I told myself I would only get one iem per month, and I ended up getting three this month. The IE 600 and Ej07 aren’t even a week old, so there’s still tons of listening to do. The only other iem that I have my eye on is the Monarch mk3, but that’s still on back order on headphones.com. Other than that, I’m pretty happy with this collection :)
Thank you for your answer. I can understand, that it can be tempting to listen to something and then change the IEMs/headphones and listen to the same stuff with different signatures, but to be honest, how often would you do that? I totally agree, that every single headphones/IEMs have their strenghts and weaknesses, even to most expensive one, so to have a collection of best trebble, best bass, best soundstage etc. makes some sense. In this case you had a specific album, where you just love the bass for example and then switch to the right IEM. But then again, how often would you do that? But as I stated before - it's totally fine for me, don't get me wrong, it's your money and your hobby, was just curious.
My case is completely different, I'm in that hobby for over 20 years and had probably under 10 IEMs and 3 or 4 headphones in all that time. But almost never more than 2 at the same time, the second one as a spare, I sold or gave the older ones to someone. I'm pretty sure, that even if I had more IEMs/headphones, I would be too lazy to use them all, would always use the most "universal" one.
