This is a great little player. Well made, tough, compact, light and with plenty of features. It has a graphics equaliser, with a few presets or you can set it to your own preference, it can shuffle tracks and folders, repeat play, etc.
The display on the player is a decent size and easy to read. Proper track names are supported, which is always better than just the filename being used. The controls are easy to work without constantly having to look at the player (such as volume control and moving tracks on or backwards). Once clipped onto your belt or even your arm with the supplied strap, the Muvo is so light that it is not intrusive at all.
The supplied headphones are fine and a clear sound is produced. Fiddling with the equaliser settings certainly proves worthwhile, but at this price point I think the sound quality is superb.
The supplied Creative MediaSource software provides a player for your PC, plus music library functions, ripping from CDs, copying to your Muvo player and all the standard stuff that Windows Media Player et al also do. You don't have to install MediaSource to get the player working with your PC, but it's not a bad application so is worth a look.
The Muvo TX support USB 2.0, so if you have USB ports of that standard transfer speeds are very quick. I have managed to fit typically 65 or so tracks into the 256MB at 128kbps quality, which isn't bad and transferring stuff to and from the player is quick and easy enough that altering your playlist isn't too much of a chore.
Power is supplied by a single AAA battery. This tends to last for about 8 hours or so and with batteries so cheap is very handy as you don't have to worry about charging the player at all, just switch the battery.
At this price, the Muvo is great value. It is a quality player with a decent amount of storage, high reliability and good battery performance. You can pay a bit more for a 512MB model with a built-in radio, but this model does a great job.
