Sony's WM-FX277 is a portable cassette player with an AM/FM digital tuner. Unlike most, this unit's tuner can also pick up TV audio from channels 2-13. What's more, the WM-FX277 delivers 35 programmable station presets for fast access and convenience. This Walkman includes Mega Bass technology. Also worthy of note is the presence of Sony's Automatic Volume Limiter System. When activated, AVLS keeps the music from playing dangerously loud. The WM-FX277 comes with compact headset headphones that sport over-the-ear drivers. You'll get up to 24 hours of tape playback per set of two AA batteries.
