We bought these headsets for our travel agency. They look big but are very light. If I get more, I'd probably want something more discrete. The battery seems to go all day and my staff like them, just one employee won't wear it cos it messes up her hairdo! |

| Good sound & battery life but looks a bit bulky (though, to be fair, it doesn't feel heavy) | |

I don't like things poking in my ear so I got the CS351N headset. It feels very secure and I like that I can adjust the volume & mute the call even when I'm not near my phone. I just wish I could transfer calls with it too but apparently no headsets can do that - please can you pass this on to the manufacturers? I'm sure lots of people would buy them. |

The headset is ugly compared to some of the others we looked at but it fits our needs. It's heavy duty and the way staff treat headsets in the office that's what we needed. |

| We did our research and the 351 was the headset we chose. Simply offered the lowest pricing and the service was also spot on. We'll be back again! | |

The 351N is solid and exactly what we needed. Tom throws it wround a bit and we know it's going to last. Some of the other headsets looked a little flimsy. Good advice and a good headset. |

Great deal on price compared to other companies and simply was helpful and offered to walk us through setup but we figured it out ourselves and was actually pretty simple. Love having my handsfree! |

The headset is a little bulky but very robust. At least we know it will last and won't break easily. Great sound quality and the service from the Simply staff was refreshing. |
