Currently, I am saving for a set of 12-Guage microphones, which are made from spent bullets - If you have not heard of 12-Guage, Google it, they are amazing!
I needed a clip that would hold very-thin microphones so I took 12-Guages recommendation and went for the spring-type clip. Having the need to purchase from Thomann anyway, I thought I would add a couple to my order.
To be honest, I probably wouldn't like a collection of these things. Call me old fashioned but I think the standard mic clip is a better option; but if you have something like a 12-Guage microphone, then these clips are the ones to buy.
Recently, I picked up an EV N/D 257B microphone. These mics have a "Warm Grip", which tends to "go hard, crack and eventually fall off". I bought my EV cheap, second hand, without its "Warm Grip" These mics are the thinnest mics I have ever seen, with the accessory not in place, and I wondered if the Holder Universal would be able to hold the microphone. It does the job, no problem.
I haven't tested it because I haven't got one, but I am guessing it might just fill in as a replacement for an AKG D112's clip. Those clips are around £15 to £18 to replace (new) so this clip could also serve a purpose for those mics whose clips are expensive to replace.
Recommended when a generic clip is your only option but use standard mic clips wherever possible. Next time I order from Thomann, I think I will buy a couple more. Now I am assured of the quality, I think they will be handy to have around.
