Sound quality mediocre and much worse than the predecessors I owned. After a few times of use they start to make bery loud shattering noise on the left earpiece and the battery only lasts 2 hours (!)
the predecessors simply broke on the ear holder because of bad plastic quality. So this my second Jlab product not living up to what it should
Love the audio clarity & ear-comfort when in use! My only drawback is that I have to charge them up daily. But that's a small matter when compared to the fact that conversations come through back-&-forth CRYSTAL CLEAR AS A BELL, and there's NO PAIN behind my ears like with other Earbud Hooks!! Will definitely buy more of them in the future as needed.
