5 out of 5 eggsAwesome

Pros: Crazy hard bass. Great sound quality. Low Frequency Response is amazing.

Second pair i have purchased because i lost my first pair.

I washed mine in washer/dryer and they still work fine.

Cons: none

Other Thoughts: How many headphones have you washed/dryed and still work perfect?

3 out of 5 eggsOk

Pros: Sounds great

Cons: Newegg or the manufacturer should have noted that one channel is longer than the other. Annoying. I wouldnt have purchased them if I knew.

4 out of 5 eggsGreat sound quality

Pros: Excellent sound quality and comfortable fit. Like all sennheiser audio products, their mids/highs are excellent and the bass isn't overwhelming.

Cons: The cord could be a little longer if you intend on running with your mp3 player in your pocket instead of in an arm band.

3 out of 5 eggsperhaps not really a sennheiser??

Pros: they get pretty loud without distortion. sound is acceptable and more comfortable than the standard iPod earphones. very tight seal with ear canal -- so great for listening in loud environments, airplanes etc. Good value for $20-$30.

Cons: a little bass heavy, but i kinda prefer it or at least got used to it -- it's better than the alternative. i wouldn't call the sound balanced. Cord is pretty short and gets tangled easy. it's made out of a rubbery material and is more difficult than most to untangle, it clings to clothing which causes the earbuds to work their way out when jogging, walking mowing etc.

Other Thoughts: I didn't actually own these, however I did have a pair of Creative earbuds (EP-630 -- google it) which look exactly like these, right down to the cord, the plug, the ring and it's dull finish. I think these are generic headphones or rebranded by sennheiser. Don't expect sennheiser quality sound b/c it has a sennheiser name. You pay for what you get and these are relatively cheap.

1 out of 5 eggsdon't buy these

Pros: they sound pretty good!

Cons: the assymetrical cable is an absolute joke, why the sennheiser design team went with this is incredible..... i sold mine after a few weeks of frustration

Other Thoughts: this is probably the reason these headphones are so cheap now,nobody wants to buy or own them

5 out of 5 eggsThe Sound Quality of Massive Over the Ears Headphones in Earbuds!

Pros: Wonderful sound quality! Excellent bass! Distinct highs and mids. Cancels all outside noise. Stays in ears easily. Cord isn't too long and doesn't catch on my bicycle and get shredded like several of my older pairs, but not too short either, no pulling on my ears.

Cons: none yet

Other Thoughts: These are by far the best earbud headphones I've used. They've actually increased the amount of work I get done. Buy them.

5 out of 5 eggsHappy, happy

Pros: Good sound, sound isolating, and comfortable.

Cons: None

Other Thoughts: I misplaced my first set of CX300's and bought the CX400's to replace them. But the cord on those is a strange two-piece thing, so I donated those to my wife when I found the CX300's were on close out.

Cons: short cord is lame

4 out of 5 eggsDecent when on sale

Pros: They're quite decent at noise cancellation. Walking around downtown with them is almost dangerous! If you can get them to fit right, they have good bass (for the price) mids are slightly recessed. Not much to say about the highs.

Cons: You can hear if the cord is bumped. But it's not as loud and crazy as everyone makes it seem. It's bearable. And if you have a little clip thing or some tape, you can pretty much get rid of all of the noise.

Other Thoughts: I wouldn't pay $40 for them, let alone $80. But if you can get 'em while they're on sale for $20ish, do it. They kill others at this price (see: skullcandy, iBuds, etc). I give them a 4, because I've definitely heard better headphones. But if it were a value rating at $20 to maybe $30, I'd give 'em 5 easy.
