SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Ive been using these with a portable DAC and Ive had nothing but pure pleasure. Just so... Yeah Im all out of adjectives. 500 is a lot. But for me worth every penny!

Rich, sweet, detailed, thoroughly satisfying audiophile sound.

If listening to hip hop or anything and want a little more punch but pure, clean sound. I love the soundstage and the imaging is top notch. I also like better than than the 800s, focal clears, and any other 600 series…but it really depends on your needs! Also, open back headphones, so that’s a big NO on noise cancellation!

These are Sennheiser and think should be renamed to Sense-Heighteners. I had a fee headphones of theirs but this is such an upgrade I heard everything again with a new light as if hearing these songs brand new again.

I used to think the sennheiser hd280s were great but these knock them out of the water. I couldn’t believe the intricate detail unveiled by these cans. Note, you’ll need a headphone or otherwise sine kind of preamp that drives the amplitude.

Ive been using the ATH M50Xs for years now and have loved them immensely however I realized they didnt handle FLAC files properly and made them sound really congested. Wanted a headphones that could reproduce the sound without that congested feel and holy hell the HD660s does just that.

Very nice sound I hear ever instrument in every song I here

Excelente calidad de sonido, cómodos, muy buena construcción, muy recomendables

spatial awareness , can sense where direction of sound is coming from. nice, clear mids, bass isnt too heavy but good enough for me. sound separation and clearer if you really pay attention to it.

Picked this up with a JDS Element. Sounds amazing! Got this as a next headphone and Im blown away. Box it came in was REALLY cool, presentation was amazing! The headphone itself isnt the best build, doesnt scream quality, theres some plastic; not even good plastic I might add, pieces that make it look like a cheap Made in China can. Its comfortable dont get me wrong ofc, its also a bonus that its light, and I use it for gaming mostly and music/ gen use. The foam isnt the softest, the velour is VERY soft, but the foam is kinda like eh, so if you have a large head (and these clamping force is very tight out of the box) it might hurt over time. I wore these 9-12 straight, not a problem like the others might; ears hurting, band digging into your head, etc. The cable is good but not great, comes with 3.5 to 6.35 adapter (for mobile, yes these get powered off my S9 very well), an extra 4.4mm balanced pentaconn cable (first time I saw that) and a 6.35mm cable already in the headphones. For me Im not a huge fan of having the cables be VERY long (most people wouldnt mind, can be pro/con for anyone), this is mostly a desk use headphone unless you wanna walk around with them on thats fine, I can, but they shouldve made it 1.2m to 1.5m long. So now I have to get a replacement cause Im forced to take all the extra cable and put it on my desk, if not is stays down and drags all that weight with it, forcing them down making them heavy. So... In conclusion GREAT sound, decent quality, and all-around amazing headphone. Would recommend to friends and family.
