Is there an audio delay when watching video on TV? C28 uses SBC Bluetooth with typical latency of 150–200ms. For music, podcasts, and calls that is imperceptible.

If it ever wears out, or if you need a different cable length for your car aux port, simply plug in any standard 3.5mm TRS stereo cable in its place.

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 β€” 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. Review: Small yet powerful, easy to use, - I am happy with this small yet powerful device. Now, I am able to connect my AirPods with an airplane screen wirelessly without paying for a premium price such as iFly brand. The transmission is fast and clear. Easy to setup and no problem at all. ## Features - Instant plug-and-play β€” 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.
