Headphones for $50 or less

New headphones are my No. 1 recommendation to anyone who wants to get the most out of their new MP3 player. (Except, of course, for those who decided to go with the Sony NWZ-A810 series.) Straight up: those janky, plastic earbuds that came with your player aren't doing you any favors. First off, they're not terribly comfortable, and they don't fit most users securely. For me, there are few things more annoying than having to constantly shove a hard piece of plastic into my ear. Then, of course, there's the sound quality issue...hollow, tiny, bassless, muffled, and hissy. I've heard it all. If you really want to hear what your MP3 player has to offer, replacing those 'buds is a must. Of course, I understand that not everyone can afford to throw down $450 on a pair of Shure SE530s, or even close to $100 on the Ultimate Ears Super.fi 3 Studio (though I can assure you that they are both worth it if you've got the dough). To that end, I've rounded up six deserving contenders that will set you back just $50 or less. There's a style here for every taste and comfort requirement, and each and every one of these selections will offer some noticeable improvement over stock earbuds.
