If you buy on Aliexpress, I recommend buying at the Penon or DD-Audio Store stores.
Do yourself a big favor and use Penonaudio, at least you'll get decent aftersale service, should you ever need it...
It sure helped when I was having a ton rose of trouble with Rose Tech IEMs.
I bought my LZ A4 from Penon Audio, back in Nov. or Dec. of 2016 (and they offered me a promotional discount at the time).
During the last year, I've bought other things from them, as well.
So, I was planning to order from Penon, when I'm ready to buy the LZ A5.
