Customer Ratings & Reviews

sound and balance on this set are fantastic. I am a professional composer and music editor and needed a professional set of headphones. Really appreciate these.

Have tried every gaming headset I could get my hands on and by far this was the best. You need an amp to take full advantage but by far I have been enjoying it.

OK first of all, I was aware of the pros and cons of open air overhead headphones. However, I was expecting more from these headphones, especially for the price. I did appreciate the separation and wide sound stage but I was disappointed with the level of bass which I have heard is better than other models. The one thing I could t get passed was how hot my ears got and not from the headphone warming up which didn’t happen but getting too warm from the actual headphone and this was during the winter.

awesome Headphone. Nicely acoustic sound and very nice design.

That bass tho... 5/5 highly recommend. Can buy aftermarket cord to hook up to phone if you dont like the ones out of box

Excellent item would buy again and recommend to friends and family

Ask advertise I miss short films and I have no complaints. Awesome headphones.

These are amazing heaphones do yourself a favor and grab a pair.

Got these for my husband for Christmas. He loves them!

I expected a lot for the price and brand. Im a novice user and noticed folks around me could hear the sound. I really didnt to experience anything spectacular. The treble was good but didnt get the bass impact. I paid for a new unit but the package looked like an open box and used. Big turn off

Yes yes yes yes yes yes yes yes yes yes yes yes yes

Love these headphones. They don’t hurt my ears like my beats did.

First, I'll begin with purchasing the HD 660 S2 on Amazon. They are on sale now through Best Buy so, if I waited a week, I would have purchased them through BB. Still, they came brand new so I think I can write a product review as a loyal Best Buy customer. Mechanically, I love the host of connections and adapters. With a relatively inexpensive DAC/amp, I can listen to balanced HD music at 192 KHz via Tidal. Be aware, though, the same clarity can make flawed productions of records more obvious. Some consider these reference headphones. By adding the sub-bass, they are not neutral. In fact, I didn't find the sub-bass impressive. Midrange is not very good. However, I'm a listener and can manage EQ well via SoundSource for Mac. Separation is fine. Sound stage is fine, as it should be for open eared headphones. Don't expect ANC unless the volume is up. Expect other people to hear what you're playing because these are open-eared headphones. There's nothing magical about this type of headphone. If you want closed cans, there are many great ones out there. I wouldn't give up on the HD 660 S2. I was initially annoyed by drops in cross-board frequency and was ready to return them. Pink Floyd's "The Wall" sounded horrible, with terrible drops here and there. Using SoundSource, and breaking the headphones in, have improved and/or negated those drops. I love my Sennheiser MTW4's. They are built for some high codecs but you'll have issues expecting HD from BT earbuds. I'm a Sennheiser fan, despite all the BT battery issues in the MTW's 1-3. If you want HD Res at its best, go with balanced, wired headphones with an asynchronous DAC/Amp. The 660S2 is fine for listening to HD music. It is described as a reference headphone but it is not neutral. Paying $600 is a bad idea but $500 is a tad more palatable. That's the sale Best Buy is offering right now.

I bought the 660S2s for my wife as a replacement for her Bose QuietComfort 15s. A wired headphone was necessary as we both use an MP3 that is not bluetooth compatible. I also have the same Bose/MP3 and did a short term evaluation/comparison of the two brands. This review is a bit difficult as I have to compare the new 660S2 to my Bose QuietComfort 15s that I've had for several years. I had to replace the Bose ear pads on both of our Bose units as they were deteriorating and the after-market replacements are finicky about staying in place. Thus, the first headphone search and replacement went for my wife. However, comparing the 660S2s to the Bose in a replicated A/B test has proven to show little difference in the two (to my ears). The Bose seem to reflect a bit clearer upper range and the bass is comparable. The Bose fit more comfortable as the headband on the 660S2 is too snug. However, the 660S2 pads are more comfortable. The Bose use a single-conductor, light gage wire to connect to my MP3 while the 660S2 has a two-conductor wire, slightly heavier gage and acts a bit more cumbersome. However, the Bose require a battery for speaker power and the 660S2s do not and my MP3 drives them to comfortable volume with no problem. My home audio system does not support headphone use, so I can't offer any critique with superior source(s). However, my initial intention to buy a pair of 660S2s for myself has waned, and my wife may decide to return hers. Thus, my rating of three stars is only my short experience with testing the 660S2s against a known other headphone utilizing only an MP3 as a source. Others may find the 660S2s perform very well with their audio systems. I believe I will continue my search.

THESE HEADPHONES MORE THAN SATISFIED MY EXPECTATIONS. i AM VERY HAPPY I BOUGHT THEM AT BEST BUY!
