[Dual "Core" Drive, Balanced Output] Feiao BTR3K Bluetooth Earrator Experience Sharing

Feiao's BTR series Bluetooth decoding earphones have had good sales and reputation since their launch. Among them, the launch of Feiao BTR3 is a landmark product. It not only changes the traditional appearance, but also adopts Qualcomm CSR 8675 Bluetooth master control and supports LDAC encoding, which makes Bluetooth decoding earpiece turn on lossless transmission. As an upgraded product of BTR3, BTR3K maintains the original design appearance and configuration. The upgrade adds two DAC--AK4377A and 22.5792M/24.576M double crystal oscillators, with 3.5mm single-ended and 2.5mm balanced dual-interface outputs, and is once again in the forefront of similar products at present.

Appearance & Configuration

BTR3K and BTR3 have the same appearance, with a volume of 58 × 25 × 11(mm) and a weight of only 23.5g. The pure black body, aluminum alloy frame + double-sided 2.5D glass are perfectly combined, and the metal texture corresponds to the black high-brightness glass. It is more like a handicraft, which is silky and warm in hand.

can be easily carried out and a lanyard is given. However, the body volume of the back clip is much larger after being installed. It would be better if a lanyard hole could be directly reserved in the fuselage to wear.

BTR3K is a colorful breathing light. Different colors are displayed under different Bluetooth codes, and the whole machine looks more elegant when lit. When Bluetooth is connected, it is in the breathing state, and the USB DAC is in the white always on state. In addition, you can also use app to turn off the led light to save power.

, the on key, mic, function key, and volume key are in order.

BTR3K with full pointingmicrophoneand control functions, support the 8th generation CVC call noise reduction technology, the measured call effect is not bad, a little hands-free feeling, the sound is quite clear.

can also wake up the voice assistant of the mobile phone. However, switching songs requires a long press of the volume key, which is not as convenient as double-clicking.

BTR3K uses the mainstream Type C interface, which supports listening while charging. After a few days of use, it is actually full for more than 1 hour, and the non-continuous work has reached more than 10 hours. For the built-in 330mAh battery, the battery life is ideal, meeting the needs of going out during the day.

BTR3K adds a 2.5mm balanced output port, which is also a major selling point of this upgrade. B should be able to attract the attention of many burning friends, and the back of the fuselage is equipped with Dafa HI-Res small gold logo, brain certification points!

Highlights & Feelings

1. "Lossless" Bluetooth + "Dual-Core" Decoding:

BTR3K has built-in Qualcomm flagship chip CSR8675, Bluetooth 5.0 version, and supports Bluetooth encoding such as LDAC/aptX HD. CD-level quality has been achieved. Built-in two DAC--AK4377A, two 22.5792M/24.576M crystal oscillators, decoding output has reliable hardware guarantee.

has tested IOS devices, Apple 8P and ipad pro, and Bluetooth transmission can only be SBC.

The Android device is Redmi K30, and the transmission protocol is LDAC.

stability: There has been no interruption at present, even if LDAC is used indoors for a distance of five or six meters. However, after connecting two mobile phones at the same time, K30 cannot play normally as long as ios has sound output. It is all noisy. It needs to restart APP or disconnect IOS Bluetooth to restore it. It is estimated that it is a bug.

power consumption: LDAC does consume more power than SBC transmission, but the difference is not particularly large. It is roughly estimated that the power consumption will be 1% ~ 2% more in about half an hour. If it is not used continuously, it can be ignored.

sound loss: compared with the iPhone8P under the patch cord in the bluetooth state, it can only be said that the wire has greater thrust and does not have much direct feeling. although it is SBC transmission, it is possible that apple's patch cord is also a USB DAC, but it is not to enhance the sound quality in order to solve the problem that the mobile phone does not have a 3.5mm earphone socket. if your apple is still using the original patch cord, I, of course, there must be a big gap compared to decoding lines like takt. Using LDAC connection under K30 is also not much different from in-line sound.

