Haha, Bluedio really need to work on how they name their products
it took me a while for their sales representative to explain that to me before I start selling Bluedio, so yeah i can help with the explaination
Bluedio product naming:
For easier understanding, let's call those with "H" as the "H series". The "H series" stands for the "Hurrican", there're three models in this series: H, H+ and H-WH. Forget about the "HT" or "H-" or "H-T" or "H-Turbine", Bluedio named the 57mm drivers as the "Turbine 57mm drivers", there's no such model named Turbine. As for the "Shooting Brake", nobody has any explaination on what the hack that is, it's printed over the top right corner of all models with the Turbine 57mm drivers. So in "H series", H and H+ ONLY!!!!
Example> H

is the same as

Example> H+

Example> H-WH

Difference between H, H+ and H-WH:
H-WH> Wired version, NO BLUETOOTH, easy to understand. NOTE! any Bluedio headphone models with "-WH" means it's with wire, no wireless no Bluetooth.
H> Bluetooth 4.1 with the option to use a 3.5mm wire to connect, built in with 5 EQ mode that you can switch while listening to your music via Bluetooth by pressing the two volume buttons the same time.
H+> Same Bluetooth 4.1 with the option to use a 3.5mm wire to connect, no built in EQ mode, replaced by a MicroSD card slot for music playback (up to 32GB), card reader and built in FM radio.
The "T Series":
"T Series" is the "Foldable" series. There're two models in this series: T2 and T2+. They are the foldable version of H and H+ respectively, same feature, just added the foldable function to make it a little more "carriable". As there's also the so-called "T2S" out there, mind that it's EXACTLY the same as T2.
Example> T2
