It’s easy to install the app on your phone and I am happy with my purchase. I have been using this Jabra Speak 510 Plus now for a few months and having previously used a Sennheiser model can confirm that this is the best Conference device ive used. I have owned many different brand headphones, I found most of them were overrated on the internet, I started wondering how many paid reviews are there. Installation is done within 5 mins. Not right for me at all. The heel cup is very cushiony and springy making them perfect for every day wearing. I have very tall cabinets and these fit perfect in my spice cabinets to double my shelf space. They can be tricky sometimes to get on as there is no strap to open but the elastic means a comfy fit. I bought 3, one for me, one for my daughter and one for my husband. Had to break them in but after that they have been my favorite shoe the last couple months!
