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.
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.
The connection between player and the left (main) earphone is through Bluetooth 4.1 guaranteed. The connection range is about 10 meters.
Through the support of the aptX LL Codec is a delay-free Bluetooth connection with higher data rate (up to 352 kbps) possible, whereby the transmission quality is further improved. However, this requires an aptX compatible mobile device.
The earphones are equipped with one each 5.8mm large, dynamic driver. It frequency range gives Optoma 20 Hz to 20 kHz at. The impedance is 32 Ohm. sensitivity is 92dB +/- 3dB (1 kHz).
The BE Free8 is an in-ear headphone with V-shaped sound signature, Striking features are the highlighted bass and treble, as well as the more moderate midrange. By the particular dynamic, warm sound The in-ear is especially suitable for pop, modern rock and EDM.
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!
Operation and microphone
The Music playback and answering is controlled by the control button on the left earphone. Songs can be paused (press 1x) and skip (press 2x). A volume control is not possible. Incoming calls can be accepted or rejected at the touch of a button, as well as voice assistants such as Google's Assistant or Apple's Siri can be started by pressing the button.
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.
However, the BE Free8 is less suitable for sports activities. Especially with fast head movements, the earphones can slip or even fall out.
Optoma does not specify the battery capacity. The achieved in the test Battery life was average for medium playback volume on average 3 ½ hours, If the headset reaches a low battery level, you will be notified by a repeated beep. The earphones are charged via the Ladeetui, This is also equipped with a battery and allows the earphones to charge three times. For charging, the earphones are inserted into the perfectly fitting shell of the case and magnetically fixed.
