The 1More Sonoflow headphones are made of plastic and pleather, but they have a sleek and well-built appearance that is comparable to more expensive headphones from Bose or Sony. To truly tell the difference between them, you would need to have them side-by-side.

The headphones are soft and comfortable to wear, with a neutral and classic design. They are lightweight and not waterproof. The first thing you will notice about the headphones is how soft the earcups and headband are, thanks to their thick memory foam padding and supple protein leather cover.

  • The earcups are made of soft, protein leather that is gentle on the skin.
  • The headband is also made of soft, memory foam that provides a comfortable fit.
  • The headphones are lightweight and weigh just 250g.
  • The headphones are not waterproof, so they should not be used in wet or humid conditions.
  • The headphones have a neutral and classic design that will look good with any outfit.

The headphones are all black, except for a red cloth lining inside each earcup. The L and R labels on the earcups help you match them to your left and right ears. These labels are also important when using the gray zip-up protective case that comes with the Sonoflow. The inside of the case has depressions for each earcup, with L and R embossed in the proper slots. When you line up the L and R on the earcups with the L and R on the case, the headphones fit snugly inside the case, which will protect them during transport. There is also a net pocket for the included USB-C to USB-A charging cable and the 3.5mm audio cable that allows you to use the Sonoflow as a wired headphone.

The controls on the SonoFlow headphones are physical buttons, which is not necessarily a bad thing. However, the buttons are very clicky and not very tactile, making them difficult to find and use. The left earcup has a USB-C port, while the right earcup has an on/off button, volume and playback controls, an ANC switch, and a 3.5mm jack for wired listening.

Over-ear headphones rarely have an IP rating, and the SonoFlow headphones are no exception. This means that they should not be used in wet or humid conditions, such as the gym or in heavy rain. The headphones are comfortable to wear for extended periods of time, and they have a good seal that blocks out ambient noise. The sound quality is excellent, with clear highs and deep bass. The noise cancellation is also very effective, and it can block out most background noise.

1More promises 70 hours of playback with active noise cancellation (ANC) turned off, and 50 hours with ANC on after a full 80-minute charge. You can get a full 5 hours of playback from a 5-minute charge. The excellent new Soundcore Space Q45, which costs £30 more, is a good comparison. The Sonoflow’s build quality is just as nice, and its case is far superior to the Q45’s, which inexplicably comes with a cheap plastic insert for positioning the headphones in the case.

The 1More Sonoflow headphones are equipped with 40mm dynamic drivers that produce a wide frequency range of 20Hz to 20kHz. This means that they can reproduce a wide range of sounds, from deep bass to high-pitched treble. The headphones also support the AAC, LDAC, and SBC codecs, which are different ways of transmitting audio over Bluetooth. LDAC is the highest quality codec, and it can provide a more detailed and immersive listening experience.

Audio Capabilities

  • 40mm dynamic drivers: These drivers are large and powerful, and they can produce a wide range of sounds. They are also very efficient, which means that they can produce a lot of sound without using a lot of power.
  • Frequency range of 20Hz to 20kHz: This means that the headphones can reproduce sounds from very low bass to very high treble. This is important for getting a balanced and natural sound.
  • Support for AAC, LDAC, and SBC codecs: These codecs are different ways of transmitting audio over Bluetooth. LDAC is the highest quality codec, and it can provide a more detailed and immersive listening experience.

The 1More Sonoflow headphones do not support the aptX codec, which is a common higher-quality streaming codec that is supported by Android devices but not Apple’s iOS. LDAC is a Sony-developed codec that is challenging Qualcomm’s aptX domination. It offers higher-resolution streaming than standard aptX.

Older Android phones might not support LDAC, but if you’ve bought a high-quality Android device in the last three years or so, odds are good that it supports both aptX and LDAC.
If you are looking for the best possible audio quality when streaming music over Bluetooth, you should choose headphones that support LDAC. However, if you are on a budget or if your device does not support LDAC, aptX is a good option

1More has an app for both iOS and Android. Once you have paired the Sonoflow headphones to your phone and connected it to the app, you will see an app screen that shows the current battery level, and controls that let you choose between ANC, pass-through, and off. There is a switch to turn on the high-definition codec if you are streaming high-def audio.

There is also a “Soothing Sounds” selection of 29 ambient noise options, including:
• Summer rain
• Medium fire
• Drizzle
• Thunderstorm
• Breeze
• Spring water
• Bamboo forest wind
• Snowing
• Underwater
• Outer space
• Gale
• Field
• Forest
• Waterfall
• River
• Ocean swell
• Tiny waves
• Desert
• Medium waves
• Mountain summit
• Volcano
• Jet stream
• Creek
• Flow
• Stream
• Train
• Creek
• Storm
• Downpour

These are synthesized instead of real field recordings, but they do a good job of blocking out the outside world.
The app is well-designed and easy to use. It is a great way to customize the sound of your headphones and to get the most out of them. The Sound Options panel gives you access to a dozen EQ presets, including: Default Bass booster Classical Deep Hip-hop Pop Bass reducers Acoustic Podcast Electronic Lounge Vocal booster You can also create your own custom equalization and save it for future use. The EQ presets are a great way to quickly and easily change the sound of your headphones. If you’re not sure what settings you want, you can start with the default preset and then adjust the settings to your liking. The custom equalization is a great way to create a sound that’s perfect for your ears. You can adjust the settings to emphasize the frequencies that you like and to reduce the frequencies that you don’t like. The Sound Options panel is a powerful tool that can help you get the most out of your headphones.

