I've had the pleasure of using the Vic Firth SIH3 headphones for my drumming sessions, and I must say, they've become my go-to choice. The isolation is impressive, blocking out external noise and allowing me to focus on my playing. The sound quality is neutral and detailed, with a good balance of highs and lows. I've found the comfort to be decent, although it could be improved. The build quality is exceptional, with a sturdy design that can withstand regular use. Overall, I'm extremely satisfied with the SIH3, and I would highly recommend them to any drummer looking for a reliable and high-quality headphone.
