So I finally got my FH5s in today. Been listening to them on and off all day today and I think I know why HBB took the screen off of the front nozzle. I haven't done that myself but overall I am impressed with the FH5 as they are. However I took some liberties of doing a few things to make them even better for me.
I threw on a pure silver cable on my IT04 and those now sound even better than with the stock cable which is actually a very nice cable in itself. The cable that came on the IT04 cost $100 so why waste a great cable right?
Sacrilege! I threw on the CB12 cable on the FH5. What you know, now we are cookin with a wider stage and even better imaging. I suppose you have to be a believer in cables to know what I am talking about but it does make a difference.
These sound great for the money and they exhibit a smooth slightly vocal forward, musical yet detailed character, well balanced and I can tell Fiio paid particular attention to the treble end of these to not fatigue.
For those that are curious these sound great using a balanced source and balanced cable by the way. Better than single ended. Could be due to having more juice in balanced mode but they sound more dynamic to me in balanced vs single ended.
I know there are more than a few guys wondering of the FH5 in a similar configuration can come close to Ibasso's flagship earphones. I will just say No. The IT04 has a higher end tuning on them. Balancing is better on the IT04 and is a more refined sound vs the FH5. However this does not take away how good the FH5 is. IT04 don't sound twice as good as the FH5 but twice the amount of money is the going rate for more refinements in the sound game.
I haven't heard the FH5 long enough to have a conclusive view on their sound but I did enjoy listening to them today. Will have more to say about them as I get to know my FH5.
