Love the audio quality.. clean, sharp, bassy clarity of music. What you'd expect from Sennheiser. The volume controller slider works well, enough friction to where it'll feel tactile

Where to begin ; Volume could be higher, even when blasting player, pushing slider all the way up should yield louder volume ; Volume slider should have been where left channel and right channel separate, instead, it's about an inch below a random...

Not horribly expensive ; nice extras like a foam block to wind the wire and a coin-purse thing to carry them in ; not uncomfortable ; Mostly good sound

frequency response seems just a little 'off'. Bass and low mids seem a little boosted. The relative lack of treble kills clarity ; volume slider seems kind of pointless (volume can be cut approx. 50%). I would rather have a less expensive product...

Great sound

Too small to fit in my ears so I use part of an earplug to get them to stay in

Sound Amazing. The best earbuds you can get for under 100 period

Not SUPER loud.. but loud enough so that everyone around you can fully understand every word of the song your listening too

Delivers sound, so that's a plus. I'll say the sound is "rich," but I'm not much of a judge. Looks slick

Sometimes the soft covers fall out. The buds are a little large and it hurts my (left) ear when I put them in

Incredible sound. I didn't think you could get this depth of sound out of earbuds. There is a lot more detail than from the stock ipod buds. The bass is fairly well balanced without being overpowering and lacks the typical "tinniness ; The holder and...

The earbuds ARE bigger than usual. I have larger ears and they fit fine, so for me it's not a con - however, my wife can not use them ; I was a little worried about the covers ripping while trying to get them on - they didn't, but it was also harder to...

dang good sound @ any price! i've owned sennheiser ; headphones 4 over 20yrs.these have met my expectations.never heard of sennheiser? buy a pair and you'll be telling all your friends

none,dont know what earlier complaints about thier size ; are about,they fit myself just fine

Great sound for the price. I debated these versus the Bose earphones - I'm glad I went with these. I don't think I could justify the extra cost

none

Sound is decent for the price

Too big for my ears. It seems I lose a lot of sound because the bud does not fit in my ear completely and I have average size ears

no distortion whatsoever, great bass

slightly larger than regular earbuds, cord a little too short
