My new favorite pair of earbuds. I was impressed pretty much right away with how full and rich sounding these sounded right out of the box. Typically I've found that you need a bit of a "burn in" period for most of these less expensive earbuds to truly know how they will eventually sound but these had a very balanced frequency range right off the bat with crisp clear highs and controlled but noticable bass response. Finding a pair in this price range with the Qualcomm aptx chip is not that easy as well. I've had no connectivity or syncing problems whatsoever. The 5.0 dual ear feature is pretty much a must now after using it a few times. You will never want to go back to just a single left or right bluetooth setting ever again. The earpiece that is came with fit my ear perfectly but some might find it necessary to use one of the other sizes depending on your ear canal. It's a good idea to experiment with changing these because it makes a big difference in the overall sound quality. I love these earbuds and I would definitely recommend them to anyone looking in this price range. The quality for this price range is definitely competitive nowadays and these are some of the best I have tried for sure.

The compactness of these I really enjoy. They sit well in my ear without moving at all. They do not make my ear sore. They do completely block out the ambient sound. You can 1/2 insert them in your ear if you are not moving much and that way hear more external sound. I'm wondering if I can drill a hole in the ear pad to make this better? As it is, when I am not listening to anything I remove them because its blocking too much sound. But they are easy to remove and put back considering they turn on and off automatically.

Its nice that this charging dock shows you the percentage of charge that it currently has when you open the plastic door. On that bright LED screen, it also displays how much charge each earbud has. This has been a nice feature to have because I know how charged my earbuds are so they dont die when Im out and about. It was simple to connect to my iPhones Bluetooth and fit comfortably in my ears. Ive even played tennis while using them and they dont fall out. They are very immersive because they block out any sounds around me.

This is my fifth pair of Bluetooth headphones and by far this has the biggest sound. There is a LOT of nice bass here. It's downright thick and punchy, but not sludgy. The mids have a decent kick and the highs sound pretty crisp. I've turned the volume all the way up and there was no distortion. These sound absolutely fantastic.

These are great for some EDM, Techno, Dubstep, or Rap. I listened to a bit of Queen and it sounded a little bassier than I'm used to, but wasn't bad. Classic rock might need a little adjustment on the equalizer. Classical sounded pretty good, though...Wasn't expecting that. Chopin, Vivaldi, Aaron Copland, and even Carl Orff sounded fantastic.

Battery seems to be exactly what it says on the box. I listened for about four hours and my battery monitor was showing 50% used. I was able to fully recharge from 50% in the case in less than an hour. When complete, case showed 79% charge available.
