Leave the phone in your bag and still get music on the bus, at the gym or on a long trip. This transistor radio earphone pairs wireless listening with FM radio and a microSD slot for offline MP3s, all from one full-size headset with a purple LCD.
All-in-one wireless headphones with FM radio and microSD playback
- Needing separate devices for radio and offline music
- Carrying a phone for every listening session
- Taking calls hands-free while on the move
Leave your phone behind and still hear everything
Stop carrying a radio, an MP3 player and a phone just to listen on the move. Tune FM stations or load a microSD card and get one wireless headset that handles it all.
Radio, card and wireless in one headset

Tune FM with one long press
Long-press the multifunction button and the headset switches to radio and starts searching on its own. The circular LCD shows the frequency as it moves, and the plus and minus keys step you through channels. It is the fastest way to get local news or music when you have no signal to spare.

Load a card and walk out the door
The built-in slot takes a microSD card up to 32GB. Insert it and the MP3 files start playing without any pairing or app. Take the card out and put it back in, and the headset picks up where you stopped. An album library that fits in your pocket costs nothing in data.

Fold it flat and pack it anywhere
The headband folds down so the headset slides into a bag next to your charger and keys. The power switch sits on the side, so you can turn it off without digging for a button. Leatherette cushions keep the fit comfortable for a full commute.
Long-press once and the radio finds stations
- 1Power on
Flip the power switch on the side. The purple LCD lights up when the headset is ready.
- 2Enter radio mode
Long-press the multifunction button. The headset searches for stations automatically and shows the frequency on the LCD.
- 3Adjust channels or switch to card
Use the plus and minus keys to move between stations. For music from a card, insert a microSD card and MP3 files start playing on their own.
The phone was never meant to do everything
The phone is always the problem
Every trip starts the same way. The phone is at 15 percent, the data is almost gone, and you still just want something to listen to on a packed bus. Streaming drains both, and cheap earbuds rarely come with a radio or a card slot. So the phone comes out, the cable comes out, and the music never quite starts.
One headset, no extra devices
The B19 takes over the jobs of the radio and the MP3 player you were carrying anyway. Long-press the multifunction button, let the headset search, and step through stations with the plus and minus keys. Insert a microSD card and the tracks start on their own. Your phone stays in the bag.
Built to live on the move
Matte plastic, leatherette cushions and a silver headband accent make this a headset you will wear every day, not one you save for home. The headband folds flat when it is time to pack. Pick a station or a playlist, put them on, and leave the phone where it is.

Questions and answers
The packaging lists support for cards up to 32GB. Use a card within that limit, formatted with your MP3 files in the root folder, and it will read. Larger cards are not supported.
Long-press the multifunction button to enter radio mode. The headset searches for stations on its own, and the plus and minus keys change channels. For MP3 playback, insert a microSD card and the files start automatically. Playback position is remembered when the card goes back in.
The packaging does not publish driver or frequency specs, so judge it on the fit and feature set. The leatherette cushions and full-size cups make it comfortable for long sessions, and the bass is on the light side. For speech, radio and everyday music it covers the basics.
Yes. The headband folds down so the headset fits in a bag next to a charger or a book. Keep the power switch off when you pack it.
A phone needs data or a downloaded library, and it drains battery fast on a long ride. Earbuds usually have no radio or card slot. The B19 covers FM and offline MP3 on one headset, so the phone stays in your pocket. If you already own wireless earbuds, keep them for calls and use this for radio and card playback.
