I used the Yapalong and Vokkero's this weekend.. Clarity was much better on the Vokkero sets, but with that said.. I had no issue with either set this weekend. Just seem like a bit of hiss or cavernous sound on the Yapalongs.. I very much enjoy using radios, being introduced to them last year. Now, question... is there etiquette to using them??? My partner was a chatterbox!