In Use:-

Connection & Stability:

1More has a long history of producing high-quality products with excellent signal stability. The Sonoflow headphones are no exception. They offer a stable signal even when using the LDAC codec at 900+ kbps. This is impressive, as LDAC is a high-quality codec that can require more bandwidth than other codecs.

Battery Life:

The Sonoflow headphones offer a battery life of up to 40 hours when using the LDAC codec and ANC. This is a good battery life, but it is not as good as the battery life that you can get when using other codecs, such as AAC. If you are an Apple user, you are likely to get a better battery life when using AAC.

ANC with QuietMax Technology

The Sonoflow headphones offer good passive isolation thanks to their memory foam ear cushions. They also come with QuietMax ANC technology, which is a proprietary noise cancellation technology developed by 1More. QuietMax ANC is effective at reducing a wide range of ambient noise, including traffic noise, wind noise, and the noise of a fan. In our tests, QuietMax ANC was able to reduce the noise of our full-tower desktop PC by about 35 dB. This is a significant reduction in noise, and it makes it much easier to listen to music or watch videos in noisy environments.

While the Sonoflow headphones do not offer as good an ANC experience as some of the more expensive models on the market, they still do a good job for the asking price. If you are looking for a pair of headphones with good ANC and a comfortable fit, the Sonoflow headphones are a great option.

The Transparency Mode on the Sonoflow headphones works well. It allows you to hear ambient noise so that you can be aware of your surroundings. This is a useful feature if you are using the headphones in public or if you need to be able to hear traffic or other sounds.

Overall, the Sonoflow headphones offer a good combination of features and performance. They are comfortable to wear, they have good sound quality, and they offer effective ANC. If you are looking for a pair of headphones for everyday use, the Sonoflow headphones are a great option.

Call Quality

The Sonoflow headphones are equipped with five beamforming microphones that are powered by an AI-powered algorithm. The microphones are very good at picking up your voice, even in noisy environments. They are also able to filter out background noise, such as traffic noise and human chatter. This results in clear and intelligible calls.

In my tests, I used the Sonoflow headphones for both WhatsApp calls and phone calls. I was very impressed with the call quality. My voice was clear and easy to understand, even when I was in noisy environments. The other people on the call were also able to hear me clearly.

Overall, I am very impressed with the call quality of the Sonoflow headphones. They are a great option for anyone who wants to make clear and intelligible calls, even in noisy environments.

Sound Quality

The 1More Sonoflow headphones have a slightly warm sound signature with an emphasis on the bass. The sound quality of the Sonoflow headphones is significantly better when using the LDAC codec than the AAC codec. This is because the LDAC codec is a higher-quality codec that can transmit more data, which results in better sound quality.

The Sonoflow headphones have a good bass response, with deep and round bass notes. The bass is slightly emphasized over the rest of the spectrum, which contributes to the headphones’ fun factor and makes them well-suited for a variety of genres. The midrange of the Sonoflow headphones is also good, with clear and realistic vocals and instruments. The headphones have good imaging and soundstage, making it easy to follow the instruments on stage. The instrument separation is also good, making it easy to distinguish between different instruments.

The Sonoflow headphones have a tuning that is appealing to people who are sensitive to high frequencies or who are new to high-resolution audio. These headphones are not designed for critical listening, but they are a good option for commuting or for everyday use. They are also very affordable, at only £90.

One thing to note is that activating ANC does have a slight negative impact on sound quality. With ANC on, the notes sound a little thinner and the instruments sound a little more congested. The resolution also takes a small hit. However, these sacrifices are not really noticeable in noisy environments, where the ANC will be doing its job of blocking out noise.

If you want to improve the sound quality of the Sonoflow headphones, you can try using an equalizer. I would recommend setting the equalizer to -3 dB in the mid-bass region and +2/3 dB in the upper mid and treble. This will give the headphones a more balanced sound signature.


Overall, the 1More Sonoflow headphones are a great value for the price. They offer a high-quality listening experience, active noise cancellation, and a comfortable design. If you have an Android phone that supports the LDAC codec and you subscribe to a high-resolution music streaming service, the 1More Sonoflow headphones are a great value, for a very reasonable price. If you have an iPhone, the Sonoflow headphones are still a good option, but you may not get the same level of performance as you would with an Android phone. If you are looking for a pair of headphones for everyday use, the Sonoflow headphones are a great option are well worth a look
