I have a number of final earphones, but personally the model I would like to recommend the most is Heaven II.
The road leading up to my purchase was a bit long; on the online shopping site JustSystems, famous for the all-Japanese word processing software Ichi Taro, they were selling limited numbers of final audio design's BA earphone assembly kit FI-KITB1SS. I already had Heaven V Aging, so I was hesitant to buy this, and then they sold out and I had regrets. I relieved the regret I felt at them being sold out by buying Heaven II, which I considered to be the origin of this assembly kit.
I've also tried other models in the Heaven series; my favorite for sound production is V Aging, while my second favorite is II.
Amongst the models in the series, Heaven II has a flat, versatile flavor; sound definition is good, there are bass tones and they have the same beautiful middle and high tones as other models in the Heaven series. Plus, being priced at less than ¥10,000 makes them the strongest in the series. I personally listen to a wide variety of music, from baroque to EDM and traditional Japanese music, and you can completely enjoy listening to any genre with Heaven II.
People say that the touch noise of the flat cable is a problem, but thinking about it, when you're traveling to and from work or school, you're surrounded by a variety of different noises, and there's no touch noise when you ride a train, so I've gotten so that it doesn't worry me anymore.
On the contrary, I feel that there's more merit in the sturdiness of the flat cable; there's no need to worry about wire breakage even when you wrap the cable casually around ONKYO DAC-HA300, a heavyweight DAP. You can treat it roughly without worrying about it.
I recommend this product to everyone.
