Active Noise Cancellation (ANC): Effectively reduces low-frequency noises like the hum of machines or air conditioning. However, it may not fully block human voices.
Transparency Mode: Allows low, natural external sounds to pass through, ensuring you remain aware of your surroundings. Voices are clear in quiet environments, but may be quieter in noisy settings.
Connectivity
Bluetooth Connectivity: Seamlessly pairs with devices, with multi-point connection support for two devices. Easily switch between devices by double-clicking the power button.
AUX-in Mode: You can use the headphones with an AUX cable, but note that noise cancelling will not be active in this mode. Also, the built-in microphone is not functional when using the AUX cable, meaning calls must be made through the microphone of the connected device.
Call Quality
Bluetooth Call Mode: Equipped with a built-in microphone, the Q20i offers clear call quality, though ambient noise may be present in busy environments.
Gaming Calls: In Bluetooth mode, playing games while on a call can impact sound quality due to Bluetooth protocol limitations that prioritize call clarity over music quality.
Multi-Point Connectivity for Calls: Easily switch between two connected devices—answer calls on the second device, or reject a waiting call by long pressing the play/pause button.
Battery Life & Charging
Long Battery Life: Enjoy up to 40 hours of playback with Bluetooth and ANC on, or 60 hours with ANC off. A quick 10-minute charge provides up to 4 hours of use.
Charging Time: Fully charges in approximately 2 hours in temperatures above 0°C.
Charging Requirements: The charger should supply 5V, 1A for optimal performance.
Other Features
Automatic Pairing: Upon turning on the headphones, they automatically enter pairing mode by default, allowing you to easily connect to your devices.
Dual Device Support: Easily switch between devices using the multi-point feature without disconnecting the first device.
