XviveU9 Violin Wireless System - Black
1/15
Independent shopping perspective
The Korena take
The Xvive U9 gives violin and viola players a wireless setup built around an instrument-mounted supercardioid gooseneck microphone. Its position can be adjusted after attachment, so placement is part of your setup rather than fixed. With six channels, an indoor range of up to 90 feet, and latency below 5 ms, it is configured for wireless practice or performance. Rechargeable Li-ion batteries provide up to five hours of performance, and the system uses lightweight, durable materials.
Strong match
Who this is for
- Violin or viola practice and performance where moving wirelessly within an indoor 90-foot working range matters.
- Players who want to attach and reposition a supercardioid gooseneck microphone on their instrument.
- Performances lasting up to five hours on the system's rechargeable Li-ion batteries.
Consider the trade-offs
When to look elsewhere
- Situations requiring more than five hours of performance from the rechargeable Li-ion batteries.
- Use beyond the specified indoor working range of up to 90 feet.
