Review: Simple, practical, and works as expected. - bought it to add Bluetooth to an older car stereo, and it worked right out of the box. Super easy setup — basically plug and play like advertised, no app, no complicated pairing process. Connection has been stable, sound quality is surprisingly good for a small adapter like this, and switching between transmitter and receiver mode is very convenient. I’ve also used it with a speaker and an older TV, and it did the job without issues. What I like most is it gives older devices new life without spending a lot.

## Features

- Instant plug-and-play — no app, no menus, no pairing codes: Plug the C28 into any 3.5mm aux jack and it pairs with your AirPods, JBL, Bose, or Sony headphones in seconds. One button switches between transmitter mode (send audio out) and receiver mode (bring audio in). Nothing to configure — ever.
- Brings Bluetooth to any device made before wireless — instantly: Works with vintage stereos, Victrola & turntable record players, older TVs without Bluetooth, classic car aux inputs (pre-2015 vehicles), CD players, gym treadmills, projectors, and airplane seats. If it has a 3.5mm headphone or aux jack, C28 makes it wireless — no technician, no adapter tangle.
- Up to 6 hours per charge — built for daily commutes and short trips: Fully recharges in 2 hours via the included USB cable. Perfect for a daily car ride, gym session, or an evening at home. For longer journeys, charge it overnight or keep a power bank handy — it charges while it works via USB. Battery level shows on the red/blue LED indicator.
- Stable 10-metre connection in both TX and RX modes — and a 5-second fix if it ever drops: Maintains clear audio up to 33ft in open space. Compatible with AirPods (all models), most Bluetooth headphones, speakers, and car audio systems. If pairing ever fails, hold the button for 5 seconds to reset — it re-pairs fresh in under 3 seconds. No call to support needed.
- Works with virtually everything that has a 3.5mm port — phones, tablets, and beyond: Compatible with iPhone, Android, iPad, Nintendo Switch, Nintendo 3DS, PlayStation controllers, Samsung TVs, LG TVs, older Sony and Pioneer receivers, Garageband setups, and most Bluetooth speakers and headsets. One compact adapter. Dozens of use cases. No driver installation required.

### ⭐⭐⭐⭐ Works well...
*by T***C on June 7, 2026*

The C28 worked well-when it worked. Had a good 4 1/2 years of use out of it, then it just stopped working. When it worked, connectivity was simple. I could play music from my phone, plug the device into the aux input of my bass amp, plug my headphones into the phones jack, then play my bass and music at the same time with my headphones. Good purchase, will buy the upgraded version. Audio quality was good through this device.
