I have purchased probably at least a dozen Bluetooth headphones over the years. All of them relatively inexpensive and all of them with ok but not great sound quality. These HE15 earbuds are quality, hands down. In my admittedly limited experience, Lenovo Bluetooth earbuds have been among the better performing Bluetooth earbuds in their price range. These are great for working out and traveling. A worthwhile Bluetooth headset that is among the best in its price range.
