Spotty at best - ISOtunes Sport OPMOD CALIBER True Wireless Tactical Earbuds With Bluetooth, 25 NRR

Connection problems with both Bluetooth (iphone17pro) and charging. 50% of the time they both connect and work as intended. The other times only one earbud will work. It’s not always the same earbud screwing up either. Same thing with the charging, it doesn’t always charge both earbuds and I’ve ended up have to shoot with one dead earbud twice now (~3months ownership). If you want to try and clean the contacts to help with charging connectivity, DO NOT use iso alcohol (even 71%) as it will cause the finish to bubble and peel. So you can’t clean these earbuds either on top of the bad charging and Bluetooth.
