SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Sent a faulty product

Ill be comparing it to the HD600 which I bought at the same time to try. TLDR: Im keeping the HD600 and returning these.

Great headphone for EVERYTHING. (GAMING, MOVIES, MUSIC,PRON :v)even if the media source has bad quality, they would make them sound incredible, melt your ears for once in your life. Definitely try 24 bit flac files for best results.

Sound is amazing, build quality is superb and comfort is perfect. Using them mainly for gaming/music powered by a sound blaster AE-9 soundcard.

As someone once wrote in their review... these headphones are so light you can absolutely forget theyre on your head. If you own multiple headphones as the typical audiophile would... these are a must have. You know when you switch to another headset how light the 660s are! Its crazy.

No ear fatigue like with other headphones.

This is a huge upgrade from the headphones Ive had before. Ive gone from Hyperx cloud revolvers, V-moda Crossfade M-80s, ATH-M50X to these babies. The M50x sounded too clinical and I didnt enjoy them much. The 660s still sound veiled but are much more fun than the M50x. Because of the veiled sound I feel like something is missing even though Im hearing things I never heard before. I love these headphones but I think I just prefer a warmer sound. The headphones are amazing but lacking at the same time. I find it hard to describe because audio such a personal perception. I highly recommend them but you might not be wowed depending on the type of sound you prefer or are use to.

I was expecting better fit, better sound than what these delivered. Could not wear more than 90 minutes (band hurts the head). Sound quality better than Bose but that’s the limit. Regret purchase.

I use them for gaming, they are a significant upgrade from any gaming headset you can buy, ive owned them all. they are comfortable as heck. noise canceling is not great but really thats not what you bought these for. enjoy.

Went from HiFiMAN Sundara, to Beyerdynamic DT1990 Pro, to Sennheiser HD 660 S.
