This is a useful accessory for cars that do not have integrated Bluetooth hands-free calling systems for use in conjunction with smartphones.

Essentially, the SoundMax F3 is a wireless earphone with an integrated microphone designed to work in conjunction with smartphones via Bluetooth connectivity. Additionally, the SoundMax F3 also includes a docking station that serves as an external speaker to support the hands-free calling feature, ensuring the safety of drivers while on the road.

Naturally, you can use the F3 independently with the headset, for example, when riding a motorcycle or camping.

To ensure user stability, the headset comes with two accessories: an ear hook and silicone ear tips.

The SoundMax F3 uses a 750mAh lithium battery, which supports full charging in 3-4 hours (similar to the headset) and allows for 22 hours of talk time and up to 900 hours of standby time. As for the headset, SoundMax states that the 65mAh lithium battery supports 6 hours of talk time and 90 hours of standby time.

The external speaker on the F3 is equipped with a 1.5-inch diameter driver with a 4-ohm impedance. To switch from headset mode to hands-free calling, users simply need to place the earphone into the recessed slot on the docking station - and immediately the headset will be securely "clamped" into the dock thanks to the magnetic mechanism, then the F3 will automatically switch the sound from the headset's speaker to the external speaker.
