Most dissapointing buy ever!

Don't bother buying this because it's Sennheiser, there is nothing farther to Sennheiser than these headphones, they sound worst than the stock samsung hands free. I am a professional studio musician, I know what to do to avoid getting fooled by tricky comparisons and as soon as I tested this against any of my other headphones (at the same volume) I realize why people who know does not buy on the impulse of boxing week prices.

Just Fine!

Light weight and reasonable price. The sound quality is good for my taste (crisp and clean) ... while I do not have high expectations for bass, I think these headphones should meet most expectations.

Amazing Sound, Nice and Light

These are an excellent choice for the more discerning audio enthusiast on a budget. If you're looking for bombastic bass, then these headphones are NOT for you; but if you enjoy a detailed soundstage with crisp, clear low end, then I would urge you to try these out. The earpads also create a faux noise-cancelling effect, and I find they mask ambient noise better than a lot of headphones in this price range. All in all, I'm very happy with these. My only concern is how thin the cord is; it could get mangled easily during hasty travels, and they do not include a carrying case/bag for them.

Didn't like

They're super light, comfortable if you're just sitting around. But I bought these for the gym - and they don't cut it. Don't stay on your head that well. The sound, to me, is not good. My father enjoyed them, he listens to 60s,70s,80s music. I listen to rap and hip hop and dance; there is no bassline with these headphones! Completely out the window. Completely ruined the experience for me seeing as how all my songs sound awful. So if you listen to acoustic songs and just sit around, or walk, these may be ok for you. But if you're looking for active headphones to pump you up - skip these ones.

Self Study - Classroom Headphones

Reasonably priced, quality headphones. The only issue I have is the length of the wire. I had to buy extension, if the sound cards were at the back of the PC. But that has nothing to do with the quality or value of the product. If you're using them with any tablet/IPod/laptop/etc., there will be no issue
