Hmm.... my version directly from XiaoMi store (purchased on 6th Jan) is: details: S/M/L on tips case, ribbed R on strain relief verdict: hard hitting bass, extended treble (I only have one version, treble is extended. I can't say it is recessed).

  I bought my Piston II directly from Xiaomi PRC website and it has internal raised S, M and L characters in the box.

For Havi Pro (old version), I had spoken to them and told him that it is popular on here. They capitalise on that and reproduce the current batch. I order 2 set for myself and I would believe they have around 50units for current batch, as I asked him how many does he have. He only replied that...

Hi,   Here are some of the TB review comments I extracted from Don Scorpio Dolphin and Drama headphone. However, there ain't much comment on DRAMA.   >>>>>>>>>>>>>> 适合听真人发声/清音乐，不适合重音乐/摇滚等类型，好评。 Suitable for live vocal or sparse instrument music. Not appropriate for heavy, orchestra, rock...

  I was looking for some reviews on Dong Scorpio Bass IEM and found someone who bothered to write more. Rest are mixed short comments of average and value for money IEM. Nevertheless, there is short review which I tried my best to translate:   <...

        ah.. cool... I was taking reference to their Havi B3 Old Pro TaoBao price as I am able to purchase directly. Just paid for 2 sets :) Nevertheless, the price on Penon Audio came out to be cheaper and more cost effective for everybody. Thanks!

  The price for relaunch old Pro version is US$11.50 more than existing Pro in TaoBao, and I am not happy about it :( Looks like he got greedy? Or it requires more effort to produce the old Pro?   Quantity wise, it seems that there are quite few 10s units from what I gathered.

That's for the day, guys and I be heading to bed now. I will post up some feedback if Havi will put up a sticker to double indentify the old version when I hear from them again. Cheers!   BTW, You may probably want to stress on the words "旧版pro" in your order via a purchasing agent.

Sorry that I do not have both to compare and you will have to refer to bhazard review. From Havi, the guy said that Pro II has enhancement on the low, mid and high etc to appeal to the mass market, younger crowds.   Below are the direct words from them, probably need google translation:  ...

  Yes, I just read the message from them sent 2 days back. They said it will be available on 20th/21st Feb. Not sure what marking they have done now, but I just feedback to them to put a sticker tag "旧版pro" or "First Pro" version to indicate it is the former pro version. So it won't be any...

  Well...little interest in this, so I guess I just let it die off unless there is a definite interest of more than 10 units.

Hi,   Pardon me that I am new and this is my first post despite being an on-off reader of head-fi for many moons.   I had some chat with Havi B3 seller, and gathered some infos which I like to share below. Before that, I have some questions:   bhazard, like to check with you when and where...
