High end headphone maker Audio-Technica was in Las Vegas this week to celebrate its 50th anniversary, and also entered the high-end fitness headphone market with the Apple-friendly ATH-CP500i and ATH-CP500 Sport Fit In-ear Headphones. Both have an exclusive ear-hanger design and loop support system to provide a stable, comfortable fit even during intense workouts. Congrats on making it to the big 5-0 to Audio-Technia. We look forward to putting these headphones to the test later this year.
