I found these to be a comfortable set of Bluetooth earbuds. Their sound quality is not what I expected after reading the listing.I have been using a pair of mid-level Sennheiser audiophile headphones for several years, and a pair of Edifier NEO Buds Pro. Those two are much higher priced and provide a more flat response over the full frequency range of sound from lows to highs. These headphones are at a much lower price point, have a very different sound quality, and are not in the same category.For the price, I think they have some issues. For starters, the listing advertises they are "bone conducting" but they are definitely NOT bone conducting in any way. They clip onto the ears and do not have any vibrating components. They also do not contact any bones as they are clipped to the ear. Additionally, due to the way they fit onto the ear, the lower frequencies (i.e. bass) are inaudible.Fit - The earbuds are very light weight and clip onto your ears, which makes them feel very secure to me. - They stay in place pretty well. I haven't tried them during vigorous exercise, but shaking my head won't make them shift or dislodge from my head. - The way they attach to your ears, they don't interfere with wearing glasses.Sound Quality - The way they fit on my ears, they are very treble oriented, but they could be very nice sounding across all frequency ranges. The way these attach to my ears, they don't get close enough to my ear-holes, so I loose ll of the low end of the sound. When I press them closer to my ears, they sound fantastic to me. If these fit into the ears, they would be perfect.With the way they fit onto my ears ( and 2 other people who tried them): - The highs are a very clear and detailed to me, - The mid range is a bit muted to me, a lot of details start to go missing because they are too far away from my ear canals.- The bass is completely missing unless I press them closer to my ears. When closer, I find the bass to be clear and punchy. - These earbuds do not have active noise cancellation. They sit a little outside the ear canal and do not block or isolate in any way. - The volume is quite loud enough - I keep them at less than half volume.Phone Feature - The listing mentions something about phones, but I did not test this feature. I also didn't see anything about a microphone on them.Battery Life- The listing says they have up to 6 hours charge on them. I did not test them long enough to verify the battery life.Verdict- If you are looking for Bluetooth earbuds that feel secure and allow you to hear your environment then these may be a good option for you.- If you are looking for more balanced sound then you might not like these headphonesFor me, I find that the missing lower frequencies made them unsatisfying to listen to. I might use them when working out for shorter sessions, when I need to hear my environment.
