Tronsmart Q20S White – Wireless earphones with hybrid noise cancellation and 60 hours of battery life

Tronsmart Q20S

Part of the Sounfii series, they feature 40 mm dynamic drivers tuned for a frequency response of 20 Hz to 20 kHz. The sound is remarkably balanced, maintaining fidelity even at high volume levels.

Hybrid Noise Cancellation (ANC)

The Hybrid Active Noise Cancellation (ANC) system uses four microphones: two external(feedforward) microphones to pick up ambient noise and two internal(feedback) microphones to monitor the sound inside the cup. This configuration allows up to 40 dB of low and mid-frequency noise to be reduced, isolating up to 90% of constant sounds such as engines or air conditioners. Three modes are available: ANC on, ANC off and ambient mode (transparency) to keep in touch with the environment.

Hi-Res certified and wired use

They are Hi-Res Audio certified, although it is important to note that this uncompressed resolution is only achieved by physical connection via 3.5 mm auxiliary cable, exceeding the bandwidth of standard Bluetooth.

Connectivity and features

In connectivity, they incorporate Bluetooth 5.3, which ensures stability within a 15-metre radius and efficient power consumption. They support AAC and SBC codecs and enable multipoint connection, facilitating simultaneous use with two devices (e.g., take a call on your mobile while listening to audio from your laptop). The built-in call microphones include noise reduction to improve voice clarity.

Battery life and charging

Battery life relies on a 500 mAh battery that provides up to 60 hours of playback (at 50% volume without ANC) or 40 hours with the cancellation system active. Full charge via USB-C takes 2.5 hours. For technical safety, input is limited to 5V / 0.5A; it is recommended to avoid fast-charging chargers to prolong cell life. If the battery runs out of power, they can still be used passively via the jack cable.

Design and ergonomics

The design prioritises ergonomics with a weight of 249 grams and viscoelastic foam ear cushions with 90° rotation. The headband is foldable and the body is IPX4 certified against sweat and splashes. Control is managed via physical buttons on the cup. They are also compatible with the Tronsmart App, which allows you to update firmware and customise equalisation.
