i think they sound nice as long as you like stacking, which you might not always be able to do, and dont move at all because they are do sensitive you can hear swishing with the slightest movement
I gotta call BS on both counts. How many times have you worn 4061s?
The suggestion that they are only appropriate for stack taping is just way wrong, as countless sources demonstrate.
Same for 'swishing with the slightest movement'. As an omni, they should be less prone to movement induced phase or wind issues than a card or hyper. They are way less sensitive to cable or body handling than my AT853's were. I regularly wear schoeps cards and hypers at 40-55dB of gain with no 'swishing'. So wearing omnis, especially at the lower levels required for rock shows, is cake.
I bought mine used on ebay and changed the connector from lemo to miniplug. I was fortunate to get a good pair. The ebay DPAs are a bit of a risk. That is especially true if you need to change the connector in order to test them. You can't really cut and solder them and then send them back saying they don't work right, etc.
