Title: JVC HAW300RF 900mhz Wireless Headphones
Review: Following the initial battery charge the phones were immediately functional without tuning and with good volumn and sound and with excellent range. But upon further attempted usage the tunning had apparently drifted as tunning became very critical and somewhat difficult. I suspect that the difficulty was simply the result of a "learning curve." Overall I am pleased with the earphones.
