Review on 🎧 Cutting-Edge R9 Earphone: Wireless Bone Conduction Headphones with Bluetooth 5.0, Quick Charge, Long Battery Life, and Free Ears Design for Optimal Sports Experience by Tanya Reed

Over the past few months the sound in one of the headphones has steadily deteriorated (grainy, distorted - as if the speaker had burned out). Today I only hear noise from the other side, nothing at all from the sound source. You just have to throw it away at this point. Six months isn't long enough to justify a purchase, let alone a second purchase. I was always dissatisfied with the volume - with bone conduction, the level was never high enough and was always drowned out by ambient noise (I only use it for audio books). Putting it on my ear helped, but then why did I get bone conduction when I have to put speakers on my ears? And they'll never stay in my ear because they're engineered differently. UPDATE 2/22/20: I've replaced them with another brand of Bluetooth bone conduction headphones in the same price range and they're just perfect, all that was missing -- good volume even in traffic, good sound. Combine IP56.
