I like them but.... - Shokz Openrun Mini Bone Conduction Open-Ear Endurance Headphones

I like listening to podcasts while I work but, I'm required to wear ear plugs while doing so. These bone conduction headphones did what I was looking for. I could listen to what I wanted to and when I need to put in ear plugs it actually made the bone conduction louder, so I could hear things more clearly. From the get-go what annoyed me was, if I wasn't listening to anything the shockz would go into a "sleep mode". Then if I got a text message or some kind of short alert it would wake up and I would only get a small part of the tone alert. If I wasn't paying attention I would miss a text message. Other guys at work who have these have said they do not have this issue, so I'm very curious as to why mine are doing this we all have the same brand and most of us have the same model. Now my latest and most concerning issue is the headphones will no longer take a charge. Keep in mind I ordered these in May, it took 2 months to get them back in stock and ship them, and I got them mid July. Now here it is the first part of September and they're not taking a charge? Very concerned about this as they're not cheap, and I do like them but this is unacceptable.
