Guys help.!! Is it OK to buy unboxed iem?

Guys I'm planning to try my first iem and i am a bass lover shifting from oneplus buds 3. Tangzu and kz duonic was my first choices but they are out of stock since 2 weeks.

Is it ok to buy unboxed tangzu wan'er sg 2 red lion if unboxed variant comes in stock??

Whats the condition of the unboxed one?

And there is barely 300 rs difference between new n unboxed one whenever they are available.

Should i go with unboxed or wait for new.
