SKU CH-6YBN-81D2P

Bluetooth 5.2 transmitter and receiver with aptX low latency streams audio between phones, TVs and headphones via optical, coaxial, RCA and 3.5 mm connections

  • Bluetooth 5.2 and aptX low latency for stable, high-fidelity wireless audio
  • Switch between transmitter and receiver modes to stream to headphones or from a phone
  • Knob controls volume, bass and treble for live sound tuning
  • 5 mm AUX, RCA, coaxial and optical connections for wide device compatibility
  • Plug-and-play setup with automatic proximity pairing for quick use

Versatile Audio Bridge

The ALSEYE M12 Pro works as both a Bluetooth transmitter and receiver, letting you stream music from a phone or computer to a home stereo and send TV or projector audio to wireless headphones. It connects through RCA, 3.5 mm AUX, coaxial and optical ports for wide compatibility with existing equipment. Plug-and-play operation keeps setup simple for everyday listening.

Upgraded Control & Low Latency

This model adds a rotary knob for power, volume, bass and treble adjustments plus RGB lighting, replacing simpler button-only adapters. Bluetooth 5.2 with aptX low latency reduces lip-sync delay when the paired headphones also support the codec, making the upgrade worthwhile for late-night TV or gaming sessions where timing matters.

CD-Quality Headroom

The built-in DSP decodes multiple Bluetooth audio protocols to restore CD-quality stereo sound, comfortably handling music streaming and movie dialogue. Bandwidth limits appear when the source or sink device lacks aptX low latency support, so very high-resolution formats or multi-channel soundtracks cannot be transmitted.
