Fiio sells products in about a dozen categories, but it's the brand's budget DACs and IEMs that contribute to its bottom line in a meaningful way. There has been a lot of excitement in this area in recent months, with Fiio launching a lot of new models in its dongle DAC range, and the brand is now focusing on its Bluetooth offerings.
While the KA11 and KA13 do a great job delivering a clean sound in a tiny chassis, they need to be plugged in — you don't get Bluetooth connectivity. Thankfully, the brand has the BTR5 and BTR7 if you want Bluetooth DACs, and both are highly regarded; I use the BTR7 extensively. And now, there's a new entrant in this segment: the BTR15.
