There is a “Sennheiser” lettering found on the outer part of the headband, but this lettering feature tends to come off after some time.

On the other hand, the Sennheiser HD650 features a grey metal on the outer portion combined with black padding at the inside part.

HD600 vs. HD650: Sound Quality

HD 650 is a genuine masterpiece

Sound quality is a critical feature when choosing headphones. What’s better in sound quality between these two Sennheiser headphones?

The Sennheiser HD600 features a neutral sound without any hint of discoloration, giving a natural feeling of the music. It can provide a very realistic tone of the audio you are playing. Moreover, this headphone also features a quite easy tuning but with a significant amount of detail too.

However, the Sennheiser HD650 is better in terms of sound brightness, especially on the top-end. It can produce clearer sound compared to the HD600 headphones. It also has better imaging, giving you better background audio quality.

Both headphones are excellent in their own right and choosing between them for superior sound quality will mainly depend on what type of music you are listening to. If you want to listen to music critically, the HD600 can provide the most detailed version of the sound. However, if you are more into techno, the HD650 is a great choice.

Simply put, the Sennheiser HD600 is ideal if you want to analyze music and get more of its details while the HD650 is best for audiophiles who simply want to enjoy good music for entertainment purposes.

There is just a no better choice for audio quality between the two; it just depends on what you want and your purpose for getting the headphones.

HD600 vs. HD650: Accessories

HD 650 more reliable

Both the HD600 and HD650 headphones come in great packaging. The headphones are stuffed securely between quality foam inside the box. The HD600 comes with a black case cover while the HD650 comes with a dull white one.

Upon opening, the headphones come with similar proprietary cables which are to be attached to the left and right ear cups. The cables are color coded at the end for the HD600; one is red while the other is black, to make sure that you know which end should be attached to which side of the ear cups. For the HD650, there are no colored cable ends which makes it a bit tricky to connect to the headphone cups.

Both the cables for the two headphones are replaceable but only with the same Sennheiser cables and not from other brands. Moreover, the cables have excellent quality, and you might never even have to replace them if you take care of them properly.

However, looking closely at the cables, the HD650’s feels a bit more robust compared to the HD600 which does have several complaints of being easy to break from several users.

When it comes to the build, design, and sound quality, there are only subtle variations between the two. The HD600 can produce a very detailed sound in the most natural output possible while the HD650 enhances your listening experience by adding a bit of bass and sound brightness.

While the bass for each headphone model is different, there’s no single basis for which is better between them. The choice for the kind of bass will mainly depend on the music genre you tend to listen to.

In terms of comfort and the accessories that they come with, both are quite similar, too. Both of them are made with solid and sturdy materials and while most parts and easily replaceable, they can last for a lot of years under proper care.
