Foreword: NuForce BE Free8

So-called "True Wireless" in-ear headphones, which renounce any cable, are at the latest since the Apple AirPods on everyone's lips. With the NuForce BE Free8 Optoma released its own implementation of a wireless in-ear, which is based optically on the "true-in-original wireless" in-ear, the Bragi Dash.


Design, workmanship and delivery

A true wireless in-ear like the BE Free8 requires one sophisticated designbecause all the technology is housed in the earphones. At the same time, the housings should be compact and the weight of the earphones should be as low as possible in order to be able to offer good wearing comfort.

The case shape of the BE Free8 is adapted to the ear anatomy. The cases are made out polycarbonateThat's why a single earphone just once 7g brings on the scales. After Degree of protection IPX5 is the in-ear "Against water jets from all directions" geschützt.

Earphones with charging case

Despite the high-gloss optics, Optoma pursues a comparatively moderate, unobtrusive design with the BE Free8. The structure of the earphones is kept simple. A smart touch operation, as supported by the Bragi Dash, does not exist. Instead, the BE Free8 is over two tiny pushbuttons operated, which are marked with the respective carrying direction. As a design feature, each earphone is equipped with an LED strip, which can be used to read the operating status. When switched on, the LED strips light up white. In the pairing mode, these in turn flash red.

The quality of workmanship of the NuForce BE Free8 is still the price, although the earphones and the case seems rather cheap because of the many plastic. Of the What's in the box includes the two earphones, the charging case, a MicroUSB cable, five pairs of SpinFit CP100 / CP350S ear pads in sizes XS / S / M and a user manual.

The commissioning of the BE Free8 is no different from other Bluetooth audio devices. By holding down the push button of the left earphone, it enters pairing mode. About the Bluetooth settings of the mobile device is the headphones as "BE Free8" to recognize. The connection is established without password entry. If you then switch on the right earphone via its control button, it automatically connects to the left earphone.


The connection technology between the earphones is NFMI (Near-Field Magnetic Induction), Advantages of this short-distance transmission technology are high energy efficiency and a low susceptibility to interference, with a simultaneously high transmission quality.

Im low end The BE Free8 presents a precise, if not very deep bass without dominating it. Of the midrange is colorful, but blurs lightly and sound details are minimally lost. in the treble shows the in-ear supple without distorting. The headphone handles well.

What affects the sound pleasure is the noise floor of the BE Free8. This occurs so strongly in appearance that an undisturbed music enjoyment with normal listening volume is hardly possible!

The integrated in the left earphone Microphone with CVC noise-canceling does not offer superior recording quality, but is suitable for making calls in comprehensible call quality.


Although the NuForce BE Free8 does not require a neckband or strap, the comfort is neat. Once you have found the matching ear pads, the in-ear sits pleasantly light in the ear. For a certain grip, the ergonomic housing, whereby the earphones can be inserted into the auricle. Disturbing outside noise is caused by the SpinFit earmolds first-class filtered.

First impression
Battery life

With the NuForce BE Free8 Optoma presents its first True Wireless in-ear headphones. In addition to a very good design implementation and a dynamic sound, which will appeal especially to ordinary music consumers, the BE Free8 also shows a serious weakness.

The above-average noise of the earphones reduces the enjoyment of music, at least for quiet titles and sequences. However, this is a subjective aspect. If you do not care about increased background noise and do not react to it "allergic", you get a decent True Wireless In-Ear with the NuForce BE Free8.
