Congrats on getting the Tiger Shark. Hope to hear how you do!
My experience, not a Tiger Shark but, the headphones with my Sand Shark are solid, isolate wave noise very well and are clear. They look simple and are fairly light but perform well. I've been rolled by waves, knocked the headphones off my head, got wrapped up in the scoop and detector, dropped the head phones on the ground while walking up the sidewalk towards the water more than once and every thing still works very well. The only failure I've had is when I got rolled by a wave and stood up on the coil. I couldn't see a crack but the detector started sounding off as waves washed over the coil. New (used) coil fixed that ... and that is an easy swap with the Tesoro.
I don't believe Minelab still modifies their waterproof detector with connectors for either the coil or the headphone. They used to, for a price, if you requested, but not anymore. All hardwired now unless you do it yourself and void their limited 3 year warranty.
