Sennheiser SP 20 ML is a portable speakerphone designed for business professionals using PC / Microsoft programs like Teams, WebEx, Skype, etc. on PC, mobile phone or tablet - for both personal and small group conferences.
Clear speaker and microphone great for travelling. Out performs smartphones with clearer sound and better pick up. No drivers needed - just plug in and us. Can sell with Apple Lightning to 3.5 mm Headphone Jack Adapter too. If using USB-C (new Mac/PC or iPad), you can pick up an adapter online for ~$10.
Works well and much better for voice pick up than phones / computers are.
