I bought these directly from Bajaao.com, and not from Amazon.in (where Bajaao.com was also listed as a seller of this model previously). On the Bajaao.com these were listed as Vertrag BT when I purchased them (now 'BT' has been removed from the listing name). And I checked on the Thonet & Vander website to find that there is indeed a bluetooth version of Vertrag.The product that I received (3 days ago) was Vertrag (the previous version, NOT Vertrag 2.0, & NOT bluetooth). Which is ok by me, as I liked the boxy design of this version better than the angulated look of the 2.0 version. My only complaint is that they charged me almost the same price as the current 2.0 version (Rs 7200 vs Rs7599 listed). Whereas the Swans D1010 MkII is selling for Rs2000 less than D1010 MkIV.I also feel that Bajaao.com have tried to conceal the true MRP & date of manufacture, as the sticker of the authorized Indian distributor Overclockers Zone has been partially removed, so that I cannot see the date of import or price printed on the sticker.The box states that the1 year international warranty can be extended to 3 years for free by registering the product on the Thonet and Vander website. No mention of this fact is made either on Bajaao.com, or on Amazon.in. So I spent an additional Rs1100 to buy a 2 year 'premium' warranty from Bajaao.com.The Thonet & Vander website lists the diameter of the woofer as 4 inches, when in fact it is 3.5 inches (can be easily verified using a ruler). This is blatant FALSE ADVERTISING.The speakers sound good, way better than a cheap Rs1500 2.1 system.If you are planning to purchase these for home studio monitoring, I think they will do ok for beginners. The response seems reasonably flat (but I am no expert). These are NOT real STUDIO monitors.
