Description

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.

Most Bluetooth adapters today come with screens, menus, multiple buttons, and apps you have to download just to make them work. The C28 does not. Plug it in. Press once. Done.

The C28 is a single-button Bluetooth 5.0 transmitter and receiver for anyone who wants wireless audio without the complexity. It works in two modes: transmitter mode sends audio from a non-Bluetooth source (like an old TV, record player, or car stereo) to your wireless headphones — and receiver mode brings Bluetooth audio into a wired speaker or stereo system. Switching between the two takes one button press.

Real uses our customers have found for the C28:

— Pairing wireless headphones to a Victrola or vintage turntable

— Going wireless in a pre-2015 car that only has an aux input

— Connecting AirPods to an older TV with a headphone jack

— Streaming audio on a Nintendo 3DS or Switch

— Using wireless headphones on a gym treadmill or airplane seat

— Adding Bluetooth to a classic home stereo or CD player

— Monitoring a Garageband iPad recording through wireless headphones

SPECIFICATIONS: Bluetooth 5.0. Range up to 10 metres (33 feet) in open space. Battery life up to 6 hours; charges fully in approximately 2 hours via USB. LED indicator shows power and connection status. Compatible with AirPods (all models), most Bluetooth headphones, speakers, and Bluetooth-enabled devices. 3.5mm aux jack; works with any device that has a standard headphone or aux port. Compact and pocket-sized.

PAIRING: Power on and hold near your Bluetooth device in pairing mode. The LED will flash, then go solid when connected. To reset or re-pair, hold the button for 5 seconds until the LED flashes rapidly — the C28 clears its memory and is ready to pair fresh in under 3 seconds.

If you are giving this as a gift, or setting it up for someone who does not want to learn new technology, the C28 is designed for exactly that. One button. Straightforward audio. Nothing to update, nothing to configure.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $9 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for GMCELL products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
