FiiO BTR15 Bluetooth Receiver & USB DAC Headphone Amplifier This item was purchased new in March of this year and was acquired from the original owner after only a few days of use. It's a highly-rated product, and its functionality and performance are more than satisfactory. However, the previous owner found a model that better suited their preferences and stored this one after only a few uses. Therefore, the total usage period from the time it was unboxed to now is less than two weeks, and it has only been used indoors. It is in near-new condition, with no visible scratches or scuffs. Furthermore, it is fully functional and can be used with complete confidence. Despite its small size, it has enough power to drive high-impedance headphones. It also offers sound quality comparable to wired connections via Bluetooth, making it easy to use with smartphones that lack an earphone jack. This is a recommended model for those considering their first DAC or Bluetooth receiver, or for those looking to upgrade.
