I purchased a Neotec 2 and really like how well the SRL is designed to integrate with the helmet. However the small speakers never have and never will be sufficient at highway speeds. Sena knows this since some communicators have an audio jack option but curiously not the SRL. And because of this omission I won't purchase the SRL but instead somehow integrate my 10R with the boom mic and audio jack adapter which I use with my Shure SE846 sound isolating earphones. I highly recommend going forward that a audio jack option is designed into every communication device. Speakers will always compete with helmet noise at speed while earphones provides two solutions, reduced noise and superior sound quality. Needless to say it is disappointing the SRL was not designed with this option.
