the FiiO BTR5 2021 with the constant response to changes, TA has already taken on a new look.
[Preface]]
BTR5 2021 (hereinafter referred to as "version 21 BTR5") is not the product of chip supply cut-off after Asahi Kasei's fire, but is a normal replacement. Feiao not only upgraded the core decoding and amplification chip for version 21 BTR5, but also added support for MQA files, increased support for iOS devices and a lot of software and hardware optimization. It can be said that in addition to the appearance, the rest of the software and hardware are basically brand-new.
[Open Package]]
version 21 BTR5 is exactly the same as that of BTR5. The external printing and shell material are made of more sufficient materials and become the same varnish material as the new product. All black background, the bottom of the front is still like a galaxy of blue circuit board lines, the middle is the fuselage outline, the upper left Logo, the upper right double material Hi-Res small gold logo. Logo on the left, model on the right.
, there are Chinese and English bilingual product names, wireless transmission specifications, basic manufacturer information, barcode identification, and a new MQA identification and anti-counterfeiting stickers in the upper right corner.
inner box is the same as before, and the BTR5 body is stuck in the foam.
is an accessory box, a USB C- C, a USB A- C, and a transparent plastic back clip. There is also a small paper box with after-sales folds at the bottom.
- version 21 BTR5 decoding chip has been upgraded from two ES9218PC to two ES9219C chips, and MQA support has been added. The theoretical maximum expansion multiple is 16x. The Bluetooth chip is CSR8675 and Bluetooth version 5.0. It supports the transmission of Bluetooth codes of AAC, SBC, aptX, aptX LL, aptX HD, LDAC and other specifications.
USB chip is XMOS XUF208, which supports UAC 2.0 and 1.0 dual-specification USB DAC. It is switched through in-machine software, but it cannot be recognized by PS5 in UAC 1.0 mode. FPGA precise clock management is adopted with 45.1584MHz and 49.152MHz double crystal oscillator. Built-in 550mAh battery, theoretical working time is about 9H. The 0.49-inch 64 × 32 resolution OLED display is retained. Supports 3.5mm single-ended and 2.5mm balanced analog output, and only 3.5mm single-ended is available when there is a load.
Built-in all-directional high-sensitivity wheat, 3.5mm single-ended compatibility with CTIA standard headset, OMPT standard is not supported, and Ver8.0 cVc noise reduction algorithm is supported for both microphones. Support independent volume of mobile phone, FiiO Control APP control, support car mode. NFC and basic key interface layout are retained.
[Talking Voice]]
version 21 BTR5 is mainly based on steep drop filtering, high gain, DAC frequency division coefficient 1, Bluetooth coding of circulating LDAC specification, and 2.5mm balanced output. In USB DAC mode, UAC 2.0 is selected and output "DSD:ASIO:FiiO ASIO Driver" is selected Foobar2000, and the other settings are consistent with Bluetooth mode.
version 21 BTR5 is more balanced and more relaxed than the old version. The low-frequency sense of weight is obviously weakened and the sense of quantity is reduced, while the deeper dive and rebound speed brings better elasticity, stronger and cleaner low frequencies. The timbre of intermediate frequency and high frequency is also more restored and less dyed, which is somewhat similar to the style of M11 Plus Ltd. The intermediate frequency human voice has a mouth shape and distance of moderate size, and a good degree of separation from the orchestration; high frequency is soft and smooth, delicate and gentle, moderate brightness, and has a certain overtone.
wired connection will bring a fuller three-dimensional image to full-frequency details, and the transient speed will be slightly enhanced. The quality is basically at the same level as the old version. There will be more medium and high frequency details, the separation degree will be slightly improved, and the sound field will be more regular. The sound of version 21 BTR5 is undoubtedly healthier and more natural than the old version, and it is also more omnivorous. In contrast, the old version also has a unique place in interpreting popular voices.
[Make a summary]]
in general, version 21 BTR5 is more suitable for users who want a small device to solve portable wireless audio and mild wired needs. For example, in the process of commuting to the office, the full support of version 21 BTR5 for Bluetooth transmission specifications can fully cope with complex radio environments such as subways, buses, offices, etc., and maintain stable connectivity. After arriving at the office, it can be converted to wired connection. As an external sound card with USB DAC as a PC device, it is an ideal and smooth use scenario transition, plug and play, and completely drive-free. In addition, the support for ASIO drivers provides relatively sufficient room for tossing.
