Foreword: NuForce BE6i

Ever since Apple turned its back on the classic jack, other mobile device manufacturers have followed the trend. A solution to the problem are adapters, which still allow headphones and mobile devices to connect. An alternative to this are again wireless bluetooth headphone or earphone. The NuForce BE6i from Optoma is such a Bluetooth earphone, which is also a Further development of the predecessor model "NuForce BE6" is. The main differences are an extended battery life as well as dust and water protection according to IPX5 protection.

NuForce BE6i test

Design, workmanship and delivery

The design in-ear headphone is smart and is aimed primarily at the mobile and athletic users. Unlike other Bluetooth IEMs, such as the Apple AirPods, the earphone is connected to a ribbon cable. In the upper third of the right sound unit is a 3 button wired remote control including microphone and Micro USB socket for charging the earphone. The orchestras consist of Aluminium and are comparatively large. No wonder, because in both units a lot of hardware, including the battery, housed! After Degree of protection IPX5 is the in-ear from dust and "Jet water from any angle" protected. Rain or other liquids are not a problem for the NuForce BE6i. The ends of the body are magnetic, so the earphone can easily be worn around the neck when not in use. The engraved "NU" logo sets accents. The direction of wear is clearly marked L and R on both units.

The quality of workmanship of the NuForce BE6i is only partially acceptable. Above all, the processing of the sounding body was convincing. In turn, the processing quality of the wired remote control was not convincing. This is completely made of plastic and looks cheap assembled overall. In addition, the keys do not have a particularly good pressure point.

What's in the box

The What's in the box Optoma NuForce is typically very lush. In addition to the earphones, there are four pairs of silicone earpads in the sizes XS, S, M and L, two pairs Comply ear pads M and L, consisting of memory foam, a pair of ear wings, a cable clip, a carrying case, a charging cable and of course a manual.


The commissioning of the BE6i is uncomplicated and can also be carried out by the technical layman without any problems. If you press the power button for 6 seconds, you get to the Pairing mode, To connect to a mobile device, just select the Optoma NuForce BE6i Bluetooth device settings on your mobile device. The connection is established without password entry. A voice message communicates the successful connection. Each time it is turned on, it automatically connects to the mobile device unless you remove the pairing.

sound quality

Equipped is the NuForce BE6i with one each 10 mm large dynamic driver. It frequency range gives Optoma 20 Hz to 20 kHz at. The impedance is 20 Ohm. sensitivity is 95dB +/- 3dB (1 kHz).

The NuForce BE6i presents as Bluetooth earphones with (moderate) U-sound curve, As a result, the earphone is (still) based on the conventional consumer, but also reveals significant hi-fi tendencies. Of the low end is only slightly raised, but still noticeable. The bass reproduction is precise and anything but intrusive. Powerful and particularly rich basses are guaranteed to be missed by bass lovers! Good is the middle playback. In the middle sound particularly grippy with a touch of color. Of the height range, especially the upper heights, are also slightly raised. Describing the treble playback can be supple, without distorting in any way by sharp sibilants.

The presentation of details is not necessarily a strength of Bluetooth headphones. Many headphones of this type tend to sound muddy. The NuForce BE6i on the other hand convinces with a very special clear and above all noise-free music reproduction with a comparatively high level of detail. Through the support of the aptX codec A more stable Bluetooth connection with higher data rates (up to 352 kbps) is possible, which further improves the sound quality. However, this requires an aptX compatible mobile device.


The Bluetooth Standard amounts to version 4.1 with EDR (Enhanced Data Rate), The following Bluetooth profiles are supported: HSP 1.2, HFP 1.6, A2DP 1.2, AVRCP 1.4, APT-X, AAC. The earphone can remember connection data from a maximum of 8 different devices.

The Bluetooth connection quality and connection range are very good. Optoma gives the maximum Transmission Distance with 30 meters on. The tested, lossless range was included about 20 meters, Only from this range it came to isolated dropouts.

Wired remote control and microphone

As already mentioned, the cable remote unfortunately does not win a prize. The quality of workmanship does not match the rest of the earphones, especially the high-quality aluminum bodies. Among other things, it is possible to control the music playback via the remote control. Overall there is 3 control buttons, The earphone can be switched on via the middle button. But as a multifunctional control button, songs can be paused and resumed, as well as receiving, ending and rejecting incoming calls. The other two buttons are used for Volume Control, In addition, songs can be skipped by holding down for a longer time.

Other features of the wired remote control are one Status LED, One Micro-USB charging socket and how to make a Microphone. Recording quality of the microphone is good and is enough to make phone calls about it.


The sound of the NuForce BE6i is comparatively heavy and big. The weight of the earphone is a total of 19g. When wearing the In-Ears, the rather long cases protrude far out of the ear, which, in combination with the high weight, causes the earphone to fall down. Readjustment was not uncommon during the test hearing! An advantage is the couple ear wingsthat Optoma ships with. The ear wings significantly improve wearing comfort and supportso that the BE6i can also be easily worn for sports.

NuForce BE6i wired remote control


The casings of the earphone each contain a cylindrical 80 mAh Lithium-ion battery, The measured total capacity is 135 mAh. The runtime measured at medium volume is 7 hours. The deviation at higher or lower volume is approximately + 1 / -1 hours. By pressing all control buttons of the wired remote control, you will be informed by voice prompt and LED indicator on the current battery level.

Charged is the earphone after 2 hours. As shown in the test, the earphone can not charge with any charger. The NuForce BE6i can not cope with the fast-charging devices that are included in most smartphones today. Charging on the PC or with an 5V 1A charger worked without any problems.

First impression
Battery life

The Optoma NuForce BE6i is a very good sounding Bluetooth IEM, which pleases by its moderate U-sound curve sound rather the demanding music listener, than the conventional consumer. The sound convinces with a precise bass, a colored midrange and smooth highs. The level of detail and clarity are comparatively good for a Bluetooth earpiece.

There are point deductions for the poorly implemented wired remote control and the somewhat getting used to wearing comfort, which can be significantly improved by the included ear wings.
