2-in-1 Bluetooth 5.3 Adapter

The IHDAPP OMS-M13 is a compact wireless adapter that functions as both a Bluetooth transmitter and receiver. It adds Bluetooth 5.3 connectivity to audio systems, TVs, PCs, and car stereos that lack built-in wireless support. The dual-mode design lets you stream audio from a source device to wired speakers or send TV audio to wireless headphones.

Thermals Noise and Power Draw

The unit runs on an internal 3.7V 1000mAh rechargeable lithium battery rated at 3.7W, drawing less than 40mA during operation. A full charge takes approximately 1.5 hours at roughly 1000mA current and delivers up to 10 hours in receive mode or 10 to 12 hours in transmit mode. With no active cooling, the device operates silently.

Upgrade Path and Compatibility

This adapter replaces wired-only connections by adding Bluetooth 5.3 to equipment with 3.5mm AUX, RCA, optical, or coaxial ports. It supports optical input sampling rates of 32, 44.1, 48, 96, and 192kHz at 24-bit depth and plays MP3, WAV, FLAC, and other common formats from USB storage up to 64GB. NFC tap-to-pair simplifies initial setup for compatible phones. It is not suited for users needing Wi-Fi networking, multi-room audio synchronisation, or aptX codec support.

Questions about this item

How do I install the adapter and which step do users often miss?

Connect the adapter via 3.5mm AUX, RCA, optical or coaxial input, then press the M button to select TX or RX mode before pairing; the step users miss is setting the correct mode for their source device.

What maintenance or replacement will the adapter need later?

The built-in 1000mAh lithium battery is rechargeable and rated for up to 12 hours per charge; no user-replaceable parts are specified, so the battery will eventually require professional service.

What limit appears first during sustained use?

Battery life reaches approximately 10 hours in RX mode or 10-12 hours in TX mode before a 1.5-hour recharge is needed.
