Good stuff They fit great and dont fall out while I am doing very vigorous and all over the place workouts. I would compare their sound to regular Apple earbuds. Case fits well and protects my AirPods. The main reason for downloading the app is to update the firmware of the speaker. Finish/Durability: These are plastic headphones, and are definitely not indestructible. I got a basket for the front for my dog (cavalier king Charles), because he wants to come along too. Pairing is also very easy - just take them out of the case and the light blinks for both, turn on bluetooth and it pairs easily. Im not a professional photographer, but hopefully my beautifully overexposed photograph showcases the variety of lights available to you. Amazon description says load is 135lbs, it instructions say 165lbs.
