Hi ABSin
I finally got my Direct sound (Extremem Isolation) EX-29 headphones and used it recently to record my videos in a jamming studio to record two bands. I must say the results are pretty good. The headphones are built to isolate external sound but it doesn't isolate 100% I would say 70-80% but good enough for my application. I would recommend to try before you buy
Oh congrats. By the way, did you also try on the EX-25? I think the EX29 has the shape like a muffler. That is why it isolates well. Will go and compare these 2 models. Is it comfortable? By the way, thank you for your reply.
