SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

These sound ok but I had a pair of Audio Technica at half the price that sound better

La calidad del sonido es excelente. Por desgracia le tengo que quitar una estrella debido a que no tienen ni un mes y una de las articulaciones ya cruje cuando me los pongo o los muevo. Esto me hace dudar de su durabilidad y solo espero que no se rompan.

Comfortable. Good sound, but not 4x better than my Audio Technica M50x, or even M40x. I understand the audiophile, you always wonder if you’re missing out on better sound. You think paying more will get you there. Not always.

The two brands/models I was most interested in for the price were these and the Grado sr325x so i will be comparing these.

FYI only, I have a pair of planar headphones (much more expensive than these), but I wanted to try lighter, more comfortable, and open-back headphones again. After the package delivery, I plugged them into a Fiios player for a few minutes to test them (I had other things I should have been doing). I was able to force myself to stop the a-few-minutes test two hours later... I found them very comfortable during the two hours listening session.

First of to point out is that if the headset is too tight feeling, carefully bend it outwards. It won’t break anything as long as your are carefull the metal of the connecting bit is bendable. Super nice headphones. Works beautifully and the comfort of the large earmuffs after bending it a little to get it to fit my fat head is amazing 10/10 would recommend. I don’t regret buying these headphones at all but I would still caution people to look at comparable headsets and other reviews.

You hear it the way it is supposed to be. Great!

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.

The best headphones I own hands down.

I almost didnt get these because of complaints about the bass, but the bass is the best Ive heard in headphones! I just got these today, and the headphones were squeezing my head a little hard at first. It becomes more comfortable as time goes on. Also, adjusting it to be sure your head is touching the band at the top seems to help relieve the squeeze feeling as well. Maybe it just takes some getting used to, and they get used to the shape of your head. This is just a review after 4-5 hours of use. Loving it so far still!
