Listen privately to your electric guitar playing in a highly realistic manner with the BOSS WAZA-AIR Wireless System, which comprises a WL-T Transmitter and a pair of Bluetooth headphones. This is a wireless headphone system that offers Bluetooth audio streaming from smartphones and tablets, as well as tons of amp emulations and effects, all editable from your smartphone or tablet. BOSS has built these headphones with 50mm custom-made drivers to give you a full frequency response. You'll also note the onboard spatial technology to recreate the feel of an amp in a room. BOSS has even included a gyro sensor, so you can move your head around and experience a realistic shift in phase and tone. Three built-in ambience selections are on hand. The WAZA-AIR offers five amplifier emulations and over 50 customizable effects. After a quick setup procedure, you can plug your Boss WL-T transmitter into your guitar's input to hear the sound of your electric guitar transmitted to your headphones at digital wireless (2.4 GHz) ultralow latency. The transmitter battery charge will last up to 12 hours at a clip, and the headphones last up to 5 hours. Both are powered from built-in, rechargeable batteries.
