I have to say the 50s is the best sounding comm unit ever. I bought the packtalk bold and new 45mm jbl speaker at same time as the 50s. I also have my trusty 20s with the $100 iasus speakers (a close second). Hands down the 50s has the best sound. And plenty loud. Sena must have a decent dac in the unit. Good job sena!
