Qualcomm® aptX™ HD

aptX-HD audio ensures that your Bluetooth® wireless enabled device can deliver High Deffnition (HD) audio. To take advantage of this feature, please ensure that the audio source device or the transmitter also supports the aptX-HD Latency codec. To check if your device is aptX-HD certified, visit aptX’s website: www.aptx.com.

We recommend Avantree Oasis Plus to ensure compatibility with the AS90P.

Qualcomm® aptX™ Low Latency

aptX-Low Latency delivers high quality 16bit audio while minimizing audio/video syncing issues. To take advantage of this feature, please ensure that the audio source device or the transmitter also supports the aptX-Low Latency codec. To check if your device is aptX-LL certified,visit aptX’s website: www.aptx.com.

We recommend any of the following Avantree Bluetooth transmitters – Oasis Plus, Audikast, Leaf to ensure compatibility with the AS90P.

Using as a wired headphone

You may use the supplied 3.5mm audio cable to connect to a non-Bluetooth device.
Note: The control buttons, the built-in mic, and the detachable boom mic DOES NOT work in wired mode.
Note: If you wish to use the ANC function in wired mode, please turn on the headphones first.
