"Truly amazed by the sound quality"5.0 starson by nmoisan
Pros: Absolute clarity and great sound spectrum. They are very comfortable and convenient to travel with. By far the best earphones I have purchased.
Cons: The only real con is that I have built my mp3 collection on 192kpbs (a long time ago!) and it's now way too low quality. I hear all the flaws in the sound. Other than that, they might be a bit expensive. I had a great deal at 150$ at Sony Store.
Summary: I would consider myself as a big time audiophile. I also travel a lot and big headphones are not convenient or suitable for me. I have been looking a long time for the best in-ear headphones but I don't want to pay 500$. I have owned multiple Sony, Bose, Sennheiser in-ear headphones and none would even get close to the XBA 4 in terms of sound balance, quality and price vs value. I am truly impressed by the clarity of the sound, especially when you listen to a high quality mp3.
Of course it's impossible to expect Beats like bass and I don't really think it's good anyway. With the right settings, you'll get a nice well-balanced bass. Treble might a little high sometimes but it doesn't affect the sound quality.
Before the purchase I have tried the Bose Quiet Comfort 20, the Sennheiser IE 80 and the Denon AHC400. For sure sound perception is something personnal and although the Sennheiser were nice, they are not worth the double price. I had the XBA 4 for 150$ on sale at the Sony Store. At this price, it's a most definite no brainer
