Optoma NuForce NE750M Earphones Review
      #47901 - 04/06/15 07:22 PM

The Optoma NuForce NE750M Earphones are one of the two new earbuds in the company's NuForce product line, the other one is the higher end NE800M. The Optoma NE750M offers a 8.6mm Titanium coated diaphragm driver with a powerful N45 Neodymium magnet, a tangle free and water-resistant cable with a built-in mic, and a sleek, comfortable-to-wear earbud design. The NE750M also features the company's Brilliance UWB (Ultra-wideband) driver technology that's designed to simulate a wide and open soundstage experience.


The look of the Optoma NuForce NE750M Earphones makes you want them. The black bullet-like chambers have a modern and clean style with red tip caps that are covered in a perfectly cut half-dome silicone buds. The aluminum chambers have that clean, machine-cut look and metal bands seat the audio cables to each of the chambers. The NE750M comes with 8 pairs of silicone earbuds in different sizes, and once you find the right size for your ears, you'll find the earphones very comfortable to wear. The all-weather cable has a layer of silicone-like coating that does two jobs: preventing tangles and providing water and sweat resistance. We tested the earphones while jogging in light rain and working out at the gym, and found that the cable with this coating was an ingenious design for these occasions. The 4.4-foot cable has a small control stick for taking and ending voice calls and play/pause music, and a built-in mic for voice calls. The cable also comes with a lapel clip which we found very useful during workout and for jogging.

Audio Quality

The Optoma NuForce NE750M employs metal for better sound quality, and that includes the aircraft grade aluminum enclosures for the two acoustic chambers, a titanium coated diaphragm, a N45 Neodymium magnet and a copper clad aluminum voice coil. The metal kit gives the earphones the rigid body to reduce micro-dynamic vibrations that might distort the reproduction of music tracks. The NE750M has 16 Ohms impedance, the frequency response is 20Hz - 20kHz and its max input sound level is 120dB SPL. The earphones also employ the proprietary Brilliance driver technology that's a-periodic loading to give the earphones a "large open-back headphones' design and reduces inner ear pressure for long period of wearing comfort.

So the sleek look, check. The comfortable form, check. The high level material and unique technology, check. How's the sound quality? For a $99 pair, the Optoma NuForce NE750M sounds tinny compared to the similarly priced V-MODA Vibe/Revamp and the cheaper Moshi Vortex. We tested it with a variety of music genres including classical (Mozart and Tchaikovsky), acoustic guitar (Martin Simpson), rock and pop (many artists) as well as synthesized dance and workout music. In our tests, the NE750M offered good sound clarity and channel balance. Each instrument and each vocal stood on its own and showed no muddying of any kind. Though the driver has a decent size, the volume in our tests was lower than the V-MODA and the Moshi, but NE750M didn't blow out or distort when we turned the volume to very high. The tinny sounding unfortunately plagued all frequencies, and as a result, the vocals sounded thin, the mids sounded edgy and the bass lacked pumping force. For example, cello didn't have its signature bellow and bass drums didn't have the thumping reproduction. The tinny sound didn't bode well especially in heavily synthesized dance and workout tracks, giving out almost grading quality in the highs.


We seriously wanted to love the NE750M because it offers the cool look and all the features of comfort and water resistance for all-weather and workout scenarios. But the sound quality lacks full dynamic and sounds tinny in almost every music genre. It would've been a decent pair of replaceable earbuds but the price puts the NE750M in a more elite earbuds company that offers better audio quality and more superb and well-rounded sound. The NE800M is supposed to have improved bass and fuller sound that's also $100 more than the NE750M. For movie watching, voice calls and some gaming on your phone, the NE750M would work much better for you than music playback.

Editor's Ratings (1-5): 3.5
What's Hot: Attractive looking, good material and nicely machined, all-weather build.
What's Not: Sounds tinny in music playback.
