Let the active speaker fly, make the car stereo hard, Feiao BTR5 Bluetooth HiFi decoding evaluation

to me, Feiao BTR5 is a late professional Bluetooth HiFi decoding earpiece, because I just bought a BTR3 for GL8 at the beginning of the year to solve the bad Bluetooth listening experience of car machine. Every time you get on the bus, you manually turn on BTR3, and then it will automatically connect to the vivo NEX mobile phone. It is LDAC codec, so the sound quality is better than the Bluetooth of the original car system. However, the new BTR5 is a warm integrated car mode. After the car is powered on, it will automatically turn on the car. When the car is turned off, it can automatically turn off the car. It does not need to worry about it at ordinary times. The experience is like the car machine's own system, and there is no feeling of "patch" psychologically. Based on this alone, BTR3 has no choice but to retire.

car mode is actually not complicated. When the car is powered on, the cigarette lighter or USB port will start to supply power. With current, it will automatically turn on through BTR5, and then automatically connect devices such as mobile phones. When the car is powered off, the cigarette lighter and USB port will also be powered off together. The USB port of some new energy vehicles will be powered off after 5 minutes, and BTR5 will be automatically shut down if the current is lost.

also has two advantages that the previous BTR3 did not have. For example, the new BTR5 has its own display screen. Although it is only 0.49 inches and is a monochrome OLED with a resolution of only 64 × 32 pixels, it is still much better than BTR3, at least it can see the Bluetooth connection format intuitively. In the past, every time I changed my mobile phone on BTR3, I always found out what format the color of the indicator light represented in the manual. Now I don't have to bother. And the remaining battery power, volume, filter mode, etc. can also be displayed.

knows that there are many devices with good sound quality in LDAC format, but compatibility is sometimes average. It is really embarrassing to use when the connection between mobile phone and Bluetooth decoding is unstable. What is even more embarrassing is that there is no solution. There is little possibility of providing Bluetooth transmission format selection on the mobile phone, and the same is true for most receiving devices. For example, BTR3, I have encountered this problem, so I feel deeply, and the final solution is to change the mobile phone. However, when it comes to BTR5, there is no need to be so sad. After connecting BTR5 through Feiao Music APP, you can choose which Bluetooth codec format to use, and you can force a certain format to use. For example, LDAC is unstable, then I can cancel the LDAC mode and only allow either AAC or aptX. At present, it seems that only the Feiao family can decode Bluetooth HiFi so professionally.

of course, more people buy Bluetooth HiFi decoding may be to connect wired earphones. After all, mobile phones like to follow suit. When Apple canceled the 3.5mm earphone interface, a large number of mobile phone manufacturers immediately canceled the earphone mouth without any brain, as if keeping the earphone mouth would expose their mobile phones. Perhaps most mobile phone manufacturers will follow Apple's example in carrying an earphone patch cord in random accessories, but the sound quality of that thing is really not good, so users who have certain requirements for sound quality often choose to spend extra money on a high-quality Bluetooth HiFi decoding earpiece.

, there are also some old players who bought a lot of thousands of yuan or even tens of thousands of active bookshelf speakers many years ago. With the advent of the intelligent and wireless era, the startup frequency of these old antiques is getting lower and lower, and it may not take three or five times a year and a half. At ordinary times, in order to facilitate more time, choose to use smart speakers with flat sound quality, such as Xiao Ai, to listen to music. In fact, it is a waste, wasting one's own time, and even wasting the quality bookshelf speakers in one's hand. It is also easy to "bring these speakers back to life". A Bluetooth HiFi decoding ear can solve it. After all, it is an active speaker, so there is no requirement for input power, as long as the sound quality is good. I used BTR to connect hivi X5 at the earliest, and the effect was very good. The mobile phone controls music playback and can operate like an ordinary Bluetooth speaker. The wired speaker has finally become a wireless speaker and is also a high-quality wireless speaker.

the above are all my personal experiences and experiences. Now I say back to Feiao BTR5. The volume of the host is slightly larger than BTR3, 72 × 32 × 11(mm), and the weight is only 43g. It uses a high-pass CSR8675 Bluetooth decoding chip, supports up to 24bit audio signal processing, and has built-in two ES9218P digital-to-analog conversion chips and XMOS XUF208 USB decoding chip. When using Type-C to connect PC computers, PCM decoding up to 384KHz and hardware decoding in DSD format are also supported.

