Review: Sony Ericsson C905a
If you want to get to your music, open the AT&T Music icon, which shows you all the different music applications stored on the phone. The music player app shows you the PSP/PS3-styled interface. You can sort through your artists, albums, songs, and playlists. Once you've made up your mind what you're in the mood for, selecting it brings up the media player itself. The media player is pretty simple. Album art, if you have it, will be displayed prominently, and the song title, album and artist are all listed, as well.
With music playing, the left soft key is the options key. Here is where you can adjust the player's settings. You can turn on/off shuffle, and on/off a loop. You can also find the equalizer here (one of my favorite features). There are five presets, with no-brainer names such as bass boost, treble boost, etc. You can also manually adjust the five-band equalizer to suit your own tastes.
There are several ways to listen to music. You can use the included headset, which is of pretty poor quality, stereo Bluetooth headphones, or through the phone's external speaker. The C905a has neither a 2.5mm nor a 3.5mm headset jack. That means if you want wired headphones, you'll need to use what Sony Ericsson gives you, or find an adapter. This is a hassle.
The music will play with the phone closed, but you can't interact with it in any way. If you close the phone, you'll see the track info scroll across the exterior display, but unless you are using the controls on a stereo Bluetooth headset, you can't really do anything.
