High resolution in-ear headphones
Availability: In stock

Designed for music lovers and professionals, these High-Res certified earphones set a new standard for accuracy, speed and comfort.

Perfect for budding artists, home recording musicians and DJs, they offer incredible audio reproduction by combining the latest balanced armature driver technology with advanced crossover design. 

The HEM2 is part of the HEM series of in-ear headphones and has one Knowles™ balanced armature driver in each earbud. 

PC Magazine recently reviewed the HEM2:

"Optoma's NuForce lineup offers solid options for the serious music lover on a reasonable budget."

"The balance of the audio here is wonderful"

"The HEM2 delivers a clean, balanced audio experience, and ships with a wide assortment of accessories that puts many competing earphone models to shame."

The HEM series:

Hi-Res performance

The HEM series enables you to hear every track in exceptional clarity – for rich full-bodied sound. The combination of cutting-edge design and Hi-Res certified balanced armature driver technology results in balanced sound with crystal clear highs and explosive bass.

Crossover design

To achieve linear phase performance, the HEM series incorporate a three-way phase-coherent crossover design. The result is a natural, three-dimensional soundstage, lightning-fast transients and crystalline transparency.


Constructed with acoustically calculated, vibration-free Lexan™ earpieces the HEM series allow for prolonged listening without fatigueat any volume level. The in-ear monitors are lightweight making them ideal for use at home, in a recording studio, on stage or on the go.

Knowles™ balanced armature drivers

Featuring the latest generation of balanced armature drivers, the HEM series can reach frequencies as high as 40,000Hz - twice the frequency range of other balanced armature IEMs. Each HEM model houses either four (HEM8), three (HEM6), two (HEM4) or one (HEM2) Knowles™ balanced armature drivers in each earbud – designed to produce pure, authentic sound from a compact body. 

The more drivers, the more immersive the experience will be.

Pure sound, wherever you go

Two tangle-free cables are included so you can choose between a microphone and inline remote for convenience, and a high-end cable for the best possible performance. The high-end cable is made of OFC and silver, while the 2-pin cable connectors are a proprietary mix of silver and copper with separate ground return for each channel.

Superior comfort

For maximum comfort and performance they come with two types of ear tips in a range of sizes for a snug, slip-free fit. These include Comply™ soft memory foam ear tips which shape themselves to fit perfectly in the ear canal, offering superior isolation from noise and creating incredible bass response.
