Short story: these are amazing. Get them or the Drop version
Long version: New job duties have me in front of my desk less, so I’ve been spending more time using my iems than usual. I’m not the biggest iem guy. I own Andromedas, BL03s, and P1s and a few others I rarely use. The Andromedas have always been my favorite iem. I think they sound closer to a full headphone than most of the other iems I’ve tried, but they are bright and can be a little fatiguing. I decided I wanted to look for something else, but I didn’t want to spend a ton of money-nothing close to the cost of the Andromedas.
I think my issue with iems is the way BA drivers sound. It’s pretty refined on the Andromedas, but still not my preference. I guess its the timbre? I tried the P1s hoping the switch to a planar driver would work for me the way it did for other people, but it never grabbed me. I thought about the Shouer Tapes, but I remembered I had done a little research on single dynamic drive iems and read how some people raved about them. I prefer dynamic headphones to planars, so I figured I’d give it a shot.
The JVC HA-FD01 is a weird idea. It shipped with 3 interchangeable nozzles-steel, brass, and titanium, but other than the metal it was made out of there was no other tuning done with each nozzle. So all 3 sound exactly the same. Pretty stupid, but if you do the simple mod spelled out by james444 at SBAF here https://www.superbestaudiofriends.org/index.php?threads/jvc-fd01-a-new-contender-for-best-dd-iem.6500/ , these go from super bright to pretty incredible. I may only be using these for portable for the foreseeable future and may end up selling the Andromedas. This tiny strip of rolled up gauze combined with whatever it is the dynamic driver is doing fixes all the issues I have with most iems. I’ve been listening since Friday and I prefer them to a lot of my headphones too.
Drop has them in stock for $240 right now. They also supposedly had their own version- the DROP + JVC HA-FDX1, but I don’t know that they will drop again or what the cost was. The difference is they apply the mod themselves so you don’t have to. If it costs any more than $250, I’d honestly just do it yourself. I’m not the modding type, but this took me a total of 2-5 minutes mainly because of my big dumb fingers. For $240, I couldn’t recommend these more
