I anticipated you few weeks ago and here is my review on the sports earphones that, in my opinion, are among the best on the market in terms of practicality, performance and comfort.
Plantronics BackBeat Fit 300 are in fact Bluetooth in-ear corded headphones, joined together by a cable for audio transmission, provided with gel spare parts in different sizes for both ear-buds and auricular supports, the part that fits with the outer part of the ear to keep the grip firmly even during the training.
The cable that joins the headphones is very durable and covered in reflective fabric that provides protection from water jets or rain and visibility at night.
A detail that I really liked is the little clip anchored to the cable that allows you to attach the headphones to the shirt keeping it tight without being unbalanced during training due to the weight of the module for remote control.
From the point of view of sound performance, the Plantronics BackBeat Fit 300 allow a good degree of isolation with respect to the surrounding background noise and I can assure you that, at the volume supported with your favorite playlist, you will not be able to hear even the speaker to you, and maybe right with you, without removing one of the two earphones.
Not bad, what do you think?
