SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Easy to wear for hours. Don’t feel like they clamp my head too hard. Ear cups don’t get hot or uncomfortable. They are light, but don’t feel cheap, you could almost forget you are wearing them. Sound is ridiculously good even with the simple magni modi combo from schitt I purchased.

Compared this model with the Hifiman HE560 V4, then the Sundara, then the Sennheiser HD650. Finally, I found the winner in Sennheiser HD 660S for build quality, and excellent sound in all areas of treble/mid/bass performance.

These headphones produce the highest quality sound I’ve ever heard. I use them for both gaming & music. Amazing for both!

If I buy related products in the future, I will give priority to this store.

These headphones sound amazing, and I love the feel of the soft felt ear pads. It is most impressive when you adjust it to your listening preferences: because the HD660S is designed for a flat frequency response, I turned up the bass on the amp EQ to give the music the fullness and power that I prefer. This generates clean, deep bass when the EQ is adjusted.

I realize there are many high end headsets…. And I’m not an audio specialist, but oh my these are amazing. Lows with depth and resonance, crystal highs, clear mid tones…. Use it with a DAC and rediscover your love for music.

I listen to MOONRISE by NIGHTTEMPO. Surprisingly, I can feel the waves on both sides beating on the boat.

Muy cómodos. Sonido nítido. Peso justo.

UPDATE 10/11/2021: Pushing this up to five stars. I used to think this headset lacked some treble but this is because I came from a VERY bright and tinny headset. After listening to many songs across many genres of music and listening to non-headset audio systems I now know that this is a phenomenal product. Thank you, Sennheiser for showing me how amazing music can sound!
