several people spoke up for the T615, which is a decent radio, but let me reitterate that i was able to directly compare it to the iRiver IFP-390T and the iRiver is audibly clearer, less noisy, better channel lock and stereo seperation. The iRiver has 20 station presets and runs from 1 AA for 20+ hours. The Sony uses 3 AAA's, has 6 presets, and makes a very loud BEEP every time you change stations using the presets. The iRiver costs twice as much, but you can record from radio and listen to 256mb of MP3 music, or use it as a portable data drive, etc. The onboard amp for both radios is powerful enough to drive Etymotic ER4S.
