【Whole-Home Background Audio】Enjoy stable, synchronized sound across your home – perfect for multi-room listening in living rooms, stores, and small shared spaces.
【3 EQ Modes with Simple Controls】 Switch between Balance, Voice Clear, and Bass modes to match TV watching, conversations, or music playback. Clearly labeled buttons for power, EQ, and volume make operation simple for everyday use.
【Bluetooth, Optical & AUX Input】Stream audio from your phone via Bluetooth (works best when your device is near the transmitter), or connect to TVs and media players using Optical or AUX.
【Firmware Update Remind】The speaker may auto power off when not in use. Update firmware to keep it always on when plugged in. For best volume, set both your device and speaker to maximum.
