Great upgrade from original Trueair earbuds. Smaller, slimmer, better designed, excellent Bluetooth connectivity and they come in BLACK! Pros: 1. Overall size of case and earbuds is perfect 2. Flat case means they are much easier to open. I found it very difficult to keep the lid open on original Trueair. 3. Improved QC Bluetooth chip clearly makes the difference. Switching between L and R earbuds OR adding one after the other is instant and streamlined. 4. Looks of earbuds are better. 5. Battery Life is excellent
Cons: Lid on the case could have opened a bit more. I get nervous about breaking it by opening it too far out.
