Core technologies and features of the Xvive U4 Wireless IEM System

2.4GHz wireless monitoring architecture: Operates in the 2.4GHz band for fast deployment, making it suitable for small gigs, rehearsals, and mobile monitoring applications while eliminating the movement limits of traditional wired monitoring.
Low-latency real-time feedback: System latency is under 5ms, effectively reducing the time gap felt during playing and singing so rhythm, diction, and performance response feel more natural.
Operating range over 90 feet: In clear line-of-sight conditions, it provides wireless transmission over 90 feet, enough for most small stages, church pulpits, and rehearsal spaces.
Mono monitoring design: Uses a mono monitoring architecture, making it easier for users to get a simple, clear, and practical personal monitor signal from the mixer.
XLR transmitter input: The transmitter is equipped with an XLR input and can connect directly to stage snake returns, mixer outputs, music players, or computer audio sources for flexible integration.
Intuitive beltpack receiver operation: The receiver is compact and can be clipped to a belt or clothing. With a large volume knob, it allows quick blind adjustments during performance.
Rechargeable lithium-ion batteries: Both transmitter and receiver are powered by rechargeable lithium-ion batteries, providing about 5 hours of continuous use per charge, enough for typical performances and rehearsals.
Ideal for solo and single-channel monitoring needs: This set includes one transmitter and one receiver, making it especially suitable for vocalists, guitarists, keyboard players, drummers, speakers, and anyone needing a personal monitor mix.
Fast setup and high portability: Compared with traditional large IEM systems, the U4 is lighter, requires less cabling, and is easier to get started with for mobile performers and small-to-medium ensembles.

2.4GHz Wireless Transmission System

Uses the 2.4GHz band for audio transmission, ideal for users who want fast setup and simplified RF management.
Especially suitable for small venues, rehearsal rooms, churches, and event stages, balancing convenience with real-world performance needs.

Performance-grade latency under 5ms

Latency under 5ms keeps vocals, rhythm, and instruments closer to real time, reducing performance disruption caused by monitoring delay.
Especially important for vocalists, drummers, and performers who need precise timing, helping improve overall performance stability.

Mono monitoring and simplified signal flow

The mono monitoring design can directly receive a combined monitor mix, which is practical enough for most live performances.
Compared with systems that require stereo routing and more complex setup, the U4 is better suited for users who want to complete monitoring configuration quickly.

XLR input and headphone output configuration

The transmitter provides 1 x XLR input, making it easy to connect a mixer AUX send, stage snake return, or other line-level source.
The receiver provides 1 x 1/8-inch headphone output, suitable for use with personal headphones or in-ear monitoring earphones.

Rechargeable lithium-ion batteries and portable use logic

Both transmitter and receiver have built-in rechargeable lithium-ion batteries, eliminating the need to repeatedly replace disposable batteries and lowering long-term use costs.
About 5 hours of battery life is very practical for a typical single show, rehearsal, or teaching session, and better fits mobile workflows.
