Excerpt: Compare to x1,. I don't feel this one is an upgrade. Everything is same compare to the previous model except for the bass, which is forwarded. Enhanced bass is not my forte, so i return the product.
Excerpt: These headphones are everything you would expect from a high end pair of in-ear Headphones. The sound is amazing and doesn't overwhelm with base, if you like crazy base sound these are not for you. The headphones are light and you barely notice wearing them even after several hours of use.
Pros: Comfortable, Compact, Great Sound, Lightweight
Excerpt: Used on my Xperia Smartphone. Sound quallity, comfort and noise isolation (isolation, not cancelling but so good and no batteries) are great - if you have near perfect hearing or appreciate the best sound quality across almost any range and genre of music these are awesome.
Pros: Comfortable, Compact, Good Bass, Good Value, Great Sound, Lightweight, Stylish
Summary: Just what I was expecting them to be for that price. Simply brilliant, and an excellent alternative to my Bose over ear headphones. The trick to the sound quality is spending 5 minutes to try out the different sizes for the ear tips. The difference in sound is amazing once you fit the right ones.
AFTER 9 MONTHS - Amazing headphones (used to be £250) but now broken!

Summary: REVIEW AFTER 9 MONTHS OF USE I probably should give them 3/5 starts since they are broken. But due to the sound quality and unique design I couldn't resist giving it 4/5 starts. They are incredibly light, but I will say that the unusually shaped ear buds takes a while to get used to.
Poor build quality for the Klipsch X11i - Ear headphones
Philip Unwin, Amazon
25 April 2015
Summary: I had to return this item after only 4 months use because the cable had split where it was connected to the jack.This item is delicate and the build quality poor. This is not what I would expect from what is an expensive item. This would seem to be a common feature if you read other reviews.
