I liked the SASS rig the most. The teliga omnis performance is really very =
good considering the size 10mm, this may take some getting used to, its lik=
e having a pair of large diaphragm condensers in your pocket. Quite a disru=
ptive product if you think of the low noise, sensitivity and cost, no need =
for xlr/phantom power, pocket recorder 3.5mm plug and go... I hope they are=
 waterproof?
