SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

good earphone

I purchased these headphones to listen to music at home and at work. For the most part, I use the 1/8 stereo mini dongle that comes with the headphones (connected to a DragonFly Red which is connected to my computer or my iPhone). Just for some background, Im not really into headphones for listening to music. When I used them in the past, I primarily used them for audio mixing and testing purposes. My main music listening is done w/ my stereo setup w/ some Dynaudio speakers and a REL sub, so this is my reference.

Believe or not, I went to shop to buy HD800 or HD820 model. Last week I was in Europe and felt that it is finally time to buy expensive headphones. I own Sony XM3, Audio Technica DSR7, Beyers DT770 Pro, Asus Rog Delta and among them Beyers are the best in sound quality. I was planning to test Audeze LCD-XC, LCD-2 closed, Denon D7200, D5200 and after listening several models the seller guy told me that these SENNHEISERs are best in sound / price ratio. Tell the truth I was never liked SENNHEISER models, for me they were something from out of my music universe. Yes Audeze and Denon models sound fantastic, but man, they costed 890-1400 usd price range. And here this guys insist that, just listen these, they cosu only 340 euro in Europe. Just listen, he persuaded me. Frankly speaking I went there to buy SENNHEISER HD800. which I like for their design and I select 3 models from SENNHEISER to compare. These ones (HD660), 800 and 820. I was surprised that HD800 was not fitting normal in my head, its sitting position is somehow wrong, I mean they just didnt fit / close my ears normally. Such expensive headphones and such terrible sitting ergonomics. In regard of sound they sounded good, but as far as I can hear simply little bit better than 660s. And the price difference was 4x... I thought, man, if this baby (660s) sounds so good why the hell I should pay 1400 usd for heads that just sound similarly? I have tested also new Momentum 4, which was terrible for me, I dont know but they sounded very distorted with my Astell Kern player. But these 660s... Oh my god, it was so punchy, so dynamic, so damn good! And imagine how fantastic they sound with my iBasso DX300 player which is a real monster!

They are great headphones. I listen to them while gaming on my pc and also when watching 4k UHD Bluray Discs. The Atmos sound shows very well on these.

Best investment into my home studio ever

Soy un gamer(en xbox)y me gusta unos buenos headset y estos llenaron la mayor parye de mis expectativas , los recomiendo

I write and arrange music. These are amazing studio headphones - light and completely balanced throughout the audio frequency spectrum. Their response time for fast attack sounds is amazing - thanks to the open design.

LOVE IT, DELIVERS GREAT PERFORMANCE. I am running them via RME ADI-2 DAC, and they sound amazing. Got a great deal.

Ive only just had my headphones for an hour and while they sound amazing from all the tests I preformed, the cable that connects to each side of the heads phone, in this case the left, will cut out the left channel if i move my head. Ive reconnected and Im pretty careful, just seems like a broken wire within the cable since i just have to move it a little to get it to work again

Have bought this pair for a week. My view has been changing. I have a pair of very early version of HD600, and Grado RS1i. I also owned HD650 in the past but I remember they sounded sweet but a little slow and too much colored.
