1MORE SonoFlow Pro: In Review
Affordable ANC headphones, now with even more battery life
We’ve been able to spend a lot of time with a variety of the headphones and earbuds from 1MORE, and their over-ear headphones have been coming with a very compelling balance of functionality and pricing. Their latest, the 1MORE SonoFlow Pro, give a solid upgrade to battery life, as well as including a handy wired accessory.




1MORE SonoFlow Pro: what they are
Obviously, the 1MORE SonoFlow Pro are a set of over-ear headphones. These are wireless, most of the time, but they can also be wired, as they have a 2.5mm jack in the right earcup. This is where the accessory comes in. While it definitely is a wired cable, it also packs in a play/pause button, which is handy to use.
It’s with this wire that we start to see some differences from the non-Pro version that came before. With the 1MORE SonoFlow Pro, you do have to have the headphones charged to use them in wired mode. Why is that? Well, it’s because you can actually use ANC while wired, which is something the prior version did not allow (that said, you can the non-pro version wired even with a dead battery). So, you’re going to be worried about battery life, right?
Not really a concern here. Battery life is drastically improved, with an estimated 100h (with ANC off; 65h with ANC on) as compared to the 70 hours that the non-pro version offers. How did they accomplish that? There may be other things they’ve done, but our hunch is that the move from Bluetooth 5.0 to 5.4 allowed for a more efficient radio to be in the mix, help extend your time between charges.




Wrapping things up
At the end of the day, the 1MORE SonoFlow Pro headphones are very, very similar to the non-pro version. They both are styled similarly, and both come with a hard-shell travel case and charging cable. They both perform simililarly (as judged by my non-calibrated ears), and offer the same levels of comfort on the head.
However, the Pro does bring that extended battery life, which is nothing to sneeze at. They also seem to have worked on the hinges in the headband and the earcups, which helps cut down on the creaking you sometimes here. And, yes, there’s also that wired cable that adds in the play/pause button.
What’s interesting here is how these are priced. Funnily enough, when you look at the list price, the 1MORE SonoFlow Pro is actually a few dollars cheaper than the non-pro version. However, with the current discounts they have, the 1MORE SonoFlow Pro comes in at $87.99 (vs $74.99 for the non-pro). To us, that slight premium is well worth it for the improved battery life. However, if you need to be able to use the headphones in wired mode even when the battery is depleted, you’ll want the non-pro version. You can get yours directly from 1MORE, or over at Amazon (where the current coupon drops the price to just over $70!)
