SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Sound quality is ok somehow no bass and hissing noise is coming ! Returning it .

Personally, the added wearing confort and less listening fatigue are well worth the upgrade. HD560s was too analytical for me and it gave me ear pain after 2 mins of listening. My setup is DragonFly Black+Apple Music.

I did an extensive amount of research on open back headphones before I purchased these. I was looking for something with a wide sound stage and accurate imaging to use for music and gaming. I am very pleased with my purchase. Every song that Ive thrown at these sounds prenominal and the imagining in these cans is perfect for tracking enemy footsteps in Fortnite, Apex, CS:GO, etc...

Amazing product from Sennheiser. Please note that the drivers in this are based on the HD 700, but not taken directly from the HD700 which one can see if one can read the frequency response graph. Anyways, there are certain people saying that HD650 are superior and there is no reason to replace it with this, well, those opinions are really biased. Dont get me wrong, HD650 is a great pair of headphone, but you cant really compare it to this because they have quite different signatures because the HD650 is somewhat a little more colored as in it is adjusted so it produces good sounds, but not staying 100% real to the original recording. On the other hand, the HD 660S is the definition of clarity, the sound is clean, crisp and stays true to the original recordings across the board. In terms of bass if you are concerned, no, they are not blow-your-head-off bassy, they are clean and punchy. In other words, it is just the right amount of bass for any music if you dont think it is enough, you can always turn the bass up in the EQ or use dac/amp with bass boost feature. To sum it up, the general idea of this headphone is a combination of the clarity of the HD700/800 (not that different) with no roll-off highs and clean sound across the board. This is a worth-it investment. (I can wear this for the entire day. Comfort wise, the clamping force that people complain about do exist, but it is pretty much gone after a week of use)

No ear fatigue like with other headphones.

I’ve come a long way, starting out with the $11 phillips earbuds to $50 earbuds, $200 headphones (beats), $400 noise cancelling headphones (sony and bose). However after a while I started to notice that some headphones had better bass, others were more clear, others weren’t loud enough, others would allow me to listen to specific instruments more clearer than others, etc. At this point I wanted something that could combine all of these aspects so I got the sennheisers.

They were not comfortable enough for me, I had to return them. The sound quality was good but the clamping force was off the charts. I have not had an issue with any other headphones (DT-880, MDR-1000X, B&O H6, HD-280 Pros).

good

The headphones are super light and sound quality is amazing.

I tried this model, the HD 6XX and the HD 600. For some reason, the sound signature seemed to be more focused on treble and clarity while the other two models seemed to have a more neutral sound but I’m not a audiophile so don’t quote me. I returned these and just stayed with the HD 600 which seems the be the right sound signature for me when gaming and listening to music. If you enjoy the sound then it may be great but everyone has different taste so buy with confidence if there is a return window as well.
