1MORE SonoFlow: ANC headphones with 70 hours battery life presented

After several excellent in-ear headphones, the 1MORE SonoFlow is a new over-ear headphone with active noise cancellation from the manufacturer. It features a superior battery life of 70 hours at a fair price.

1MORE SonoFlow unveiled

With the ComfoBuds Mini (our review) and the EVO (our review), manufacturer 1MORE has impressively proven that they have a lot to offer in the headphone segment. The 1MORE SonoFlow is an over-ear model that sounds impressive on paper.

It is supposed to realize a convincing sound with powerful bass, warm mids and crisp highs with the help of 40 mm drivers. Thanks to the support of High-Resolution Wireless Audio as well as the LDAC codec, the headphones aim to produce a clear HD sound.

The driver was tuned by four Grammies award-winning sound engineer Luca Bignardi. The precise tuning in combination with the twelve preset equalizer presets allows for high-quality audio enjoyment, which wants to convince across all genres.

The equalizer can also be adjusted to suit your preferences, while the SonoFlow can optionally be used wired via a 3.5mm jack connection.

ANC, convenience and battery life

Of course, the 1MORE SonoFlow also features a powerful active noise cancellation (ANC) feature called QuietMax. A transparency mode ensures that important audio information from the surroundings, such as in traffic or at the train station, can be perceived if necessary.

The headphones also aim to score points during phone calls thanks to a total of five ENC microphones that suppress noise from the surroundings to ensure clear intelligibility.

The weight of the headphones is 250 grams, while the ear pads covered in lush faux leather promise a high level of wearing comfort. The headphones are foldable and come with a compact carrying case.

The battery life of the SonoFlow is also impressive. The manufacturer promises up to 70 hours without ANC and 50 hours with active noise cancellation. In just 5 minutes on the mains, the headphones are also fit again for 5 hours of music playback.

Price and Availability

The 1MORE SonoFlow is available in stores now. The MSRP for the over-ear headphones with ANC is 99.99 euros, but until October 18, 2022, the manufacturer is offering an introductory discount of 20 euros on Amazon, which means you’ll ultimately pay only 79.99 euros.
