is this hd 60 battery a genuine epos Sennheiser battery or an equivalent one? I need an exact one becaause the so called compatible ones do not charge properly Thanks

I can confirm that this is a genuine EPOS / Sennheiser part. I have updated our website to make this clearer. I checked stock and we don't have any on the shelf here and no back order to bring more in for stock, however I have checked with Sennheiser and we can still get them for you, but just note that there's a 7-10 day estimated delivery time on them.
