1Mii B03Pro+ Bluetooth 5.3 Transmitter & Receiver with LDAC – TV Audio Extender + Screen Display

Elevate your home audio with flexible Bluetooth streaming

The 1Mii B03Pro+ combines transmitter, receiver, and extender capabilities in a compact unit, designed to fit seamlessly into your living room setup. Built for versatility, it lets you stream music from your phone to an older stereo, or send TV audio to wireless headphones or a wired soundbar. This is about giving you more listening options without replacing your existing gear.

With Bluetooth 5.3, you can experience stronger connections, broader compatibility, and more reliable playback across your devices. The device supports high‑resolution LDAC in both directions, so you can enjoy crisper details when pairing with LDAC-enabled players. Note that LDAC performance in TX mode depends on your paired headphones or speakers supporting the codec.

What sets it apart

• Multifunctional BT adapter: use as a pairable receiver or a transmitter to suit your room’s needs.
• High‑resolution audio: LDAC up to 24‑bit/96 kHz for richer wireless sound when conditions align with compatible devices.
• Bypass mode for shared listening: stream to both wireless headphones and a wired TV soundbar simultaneously, preserving different volume preferences.
• Clear on-device display: the built‑in screen helps you select outputs, pair devices, and adjust volume with ease.
• Low-latency potential: aptX Low Latency support can minimize lip-sync delay when both ends cooperate with LL-capable devices.
• Dedicated mode guidance: a simple tip reminds you to choose TX or RX appropriately for your scenario for optimal results.

How it helps your setup
Imagine streaming your favorite playlist from a phone to your old stereo, or watching a late‑night movie with wireless headphones while someone else uses the TV’s built‑in speakers. The B03Pro+ is designed to adapt to these real‑life moments, offering flexible connectivity without forcing you to change your gear.

Connectivity, compatibility, and setup tips

• Ports include optical, RCA, and 3.5 mm inputs/outputs for broad compatibility with TVs, soundbars, and legacy audio gear.
• Screen display assists with pairing selections and volume control, reducing setup guesswork.
• In TX mode, LDAC works best when paired with a single LDAC-enabled headphone or speaker.
• Remember: the device cannot operate as both transmitter and receiver at the same time; select the mode that fits your use case.

The 1Mii B03Pro+ offers a practical path to richer wireless audio across devices you already own. It presents possibilities rather than guarantees, inviting you to explore how LDAC, bypass listening, and easy setup can enhance your everyday listening experiences.
