Factors to Consider When Buying a Wireless Headphone

All of us have different standards when it comes to gadgets and devices like headphones. Therefore, I listed all the factors that affect the user’s experience for a headphone.

The different types of headphones available in the market target various types of users. It does not mean that one type is better than the other. In fact what may seem to be an advantage of a particular headphone to one person may be a disadvantage to another.

freedom of movementIn choosing a good wireless headphone, you should look into the following guidelines to learn which type is the best for you.


You have to be realistic about your budget. You can set a high expectation on an expensive headphone but lower your standard on the cheap ones. You will often get what you pay for.

As for me, I just want to buy a product at a reasonable price. Of course, I also want to get the maximum benefit at a low price as possible.


Different manufacturers placed different features among their products to meet the different demands of their market. Therefore, it is important to know the features of the product that you are looking for and make sure that you need them.

Some headphones are wireless, with cables, or with detachable cables. Some have active and good noise cancellation features, while the others do not.

By ensuring that you get the headphones with good features that suit your lifestyle and needs, you get the most value of the price you pay. It will also ensure that you will not pay more than what is needed.


Test It Out

You can use the different reviews on the products as suggestions and information to know if a particular product is a good option or not. However, you can trust your ears better than the others. If you can personally go to a store, go ahead and test the product yourself.

If in case you are buying from an online shop, learn about the product’s features and specifications. Also, read about their warranty and refund offerings.   

Read on Jargons

The headphone specifications are a bit techie but knowing them will give you an advantage. The salespeople will not easily dupe you by talking in jargons. Knowing about the specifications will also let you know more about the product that you are buying.  

Make yourself knowledgeable on the following: frequency range, frequency response, sensitivity, maximum input power, and impedance.

Learn the Pros and Cons

Knowing the advantages and disadvantages of each type enables you to see if a particular type suits your lifestyle and needs. Here are the three main types of headphones available in the market: in-ears, on-ears, and over-ears. Other than these types, there are other categories based on the headphone’s features.

Sennheiser HD 4.40 BTThe in-ear headphones are for those who want a cheap device. It offers portability because of its small size. However, it generally has the worst sound quality among the three types.

The on-ear headphones are for people who want to hear music and the ambient sounds too. Most of these types of headphones are lightweight, so it is still portable. On the other hand, most people say that on-ear headphones are uncomfortable to wear.

The over-ear headphones are for people who put more value into music or sound than portability. Most of them have huge ear pads which are the reason for its bulkiness. In fact, this type is the bulkiest among the others.

However, despite its size, it is the type that can guarantee the best sounds compared to the other types. It is still comfortable to wear although its size is big.

As for me, I prefer over-ear headphones. Even though it is bulky, it can provide me with the sound quality that I want to hear.

Moreover, wireless over-ear headphones are already available nowadays. I do not have to worry a lot about mobility because I can still take it anywhere I like thanks to its wireless feature.

If you are like me who prefers a high-quality over-ear headphone and values clear and crisp sounds, you may read on. I will share my experience with one of my favorite headphones.  

Why Do I Think Sennheiser HD4.40 Is One of the Best Headphones?

I am an audiophile who loves listening to good quality sounds. I decided to make a Sennheiser HD4.40 over-ear wireless headphones review because I think it is one of the best in the market but is still available at a reasonable price.

I am not saying that it is perfect, but it is more than enough if you want to hear the different instruments in music clearly. Aside from the sound, there are other features of the Sennheiser HD4.40 that made the product amazing in my opinion.

Sleek and Intelligent Design

ControlThe Sennheiser HD 4.40 BT is like a downgrade and cheaper version of the other models but wireless. It does not have the silver-colored highlights, but it can already do its job well. Even though its color is just plain black, its quality is also top-notch.

Looking at the Sennheiser HD 4.40 BT, its earpads are thicker compared to most of its competitors. In fact, they are even bigger than the products. I think the reason why the manufacturers made this headphone’s ear pads big is for noise cancellation purposes and for more space to give way to the bass.

The HD 4.40 does not have a good active noise canceling feature that is why it can make use of its large earpads to provide better passive noise cancellation function.

If you are looking for the controls, you will see them on this headphone’s ear cup on the right. The controls are not complicated since it does not have an active noise cancellation feature. Therefore, you can easily control the HD 4.40 headphone.

