Since no mods addressed my inquiry as to whether or not these were safe to talk about, talk I will!! **Until advised otherwise of course**
I figure they are safe to talk about since they are clearly not JVC HA-FXT90s. Yes the housing is very similar, but design wise everything else is very different.
As mentioned, these Tingos strongly resemble the FXT90, an iem which I am very familiar with (have two, one more-or-less unused as backup). The plastic used is of good quality and they feel very solid. The rubber strain relief on the housing is quite flexible which came as a surprise.
The cable is similar to those used by KZ, but not nearly as sticky (it's more like the EDse's excellent cable) and a touch thinner above the y-split (about the same as the HDS1, which is thin). Microphonics are pretty poor, but wearing them over-ear is possible and works wonders. Certainly not my favorite cable, but acceptable.
The inline mic and controls are great! Callers say I sound very clear. All three buttons are fully compatible with my HTC One M8 with the +/- ones enabling track skipping.
Now, for the important part. Did you enjoy the sound of the FXT90? Maybe you thought the soundstage was too small, or there was a bit too much midbass. Well rejoice! Tingo maintained the same aggressive signature as the JVCs, but upped the soundstage in a notable way. Ootb I was very pleased with how airy they were. Midbass has also been toned down. It's not necessarily better, but more of a preference change. Other than that their mids, detail, clarity, instrument separation, etc. are all spot on and go head-to-head with the JVCs which are no slouch. These things are awesome for metal and rock, and have just enough bass and warmth to work well with electronic and hip hop.
Also, the stats said the drivers were 7mm. Nah son. They look nigh identical to the FXT90s 5.8mm drivers, so they've got to be around the same size, 6mm at most.
I bought them here but they're no longer available; http://www.aliexpress.com/item/Original-Tingo-High-Quality-Best-Bass-3-5mm-Earphones-Headphones-For-IPhone-Samsung-Xiaomi-MP3-4/32616758390.html
Maybe someone will find them on Taobao or another like site. Either way, I strongly recommend checking them out if you're looking for an aggressive sounding dual driver with a good mic and Android compatible controls. Since my FXH30 doesn't have a mic, these will probably become my go-to daily drivers. So far they're been doing a great job.
