One adapter, two wireless jobs

Bluetooth 5.3 connection
Bluetooth 5.3 handles the pairing between your phone and the adapter. Once paired, the link holds through a commute without dropouts from a loose cable. The adapter also works with the bluetooth car stereo setup you already have.

One switch, two modes
Slide the TX/RX switch to RX when the adapter sits in an aux stereo or TV input. Slide it to TX when your headphones need the signal. The orange multifunction button is easy to find by feel, so you can check the mode without looking down at the dash.

Compact, transparent build
The smoked shell lets you see the circuit board inside, and the matte black body keeps the outside plain. The gold-plated 3.5mm plugs and the flexible curved cable bend along a dash or console without pulling on the connector.
Set it up in three steps
- 1Plug into the aux port
Insert the gold-plated 3.5mm plug into the aux input of your stereo, TV or speaker. Route the curved cable along the dash or console so it stays clear of moving parts.
- 2Set the TX/RX switch
Use RX when the adapter feeds a stereo or speaker from your phone. Use TX when the adapter sends audio from a wired source to your headphones.
- 3Pair your phone or headphones
Turn on Bluetooth on your phone or headphones and select the adapter. Pair once, and it reconnects on the next drive or session.
Wired gear, wireless in one step
The cord that comes with the commute
Every drive starts the same way. The phone sits on the dash, the aux cable runs across the console, and every bump pulls the plug a little loose. Headphones at a hotel do the same thing, snagging on the nightstand and the TV stand.
One small adapter changes it
The unit plugs into the aux port and the switch decides its job. Set it to RX and the stereo receives audio from your phone. Set it to TX and your headphones pair with the same box. You do not replace the stereo or the TV to get there, and the adapter stays small enough to leave in a bag.

Quiet drives, free headphones
The commute turns into hands-free music and calls with the phone out of reach. At home the cable is gone, and you can watch late at night on your own headphones. Once it is paired, the connection just runs in the background.
What to expect, step by step
- First usePaired in minutes
Plug into the aux port, set the switch to the right mode, and pair your phone. Most setups connect on the first or second try once Bluetooth is on.
- 3 usesRoutine feels natural
After a few drives or sessions, switching modes and reconnecting becomes automatic, and the cable stops being part of your routine.
- 30 daysWired gear feels wireless
Daily commutes and home listening run without cables, and you stop thinking about the adapter at all.

Questions and answers
If the stereo has a standard 3.5mm aux input, yes. Plug the adapter into that port, set the switch to RX, and pair your phone. Stereos with only a cassette deck or a radio and no aux jack need a different route.
Yes, as long as the TV or speaker has a 3.5mm audio output or aux input. Use TX to send TV audio to your headphones, or RX to feed a wired speaker from your phone. aux input bluetooth adapter models cover the same setups.
Use the TX/RX switch on the body. RX receives audio from your phone and sends it into the aux port of a stereo or speaker. TX takes audio from the aux source and sends it to wireless headphones. Change the switch, then pair again if the link does not come up.
Basic dongles give you one mode, so most buyers end up owning two of them to cover the car and the headphones. This unit covers both in one compact body with a gold-plated connector, a flexible cable and a transparent shell. Over a year of daily commutes, one adapter costs less than replacing a working stereo or buying a second dongle.
It draws power from the device it is plugged into, so there is no separate battery to charge and no cable to track down. Keep the switch set to the right mode and it runs whenever the host port has power.
