I've spent a little over 2 weeks with the Jabra Elite 75t's and i've got to say overall i'm really, really happy with them. The bass is ridiculous, like stupid and they def. need to be Eq'd. I made a bunch of custom presets in the app and now that I have, These things really really perform. Mids are great and the highs are beautiful. I'm using some wide bore medium tips I found somewhere, they are akin to the RadioShack tips but they are shorter. I've been using them for phone calls and Zoom daily and also Go To Meeting. They are hands down the best TWS i've used for calls. I get a lot of comments about how good my voice sound with them. They do have their hiccups when switching from my PC to my phone. I just make sure to disconnect them from my PC when I leave my office, but I can easily answer calls while gaming on my PC with them. They are an all around performer The transparency mode is also excellent and depending on the tips you use, i'd say it rivals the APPs, especially now that APPLE destroyed the APPs with their latest firmware update. (My 3rd replacement pair will be here today
) Anyway, The app is also fantastic, It has the EQ, Call settings and some other options. You can't program the buttons, but it hasn't bothered me at all. The have mute/ambient on the left and volume down. on the right is play/pause, Siri, answer call and Volume Up refubs are $100
