> [German bilabial (/w/) rather than ... labiodental (/v/)]

The sound is sometimes described as neither bilabial nor labiodental, but in
between.  IPA has a separate sign for it.  The bottom lip makes simultaneous
contact with both the upper lip and the front teeth.

Because it is an "in between" sound, English speakers often hear what it is
not, so Germans appear to the English to be saying /v/ for w and /w/ for v,
when in fact they are producing the same non-English sound for both.

Having said that, it must be acknowledged that both the bilabial and
labiodental pronunciations are also widely heard in Germany.
