| The Bottom Line | The entry-level Sony B-Series Walkman is a solid choice for the gym thanks to its ultracompact design, quick charge function, and integrated FM tuner--but beware the eye strain. | If you're looking for a sweat-resistant, all-in-one solution for rocking out at the gym, the Sony W-Series Walkman will provide just that. | SanDisk's tongue-twister of an MP3 player is a stupefying value and its practical clip-on design is perfect for the gym. | The second-generation Sony E-Series Walkman remains an excellent value thanks to its ultralow pricing, pocketable design, handy features, and great sound quality. | The SanDisk Sansa Clip+ is an excellent successor to the line, offering a fitness-friendly design with a built-in belt-clip, a simple interface, solid sound quality, and plenty of handy features--all for an ultralow price. It's an unbeatable value. |
