The technical specs of OnePlus' X look very similar to that of the One at first glance. However, some differences are found in the details. The review sample is only available with 16 GB of internal storage, but it can be expanded via a micro-SD card. The buyer could only choose between a 16 and 64 GB model for the Chinese manufacturer's first handset; only the latter is still available. The premium models generally do not allow expanding the storage. Besides that, the One features the fastest Snapdragon 801 while the X model can fall back on an 801 AA with an identical speed as the former Snapdragon 800. The review sample is currently priced at 269 Euros (~$291) plus shipping in the manufacturer's online shop.

We looked at smartphones in a similar price and size range for comparison devices. Sony's Xperia M4 Aqua, Microsoft's Lumia 640 and LG's G3 are among them. The latter is a high-end product from last year that is now on a comparable price level, and which has a similar SoC. LG's Flex 2 is also now sold for under 300 Euros (~$324).
