Performance: Generally really well. Shouldn't lag at all with normal usage. Should be able to handle most modern apps. I managed to get around 8000 on Antutu Benchmark. Currently runs Android 4.0.4 with Android Jelly Bean scheduled later. Not too much built in Sony useless stuff.   Camera: One of the best for a phone   Design: Pocket friendly and comfortable to hold. Nice looks   Battery life: Terrible. Half a day with average use   Sound quality: Really nice. The software equalizer settings works rather well. The pre-installed music...

The good:These are very nice looking headphones which are also very portable. They fold up into a small package for easy travel. I don't think these feel to cheap.   The bad: Upon putting these on I was surprised at how bad the sound quality was. The bass was overpowering and also a bit muddy. Mids and highs were barely there. These are expensive headphones and the sound quality isn't any better than a $100 pair ( I am comparing to my MDR-ZX600 right now ). The comfort isn't too good as well, it had a lot of clamping pressure which didn't annoy...

These are quite good sounding for the price. The sound is well balanced and nothing overpowers anything else. The design is also quite nice. The major flaw with this and most other Skullcandy products is that they pretty much break in a month. I treat my stuff well and these only survived for around 3 months.
