Can I buy the Sennheiser ME3 from the least expensive source and use it with the Speech Recognition Solutions adapter?
Yes! This is actually how we got started – making an adapter which would allow you to purchase the microphone inexpensively and simply adapt the plug, rather than buying a “modified” ME3 from a dealer at a significantly higher cost. Be aware, though, that if you buy the Sennheiser ME3 from a large on-line retailer you are buying a microphone with a non-standard plug and which will not work with standard audio devices as sold.
