Redesigned and improved comfort

To further refine the Comfobuds' superior sound and comfort, 1more sought a design that would fit ears of all shapes and sizes.


The design of the Comfobuds Pro features a beautiful streamlined form inspired by dripping liquid metal. The Comfobuds Pro is designed with a sleek, streamlined shape inspired by dripping liquid metal and is adjusted to fit at the proper insertion angle for a comfortable, pressure-free fit.


1more has always led the way in advanced design, and the Comfobuds Pro delivers a new era of style that combines elegance and comfort.


Powerful drivers & studio-tuned sound

Comfobuds Pro is equipped with 13.4mm drivers, which is large for a completely wireless earphone. This allows it to deliver clear sound across the entire frequency range.


In addition, Grammy award-winning sound engineer Luca Bignardi tuned them to deliver a perfectly balanced and accurate soundstage that takes advantage of the performance of these large drivers.


Comfobuds Pro's sound design leads the price range.


Six microphones for accurate and effective active noise cancellation

1more has equipped the Comfobuds Pro with a total of four feed-forward and feedback ANC microphones, one on each side, controlled by precise algorithms. These microphones work together functionally and work seamlessly to suppress both ambient and in-ear noise.


1more claims that the nominal depth of active noise cancellation achieved by these four microphones has reached 40dB.


Meanwhile, the call microphone properly detects and amplifies the user's voice, ensuring that the caller's voice reaches the other party clearly even in the noisiest of environments.


Enough playback time to cover a full day

The 1more Comfobuds Pro offers a long playback time, so you can always enjoy your music without worrying about the battery running low.


Don't worry if the battery runs out. It supports fast charging technology, so you can get 2 hours of listening time after just 15 minutes of charging.



The 1more package comes in a uniform design. Its design is a bit luxurious for its price range.


1more's packaging features a design drawing of the earphones, which is an indication that 1more cares about the design every time, is confident in it, and wants users to enjoy the design.


There is a lot of information about the designer's concept of the earphones, and you can feel the brand's love for the earphones.


Accessories include a replacement earpiece, a USB cable (Type-C) for charging, stickers, and a manual.


The QR code also allows you to check if the product is genuine or not.

Build quality

The build quality meets the standard for the price.


The lid doesn't wobble, and the magnets that hold the lid in place work well, so it's unlikely that the lid will open and the earphones will pop out unless it's shaken too hard.


The case is compact, sleek, and easy to slip into a pocket for easy carrying.

Even with the included ear tips, the fit is not bad. However, in my case, the included eartips don't seem to provide a good enough seal to take full advantage of the ANC performance.

In my case, I felt the AZLA SednaEarfit Short improved the effectiveness of noise cancellation. This eartip can fit in the case in size L.

Connection quality

Tested with AAC connected to Cayin N6II / E02. Excellent connection quality in the price range. I don't know because I haven't been to the crowd because of COVID-19, but it is stable at home. The distance resistance is excellent, and it is seamless and connected as it is even at a distance of about 5 m. Communication was interrupted for a moment when a shield was sandwiched, but the connection was maintained and music playback continued immediately. There was no interruption after that.


There may be a small amount of white noise, but it probably doesn't bother most people.


ANC & Hear-through Performance

Hear-through performance

Even with the hear-through turned on, the white noise does not seem to increase much, and it seems to be rather accurate. During hear-through, ambient sounds are generally natural, and I can hear my own voice quite naturally.


ANC performance

It's not outstanding in its price range, but it seems to increase sound insulation widely and evenly, and the audible effect is quite noticeable. As you can hear when you listen to the sound source, this model clearly changes the way you hear when you turn on the ANC, so it is not difficult to feel the effect before and after turning on/off the ANC.


Sound quality

The 1more Comfobuds Pro has a studio-tuned flat sound that approximates the Harman target curve. The bass depth and highs are a bit restrained, and the extension seems a bit lacking to me, but the midrange is well defined, the textures are close to natural, and the sound image of each note is fairly uniform and well balanced. It can almost completely satisfy audiophiles who are looking for a good quality flat sound, and would be pretty close to ideal as an "audiophile TWS".

Sound quality general comment
  • Original sound fidelity: A
  • Recommendation: A+
  • Personal preference: S


For the genuine audiophile who wants to carry around the studio monitor-like sound of Harman tuning, the 1more Comfobuds Pro is a completely wireless earphone that is pretty close to ideal.


The excellent sound quality, which is quite balanced from a purely audio standpoint, will be welcomed by audiophiles as one of the dominant earphones in this price range.


Personally, I'm a little frustrated with the expandability, but it's a great model that offers near-perfect sound.

General comment

The 1more Comfobuds Pro is a completely wireless earphone for audiophiles that is relatively faithful to the established studio tuning style of the Harman Target. The sound quality tends to be a bit lacking in the low frequency range and a bit lacking in expandability, but it provides a very good neutral sound.


The ANC is not powerful, but the accuracy is not bad, and it seems to block out noise while retaining the environmental sounds necessary for daily life. The included app allows you to customize the controls and make them your own.
