Visual inspection

The BE6i earphones use all aluminum construction for the outer case, the only elements made out of rubber are the cable coating and holder of the remote. In addition, the earphones are both water and dust proof, being IPX5 rated.


Like in the case of the BE Sport3 model, the logo of NuForce is engraved on the rear side of the earbuds.


The BE61 model uses two 10mm dynamic speakers, these have an impedance of 20 Ohm.


The end of the earbuds is magnetic, in addition, while the surface is flat, thus ensuring a better mount for the magnets when the earphones are not in use or during shipping.


The earbuds use silicon & foam ear-tips and come accompanied by six different pairs of ear-tips. Also in the bundle, there is included a pair of ear-tips that feature a NuForce proprietary design called SpinFit TwinBlade.


The earphones are connected using a short cable with a length of a approximately 58cm, where the remote for the earbuds is mounted, as well as the Bluetooth reciever.



Due to the used materials, the build of the BE6i model is good and the earbuds have a weight of 20g. The main materials used in the construction of the earbuds are aluminum for the case and rubber for the cable and outer coating.


All the functions of the earphones are accessed through the inline remote mounted on the cable. The available functions are: play, pause, mute, prev. track, next track and the commands for smartphone connection & synchronization and the on/off toggle for the earbuds themselves.

Final thoughts

The two 10mm dynamic speakers offer a powerful bass that does not cover the rest of the frequencies. The earphones offer a balanced sound, with the mid-range and low frequencies being played with in depth details, while the bass itself is strong enough.
The headphones have been tested with different styles of music and audio formats, ranging from the already classic mp3 to Flac. The signal range is good, it covers a distance of 25m. The sound isolation is acceptable, being enough to highlight the music.
The battery autonomy is approximately 8 hours of continue use while the charging takes around one hour.
In conclusion, the NuForce BE6i offers good sound quality and an 8-hour autonomy with an operating distance of up to 25m. Also, the IPX5 certification that ensures protection from dust and water is especially welcome for outdoor activities.
