Pros Rich and immersive sound quality.
Powerful bass and clear high tones.
Great noise isolation
Well balanced product at a very competitive price.
Cons Chord is a bit short if used without the extender.
Summary One of the better in-ear earphones on the market offering an excellent sound quality at a very competitive price. Great starting point for those wanting to dip into high-end audio products.
Pros Excellent bass while preserving clarity.
Cons Short (without the extension) and thin cable. When using the extension, the overall length becomes too long, requires cable management. Earbud design does not fit everybody (my colleague can't fit) so try it out first before you order.
Summary This is one of the best sounding earphones I've ever bought, I'm sure that the sound quality beats some of the lower end Shure earphones. Its hard to find a better performing one that this at this price.
Pros The bass is far better than you will hear in any other in-ear headphones, because (apparently) of the 12.5mm rare-earth magnets (others use 10mm magnets). The three different bud sizes lets you sort out the best mix of comfort and sound quality.
Cons As they are in ear, you can't talk, chew or hear anything else while listening. Also, the cord is a strange length, designed for those carrying their phone or mp3 player in their shirt pocket. For me it's either too short or too long.
Summary A few cosmetic issues with cord length and fit, but the best sound from speakers this size and price.
