Are these practice mutes different?

[tbdana]

Is there any difference between this practice mute from Bremmer @ $94.00...




...and this practice mute from Selmer for $78.00?

[UATrombone]

Yes.
One was photographed from top side (about 30 degree) and has added red background while other is on white background and photographed from lesser degree (10???)...
Just kidding...
They have new mute called Whisper, but it's available now only for cornet/trumpet.
These two on photos are identical.

I like the Shhhmute for bass. Effective and light and even better than that - dent free.

... Butttt... I've got something coming in the mail that I haven't heard anyone here talking about. So we'll see what that is...

Clearly mis-marked.
