Sound Quality

As their name implies, the 1MORE Dual Driver ANC Pro headphones are equipped with a pair of speaker drivers. Each earpiece has a 13.6-mm dynamic driver with a titanium composite diaphragm (a titanium layer is combined with a flexible PET layer), paired with a proprietary balanced armature. Balanced armatures are regularly used in hearing aids with the purpose of increasing sound clarity. To get a bit more technical, they use an electronic signal to vibrate a tiny reed that is balanced between two magnets inside a tiny enclosure. The motion of the reed is transferred to a very stiff aluminium diaphragm. In a hybrid setup, such as that of the 1MORE Dual Driver ANC Pro, where a balanced armature is combined with a dynamic driver, the balanced armature takes care of high frequencies. The specified frequency response of this dual driver setup is 20–40,000 Hz.


On the wireless side of things, 1MORE uses the Airoha Bluetooth 5.0 chip, which supports SBC, AAC (iOS devices), and LDAC Bluetooth audio codecs. In other words, the music you listen to will be wirelessly delivered to the 1MORE Dual Driver ANC Pro wireless headphones via either the SBC codec, universally supported by all Bluetooth devices, or the LDAC codec if your device supports it and you decide to turn it on. If you're using Tidal HiFi, Deezer HiFi, or Qobuz Hi-Fi subscriptions, they will be put to good use through the LDAC codec. Otherwise, you'll be perfectly fine using the SBC codec (320 kbps), or AAC codec, which is the only available option for iOS devices anyway.

In terms of sound quality, the 1MORE Dual Driver ANC Pro are a significant improvement over their predecessor, the Dual Driver BT ANC. The new and more expensive headphones are still lively and fun to listen to, but sound much more refined, neutral, and hi-fi-like. It's almost like they took the Dual Driver BT ANC and made them sound mature. Not a single part of the frequency spectrum is excessively emphasized or undercooked. Thanks to that, you get a seamless transition between the bass and mid-range, as well as the mid-range and high frequencies. There are a ton of details to be heard in the mid-range—both male and female vocals sound believable and have a nice presence, and it's easy to distinguish which instruments are playing. The vocals don't get drowned out by the bass, and the bass itself is quite deep and satisfyingly punchy, nor do the vocals get lost inside a more complex instrumental track. The highs could be a bit crispier and snappier, but at least they're not fatiguing. Overall, these headphones are a treat to listen to, and I would recommend them on sound quality alone even if they didn't come with a host of other excellent features.


As per usual, to get the most out of them, you need to spend a bit of time to find a pair of ear tips that fit your ears best. You want them to form a tight seal with your ear canal because that's the only way to get the best-possible bass response, but not so tight that they feel uncomfortable. I got that after switching from the factory-installed ear tips to 13-millimeter ones.

The passive noise isolation is mediocre. If you don't want to hear what's happening around you, you really do want to use the built-in ANC feature.

Active Noise Cancelling

The 1MORE Dual Driver ANC Pro wireless headphones are equipped with a hybrid active noise canceling technology. Active noise canceling is handled by a grand total of four microphones. Each earpiece has a feed-forward microphone built into the case, which is used to record environmental noise, and a secondary feed-back microphone, placed close to speaker drivers, where it records in-ear noise so that any remaining stray frequencies are filtered out.

The ANC feature has two levels. At Level 1, it cancels up to 35 dB of external noise, and that's the mode you'll want to use when flying, commuting, or wanting to block out as much noise as possible for any other reason. Level 2 reduces up to 20 dB of external noise. 1MORE describes Level 2 as "good for relaxing in cafes," but I have to admit I didn't find much use for it, in cafes or otherwise. When I wanted to use ANC, I used Level 1 to get the best-possible ANC performance. When I didn't want to actively cancel out the noise of my surroundings, I simply used the headphones as a regular pair of wireless in-ears, allowing them to block out the noise passively, buy hey, at least they're giving us two options, so no complaints here.


You can toggle through all available ANC levels (Level 1, Level 2, or off) by using the button on the left side of the neckband or the 1MORE Music mobile app. The app can also be used to turn on Wind Noise Reduction mode or update the firmware. There's also a "Smart burn-in" feature, which takes the headphones through a 12-hour process of playing various frequencies and white noises, or you can simply let them "burn-in" naturally through regular day-to-day sound reproduction.

ANC performance is very good, up there with what we saw (well, heard) from 1MORE's more recent products, such as the excellent True Wireless ANC headphones (reviewed here). As usual, deeper constant noises (think jet engines) get blocked out the most, while higher-pitched and oscillating ones, such as car horns, still reach your ears—there's no effective way to fight against those.

One aspect of the ANC implementation on the 1MORE Dual Driver ANC Pro is significantly better than on the 1MORE True Wireless ANC: the overall impact on sound quality. To be more precise, it is barely noticeable, to where most users won't be able to tell if ANC is on or off solely based on the sound performance of the 1MORE Dual Driver ANC Pro. At ANC Level 1, the bass becomes thicker and a bit sloppier, and a slight hint of boxiness and artificiality is added to the sound, but that's about it. At Level 2, there is even less of a difference to no ANC—the sound is somewhat louder, more in your face, with less air between instruments, which some users might even prefer as higher volume is often falsely perceived as better sound quality. One way or the other, this is a massive improvement for 1MORE, and one that came not too long after the release of the 1MORE True Wireless ANC, which disappointed me in this regard. Good stuff!
