Sennheiser is one of the leading brands when it comes to headphones, and HD 650, as well as HD 600, justify its position as one of the leaders in this segment.

Let’s do a detailed comparison of these two headphones across different aspects to understand which is better.

Sennheiser HD 600 vs HD 650: Pros & Cons and Verdict

Both these are flagship models as they set the standard for being the top headphones for audiophiles. Surprisingly, both of these headphones have been around for a long time and they continue to rock the headphone market. HD 600 debuted in 1997 while HD 650 entered the market in 2003. The fact that we are talking about these headphones even twenty years later reflects their fantastic track record.

Since both these headphones are equally good, which one to buy? Let’s compare them across different features to make your decision-making easier.

1. Design

In terms of design, both the headphones are similar in many ways. Both have a dynamic and open design and weigh identical at 260 grams.

At the same time, they also differ a bit in the design. HD 600 is a mix of black and blue intertwined to give you a marble finish. This design is not so appealing to many people, as the marble look is kind of outdated and not preferred. Also, the lettering “Sennheiser” on the outer side of the headband makes it stand out. After some time, the lettering tends to come off as well and this is definitely something that Sennheiser could have done better.

Otherwise, the build quality of HD 600 is solid though it could have been more elegant as well.

HD 650, on the other hand, comes with a greyish metal on the outside with black padding on the inner side. This colour combination is more subtle and pairs well with any dress. The metal borders on the outer side of the ear cup add a nice touch of elegance to it.

When it comes to ear cups, both are equally large and comfortable. The large ear cups make it ideal for any size ear and they clamp down comfortably without putting too much pressure on the ears.

Also, the good quality padding ensures that the ears don’t touch the drivers at all and this makes these headphones super comfortable to wear for long periods of time. The 650 has a slightly thicker border on the pads when compared to 600, but that makes no significant difference at all.

Also, the headbands are adjustable in both the headphones and this makes it perfect for anyone. Whether it is for kids or adults, the fact that the headbands can be adjusted makes it more versatile.

One feature that needs to be mentioned here is the open back design. As a result, there is no noise isolation and sound leaks out of both the headphones.

Time for the verdict – HD 600 or HD 650? Definitely, HD 650 because its design is more elegant and blends well with any costume. The marble design is a big no-no for many people and the lettering is also not so great. So, HD 650 is the winner in design.

2. Sound Quality

Sound quality is a critical aspect as this is exactly why most of us buy headphones!

When it comes to HD 600, the sound is neutral without any kind of colouration. This gives a very natural feel to the music and makes them sound just as it is. This is why the music you hear from it is a lot more realistic when compared to other headphones. In addition, its tuning is easy and gives a lot more detail than you would expect from a pair of cans.

When you listen to vocals, you are better of them listening to them in HD 600 because they sound a little bit better and emphasize on the vocals better than HD 650. It even helps you to isolate the vocals and enjoy them better.

Another difference between the two is in terms of brightness. The sound from HD 650 is definitely brighter, especially on the top-end. Also, the sound tends to be a little bit clearer in 650 than in 600. Also, HD 650 has better imaging and you can hear your surroundings a little bit better.

Sounding bright on the top-end is not always a good thing, as you’ll realize in HD 650. Typically, when the top-end is bright, you will lower the volume and this means, you’ll miss out on the low range music, especially the detail. So, this is something to think about.

If you are not particular about the detail, 650 is good as it can really get you moving with its bright sound. On the other hand, if you like the detail in your music, 600 is a better choice.

The bread and butter of both these headphones is their mid-range. They sound great and natural. Also, both have a good mid-bass, but neither of these has sub-bass, and this makes it a not-so-right choice for bass heads.

What about the bass? Both are good and have tight bass. You can hear the drums and their reverberations clearly and this adds another layer to the whole listening experience. The 650s, especially have a punch in the lower segment which the 600 lacks.

But then, the 600 has a strong bass which is not a boosted one because the idea behind making 600 was to give a neutral feel to music without having any add-ons. 650, on the other hand, has that little bit of brightness and bass, which enhances the experience. If you plan to listen to bass for long periods of time, go with 600 as they make it neutral and more enjoyable than 650.

4. Comfort

Both the headphones are comfortable to wear as they come with excellent padding on the inner sides to ensure that you don't feel fatigued even if you end up wearing it for hours together. One difference in terms of padding is that HD 600 comes with four small pads. You can see four little bumps on the inner side of the headband. This was designed to ensure that there is a good flow of air, so you don't feel hot sports or sweaty after some time.

HD 650 has two large bumps instead of four in HD 600 and this makes HD 650 slightly more comfortable to wear. Generally speaking, these headphones are average in comfort when compared to a few others available in the market today.

When you wear these headphones, you definitely feel them. There are some headphones in the market that are so comfortable that you forget you're wearing headphones at all in the first place. Both HD 600 and HD 650 don't belong to that category. You definitely know you're wearing headphones because they clamp down on your ears. In fact, one common complaint about these headphones is that they clamp down too much and this makes it feel uncomfortable for many users.

That said, you get a good fit because the ear cups are stiff and don't sway as you move. Also, they are not too large or bulky and these aspects make it ideal for gaming sessions.

Overall, both the headphones score average when it comes to comfort, but they give a great fit. There is a little bit of room for air circulation, so you don't feel sweaty while wearing it for long periods of time.

Which is better? Hard to say because both are equally good in terms of fit and good when it comes to comfort.

5. Cost

While the prices of HD 600 and HD 650 are quite high, you can get them at cheaper rates on Amazon, thanks to the many deals that keep happening.

There is not much of a difference between the two Sennheiser's. Does price of HD650 justify the features of the headphones?

Not really. It would just depend on your preferences for sound and look and feel. HD 650 is definitely more comfortable and sounds brighter when compared to HD 600. Also, a personal opinion is that HD 650's simple and plain finish is better than the marble finish of HD 600.

But to answer the question of whether the price difference justifies the features, it totally depends on you. If you like a better finish and brighter sounds, it justifies the difference.

Also, if you're not particular about critical listening and want a more "fun" headphone that doesn't point out to the flaws in a recording, the higher price tag is justified.

If none of this is convincing enough, then HD 600 is a great value for your money.

Sennheiser HD 600 - Pros and Cons

Sennheiser HD 650 is not all perfect, as it comes with some drawbacks as well. It is important to know these shortcomings, as they will help you to make the right decisions.

Has one of the highest levels of accuracy and transparency	Sometimes, these headphones can be too smooth
Mid-range tones are warm and smooth	Treble needs to get better

These are the pros and cons that could maybe help you to make a quick decision, especially if you're pressed for time.

Closing Line

So, it is time for the final verdict. Both the headphones are fantastic and can greatly enhance your listening experience. There are only subtle variations between the two when it comes to sound quality. HD 600 is neutral and doesn't add anything to enhance your listening experience while HD 650 adds that little bit of brightness and bass.

But, this addition doesn't augur well always and is not necessary too in many cases. This is why you will have to turn the volume down a bit when you hear 650 for a long period of time. When you turn down the volume, the lows are not so audible. So, 600 is definitely better there as it is neutral.

The bass is slightly different, but it is hard to say which of the two is better. Guess it just depends on what kind of bass you like and what genres you prefer listening to.

In terms of comfort and accessories, both are equally the same. But in design, 650 is better than 600. Both are durable though and are made of solid materials. Again, the fact that they have been around for more than 20 years speaks about their quality.
