The F1 is surprisingly one of the best vocal centric earphones I've ever heard with excellent details and instrument separation. Bass is light but has enough details to make it not be anemic like other mid centered earphones.
The presentation is quite pleasant opening the box to see the way they're displayed. KB ear may be a newcomer to the game but I was immediately impressed with a great looking thin but quality feeling stock cable, unusual in most earphones around this price range.
Specs
22-ohms , 20-20KHz , 105 db@ 10mW , MMCX cable with 3.5 termination
This is IEM may look unusual but it handles vocals and acoustic music exceptionally and I would definitely recommend it for it's intended purpose.