If you wear this headphone on, you might feel that it is a little flimsy because of its weight and slim headband. It is lighter compared to most over-ear headphones. I think the manufacturers created it as an advantage to make the headphone more portable. In fact, no matter how much I accidentally drop it, this headphone still works well.

Therefore, the Sennheiser HD 4.40 is durable despite its lightweight composition.

HD 4.40BT

Comfortable to Wear

Thanks to the thick padding on the ears, it makes the headphone feel comfortable to wear. Also, the padding’s material is of high-quality.

Good Sound Quality

The frequency range and response is clear and powerful. The different instruments are distinct too. You can hear the drums, bass guitars, and the cymbals nicely and smoothly.

Unlike the majority of headphones today, the bass is still audible on a deeper range. Therefore, I think bass guitar players and wannabes will love this headphone.

Its sound may not be comparable to the ones that you can hear fresh from the studio. Just like what I have mentioned before, this headphone is not perfect. You cannot expect that it can provide you an accurate and polished sound, but you can expect that you can hear a good-quality and clear sound that most people want.

Long Battery Life

You can operate the Sennheiser HD 4.40 using Bluetooth; thus, it is wireless. The manufacturers say that this headphone can run up to 25 hours which is long. I tried this headphone and took note of the hours to find out if the Sennheiser was telling the truth; I can say that this headphone did not reach the 25 hours, but was still close enough.

I can say that the length of the battery life still depends on the usage.

What Do Other Users Say About the Product?

New Sennheiser


The Sennheiser HD4.40 over-ear wireless headphones review is positive to most users. What most audiophiles love about this product is the sound quality that it produces. The bass, highs, and mids are crisp and clear. Some say that even the voice from receiving calls sounds clear too.

Moreover, this headphone prevents the sound from leaking, so you do not have to worry about the prying ears of those around you when you receive a phone call.

The users love the foldability of the Sennheiser HD4.40. This feature enables them to easily slip the product inside its carrying bag for a compact storage.

Some users compared the controls with the Sony MDR-XB950BT, but unlike this Sony headphone, the Sennheiser HD4.40’s multi-function button has a low profile in which pressing the wrong buttons will not likely happen. The only downside of these controls, according to some users, is that you can only use them when you are using the headphone through Bluetooth, which is not really a big deal for me.

Few users are not satisfied with the noise cancellation feature of this headphone. The others claim that they can still hear the ambient sound while using the headphone. I think this problem is forgivable especially if the product is available at a low price.

  • You can pair your headphone to your phone easily via Bluetooth.
  • It has above-average sound quality. The sound of the highs, mids, and bass are clear and crisps.
  • The battery may last up to 24 hours on average but still depends on the usage.
  • The headphone is easy to direct to wired mode.
  • The quality build is excellent and durable.
  • The headphone is foldable so you can easily store and take it anywhere you like.
  • The price is affordable.

  • Low profile controls for better user experience.

  • The cables are not high-quality.
  • The headband is difficult to adjust.
  • It is available in black or gray, so there is no room for personalization.
  • The headband feels uncomfortable at first because of its slim design and lack of padding.

How to Use the Sennheiser HD4.40 Headphones?

Pairing the Sennheiser HD4.40 is easy, just remember that the power button is also for the Bluetooth pairing. The other controls are toggles for play or pause or for answering calls and the volume.

You can pair your headphone by pressing the power button and hold it until the red and the blue light appear. You may now turn on your phone’s Bluetooth, and it will be paired with your headphone.

What Is in the Box?

Things to Improve

The headband is slim but uncomfortable. I believe that it needs more padding. I think it is one of the most common complaints of some users. The headband problem is just a pinch of an issue compared to the sound quality, price, and over-all comfort it offers.

In fact, there are more uncomfortable headphones on the market that are more expensive than this one.

Moreover, if you are looking for individuality, the Sennheiser HD 4.40 might not be a good option. This product is only available in black or gray colors. Unless you have your ways to design the boring colors of the headphone.

Again, the colors and the padding are just minor issues compared to the price and the quality that it can provide to its users.

Although there are flaws, some of the Sennheiser HD 4.40’s features still have room for improvement. I feel that those flaws are minor and already forgivable. The product’s amazing features outweigh its weaknesses, which I think is most important. After all, no product is perfect. Even the most expensive headphones have flaws.  

For its price, I can say in this Sennheiser HD4.40 Over-Ear Wireless Headphones review that it is one of the high-quality headphones in the market. With the sleek design, durable build, clear sound, and other amazing features, I have nothing more to ask for.
