Vivo launches metal X6 with 4 GB RAM, and X6 Plus phablet with top-shelf audio chips

Vivo X6
Vivo just lifted the veil off its long-rumored X6 phone, and it turns out that it will have two variations, as is the trend lately - a 5.2" model, and a Vivo X6 Plus phablet with a 5.7" display, covering all bases.
Both phones are set apart from the cutthroat competition by offering 4 GB of RAM, which so far has only been reserved for truly high-end devices, like the Note 5, or outliers like a variation of the Zenfone 2, for instance. Four gigs of the sweet stuff means you can queue and run a ton of different apps at once, without the phone feeling a pinch, though it also depends on the software management and execution, of course.
The value that Vivo added with the larger X6 Plus doesn't end here, though, as it sports the latest high-end ES9028 DAC audio chip for the first time in a mobile phone, an ES9603 amplifier, and a YAMAHA YSS-205X digital surround sound chip, continuing Vivo's legacy as a pioneer in the so-called Hi-Fi sound experience. The X6 also uses a dedicated DAC, though of a slightly lower level - the Asahi Kaisei AK4375A model.
Both handsets offer microSD slots for storage expansion, fingerprint scanners on the back, and will be available in gold, silver, and rose gold metal chassis. Vivo will be shipping them with its own Funtouch OS, plastered over Android 5.1 Lollipop.
How much for the privilege? Well, the dual SIM version of the 5.2" X6 will cost the equivalent of $390 when it is launched December 6th, while the basic X6 Plus would go for $469. If you want the phablet to come with a 4000 mAh battery, you'd have to shell $500, which, at just $30 extra, sounds like a decent tradeoff. Any takers?
