That depends. The B2 is the closest I have ever heard a Chinese manufacturer do western tunings. B2 is like Bose tuning. Big mid bassy, warm L shaped sound very moderate upper mids to mid bass ratio. It has a big airy stage to the sound too which helps with all the bass it has. These types of tunings aren't too common nowadays and for some, these will be a welcomed change among the myriads of harmon tuned IEMs we have now.
Harmon tunings seems to be an industry standard now, which is both good and bad at the same time. I will give Shozy some props of going all out on the musical end of the tuning process. No warmth= not Shozy. The only catch on the B2 is that it does require some tinkering to get the sound right for you. What you might hear out of the box may not be anything that you read about them. Burn in, nozzles and cables all play a crucial role into getting them correct. They remind me a bit of the old Sony Z5 in that it is a very colored sound but one that is very enjoyable when you dial in that combo correct. Is it competitive with todays $150 level IEMs? Against more neutral and balanced technical tunings, if thats the type of tunings you like then no. But for folks that love them some big mid bass, warmth and body to your music. It stands out as one only a handfull of IEM options that is using a nicely resolving dynamic with dual magnets with this particular tuning.
Shozy B2 is the one IEM where it actually needs pure silver to counter a bit of that warmth. ISN SC4 shown with the B2.
JVC woodie IEMs comes to mind that are also colored in this way. You can actually say it is unique especially when you consider what is the norm nowadays.
