Xvive Audio T9 In-Ear Monitors

Featuring dual balanced-armature drivers, the T9 In-Ear Monitors from Xvive are designed to deliver an audio performance rivaling a customized set of earphones, but at a much more attractive price point for musicians and music lovers. The unified crossover has been engineered to ensure that each driver is only sent the frequencies it is capable of accurately reproducing. The low-frequency driver provides powerful mid/bass down to 20 Hz, while the custom-tuned, custom-ported micro tweeter supplies high frequencies up to 16.5 kHz, almost the full range human ears are capable of hearing.

The T9 delivers a clear, natural, and unhyped sound that ensures musicans can trust their mixes and recordings. Audiophiles will appreciate the headroom to accommodate customized EQ settings from source material, letting you boost the bass or dial in more high end without having to worry about distortion. The detachable 3.9' cable connects to a wide range of audio gear and mobile devices via a common 3.5mm TRS connector; a 1/4" adapter is also provided.
