I've tried a lot of different mutes, and for me, the Yamaha Silent Brass is the only practice mute I've found which comes close to working on a tuba without completely changing (i.e. screwing up) my production technique. Granted, it stops responding very well above a middle C, but that's workable. Also, I don't bother with the headphones; I just use mine as a mute.
As for straight mutes, I've tried the Tenn Tech mutes, but I'm afraid that in my opinion they're not very good, even if they are relatively inexpensive. They affect they pitch on my tubas inconsistently (i.e. some notes go sharp, some go flat) and just don't sound very good to my ears.
If you've paid around $10,000 for a tuba, and another $100 - $200 for a mouthpiece, I would think you'd want the best mute you can get, regardless of the cost. After all, at the most you'll only save about $150.
Just my opinion.
