GMCELL C28 Bluetooth 5.0 Transmitter & Receiver – 2-in-1 3.5mm Aux Adapter

Bring Bluetooth to your favorite devices with the GMCELL C28

The GMCELL C28 is a compact, 2-in-1 Bluetooth transmitter and receiver that plugs into any standard 3.5mm aux jack. It’s designed for busy days and relaxed evenings alike, offering a simple, plug-and-play experience without apps or menus to navigate. From the moment you connect, you’ll notice a clean, reliable wireless option that complements your existing audio setup rather than complicating it.

Two modes, one tiny device

Switch between transmitter mode (send audio from your non-Bluetooth source to Bluetooth headphones or speakers) and receiver mode (bring audio from a Bluetooth source into a non-Bluetooth device). A single button handles the mode toggle, so you can adapt on the fly without fumbling with settings.

What you can wirelessly connect

• Vintage stereos, Victrola turntables, and other legacy audio gear with a 3.5mm jack
• Older TVs, CD players, projectors, gym treadmills, and classroom equipment
• AirPods, Bose, Sony, JBL, and most Bluetooth headphones or speakers
• Gaming controllers, tablets, phones, and a variety of media players and receivers

• Home entertainment setups for TV time, dinner music, or background audio
• Travel or commute scenarios where wireless listening would enhance comfort
• Creative or learning spaces that benefit from moving audio between devices
• Public or shared environments where easy Bluetooth access matters

All-day battery with quick recharge

The C28 runs up to 6 hours on a single charge and recharges in about 2 hours via the included USB cable. A handy LED indicator communicates battery and connection status, helping you plan usage between trips or daily routines. If you’re pressed for time, it can continue charging while it operates when connected to a power source.

Stable, friendly performance

Enjoy a dependable wireless range of up to 10 meters in TX and RX modes, with a built-in 5-second recovery option if a drop occurs. It’s designed to re-pair quickly when needed, so you can get back to listening without interrupting your flow.

Effortless compatibility, minimal setup

Because no drivers are required, the C28 fits neatly into existing systems—from iPhone and Android devices to Nintendo Switch or older home entertainment gear. It’s a compact, all-in-one adapter that reduces clutter and keeps your audio experience simple and flexible.
