SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

This is my second purchase of Sennheiser sound muffs.

Amazing product from Sennheiser. Please note that the drivers in this are based on the HD 700, but not taken directly from the HD700 which one can see if one can read the frequency response graph. Anyways, there are certain people saying that HD650 are superior and there is no reason to replace it with this, well, those opinions are really biased. Dont get me wrong, HD650 is a great pair of headphone, but you cant really compare it to this because they have quite different signatures because the HD650 is somewhat a little more colored as in it is adjusted so it produces good sounds, but not staying 100% real to the original recording. On the other hand, the HD 660S is the definition of clarity, the sound is clean, crisp and stays true to the original recordings across the board. In terms of bass if you are concerned, no, they are not blow-your-head-off bassy, they are clean and punchy. In other words, it is just the right amount of bass for any music if you dont think it is enough, you can always turn the bass up in the EQ or use dac/amp with bass boost feature. To sum it up, the general idea of this headphone is a combination of the clarity of the HD700/800 (not that different) with no roll-off highs and clean sound across the board. This is a worth-it investment. (I can wear this for the entire day. Comfort wise, the clamping force that people complain about do exist, but it is pretty much gone after a week of use)

Normal la calidad es tal cual presentan

The Sennheiser veil is a real thing, and if you dont mind it, these cans are Cherry.

Amazing sound. Defintely an upgrade from the m50x.

These headphones sound more detailed than my AR planar magnetic headphones. They also have better imaging, and it is excellent. Theyre a little less comfortable than I expected, but that may change with time. By the way, the AR phones cost $600.00 when new, though I bought them for $300.00. I think the HD 660 S are worth the price and I highly recommend them.

Audio is an interesting beast. Certain sounds appeal more to certain people, others might like different sound profiles. Theres really no way to pinpoint what is the best pair of headphones unless youre going into the obscenely high-end in price and quality.

Once you purchase a quality product like these 650s... Youll realize the extra noise other headphone companies are trying to put into your ear.. These are not and in no way are they advertised as noise canceling.

Good but 6xx still better overall value

Sound amazing!
