eppfun Bluetooth audio adapter 10 m
Product description
If you want to add Bluetooth audio to a TV or make wired headphones and speakers work wirelessly, this eppfun Bluetooth transmitter receiver is a practical solution. It supports optical digital connection, so you can send audio without the usual guesswork about compatibility. In TX mode, it turns a non Bluetooth TV into a wireless sound source, while RX mode helps you make wired audio gear Bluetooth ready. 😊
The eppfun unit uses Bluetooth 5.1 for a faster connection profile and an effective operating range of up to 10 metres, according to the manufacturer. It also includes codec support with delay figures, plus simple controls for play pause and volume changes, so day to day listening stays straightforward. There are a couple of connection limitations to keep in mind, especially around how many Bluetooth devices can be linked at once.
Key features
This model is designed to work in two directions, depending on what you plug in. In transmitter mode, it converts audio sources such as TVs that do not have Bluetooth into an audio signal that can be received by Bluetooth headphones. In receiver mode, it can take audio from a wired setup and stream it wirelessly to Bluetooth enabled playback, including headphones and speakers.
A key convenience is the way it handles digital optical audio. The unit supports digital optical technology, which lets you connect via an optical output for a clearer route from compatible TVs and audio sources. If your TV has an optical output, this can reduce the need for workarounds and help keep the setup consistent from one viewing session to the next.
The Bluetooth performance is backed by Bluetooth 5.1, with the manufacturer stating an improved effective operating distance. The transmitter is described as supporting a 10 metre transmission distance, which is helpful if you are sitting across a room or keeping a comfortable gap between your TV and speakers. 🧩
For controls and status awareness, the transmitter receiver includes several buttons for common actions like play pause and volume adjustment. There is also an LED indicator, so you can quickly see the connection status and the compatible codecs.
One more practical point is the connection behaviour. The transmitter mode supports connection to only one Bluetooth device, and the receiver and transmitter modes do not support simultaneous connection of two Bluetooth devices. Keep those limits in mind if you plan to share audio between multiple pairs of headphones or speakers.

What you’ll notice day to day
Setup is built around common connection types, including AUX 3.5 mm and digital optical, plus USB power. In TX mode, you can use it with a TV that lacks Bluetooth and still enjoy wireless listening through Bluetooth headphones or compatible speakers. In RX mode, you can make a wired audio path Bluetooth enabled so that phone audio can be listened to without running cables.
Sound quality is positioned as a strong focus, with the manufacturer highlighting digital optical compatibility to help avoid quality degradation. For many homes, that matters most when you want a reliable link for film sound, gaming audio, or music playback while keeping the audio route tidy. 😊
There is also an emphasis on codec choice. The manufacturer notes AAC can perform better than SBC for RX, with a stated delay range of 90 to 150 ms for AAC. If synchronisation matters to you, those latency differences can affect how well lip sync feels during video.
Do note a specific limitation described by the manufacturer. This TX model does not include a built in battery, so you will be relying on the provided USB cable for power. Also, the transmitter mode supports only a single Bluetooth device connection, which can limit use cases like switching between devices without re pairing.
The package includes 1 transmitter, a USB cable, an AUX cable, and a digital optical cable, making it easier to get going across different TVs and audio setups. The unit measures 103 mm by 67 mm, and weighs 74 g, which keeps it easy to place near your TV or audio system without taking up much space.
Who it’s for
It’s a good fit if you have a TV or audio source with optical output and you want to use Bluetooth headphones without replacing your equipment. It makes sense if you also have a pair of wired headphones, speakers, or similar gear that you want to turn into a Bluetooth capable setup for mobile audio. It might not suit you if you need to connect two Bluetooth devices at the same time in a single listening session.
Better avoided if you are looking for a fully battery powered adapter for portable use. It’s also not the best choice if you want to send audio to multiple Bluetooth receivers simultaneously, since the manufacturer states the transmitter mode supports only one Bluetooth device.
