1MORE ComfoBuds Mini

| TWS | Dynamic Driver |

1MORE ComfoBuds Mini, the world’s smallest true wireless headphones that include Active Noise Cancelling technology.

The 1MORE ComfoBuds Mini are one of the newest TWS from the brand, joining their newest generation of earphones, like the 1MORE PistonBuds Pro and the 1MORE EVO.

Nonetheless, the ComofoBuds Mini have a different approach than the 2 aforementioned headphones, with the Mini model aiming to reduce size, weight and perfecting fit and comfort.

The 1MORE ComfoBuds Mini are equipped with a 7mm single dynamic driver per earpiece, that sports a dual magnetic design and graphene drivers – and a mere 3.7g of weight.

Despite the tiny size, this model comes packed with ANC (active noise cancelling), an IPX5 waterproof rating, Qi wireless charging and fast charging – 10 minutes of fast charge can provide 1.5 hours of playback.

In addition to this, the ComfoBuds Mini come with 30 soothing sounds and SoundID sound customization.

The internal soothing sounds is a feature that was somewhat seen on the older 1MORE ComfoBuds Z; this is a specific function that allows the TWS to be used as a relaxing device with sounds like rain, sea, forest, etc and a settable auto-off timer – though it requires to be used via the 1MORE app.

The 1MORE ComfoBuds Mini can be also found as 1MORE ES603 and is available is both Obsidian black or Mica white color.

Bass & Sub Bass

Technically, bass on the 1MORE ComfoBuds Mini have a tight and clean bass response but for average users this could translate into a less bassy sound.

Consequently, bass thirsty listeners will find this TWS to be a bit conservative on the mid bass range with decent punchiness and too shy on the sub-bass deepness and reach.

On the other hand and despite having a different initial public marketed, the 1MORE ComfoBuds Mini have a more refined and clean sound on the lower frequencies, that is usually seek and found on audio-enthusiasts and audiophile headphones.

With an EQ, some extra punchiness and fullness can be squeezed out of the ComfoBuds Mini but sub-bass will be just slightly deeper.

When activating the Active modes of this TWS, there is a total makeover of it’s sound profile, with a bassy, punchy and loose response that can also respond with a noticeably deeper sound.

Mids & Vocals

The 1MORE ComfoBuds Mini have a nicely tuned midrange without the need of an EQ.

Right out of the box, mids and vocals present a gentle and cozy sound but without suffering from typical issues of non-forward sounding earphones.

Lower mids will offer a sufficient fullness while male vocals will exhibit an inviting but not distant nor laid back sound.

Upper mids and female vocals, do sound a bit more forwardy than their lower mids but we will not rate them as a forward nor harsh sound.

Instead, female vocals will benefit from a lively and very clear presence while the overall feel of the upper midrange will become crisp with marginally and very tolerable harshness on extremely sharp notes.

In addition to this, the 1MORE ComfoBuds Mini share a tendency seen on the 1MORE PistonBuds Pro with a less boosted and more flat midrange tuning than most commercial headphones.

When activating the Active modes of this TWS, the flat and clean mids will transform in a busier and more congested response but with a much fuller a warmer sound.



Highs & Treble

Despite the small size and single driver configuration, this TWS has a much brighter and clear sound than other budget TWS.

The highs and treble of the ComfoBuds Mini will provide brightness and a bit of detail for more demanding listeners but it is fair to note that it might become more fatiguing at times.

Additionally, the overall sound of this TWS balances pretty well whenever tracks and genres are not too centered on the treble ranges.

Despite exhibiting some piercing peaks on very sharp notes, sibilance had a low incidence and was rarely noticed.

Sound Isolation

Despite the tiny size, the 1MORE ComfoBuds Mini include Active Noise Cancelling with 4 modes: ANC Strong (promising up to -40dB), ANC Mild, Wind Noise Resistance (mode dedicated to cancel noise generated by wind) and, finally, Pass-Through mode (mode that enhances the awareness of the surrounding noises)

Throughout our measuring and testing, the ComfoBuds Mini had poor passive isolation but it got massively and exponentially stronger when activating its ANC mode.

Our noise cancelling measurement saw a maximum peak of 30dB of noise cancellation on its summit and a lowest dip of 15dB – on par with the modern performance average of efficient models and quite remarkable for such a small earphone.

Moreover, the Passthrough mode showed a clear improvement of the awareness of the environment while still allowing a pleasant music listening experience.

Response to Equalization

Differently than most TWS on the market, the 1MORE ComfoBuds Mini have SoundID incorporated in the device.

This allows an easier EQ handling and customization to a vaster public, which showed significant sound quality and character modification with a simple tap on 1MORE app.

Moreover, the very flat midrange and well-distributed sound signature allows an excellent space for fine tuning or complete retuning by equalizing.