BTR5 supports rich Bluetooth formats, including SBC, AAC, aptX, aptX-Low Latency, aptX-HD, LDAC, and is Bluetooth 5.0 NFC. The stability of signal transmission and the convenience of pairing connection are not to be said. BTR5 also draws on the FPGA design of traditional HiFi player to manage Bluetooth audio signal, clock and USB audio signal in a unified way, thus solving the problem of clock homology between modules. According to the official introduction, under LDAC codec, BTR5's Bluetooth audio index has reached the level of local playback. It is no wonder that the sound quality when connecting NEX 3 5G is almost impeccable.

is a pair of earphones with wheat wire control in accordance with CTIA design specifications, when plugged into BTR5, the microphone that works during the call will automatically switch to the earphone wire control, so that the sound control effect is better. After all, the distance between the wire control and the mouth is closer, and the sound control effect is better. However, if a pair of wheat-free earphones is inserted, or a wheat-equipped earphone that does not meet CTIA standards, then BTR5 's own dual microphone will be used. Because cVc noise reduction algorithm is supported, the call effect of BTR5 is very clear.

BTR5 comes with a transparent shell when it leaves the factory, and its main function is to use it on the bag or clothes. The middle frame of the main machine is made of aluminum alloy, the front and rear panels are curved glass, the surface is added with an oleophobic layer, and the touch of the fingers is very smooth. However, the anti-fingerprint ability is general, and it is easier to leave finger marks on it. Fortunately, it is easy to clean up, and wet cloth or paper towel can be gently wiped.

BTR5 has a built-in 550mAh lithium battery, and the battery life of Bluetooth decoding can reach 9 hours. The battery is not large, so the charging time is short, and it only takes 1.5 hours to charge 500mA low current. Although small in size, BTR5 also supports dual-port output: standard 3.5mm single-port and 2.5mm balance port. The single port is suitable for headphones or other audio input devices with impedance between 16-100 ohms, while the balance port is suitable for headphones or other audio input devices with impedance between 10-150 ohms. At 16 ohm impedance, BTR5 has a maximum single-port output power of 90mW and a maximum balanced port output power of 240mW. When connected to a PC computer, BTR5 can decode up to 32bit/384KHz PCM audio and DSD audio of DSD64/DSD128/DSD256 specifications.

there is no harm if there is no comparison. Compared with BTR, BTR5 has better sound quality than M6. I even think it is better than M6. Even LDAC's wireless Bluetooth sound quality, details and dynamics are available, and the high frequency is much softer, unlike the first generation BTR. In the past half a year, Feiao's tuning has changed a lot. The player pursues balance and the headset pays attention to accuracy. This can also be felt on BTR5.

BTR5 has two levels of gain adjustment. When connecting active speakers and on-board AUX, it is recommended to use high gain. The difference is quite large. At low gain, I feel that the thrust is not enough and the sound is not open, like a layer of yarn. At high gain, the sound is flesh and blood, the low frequency has been greatly enhanced, and the sense of quality will be immediately available. However, I also tried some headphones with high sensitivity, such as Andromeda. The sound is a little messy after high gain, but the sound is very accurate at low gain and the control performance is better. However, after PX200 is connected, the high-gain sound is fuller and the low-frequency sound is more surging.

I didn't try EQ or something, after all, the adjustment of gain can already meet the use requirements of different products. There is also the choice of filter. Although there are many options, such as short delay descent, apodization filtering, hybrid steep descent, rectangular filtering, etc., I'm sorry I can't hear the difference. Only at the moment of change, the sound dithered, and then there is no feeling, it seems to be the same.

this is the first Bluetooth HiFi decoding earpiece that I have used, although it is wireless audio, but it is very close to local playback quality. It can be said that there is no competitor in the same size. Of course, its price is also very beautiful, which is twice as expensive as BTR3. If you care about the sound quality, you can consider it. If you want to bring the old speaker back to life or solve the most basic quality problem of Bluetooth in your car. BTR3 can also meet the general use requirements.
