I couldn't find that many opinions online so I thought I'd throw in my two cents. A bit of background, I'm a bit of a headphone enthusiast but nothing crazy - my main headphones are the the HD650, HD620s, and previously the AKG K701. I use the Etymotic er3xr on the go in addition to some random wireless Sony bluetooth earbuds. I also have the Bose QC45. I bought the OpenFit 2+ as an upgrade over the OpenFit Air which I currently own as a pair of cheap(ish) open headphones for situations where I'd like to hear the environment outside. To be honest the old OpenFit Air are kinda bad but they are cheap and are tolerable for some background music. The OpenFit 2+ are a substantial improvement and actually provide decent sound quality. Overall I'd describe the sound signature as being overall pretty well balanced and slightly V shaped with plenty of treble sparkle. The treble resolution isn't amazing but it's hard to fault given the category doesn't have that many contenders. The sub-bass rolls off a little as well which is expected for this form factor, but bass extension is surprisingly good. Soundstage is good, reasonably wide, which is not exactly surprising given V shaped sound signatures does tend to assist to that effect. Compared to my er3xr, the Shokz has a laid back midrange with a hotter treble and is of course less detailed across the board. It's brighter than the HD650's with a rougher less refined sound. I bought them for $339.00 AUD, I'd highly recommend them for anyone who is after some open sporty headphones and is willing to pay for good sound quality.
Yeah the 2 is a significant step up. I don't know how they compare with the Ultra Open.
The shokz openfit 2+ are a little pricy but awesome.
Compare JLab Go Sport+ vs Shokz OpenFit2+. The price difference is about $170.00. I have both and think the JLab does a better job at filtering the exterior sound as long as you have the right fit on your earpiece. JLab has decent sound quality. Shokz is amazingly better.
I'd highly recommend the Shokz OpenFit 2+. They're super comfortable, the sound is surprisingly good, and you can still hear everything around you. Wireless charging ung case and ok ung battery. Be careful, though. They're so comfortable it's easy to forget you're wearing them, which makes them easy to lose if they drop. That actually happened to me once, but luckily, I was able to backtrack and find it.
I loved my Shokz Openfit 2, because they sound darn good enough, are crazy comfortable, and allow me to stay aware of the world around me which is generally appropriate when I'm playing. When I'm able to get lost in the game and ignore the world around me, then like my Sony XM4s. I just upgraded to the Openfit 2+, and need to sell the Openfit 2. They're basically the same, but the 2+ support Dolby Audio and wireless charging.

I loved the sound of these buds! Fit was mega secure too - sadly after wearing for a few hours I realised that the ends push up against the cartilage on my antihelix of my ear… Went from “this is the most comfortable earbud ever” to “excruciating pain”! Sold them, but would insta-buy another pair if I found some that didn’t have that same issue
