Vszerda 4-in-1 Bluetooth 5.1 Transmitter Receiver Wireless Adapter

SKU CH-TMR6-VJK16

Wireless audio adapter adds Bluetooth 5.1 to TVs and speakers with optical, AUX, RCA and 6.5 mm mic ports, cutting latency below 40 ms and running 8 hours per charge

  • Bluetooth 5.1 chip cuts latency to under 40 ms
  • 4-in-1 design handles TX, RX, FM radio and 6.5 mm mic input
  • 1200 mAh battery delivers up to 8 hours of playtime
  • NFC one-touch pairing connects phones in seconds
  • 30 m open-range link keeps audio stable across the room

Versatile 4-in-1 Audio Adapter

The Vszerda unit combines Bluetooth 5.1 transmitter and receiver functions with FM radio and a 6.5 mm microphone input. It suits home users who want to stream TV audio to wireless headphones or add Bluetooth playback to a wired speaker system. The built-in NFC pairing simplifies connections for compatible phones.

Simple Setup With One Cable Catch

Switching between TX and RX modes is done with a physical slider, and the Type-C port charges the 1200 mAh battery in 1.5 hours. The main friction point is that the low-latency benefit under 40 ms only activates when the paired headphones also support aptX Low Latency; standard headphones will fall back to the typical 220 ms delay.

Eight-Hour Sessions And 30-Metre Range

A full charge delivers roughly 8 hours of continuous streaming in either direction, with standby stretching to 300 hours. The Class II radio reaches about 30 metres in open space, enough for a living room or garden party. Dense walls or interference from other 2.4 GHz devices will reduce that practical distance.

Questions about this item

How can I confirm the adapter is transmitting audio with low latency after pairing?

When paired with an aptX Low Latency device the DSP decoding chip reduces delay from 220ms to under 40ms; watch the 36×8mm screen for the TX icon and listen for lip-sync accuracy.

What cables and accessories are included versus what I must source myself?

The unit provides 3.5 mm AUX and RCA input/output ports plus a 6.5 mm microphone jack and Type-C charging cable; optical cables, FM antenna and TF/USB media are not supplied.

Which mode should I choose for TV watching versus karaoke parties?

Use TX mode with optical or RCA to stream TV audio to Bluetooth headphones; switch to RX mode and plug a 6.5 mm mic into the front panel for KTV singing over powered speakers.
