I have the Widex SmartRIC 220, and would buy them again. They are comfortable, have musical audio quality (Widex works with musicians), very low latency (reducing comb filter effect), and in general look and feel very professional.

As for technology, they use bluetooth low energy to connect to the smart phone, which works really well, with the caveat that the range is quite low and if it is in the pocket and you are moving around, media sound will often disrupt or desync intermittently. On the plus side, they last well over a day even with media use (WIdex says they last 37 hours without bluetooth use and that checks out). The case provides charge for about a week, and has wireless and usb-c charging.

They are quite pricey, but there are several options (110, 220, 330, 440), and the 220 were more than enough for me. The app has several modes, including directional focus mode, and you can define your own. I sometimes use a different mode for listening to concert music, that disables most filters such as volume protection.

I am wearing them for 9 months now, and there was no situation (concerts, traveling, work, sports, etc) were they gave me any issues whatsoever.

I've been seeing good things about Widex and it's got me curious to try.

I'm using Widex Allure. I only need to use one ear for now, and the low latency from the Widex was what won it, tried a couple Oticons that had a disorienting amount of lag. Also the Widex has really great high frequency transient filtering, much better than the Oticons in my experience. With a house full of screaming kids, this was also critical.
