Wonderful battery life

Vibrant and fascinating mids

Sturdy EQ assist from the app.

It has been a while since a 1More full-size headphone was on my noggin’. I’ve had some expertise with their IEMs up to now such because the Triple Driver and Quad Driver, so lastly getting the possibility to listen to one thing new and full-size from them was an actual deal with for me.

Wi-fi, LDAC, and ANC for reasonable? Signal me up as quickly as attainable, please and thanks! There will be no counterargument that for the value, the SonoFlow is a cut price and a half.

Over the overview course of, I discovered myself reaching out for this headphone, on the go, increasingly more over time. Consolation, high quality, and responsiveness. These are all containers I had checked off early on.

Tech Highlights

The 1MORE SonoFlow is a wi-fi closed-back moveable headphone with each lively noise-canceling and as much as LDAC decoding functionality through a BT5.0 succesful SoC.

It additionally provides a dual-device connection and clear name assist utilizing 5 ENC mics. You additionally get ambient noise management, app integration, and wired assist in case you need to play it a bit ‘old fashioned’ and lengthen the battery life.

Proprietary ANC

1More has developed what they name “QuietMax™”, which appears to get the job achieved pretty nicely, contemplating the finances pricing of this mannequin.

I’m certain lots of people are going to attempt to copy this within the subsequent yr or two as a result of it performs very nicely for such a low price. I do take pleasure in transparency mode, which helps you to cease the ANC and listen to what’s up round you. I like options with any such functionality.


The 1More SonoFlow makes use of a 40mm dynamic driver with a DLC (Diamond-like Carbon) composite diaphragm in a closed-back design.

Grammy winner Luca Bignardi has tuned the SonoFlow to his liking and I wish to purchase him a beer if we ever meet. He appears to know musicality and enjoyable elements should not misplaced causes within the audiophile circuit, and that makes me actually completely happy.

The headphones themselves should not overly exaggerated on the bass finish, however it’s agency and may develop into potent with the suitable EQ. It is a headphone that barely leans in the direction of a musical flare in tonality.

The SonoFlow is a closed-back over-the-ear design, pretty light-weight, and really snug. In actual fact, I haven’t seen one other headphone like this use these extraordinarily mushy leather-based imitation supplies for the reason that FiiO EH3 NC.

Sivga used an identical sort not too long ago within the Oriole, however they weren’t ANC headphones. Apparently once more, the dearer and newer Clear Alpha ANC makes use of inferior pads than this less expensive SonoFlow.

The design is extremely interesting to me. It isn’t as giant as another ANC fashions such because the uber high-end Mark Levinson No 5909, but it retains an awesome match for me with none discomfort.

I give the SonoFlow excessive marks on the consolation ranking. The caliper stress is pretty gentle and mixed with tremendous plush pads, the headphone finally ends up being one of many extra snug units I’ve used all yr.

1MORE SonoFlow Review


The SonoFlow isolates very nicely, for the value. For simply $99, it is a steal and I think this can be a pleasant possibility for individuals who don’t need to spend extra on a Bose or Sony variant.

With out the ANC on, the isolation remains to be fairly good and noticeably higher than different closed-back headphones I’ve that wouldn’t have any ANC in them.

Tapping the ANC NoiseMax activation button on the earcup is able to completely drowning out the sound of bathwater or a bathe, and loud field followers, even a TV close by are considerably dimmed down. ANC scores are superb for the SonoFlow, spectacular even for the value.


1More cites that the SonoFlow is able to 70 hours of utilization, whereas I’ve discovered that quantity to be a good bit under the 70 mark.

Nonetheless, although, the headphones cost in a short time and can provide a couple of hours of utilization with simply 5 minutes or so of fast cost juice. Even 40 hours is a fully gargantuan quantity of utilization in a single smaller headphone like this, and I’ve obtained greater than 40 hours.

The utilization cycle appears to rely on which mode I’m at present in and what the quantity ranges are. I’d say 40 hours is common with ANC lively. And that’s magnificent. An 8-hour journey with ANC solely degraded the battery by about 20% or so.

Customized EQ

App Integration

You may jump over to the Android Play Retailer or the Apple market and obtain the 1More Music app. Doing so will unlock a slew of EQ presets and also you’ll additionally need this for entry to quick notifications about firmware updates on your 1More headphones.

I’m most keen on the Vocal Booster possibility, which upticks the midrange and lower-treble areas a tad to permit for a extra ahead and fascinating presentation. It does appear to tank the bass amount a bit, so I often solely use modes like this for YouTube, films, or gaming wants.

Whereas paired wirelessly, the EQ units within the app are designed to offset the naturally missing tone and heft that immediately comes with wi-fi connections. These tone points embrace basic physicality and a robust sense of depth.

Nevertheless, oddly, with lively noise cancelation mode lively, the bass high quality in wi-fi mode outperforms wired mode, which is likely to be a bonus for homeowners.

Voice Name High quality

Name high quality is common for a $99 tier headphone. Noticeably hiss within the background and a pronounced forwardness on the receiving finish had been the tip results of my testing.

The expertise lacks a way of bass depth within the voice, which as a substitute takes a extra crystalline thinness tonality method. I frequent the app Telegram in voice chat mode usually, and I’m advised that my voice whereas paired with my telephone and this SonoFlow is a typical sound high quality that’s offered to the bottom listening to me.

After I swap to one thing just like the Sennheiser Momentum 4 (3-4x the value of the SonoFlow) I’m met with reward for the way glorious my voice sounds.

Now, regardless of that, we must always not denounce the SonoFlow in any respect. On the $99 stage, the standard of the voice expertise by means of gaming chat and regular telephone calls is simply good general.

Inventory Cable

I don’t have an excessive amount of in the way in which of ideas on this. The inventory cable is generic and certain not even supposed for use.

One earcup has a 2.5mm port in case you do need to use the wired model 3.5mm terminated cable, however I’m not certain why you’ll ever need that, as a result of the ANC mode enhances the bass and crispness of the expertise audibly so and the inventory wired expertise solely lacks that dynamic.

At this value level, I actually don’t care what cable is used and particularly not for an ANC sub $99. Odds are good I’ll by no means contact it once more.

Packaging & Equipment

The 1MORE Sonoflow field is pretty customary, together with a pleasant exhausting zipper case, a 3.5mm cable, a USB-C charging cable, and the headphones themselves. I do take pleasure in the way in which the SonoFlow is neatly folded whereas within the case to avoid wasting as a lot area as attainable when on the go.

The USB cable is Fast Cost enabled, testing with a voltage app confirmed it could possibly deal with it. Search for a lower-tier older fast charging system that doesn’t output greater than 25w or so.

A small experiment was run, the SonoFlow won’t cost any sooner with a really high-quality quick charger vs a lower-tier one. They cost the identical fee, so simply seize an affordable one which places out like 20w fast cost and save your self the difficulty of shopping for an costly brick for that. No want.

5 minutes on fast cost = a couple of hours of playback, which is great. Take into consideration that. Your flight is in 10m and your battery is useless and 0%. You forgot to cost it. Discover an outlet, typically airports have them on the ready foyer space seats, 5 minutes will get you a couple of hours. Amen.
