Description

Add Bluetooth to the stereo, speakers or TV you already own. The adapter switches between transmit and receive, shows its mode on an OLED display and plays music from a TF card. Two items in the box, one switch, and the cables stay in the glovebox.

One compact Bluetooth 5.3 adapter that works as both transmitter and receiver, with a clear OLED display

Solves
  • Wired speakers, car stereos or TVs without Bluetooth
  • Wired headphones on Bluetooth-only sources
  • Playing music without a phone via TF card

Make any wired system wireless in one compact adapter

Tired of tangled cables in the car or a TV with no Bluetooth? This 2-in-1 unit adds Bluetooth 5.3 to what you already own, with an OLED display that shows its mode at a glance.

Two modes, one compact adapter

Transmit or receive

One slide switch picks the direction. Set RX to feed a car stereo or speaker from your phone. Set TX to send audio from a wired source to Bluetooth headphones. You do not need two devices for the two jobs.

Clear OLED status

The backlit OLED shows the active mode and channel. You see at a glance whether the adapter is transmitting or receiving, so you never guess why the audio is silent.

Music without a phone

Slide a TF card into the slot and the adapter plays stored music through the connected stereo or speaker. Handy for a trip where you want the phone battery left alone. The memory card is sold separately.

From a tangled cable to a wireless drive

The cable that never stays put

A wired-only stereo means the phone lives on a cable. The cable snags on the gear shifter, pulls the phone off the seat and cuts out mid-call. Every drive starts with the same small fight.

One adapter, two directions

Set the switch to RX and the adapter turns your car stereo or speakers into a Bluetooth receiver. Set it to TX and the same unit sends audio from a wired source to Bluetooth headphones. The OLED display confirms which mode is active before you pair.

Ready when you are

Plug the 3.5mm cable into the jack, power on and pair your phone. There is no app and no driver. The stereo keeps the sound it already had, and now it takes Bluetooth too.

Questions and answers

Will it work with my car stereo if it only has a 3.5mm aux input?
w
Wanelo · seller

Yes. Any stereo or speaker with a 3.5mm aux or line-in jack can take the adapter in RX mode. Use the aux or line input, not the mic jack, and the audio goes straight through.

Can it send TV sound to wireless headphones?
w
Wanelo · seller

Yes. Set the switch to TX, connect the 3.5mm cable to the TV audio output and pair your Bluetooth headphones. The OLED shows TX so you know the adapter is sending.

Does it play music from a TF card without a phone?
w
Wanelo · seller

Yes. Insert a TF card and the adapter plays stored music through the connected stereo or speaker. The memory card is not included, so bring your own.

How far does the Bluetooth connection reach?
w
Wanelo · seller

The claimed transmission range is 10 m. Walls and metal panels cut that distance, so keep the phone in the center console or a nearby pocket for the most stable link.

Does it have a microphone for calls?
w
Wanelo · seller

Yes, a built-in microphone handles calls. Calls run through the adapter while the phone stays in your pocket or on the seat.

Is it solid enough to live in a car?
w
Wanelo · seller

The housing is plastic with a matte graphite-blue finish and a glossy display window. It is compact, so it fits behind the stereo or in a dash pocket without taking up space. Compared with replacing a head unit, it is the lower-cost way to add Bluetooth and keep the stereo you already own.
