Optoma NuForce HEM Dynamic Test Review

NuForce HEM Dynamic Review - Hi-Res in-ear headphones

Updated by Timo Altmeyer on February 16, 2022

The Optoma NuForce HEM Dynamic is the new entry-level model of the NuForce HEM series, which uses a NuForce HEM2. Unlike the other models in the series, the HEM Dynamic does not use Balanced Armature drivers, but uses dynamic drivers instead. In the test lasting several weeks, I took a closer look at the in-ear.

First impression of the NuForce HEM Dynamic

What's in the box

The NuForce HEM series in particular is known for offering a considerable scope of delivery. As an entry-level model, however, the scope of delivery of the NuForce HEM Dynamic is a bit narrower. The in-ear is delivered including a cable with cable remote control and microphone, a case, 3 pairs of silicone ear tips in sizes S, M and L, 2 pairs of Comply pads T-100 in M ​​and L, a cable clip and one Operation manual . Measured against the price of the in-ear, the scope of delivery is not objectionable.

Design and workmanship

A common feature of all NuForce HEM in-ears is the typical teardrop shape. Ergonomically shaped, the HEM Dynamic can be precisely inserted into the auricle. The plastic housing consists of two assembled parts with a matt and a transparent side that allows a view inside. The matt part is adorned with a "HEM Dynamic" print. In addition, both earphones are provided with a left-right mark. The weight of one unit is only 3g. The processing quality is nothing to complain about. The in-ear is available in the colors "Crystal White" and "Charcoal Black".

The earphones and the cord can be separated from each other. One advantage of this is that in the event of a cable break, the entire in-ear does not become unusable. Replacement cables can be purchased directly from the manufacturer's shop page. The connection is made via a 2-pin plug connection. The cable supplied is 1.38 meters long and has a one-button wired remote control and microphone in the upper third. The quality of workmanship of the cable cannot be criticized. The plug connections and the rubber sheathing of the cable leave a robust impression.

sound quality

The Optoma NuForce HEM Dynamic also takes a different approach in terms of sound. Instead of a linear frequency response and thus a more neutral tuning, the in-ear delivers a clearly pronounced low-frequency range.

Conventional music lovers in particular will like the extremely dynamic sound of the HEM Dynamic. The in-ear is suitable for a wide range of different styles of music. Bass-emphasized music is played powerfully and gives you a real feeling of being right in the middle of it all. But also quiet songs, where precision and tonal details are important, come into their own. The earphones have the powerful bass range well under control without appearing boomy and unclean. The in-ear could only use a little more thrust in the depth. 

The reproduction in the middle is warm in color. The distinction between the bass and the middle succeeds without overlapping. Vocals come out very warm. Above all, the treble reproduction is subtle, yet rich in detail and by no means too sharp. The dynamic driver largely utilizes the frequency range from 20 Hz to 40 kHz specified by Optoma. The NuForce HEM Dynamic can be described in one sentence as a dynamic in-ear, without paying too much attention to precision, but rather taking the music lover through its lively sound.

Wired remote control and microphone

In the upper third of the supplied audio cable there is a one-button wired remote control and microphone. With the cable remote control it is possible to control the music playback and to take calls. The control of the music playback refers only to a play and pause function and the skipping of tracks. Volume control is not possible. The recording quality of the microphone is not objectionable. Discussions can easily be conducted about it.


Due to the ergonomic teardrop shape of the NuForce HEM Dynamic, it is optimally adapted to the auricle and can literally be inserted into the ear. The cable is placed over the ear. The best possible and barely noticeable fit is ensured. At the same time, excellent noise isolation is achieved, which can hardly be topped in conjunction with the included Comply ear pads. Thanks to the low weight of only 3g per unit, nothing stands in the way of a longer session. Disturbing cable noises do not occur due to the rubberized audio cable.

Optoma NuForce HEM Dynamic Test Review

Optoma NuForce HEM Dynamic


Ergonomic design
Good workmanship
Removable cable
Dynamic sound
Powerful sound
Pleasant wearing comfort


Cable remote control without volume control
Slightly weakening draft


The NuForce HEM Dynamic is mainly due to its design and the good build quality of the NuForce HEM model series. In terms of sound, however, the in-ear takes a completely different approach and delivers a predominantly deep, dynamic sound that is far removed from the neutral-analytical sound of the other HEM models. Especially the normal music lover will enjoy the lively sound of the HEM Dynamic. You have to do without the extensive scope of delivery of the other HEM models. Nevertheless, the scope of delivery can be seen and will do justice to the budget price of the In-Ears. All in all, the NuForce HEM Dynamic is a good-sounding in-ear in the usual good Optoma processing quality with a tonal focus on a rousing musical enjoyment.
