kolitt Speaker 2-in-1 Bluetooth Transmitter Receiver

SKU CH-K3D7-107R3

A 2-in-1 Bluetooth adapter that transmits audio from non-Bluetooth devices to wireless headphones or receives audio on wired speakers from phones and tablets

  • TypeWired with Bluetooth Wireless
  • 2-in-1 design adds Bluetooth to non-Bluetooth TVs and PCs
  • One-button pairing switches between transmitter and receiver modes
  • Supports HFP, A2DP and AVRCP for high-fidelity stereo audio
  • Connect two Bluetooth headphones or speakers at the same time
  • Wired connection with Bluetooth wireless flexibility for versatile use

Dual-mode audio adapter

The kolitt 2-in-1 unit adds wireless audio to equipment that lacks built-in Bluetooth. In transmitter mode it sends sound from a TV, PC or MP3 player to Bluetooth headphones or speakers. In receiver mode it brings Bluetooth input to wired speakers, headphones or a car stereo.

Home listeners and travellers

It suits anyone who wants wireless freedom from a fixed source or who needs to stream phone audio to older wired gear. Buyers who need aptX Low Latency, aptX HD or LDAC codec support will not find those protocols here. Users requiring multi-point pairing beyond two headphones in TX mode should look elsewhere.

TX/RX mode switch

A single physical switch selects transmitter or receiver operation, determining the direction of the audio stream. The adapter pairs with up to two stereo Bluetooth devices simultaneously in TX mode and supports HFP, A2DP and AVRCP profiles for calls and media control.

Questions about this item

Which audio jack does the included RCA cable need to connect to on my TV or PC?

The RCA cable must go into the audio output jack, not the audio input jack, so the transmitter can send sound to your Bluetooth headphones or speaker.

How do I switch between transmitter and receiver modes on this adapter?

Press the single control key to power on and enter pairing mode, then use the same switch to toggle between TX mode for sending audio and RX mode for receiving it.

What ongoing upkeep does the built-in rechargeable battery require?

Recharge the internal battery via USB when the indicator shows low power; no user-replaceable cells or periodic maintenance are needed.
