Bluetooth 4.2 audio adapter for wired stereos

This compact receiver adds wireless streaming and hands-free calling to any device with a 3.5 mm aux input. It suits drivers who want to keep an older car stereo and home listeners who prefer wired headphones or speakers. The adapter pairs with smartphones, tablets or MP3 players and stays powered by an internal rechargeable battery. No software installation is required for basic operation.

Up to 33 ft range with 12.8 h battery life

Bluetooth 4.2 provides a stable link up to 33 ft without obstacles, or 30 ft in typical indoor conditions. The built-in battery delivers 12.8 hours of continuous music or talk time before recharging. A sensitive microphone captures voice clearly for calls, while A2DP streaming preserves stereo quality. One button handles play, pause, answer, reject and redial without touching the phone.

Dual pairing and adhesive mount included

Two Bluetooth devices can stay connected simultaneously so a phone and a tablet share the same aux port. An adhesive pad secures the adapter to a dashboard or desk for optimal microphone pickup. The package supplies a 3.5 mm aux cable for immediate connection to car stereos, home receivers or wired headphones. No companion app or driver is needed.

Questions about this item

How do I install the AknaCase Bluetooth 4.2 Aux Adapter in my car, and what step do people often miss?

Plug the 3.5 mm connector into the aux input, power the adapter via USB, then pair your phone using the single control button; the step often missed is holding that button long enough to enter pairing mode.

What maintenance or replacement will the AknaCase Bluetooth 4.2 Aux Adapter need later?

The internal battery delivers 12.8 hours of use per charge; over time its capacity will fade, so the only upkeep is periodic recharging and eventually replacing the whole unit when run-time drops too low.

What limit appears first during sustained use of the AknaCase Bluetooth 4.2 Aux Adapter?

Battery life caps continuous operation at 12.8 hours before a recharge is required, while the Bluetooth 4.2 link stays stable up to 30 ft indoors or 33 ft in open space.
