Product code: FiiO offers BTR3K Receiver Amplifier Bluetooth Headphone Amp High Resolution
Building off the what made the offers BTR3 so good, the BTR3K implements balanced output. It is a truly balanced design, with a DAC and amplifier carefully paired for the left and right channels each, for the purest sound possible. I paid over $80 for this. I'll take $50. Never used. Phone used in the Amazon picture is not included as pictured in the 3rd pic.
