This is a review, listening tests, EQ an detailed measurements of 1More Sonoflow Noise Cancelling Bluetooth headphones. It is on kind loan from a member and costs US $99 although goes on sale for $79.

The look and feel of the unit belies its low cost. The plastic seems stout and good quality. Pad feels soft and I like the nice large channel indicators in the red inserts. An app comes with lets you control the unit although I found the buttons very intuitive as well -- unlike many others I have tested.
Alas, the cups are just a bit too small to fully cover my ears so I can't wear them long term. I could not achieve identical response for each cup over my GRAS 45C measurement gear so consider what you are about to see approximate.
1More Sonoflow Measurements
There is provision for wired access which turns off the unit. Where possible I use to test headphones using wired mode as that eliminates impact of the BT codec. So let's start with that:

Wow, that is one massive bass peak! Followed by good depression at higher frequencies. So I downloaded the app and tried the different modes there over Bluetooth:

That is more like it. We see that the noise cancelling mode has the flattest response so I chose to stay with that from here on. For distortion tests however, I thought it was not fair to penalize it by using the 500 Hz amplitude which is the lowest for the headphone. So I adjusted the level some:

Using this reference, the distortion was surprisingly low:

1More Sonoflow Listening Tests and Equalization
Out of box response is rather pleasant although once you EQ it, you realize that much better response is to be had:

The bass was tighter and spatial effects improved. The sound is a bit bright but I was OK with it. With everything in place, the level of fidelity was shocking at times! Bass is extended nice and deep. There is plenty of volume and headroom. The clarity startling with appropriate track. As a matter of fact, despite it bothering my left ear lobe, I am still listening to them as I type this!
I perform my ad-hoc noise cancelling test to see if it quiets down the loud fans from my Audio Precision analyzer and it did that.
You don't expect much for $79 but boy, do you get a compelling package here with a bit of eq. Had the fit been better for me, I would be in the clouds! FYI, I heard in some review they may be adding custom EQ in the app for this headphone. If so, that would make it near perfect.
I am happy to recommend the 1More Sonoflow wireless headphone. Even without the sale it is a good deal but there was one on Amazon last night so might as well take advantage of it.
As always, questions, comments, recommendations, etc. are welcome.
