Review: Clear Quality - We use these combination speaker/microphone in our office for Microsoft Teams and Google Meet meetings. Excellent sound quality compared to built-in laptop devices. Highly recommend
Review: So good, I bought 2 - I initially purchased one because I am working from home and I was spending too much time on conference calls with a phone wedged between my ear and shoulder for hours every day, slowly turning myself into a quadriplegic with neck pain and headaches. I tried several of the cheaper units and promptly processed a return for all of them thanks to horrible audio, echo issues and crummy mic sound quality ("you sound like you're talking into a can"). I tried the computer audio and mic but it was so bad that no one could understand me and I couldn't understand half of the people who were talking either. I purchased this unit on a whim. I love my Sennheiser head phones and these speaker phones are equally good quality. Everyone is easy to understand, mute is clearly highlighted with red lights when it is on and no one has had to ask me to repeat myself since I started using it. Well, then my wife started working from home thanks to COVID and I let her use it for one of her meetings and we spent the next week handing it back-and-forth and scheduling time with it. The first meeting conflict hit and I'm sure you can guess who ended up with the phone back against their face again. So, now we both own one and we are both extremely happy with the purchase. It was very much worth paying double what the cheap units are going for. So far it has worked seamlessly with WebeX, Gotomeeting and zoom. You just need to remember that the meeting application isn't going to understand that you plugged this in, you will need to select the audio settings and choose the Sennheiser for the speaker and then the mic. I can wholeheartedly recommend this for purchase if you spend any time in online meetings.

## Questions & Answers

**Q: Does it have echo cancelation?**
A: Yes, and it works great.

**Q: Can you this with an desk phone via the headset jack?**
A: The EPOS Sennheiser SP 20 isn't marketed to be used with a standard desk-phone.  The exception to the rule is that many newer desk phones do in fact have USB ports which support audio in which case this would be a perfect way to expand the speakerphone capabilities on a budget.

**Q: What is the difference between this model ml  and the regular sennheise sp20 usb?**
A: The SP 20 is designed only to be used with PC's, smartphone, and tablets.  The SP 20ML is designed to be used with Skype for Business, PC's, smartphones, and tablets.  I have the SP20 ML and love it.  I use it everyday for both personal and business.

**Q: Can you this with an desk phone via the headset jack?**
