Pros: everything is great from this player
Cons: the only issue, is the recharging cable..
IMO, the Cowon J3 is the company's best device/price. It offers an excellent sound and compatibility with almost any file you want to play on it. It's also capable of driving all but the most obscure headphones to satisfying levels of loudness, and relatively excellent battery life. However if you're just looking for a device that does one thing -- play music really and extremely well -- then the Cowon J3 is an excellent option.
