Q & A

Q1: Will this work with my TV?
A: Yes, if the TV has a working Optical/TOSLINK or 3.5 mm AUX audio output. HDMI-only TVs are not supported. For Optical, set the TV audio format to PCM or Stereo.

Q2: Are the transmitter and earbuds already paired?
A: They are designed to work together through Auracast. Follow the included setup instructions the first time; normal daily use does not require pairing from scratch.

Q3: Can I use the Infinity NC earbuds with my phone?
A: Yes. Infinity NC also works independently with compatible phones, tablets and computers for music, videos and calls.

Q4: Can more than one person listen to the TV?
A: Yes, in Auracast mode the transmitter can broadcast to multiple compatible Auracast receivers. In Classic Bluetooth mode, Audikast 4 connects to one headphone or speaker at a time.

Q5: Does it work with hearing aids?
A: Only compatible Auracast-enabled hearing devices can receive the broadcast. Compatibility varies by model; non-Auracast hearing aids are not supported.

Q6: Can my soundbar play at the same time?
A: Audikast 4 does not provide soundbar pass-through. Simultaneous TV-speaker output depends on the TV's own settings and is not guaranteed.

Q7: Will the earbuds fit small ears?
A: Fit varies by ear shape. The secure in-ear design may feel too large or snug for especially small or sensitive ears.
