the list, but they still represent good value.

Senso made S-300s even more waterproof, with the IPX5 rating, which is a great step forward from the S-255s, S-250s, and S-270s. Also, this time, the headphones come with real HD sound quality, and much awaited sound precision.

No products found.

Out of the box

Much like the other Senso headphones from the list, the S-300s also come with a Micro USB charging cable, a carrying case (now with a zipper), a cable clip, a user manual, and a warranty card. In addition to all that, you also get 3 extra sets of silicone ear tips (S, M, and L), one pair of memory foam ear tips, and 3 pairs of differently sized ear hooks (also S, M, and L).


The design of S-300s is the typical Senso earbud, in-ear, with an ear hook above it. However, these earbuds are much smaller than the last generation’s earbuds, which is great. They’re also more customizable now, being that they come with changeable ear hooks and ear tips. The cable connecting the two earphones is very discrete, and it connects in the back via a magnet.

Sound quality

When you combine tight-fitting in-ear headphones with memory foam ear tips, you get an unforgettable sound experience. However, whichever ear tips you use, you just can’t ruin good sound-quality. And that’s exactly the case with the S-300s. Their amplifier is the same as the one in the S-270s, which means you get a great, balanced sound as well as active noise cancellation.


The chipset used in the S-300s is better known as CSR-8640. The CSR-8640 is a Qualcomm-made, highly efficient Bluetooth audio SoC which uses standard 2.4GHz radio technology to wirelessly transmit audio up to 30 ft away.

It supports various connection modes, such as HFP 1.6, A2DP 1.2, AVRCP 1.4, and CSR, which ensure compatibility with most, if not all, Bluetooth audio devices. Charging the headphones is easy using the standard Micro USB charging cable.

Battery life

You only need to charge the headphones once in a few days. Their battery life is more than impressive. Even though they advertise 8 hours of continuous use, I regularly managed to get up to 9 hours. That translates to 2–3 days of real-world use, which is excellent.

After an hour of charging, they’re back to 70–80%, which is great news for someone looking to use their headphones all day every day.


Senso Headphones Tangle FreeI’ve got to give it to Senso. They’ve managed to create four different products at four different price points, each one with its respective strengths and weaknesses. Choosing the winner between these four excellent pairs of earbuds was difficult, to be perfectly honest. They all offer good value for the given money.

However, one did stick out as the clear winner — the Senso ActivBuds S-300. The S-300s are the flagship of the ActivBuds line and, as such, they have all of the bells and whistles, as well as excellent build quality and great battery life. The S-300s are also the most ergonomic of the bunch, and they weigh the least. They are the most expensive, as well, but since the price difference is so minor between these four models, I don’t think we can actually call that a disadvantage. The S-300s are affordable, even though they’re the priciest of the bunch.

Sound quality is also amazing on the S-300s, which was actually surprising to me. Bluetooth headphones usually offer subpar sound quality. As a matter of fact, other ActivBuds that I’ve reviewed (especially the S-250s) all sounded horrible. But not the S-300s. In addition, connectivity issues are nowhere to be found with this model.t’s safe to say that the S-300s are the best out of all four models. In fact, they might be one of the best Bluetooth headphones on the market right now.
