Killer B's..
Just wanted to pop this thread back up and add: if any Tesoro users are looking for great headphones, you don't need to look any further than the "standard" model Killer B's. Unless you're constantly crawling through a thicket or you have one bad ear, you don't need anything fancier than the KB's base model. The fancier model Killer B's have a better cord strain relief, or dual volume controls, or a limiter switch, or bigger cups (Hornet), or some combination of those. They all share the same quality cord though, and have the same Audiosears speakers and same leather headband and ear pads.
The least costly of the KB's is a great headphone for Tesoros, and probably all most of us need. Thought I'd mention that 'cause I started out with the "Wasp" model, but didn't need the limiter or dual volume controls. I recently bought the base model as a backup set, and found that it's lighter, cheaper, and all I'd need with a Tesoro.
BTW- the Sun Ray Pro Golds are made by John Smith, the same guy who makes Killer B's, but they're made with features to Sun Ray specs. They're pretty much the same headphone as the Killer B's Wasp, but instead of using locking toggles, they're standard ones with rubber dust boots on 'em, and they have Sun Ray's logo instead of Killer B's. They also have more features than a Tesoro user really needs.
Just get the base Killer B's. Great headphones and John Smith is a good guy to deal with for warranty repairs, if you ever do need 'em.
