Debra ER-MINI Wireless In-Ear Monitor System, Rechargeable Portable Audio Monitors, UHF Free FM for Bands, Small Concerts - 44

Why do I recommend everyone to choose UHF? I explain from the following points of information.

✓UHF has better penetration ability and more stable signal transmission range;
✓The sound delay of UHF transmission is shorter, 0.2-0.3ms;
✓UHF avoids more nearby signal interference.

×2.4G is blocked, for example, if the wearer turns around, the signal will be interrupted;
×The signal delay of 2.4G transmission is too large, which destroys the user's ability to control the beat;
×2.4G is susceptible to signal interference, such as Bluetooth signals.

Wireless in ear monitors allow for uncluttered stage sets and a reliably consistent sound wherever you move. Ideal for use by singers and musicians.

Features:

1. Adds wireless audio connectivity to any active loudspeaker
2. Connect your audio source to The transmitter and it sends the signal to your receivers
3. No compromise in audio quality;
4. Perfect for multi-room venues, weddings, mobile DJ's, tricky floor monitor placement and mobile A/V

Matters needing attention:

(1)Ultra-high frequency, no delay;
(2)Mono, with a focus on midrange sound;
(3)Listening to music is not a suitable purpose;
