Optoma was founded after that wild Y2K scare and originally focused on optical projectors, but the real magic happened almost a decade and a half later when Optoma and NuForce integrated to focus on audio-visual entertainment. Fast forward to 2017, and the partnership has produced the BE Free8: a functional, pleasing set of truly wireless earbuds that offer subwoofer-like bass from units the size of Yahtzee die.

But are they worth the $149 asking price? Let’s dig deeper.

What’s inside

Charging/carrying case, earbuds, micro USB charging cable and SpinFit silicone ear tips.

The NuForce BE Free8 includes the two wireless earbuds, an extra pair of ear gels, a charging cable and the carrying case which doubles as a charging dock. The packaging is simple and no-fuss. This is excellent, considering I hate fumbling around with twist ties; it makes me feel like I’ve lost all motor-skill function.

Build & Design

The plastic housing and angled ear tips provide maximum comfort.

The housing of the earbuds and case is entirely plastic, making it durable, lightweight, and cost-effective. I roughed the case up while the earbuds rested inside and have yet to see a single mark on the outside, which appears to be dressed in a protective coating. The case’s lid is magnetized, ridding the user of any worries that it may inadvertently pop open in a bag.

Modestly finished, the earbuds themselves are a shiny plastic with diagonally embossed lines racing down the veneer. These lines allow for a white LED indicator to shine through when the buds are activated through pause, play, skipping a track, etc. There’s only one button to be found on each earbud, and that powers each earbud on in the pre-production unit (the final model allows for synchronized powering on/off of the earbuds.)

Slightly angled for maximum comfort, the earbuds rest snugly in the ear without causing any pain or irritation. The included sleeves work wonderfully with this angled design, and create a gentle seal to block out most ambient noise; allowing for optimal sound quality. The earbuds balance nicely while evenly distributing their weight across the ear canal, concha, and antitragus, making these the most comfortable Bluetooth earbuds I’ve used to date—even if they stick out a bit for my liking.


I could always rely on a swift connection when pairing with my phone. Keeping that connection, though, was another story.

It should be reiterated here that my model of the BE Free8 is a pre-production unit. Feel free to take my opinion on the connectivity with a grain of salt.

I must say though, the BE Free8 connected immediately with my LG G6, iPad and 2012 Macbook Pro; an antique by today’s standards. Unfortunately, the Bluetooth and NFMI technology—in this pre-production unit, anyway—had trouble maintaining a reliable connection. They also had a static-y background noise that constantly underscored my media playback. Often, the song I was listening to would go out for a second or two before coming back. It wasn’t too annoying since it only happened a few times a day; and I listened to these all day at work.

According to people I was talking with, the mic was just fine. It sounded a little muffled to me, but that’s likely a result of the placement on the left earbud. The microphone will suffice for general calls and video chats though. On my end, the other person came in exceptionally clear because of the BE Free8’s ability to passively block out ambient noise.


The charging case help give the BE Free8 an extra boost to keep my ears entertained all day long.

The battery life had the stamina of a marathon runner. Truly! It lasted the reported time of 4 hours and the charging case added an extra 12 hours of battery life. Moreover, the BE Free8 enables battery display on your phone’s notification bar, so listeners can time their anxious hunt for the charging case appropriately.

Though said charging case is reminiscent of the alien pod that landed to communicate with Amy Adams in The Arrival,  fortunately for us: the similarities end there. I applaud the nifty and understated design of the charging case. Adorned with a total of five LEDs, it’s informative and minimal. The top two lights are informed directly by the earbuds. If both are holstered, both lights activate, and if only one is holstered: well, then only one earbud is docked. The other is likely with all of your or your girlfriend’s bobby pins, never to be found again. The three LEDs located at the bottom correspond with the number of full charges are left in the charging case (one LED represents one hour of battery life).

The only downside to the charging case is that it’s fingerprint-prone—not an issue for me but may be for those diehard aesthetes—and a bit slippery. However, the inside panel has rubberized grippies (technical term, I know) to keep the buds stable when you remove them, another understated, appreciated feature.

Sound Quality

Despite a small profile, the design work that went into the BE Free8 is evident.

The BE Free8’s overall signature was definitely “V” shaped: definitively emphasized bass and boosted highs steal the show away from comparatively forsaken mids. While that’s quite common with headphones, that has a couple notable consequences. Namely, the illusion of realism can be a bit lacking, and instrumental separation isn’t quite there due to the muddled, befuddled mid range.  

NuForce knows how to handle bass! After having been disappointed by the LG Tone Free and Studio bass reproduction, I can happily report that the BE Free8 handles bass exceptionally well. I was particularly impressed with how It’s Strange by Louis the Child sounded while knowing that it was being driven by such a compact device (relatively speaking; they’re large for Bluetooth earbuds). Although I’m using It’s Strange to address my bass-response impressions, I’d like to point out that I was impressed by the BE Free8’s range throughout the entire song, making it an absolute pleasure to listen to.

Okay, alright; you’re right. Enough gushing. Bass is the conductor of most of Louis the Child’s music and it had a clean response that doesn’t bleed into the mids. 

Mediocre mids. The best thing about them is that they allow for fun alliteration, I suppose. It’s apparent that they aren’t the highlight of these earbuds, since they feel a bit distant at times and lack the dynamic response given to the bass. This is particularly apparent in She Said by Sundara Karma. Generally speaking: I love the vocals in this song—however, the BE Free8’s mid underemphasis cut the resonant depth of Oscar Lulu a bit short. His voice ends up sounding a bit hollow.

Furthermore, Lulu and Ally Batty’s guitar riffs came off a bit muffled, and unclear. It reminded me of pouring too much milk into the cereal bowl. I can’t eat it quickly enough, leaving me with mushy, unsatisfying cheerios. Yeah, the mids are kind of like that… but a much less critical part of a balanced breakfast.

The piano in Twenty One Pilot’s Pantaloon is a good test for these earbuds. The hi-end of the scale is pronounced, but without any sibilance issues—while the reproduction of the hi-hat hits present for the majority of the song is up-front, they don’t overpower other notes. The strikes came off neat and controlled, without being overly boosted to the point of eardrum pain. This is an issue that I’ve come across with a few headphone brands, and I’m relieved to see that NuForce didn’t go this route when engineering the higher frequency response.


The earbuds do protrude a bit, but their ergonomic design mitigates much of the ear fatigue.

Despite a few hiccups related to having a pre-production unit, the Optoma NuForce BE Free8 was a very rewarding Bluetooth experience. I’m still in shock by its bass response but aptX low latency tech really did provide a massive step-up in performance from older Bluetooth devices. It’s also nice to know that you can use these without any lag or delay with a new TV that supports the codec.

The design and features of these were outstanding. I can’t recommend these enough. The only problem that some consumers may come across is with the physical design, and while it may be a bit plain for some—I call it refined.
