These really sound great for such a low cost! They sound so clear & crisp, it does lack in the bass dept but I still think it's worth it. If I listen to a podcast or music the battery lasts around 5-6 hrs until I need to put them into the charging case. I do wish the battery would last at least 8 hrs, but as long as I have the case I can at least put them in there for a little bit to make them last longer & they dont take long to have a full charge. The only thing I dont like is that I dont feel like they have a good fit inside my ears so if I were to go running or any kind of bouncing around, they would fall right out of my ears & that's using the smallest size ear plugs that they come with! I really do have freakishly small ear canals though so this probably wont be a problem for most people that use these-this has always been an issue with me finding any ear buds that are small enough to make a tight fit for me. They are very simple to pair to my phone or laptop too. I like that they say outloud if it's the "primary" or "secondary" so you can listen with the primary earbud in if you want to have an ear open if your at work or anywhere you need to be able to listen to your surroundings. It also speaks to let you know when its pairing or when it pairs with your device too.I really do like these earbuds & am very happy with my purchase! I think the sound quality is great-especially for the low price! I would recommend them to anyone looking to buy high quality wireless earbuds with a low cost! They are not as good as Airbuds or Bose by any means but they are a good choice for nice mid-quality earbuds for sure!
