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:

  • Classic Bluetooth – Universal compatible & aptX Adaptive for good sound & low-latency;
  • Auracast – the latest Bluetooth standard for public & shared listening;
  • LE Audio Unicast – next-gen low-latency audio with mic enabled.
This means Infinity is future-ready for the next 10 years.

Q2: How does Infinity NC compare to AirPods?

A: AirPods lead the industry, while Infinity NC offers a more versatile alternative. Infinity NC delivers about 85% of AirPods’ noise cancelling and 90% of their sound quality, while supporting aptX Adaptive, Auracast, and LE Audio / Unicast technologies AirPods don’t support. This makes Infinity NC more future-ready and compatible across more devices.

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.
