Opt’s BD825 Envy is a compact Bluetooth 1.2 compliant multimedia device that connects ANY Bluetooth technology enabled device, such as mobile phones, laptops and PMP with Bluetooth A/V services to deliver wireless connection to ANY 3.5mm stereo earphones. BD825 Envy incorporates CSR BlueCore 3 Multimedia chipset, and is a full A2DP and AVRCP featured audio player and hands free headset. For great audio reproduction at lower, safer volumes, the BD825 Envy is supplied with Opt’s 825 Element sound isolating earphones. Featuring soft silicone noise reduction ear tips and high specification speakers to produce rich bass and exceptional high end definition, background noise can be reduced by up to 20 decibels (when properly sealed) allowing users to listen to music in high levels of background noise without turning the volume up to dangerous levels. Lower volume isn’t just safer; it improves battery life and lets you listen longer between charges.
