@Jalo the lab ii has some limits with deep bass due the open design, so a bit limited with electronic music. but even if they have both a single large dynamic driver the design is different. the lab 2 has a ultra thin 6 μ thick diaphragm (most dd are around 12 μ thick), the ha-fw10000 on the other side has a driver which thickest part (wood) is 50 μ + base( if its a sandwich construction) around 60 μ. so one driver is ultra light and the other thick and i think heavy. that something you realized fast when you listen to the ha-fw10000, the lab 2 is faster and super easy to drive. the ha-fw10000 gains quality and resolution with a powerful amp, thus this is needed to get the most out of it. imo the jvc has a good resolution but not as superb as the lab2. the price the lab2 pays is limited sub bass / general bass power where the jvc is dominant and powerful in this part. both are musical natural sounding earphones, stage is bigger with the lab 2 (a tad to big / imax effect). lab 2 is more neutral, less colored. both don't have excellent upper highs (jvc a tad hot upper mids/lower highs, but easy to correct with the right gear). fine for dynamic drivers but due the nature of dynamics drivers electrostatic oder magnetoplanar system are better (if well made). imo these system can deliver more - dynamic drivers lacks often the speed and extension even if the well tuned/made. for me technical limits of the general desing of a full range dynamic driver. but overall nothing that you miss, only notice if you listen for. but it's not a fair compairson, the lab 2 has a extreme complex housing with a mechanical equalizer build in the 3d printed titanium case. this and a high failure rate when the lab 2 driver was assembled pushed the cost up, nearly 3 times the prive of the jvc. imo the lab 2 has some if not the nicest mids i know (earphones or headphones), the tibre and decay in this part are brilliant. due the limits in the bass this earphones plays perfect with a lot of analogue music, struggles a bit with electronic/edm tracks. the jvc is a very fine allrounder with a pleasing (asian) audiophile sound signature, something i like very much. the lab 2 is not the way to go if you want only 1 earphone/headphones, with the jvc i could life if i could ony afford one. for me a top buy for the price, imo better then a lot of higher priced multi ba iem i had that struggles with coherence. you had the lcd2 - the jvc shares a lot with the lcd3f if you know them, very similar overall tuning.
