    Shokz OpenComm2 2025: Ultimate Open-Ear Upgrade

    Purchased the Shokz OpenComm2 2025 Upgrade for work. Based on my use of numerous headsets, it is one of the top bone conduction headsets designed for anyone who prioritizes clear communication and all-day comfort. Changes from the previous model includes USB-C charging, dedicated mute button, and enhanced microphone noise cancellation. The open-ear design is ideal for situational awareness, making it great for office or on-the-go use. While music quality is average and ambient noise can be heard, the headset excels in voice clarity and convenience. Overall, it works great for calls and meetings and made for users who value comfort and multitasking.

    These are the best headphones you’ll ever buy! I can not do the in ear headphones pods, whatever brand they make! BUT THESES!!!!! These are amazing! The sound, the battery life, the comfort, the quality is better than air pods, Beats, Bose, Shure, anything on the market! Try it once and you will see what I am talking about!

    A must have for in-office and home office work

    Working in both a hybrid and open office environment, I really needed a solution that could handle both environments. No matter where I am these days, Teams or Zoom meetings are a reality. While working from home, I needed something reliable that allowed some privacy on my calls so I didn't wake a sleeping toddler at nap time. For in the office I needed that same level of privacy on calls, but also needed to be able to hear what was going on around me and to monitor my own tone while on a call. With the big "cans" tyoe headphones on, it made that hard but it also doesn't look very professional. Pros: Multiple devices can be connected to these, so you can connect both your phone and your computer. You can also answer calls from both using the multifunction button. Battery life on this is good too. I also like that it recharges using a standard USB-C instead of a custom charging cable like some other of their products. This also comes with a nice and protective carrying case. Cons: The only real con side I have to this, is the price. There are other options out there that are much cheaper, but I can say after trying a few that they don't work nearly as good. The cheaper options I tried before either had horrible connectivity or were not bone conducting. Summary - While the price may be a bit steep, this is a worthwhile investment for your in-office or WFH environment. The sound quality is great as is the connectivity. If you need a multi-device solution, this is it.
