Q & A

Q1: What makes Infinity different from most wireless earbuds?
A: Unlike 99.9% of Bluetooth earbuds on the market, Infinity supports all three Bluetooth listening modes:
1. Classic Bluetooth - Universal compatible & aptX Adaptive for good sound & low-latency;
2. Auracast - the latest Bluetooth standard for public & shared listening;
3. LE Audio Unicast - next-gen low-latency audio with mic enabled.
This means Infinity is future-ready for the next 10 years.

Q2: Can I use both pairs of earbuds at the same time?
A: Yes. You can achieve this in one of the two ways -
a. Classic Bluetooth: Use an Avantree dual-link transmitter like Relay, SoundJet R1, Audikast 3, or Oasis Plus to share audio with both pairs.
b. Auracast mode: Use any Auracast transmitter to broadcast audio to both pairs simultaneously, or even unlimited more pairs.

Q3: Can I use Infinity with Avantree Auracast transmitters?
A: Yes. Infinity works SEAMLESSLY with Avantree Auracast transmitters (like Audikast 4, C82 Aura, Oasis Aura). Pair once via Auracast, and Infinity will automatically reconnect every time you power it on—no repeated setup needed.
