SONRU Bluetooth 6.0 Receiver — AUX/RCA Wireless Adapter

SONRU Bluetooth 6.0 Receiver is a compact adapter that adds wireless Bluetooth audio to any AUX or RCA-equipped speaker system with low latency and a 24‑hour battery life.

If you have a favorite wired stereo, bookshelf speakers, car system, or old receiver, this SONRU adapter converts it into a wireless playback device. It uses Bluetooth 6.0 and multiple HD audio codecs to deliver clear sound and reduced delay, while a rechargeable battery gives you long continuous playback. The unit supports dual-device switching and simple plug-and-play setup via a 3.5mm AUX or RCA cable.

How does the SONRU adapter improve sound and reduce lag?

The receiver leverages Bluetooth 6.0 with support for higher-quality codecs to keep audio detail intact. Its low-latency tuning minimizes sync issues between audio and video or gaming, making listening more natural. Note that performance depends on source device codec support and connection quality.

• Bluetooth 6.0 with multiple HD audio codecs for clearer reproduction
• Optimized low-latency mode for tighter audio-video sync
• Works as a receiver only (not a transmitter) to stream from phones or tablets

What battery life and charging can I expect?

SONRU's built-in high-capacity battery provides up to 24 hours of continuous playback after a full charge, which takes about two hours. That extended runtime makes it suitable for all-day listening at home, long drives, or multi-room use without frequent charging. Charging is simple using a standard USB power source.

• Up to 24 hours playback on a single charge
• Approximately 2 hours to fully recharge via USB
• Battery status and simple controls for on-the-go convenience

Can this adapter connect to more than one device at once?

Yes — the SONRU receiver supports dual-device pairing, so two sources can remain connected simultaneously. When a call arrives on a connected phone, music pauses and then resumes after the call, without needing to re-pair devices. This makes switching between tablet, phone, or laptop seamless during daily use.

• Pairs with two devices at once for quick switching
• Automatic pause for incoming calls and resume after the call
• Ideal for households with multiple listeners or shared systems

How do I install and use it with my stereo or speakers?

Setup is plug-and-play: connect the SONRU receiver to your receiver, speaker, or headphone amp using the included 3.5mm AUX or RCA cable, then pair it with your phone, tablet, or laptop. Intuitive multi-function buttons let you control playback and answer calls without touching the source device. Because it’s compact and lightweight, you can tuck it behind equipment or carry it in a bag for portable use.

• Connect via 3.5mm AUX or RCA to any wired audio input
• Simple pairing process with intuitive control buttons
• Compact form factor fits in home, office, or travel setups

Who is this for? The SONRU Bluetooth 6.0 Receiver is aimed at people who want to modernize older wired audio equipment without replacing it: owners of vintage receivers, bookshelf or powered speakers, car stereos with AUX/RCA inputs, and anyone who wants a fuss-free wireless link from phones, tablets, or laptops. It’s also useful for travelers and commuters who need a portable, long‑running Bluetooth receiver with clear sound and convenient call handling.
