Description

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.

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.

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.

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.

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.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $33 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for FiiO products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
