Avantree VoxAmp Duo Portable Wireless Voice Amplifier Microphone & Speaker Set for Classroom, Small Events Parties, USB Recording Playback, 30W Clear Rich Sound, 14H Battery

DESIGNED FOR SMALL INDOOR GROUPS — Amplify your voice for classes, training sessions and presentations. Designed for portable, small-group use; large venues, loud crowds and high-volume events require a larger PA system. HANDHELD AND HEADSET MICROPHONES INCLUDED — Choose the headset for hands-free teaching or the handheld microphone for presentations. The included microphones connect wirelessly to the speaker, so you can speak without a microphone cable. COMPACT SIZE—CHECK BEFORE YOU BUY — The speaker measures approximately 6.69 × 8.15 × 3.86 inches / 17 × 20.7 × 9.8 cm (W × H × D). Review the dimension image to make sure its size matches your expectations. VOICE, MUSIC AND LOCAL RECORDING — Play music from your phone via Bluetooth, or use USB/TF media for playback and recording. Microphone and music volume can be adjusted separately. USB recording saves to removable media; this product does not function as a computer USB audio interface. RECHARGEABLE AND READY FOR YOUR ROUTINE — Speaker battery life is up to 14 hours at 50% volume; actual runtime varies with use. The set includes the speaker, handheld microphone, headset microphone, USB-C charging cable and carrying strap. Charge the speaker and microphones before first use, then start with MIC volume low and increase gradually.
