Unique Melody / UNM-0935

Unique Melody U-Free is a completely wireless earphone that allows you to experience beautiful, airy, three-dimensional sound using two vibrations: air vibration and bone vibration.

■Air vibration and bone vibration
U-Free is equipped with a highly durable and high magnetic force 10mm carbon nanodynamic driver + silver palladium piezoelectric bone conduction driver. It manipulates two types of vibration to provide three-dimensional, surround sound. The high-impedance 10mm carbon nanodynamic driver is highly conductive, lightweight, and features a deep and wide sound field. Equipped with a high-output double-balanced output device on the chip, it can efficiently generate high-impedance drivers. With the newly developed PBVTU technology, you can experience the way sound travels through air conduction and bone conduction, creating an immersive three-dimensional spatial expression.

■Clear call
Equipped with advanced multi-directional microphone. The latest CVC technology filters out background noise so only your voice can be heard during a call.
[Comfortable Wear] The manufacturing know-how of custom IEMs, which are made to match the ear shape used for ear monitors, and the ergonomics of the case create a comfortable feel and fit. Ear tips made of newly developed medical grade highly transparent silica gel are gentle on human skin and fit securely in your ears. By attaching the ear tips deeply to the nozzle, the area that touches the ear increases, bone conduction efficiency increases, and the ear tips deliver sound directly without blocking sound conduction.

■Waterproof
U-Free is IPX5 sweat and water resistant, so you don't have to worry about getting wet whether you're at home, on the go, on your commute, or during a sweaty workout.

■UM Smart Sound App By downloading the UM Smart Sound app, you can easily customize modes such as switching modes, operating touch buttons, switching low-latency game modes, and EQ.
