One transmitter. Endless receivers.
Plug VOCE+ TX into any 3.5mm source — phone, TV, mixer, hearing-loop input. It encodes your audio in LC3 and broadcasts it as Auracast™. Anyone with a VOCE+ RX, or a 2024+ phone, hearing aid, or pair of earbuds, can tune in.

THE TECHNOLOGY
The first universally compatible next-generation audio adapter.
AURACAST™
One source, unlimited listeners.
Auracast™ is the new Bluetooth SIG standard for one-to-many audio broadcast — like radio, but in HD and on any 2.4 GHz device. Airports, theatres, gyms and lecture halls are rolling it out worldwide.
LC3 CODEC
Higher quality at half the bitrate.
LC3 is the LE Audio codec replacing SBC. VOCE+ encodes at up to 48 kHz / 32 kbps — closer to FM-quality, with half the battery drain and a fraction of the latency of legacy A2DP.
LE AUDIO
Built on Bluetooth 5.3 LE.
Lower energy, lower latency, multi-stream — the same backbone modern hearing aids and earbuds already use. VOCE+ talks to them natively. No app required.

If it has a 3.5mm jack, or it's made after 2024, it works.

Questions, answered.
What's Auracast™, in one line?
It's a new Bluetooth standard for one-to-many audio broadcasts — like having a tiny FM station that any modern hearing aid, earbud, or phone can tune into. VOCE+ TX is one of the smallest Auracast broadcasters made.
Do I need a VOCE+ RX if my phone or earbuds already support Auracast?
No. If your device is from 2024+ and lists Auracast or LE Audio support (Pixel 8+, Galaxy S24+, modern Phonak/Oticon hearing aids), VOCE+ RX is optional. Use it only for older or wired gear.
Is the latency really 50 ms?
Yes — that's the LC3 encode + radio + decode budget end-to-end on the LE Audio stack. Compare to ~180 ms on traditional Bluetooth A2DP.
What's the +3dB gain mode for?
A TX-side amplifier optimised for hearing-assistance use — boosting voice frequencies into the comfortable-listening range.
Does it need an app?
No. Pairing is standard Bluetooth LE. We offer an optional companion app for firmware updates only.
What's in the box?
1× VOCE+ TX or RX, a USB-C charging cable, adhesive magnet pads, and a quick-start card.
What's the warranty?
One year against manufacturing defects, worldwide. 30-day returns on unopened orders.
