US$143 - US$159 on Penon Audio
The shells were of a medium to large size, with a thin nozzle that is tapered so most users can get a good fit, either deep within the ear canal or just on top of it. It is in a universal custom shape.
The cable is pliable and has low micro phonics.
Price is everything and most audio shoppers want the best bang for their buck. Its easy to see the many portable audio set ups and drool over them and want the best that ones money can buy. An endless merry go round of reading forums, impressions and biting on nails enthuses before each purchase. No one wants to make an incorrect purchase and with many TOTL in ears now over US$1000 which can be out of reach for many budding audiophiles the pool of under US$250 is much larger and more prone to mistake purchases. of course the best option is not only reading but to try before one buys. But I do realize that not everyone has that option which is why reviews can play a part in many peoples purchases.
The Hifi Boy OSV3 is a hybrid earphone with 2 BAs and 1 DD. Popular choices for 2017/2018.
Some were done ok, some bad and some good and excellent.
The Hifi Boy OSV3 falls into the good category, which is why I wanted to try it after hearing good reports from friends.
The OSV3 is a fairly smooth IEM, not offensive in the slightest.
I did find that the bass tightened up considerably after some play time, perhaps allowing the DD to get a bit loosened up. It is solid, smooth and deep.
I enjoyed the V shape sound signature of the OSV3 which is unusual as I am not a big V fan. The smoothness and decent clean mids giving it a bit more naturalness and forgiveness.
The highs/treble are not fully extended which again makes that V shape more palatable, but there is still enough extension and sparkle to please.
generally the OSV3 has more depth to the soundstage than width or height but I did notice a slight variation with different daps.
Daps used: iBasso DX200 with amps 6 & 7, DX120, FiiO M9, Shanling M0 and Hidizs AP80.
