As you can see this is my first post on the forum, I'm beginner in the headphone/earphone gear compartment. Are 'burn-ins' really necessary for ALL earphones?
I noticed one thing as I was using these yesterday. It goes without saying but because of the shape of the tips and the how the earphones sit in your ears. What you guys might think is a good seal might not be. I noticed I have to really shove these into my ears to get a good sound seal.
If I am casual about these and just put them in my ears they don't necessarily get a good sound seal giving me a brighter than normal sound. I caught myself adjusting them and twisting them into place and the sound from a little seal to tight seal is a big difference. I know many of you guys think you are getting a good seal with these but the only way you know you are is if you can feel the tips in your ears. If you are not feeling them then you are simply not getting the sound seal or perhaps the right sized tips, you need to hear these correct.
No amount of burn in is gonna fix human error. Not having the right tip size or just not considering a tight sound seal in your ears. .They seem like you have a good seal but you have to make sure. In the end if you properly place them into your ears right they will sound right. Otherwise they sound bright and lack bass too. One way of telling if you are not getting the right tip/ sound seal is if you push into you ears more with your current tip. If that changes the sound for you than that means you are not getting the right seal or using the wrong sized tip.
So far as burn in goes. The answer to that is yes. JVC is guilty of not pre burning these earphones before selling them to the public. The reason I know this is because just how much every single JVC earphone changes for the better with burn in. Burn in makes all these earphones sound better in the long run. Burn in is very easy too and kinda fun to hear the changes. Put them into a fairly loud source and just let it rip for a weeks worth of time and you should get a better sounding FX101. First thing first make sure your getting a nice tight sound seal in your ears with the right sized tip.
@sofastreamer. The FX40 is a better option over the FXC51 imo. But for $25 those are a good purchase. Like all JVCs you do have to burn them in aggressively for a good 100 hours.
