Was looking for a pair of BT45's ,ordered a pair ,got a call from the seller to say they had been superseded by the new BT46 and they would send me a pair at the same cost as 45's .
Anyway had them on about 2 months now ,use the little cb for work and leisure so been used wet and dry ,honest comparison to BT45's = no discernible difference in my humble opinion, no better no worse wet or dry .
Of course this is just my humble personal opinion and it's to early to comment on wear rate.
