I recently bought these as my first pair of earbuds. Jury's still out; having trouble fine-tuning the size. Finding them difficult to retain in my ears, they feel.. awkward. Like the charging case, overall hopeful.

Purchased these one the recommendation of The Wirecutter (NYT) and couldn't be happier! The noice-canceling feature is AMAZING for airplanes and other environments with loads of background noise.

Unbelievable sound once I found out you needed to download the app for these….once that happened wow the sound… the bass and the quality were awesome!!!!!

Had them for just about two weeks. The worst experience I have ever had with headphones. Sometimes they just shut off and won't turn on again. Constantly falling out of the ear, unpairing. Very poor sound canceling. Just a terrible set of headphones

Everything is great so far, except one of my already small ears is smaller than the other, and the smallest earbud still doesn't work. Please manufacture (and sell) extra small earbud tips.

Have had these for several weeks now - use several hours/day at work outside and absolutely love them! Have not downloaded the app yet but that is supposed to have even more control features which is exciting.

I was looking for earbuds that would stay secure during runs and other workouts, and these sure so. The active noise cancellation isn't the most powerful/effective, but I don't need it to be.

I purchased the product a few weeks ago and wear the earbuds to the gym. The sound is fantastic, blocks outside noise, and are comfortable to wear. I'm pleased with this purchase.

I saw the price and the ear buds and I had to buy these. Same JBL sound quality that has been in my family since my first 4311 studio monitors from 1978.

I bought the ear buds opened them up charged them and the left earbud never charged. I followed all directions to clean them and still the left one does not charge or work at all.
