You can change every room into a conference room with the Sennheiser SP 20 ML. Connect the beautiful and powerful speaker to your laptop, PC, smartphone, or tablet and talk to colleagues from Japan, the US, Vladivostok, or Biggekerke. The speakerphone has different technologies to make the person on the other end always sound crystal clear. For example, it has an "echo cancellation" feature, so you can even have conversations on the toilet. The controls of the SP 20 ML are child's play, with large buttons to start or end conversations. It works perfectly together with most communication software, including Microsoft Lync.
