Koss TWS250i

Fully wireless True Wireless headphones from Koss, introduced to the market in 2021. Before us are comfortable in-ear models "without legs", which provide fixation directly in the user's ear canal, thus providing passive noise isolation. Note that active software noise reduction is not provided in this model. At the heart of the Koss TWS250i headphones are dynamic drivers that provide the ability to reproduce the classic frequency range from 20 Hz to 20 kHz.

There is a built-in microphone that allows you to use the device as a wireless headset for making calls. The operation of the headphones is controlled by tapping on the case, while in this way you can adjust the volume. Pairing with the signal source is carried out via the Bluetooth v 5.0 wireless protocol, which provides a reliable and stable signal within up to 10 m. As for battery life, the “ears” can play up to 5 hours, which is not bad at all. The package includes a set of silicone ear tips in three sizes (S/M/L), which allows you to "fit" the headphones for each user separately so that they sit as comfortably as possible.
