LED strips for status notification and connection reset are located between the positions of the 2 headsets. There is a small inconvenience of this design that when charging, you can not actively monitor the full charge of the battery for the case, forcing you to open the case yourself to check, a bit troublesome.

As a line of headphones specifically for sports professionals, the design of the headset has an additional piece to hook into the ear, helping the headset to grip more firmly even if the user has sports activities with strong intensity. much.

Sound quality

Speaking quickly about the sound quality, Plantronics BackBeat FIT 3100 is a headset for sports and ear-tip design is not completely soundproof, so the bass of the headset is pushed up by the manufacturer. Bass will create more emotions when practicing more, vibrant and passionate but much bass also encroaches on other bands such as mid and treble.

If you are expecting a neutral headset, to enjoy a variety of music, then perhaps the FIT 3100 will not be suitable.

Not to mention the open eartip design that makes environmental sound somewhat affect the sound quality of the headphones.

Battery life

The Plantronics BackBeat FIT 3100 headset pair has a battery life of about 4.5 hours, and the charging case can be fully charged for 2 more uses. This is not too long, as some of the more advanced sports headphones can provide up to 6 or 7 hours of operation.

In fact, no one practices sport continuously for 4-5 hours a day, so the 4.5 hours of BackBeat FIT 3100 is enough to use or even have leftovers. But if users are athletes participating in long-distance running, trail running, etc. lasting dozens of hours, the BackBeat FIT 3100 can not meet throughout.



If you are looking for a wireless headset that feels good to wear, experiences a stable, smooth connection, and has a powerful bass sound, then BackBeat FIT 3100 will be an extremely reasonable choice.
