Specification AgeRangeDescription : Adult AmplifierType : Operational AudioDriverType : dynamic_driver BatteriesIncluded : 1 BatteriesRequired : 1 BluetoothVersion : 5.4 Brand : FiiO BulletPoint1 : Equipped with Qualcomm's new-generation flagship Bluetooth chip, the QCC5181, the UTWS5 2025 supports Bluetooth 5.4, complies with the LE Audio standard, and offers a bandwidth transmission capability of up to 2.1Mbps. It also supports the Lossless specification in the aptX Adaptive system, as well as audio codecs like LDAC and aptX Adaptive at 96kHz/24bit. BulletPoint10 : 84 x 40 x 16mm / 75g BulletPoint2 : When enabling desktop mode and using the BTR17 to connect to a smartphone as a tail DAC/amp, you can connect the dedicated power input to an adapter. In this case, the battery will be fully powered by USB, preventing overcharging and overdischarging. The device also delivers a powerful 650mW output capability while not consuming the smartphone's battery. BulletPoint3 : With lower latency, more stable transmission, and better compatibility than regular USB chips, the device supports 768kHz/32bit, hardware decoding for DSD512, and full MQA decoding. It also features PEQ developed on this platform, allowing adjustments via both the app and web interface, with support for high-definition PEQ at a sampling rate of up to 192kHz. BulletPoint4 : The BTR17 is equipped with two ESS flagship dual-channel DACs, the ES9069Q, based on the fourth-generation 32-bit HyperStream architecture. This allows for enhanced performance and lower power consumption. Additionally, it further reduces digital noise within the DAC, achieving a dynamic range of 130dB and total harmonic distortion of -120dB. The result is a richer musical experience with a purer sound background. BulletPoint5 : The BTR17 features a convenient and user-friendly three-mode switch (PC/BT/PHONE), allowing for seamless one-click switching between computer soundcard, Bluetooth DAC/amp, and smartphone tail DAC/amp modes. It automatically optimizes the power supply status based on the connected front-end device, offering versatile usage and greater peace of mind. BulletPoint6 : 【Car Mode】W3 Bluetooth dac will power on with the car and connect with smartphone automatically. BulletPoint7 : 20-band Double Precision PEQ/GEQ BulletPoint8 : Two High Sensitivity MEMS Microphones BulletPoint9 : PC Chrome App Windows/macOS/Linux & Android Mobile App. *iOS App not available.
