Build Quality (4.5/5) – Overall construction is excellent. The cable is similar to the one on the old Trident model – a little rubbery but mostly soft and flexible. The housings are metal and feel very solid, boasting also a very nice finish. A single-button mic and remote – the first I’ve seen from Dunu – is located on the left-side cable
Isolation (3.5/5) – Very good for a dynamic-driver earphone
Microphonics (3.5/5) – Quite tolerable when worn cable-down; over-the-ear wear may be restricted by mic position
Comfort (3.5/5) – The housings are one the heavy side but rounded at the front for comfort. The fit is typical of a straight-barrel earphone
Sound (6.7/10) – The sound of the Detonator is decidedly explosive, underpinned by the enhanced bass response. The low end has good extension but also quite a lot of mid-bass emphasis, which gives the earphone a slightly boomy and bloated sound. Overall, the bass is a little too enhanced for my tastes, with more impact compared to Dunu’s popular Trident model as well as the VSonic GR02 Bass Edition.
The mids are warm and smooth – not as recessed as with the GR02 Bass Edition or RHA MA-350, but still not too prominent due to the bass emphasis. Clarity is similar to the Dunu Trident and lags behind the pricier DN-23 Landmine model. The earphones remain very smooth up into the treble and roll off at the top, giving up the energy – but also the potential for harshness and sibilance – of sets such as the GR02 Bass Edition.
Although the pricier DN-23 manages to be almost as bassy with less bloat, the bass of the DN-22M intrudes on the midrange at times. This causes the earphone to sound more congested than and less natural than the DN-23. Other than that, the presentation is quite good – a little wider compared to the Trident but otherwise similarly competent.
Value (8/10) – While the Dunu DN-22M Detonator is not quite an upgrade to the popular DN-12 Trident, it does offer a slightly bassier sound with better accessories. Plus, it boasts an inline microphone and remote – the first I’ve seen from Dunu – and retains the fantastic build quality Dunu has become known for. For those in search of a bulletproof entry-level smartphone headset, it’s a tough one to beat. Purely for audio quality, the less expensive DN-12 Trident is still my recommendation.
Pros: Fantastic build quality; well-accessorized
Cons: Not as accurate as the DN-12 Trident