2. Balanced and single-ended "dual output":

BTR3K has 3.5mm single-ended and 2.5mm balanced dual-interface outputs. Whether it is single-ended or balanced, it works with dual DACs. When balancing the output, the two DACs will be responsible for the left and right channels respectively. The total power can reach 78mW. The single port can reach 50mW of total output power under 16 ohm impedance, which is enough to push most earphones.

because there is no money to burn, there is nothing hard to push. It is matched with sony n3ap, Meizu live 15th Anniversary Limit and Wessonik GR09, which are three earplugs that I carry with me in daily life. These earplugs are all very popular omnivorous plugs within 2,000 yuan. The original quality of single-ended lower earplugs can be expressed. BTR3K has a small sound field and some tight feeling. The sound is relatively high-frequency, low-frequency is relatively weak, and, not radical. After changing to the balance line, the thrust is indeed greater, and the sound density, separation, atmosphere and presentation of details are enhanced at the same volume. Moving iron headphones like live are fine. N3ap and gr09 immediately feel mixed and stuffy when they change back to the single end. It takes a long time to adapt. It is also easy to change from frugality to extravagance, and it is difficult to change from extravagance to frugality.

single-ended and balanced headphones are plugged in at the same time, the machine will stop output. It is estimated that it is to protect the circuit from overload. If simultaneous output is supported, it is still very suitable for good friends to listen to songs and make machines together.

3. USB DAC PC, Android plug-and-play, and ios devices are also supported:

BTR3K can be directly recognized under Android, windows and mac, but it cannot automatically identify the device under Android to judge the power supply, so it is necessary to enter app to turn off the charging function. IOS requires a camera kit and cannot be directly connected like Q1mk2, and it is not allowed to use Q1 L to M plus TYPE-C adapter.

found an unreasonable place in use, that is, the volume of USB DAC and the volume of Bluetooth connection cannot be independent. Generally, I adjust the volume of BTR3K to the maximum to meet the thrust. However, when connecting USB DAC, the output of the computer is much larger than that of Bluetooth, and the sudden high volume almost didn't take me away.

4. Supporting APP, controllable and adjustable

Feiao BTR3K can be set using Feiao Music FiiOMusic. Feiao Music is relatively simple, but it does not support nas very well, so Haibei music and foobar2000 are often used. There is also the single-ended control APP FiiO Control separated from Feiao Music, which supports Android and IOS. Functionally, the Android version of Feiao Music may have some small settings. Generally speaking, IOS can also fully experience the main functions.

Through FiiO Control, you can make some basic settings for BTR3K, debug your favorite EQ, input your earphone parameters to estimate the approximate output parameters, and finally detailed operation instructions. Generally speaking, some small settings increase the playability of BTR3K, adding to the icing on the cake but nothing special.

Comparison with μBTR and Q1 MarkII

μBTR is very small and supports aptx and nfc, Qualcomm's CSR8645 + TI Texas Instruments TPA6132headphone amplifierThe solution is extremely cost-effective.

If you don't download the lossless audio source by yourself, but only use the mainstream music APP, you can completely use it.

BTR3K is compared with μBTR, it is not a level at all. Except for canceling the uncommon NFC, the hardware is almost crushed. Sound quality is also a gap that can be recognized by one ear. Before listening to BTR3K, I always thought it was like iPhoneBluetoothprotocol is similar with dozens or hundreds of Bluetooth earphones, ignoring the decoding function of DAC. For students who have the same idea, I recommend you to upgrade.

Q1 MarkII is also one of the devices I often use. With mifi certification, it can be directly connected to iPhone. It is convenient and has the same color value and cost performance. The sound of BTR3K and Q1 MarkII are smaller than the sound field, the sound is still a little thin, the analytical force and the degree of separation are quite different, and the overall sound orientation is almost the same, which is more audible. After all, the positioning is different, the volume is different, and the price is different. The main advantages of BTR3K are compact and portable and Bluetooth function. Of course, it would be better if it supports ios wired direct connection.

summary

BTR3K maintains Feiao's consistent fine workmanship and high color value design. It is small in size and supports aptX HD and LDAC lossless Bluetooth coding to ensure sound source transmission. The dual DAC/dual crystal oscillator/dual output design is sufficient to enable most plugs to introduce their due quality. Android and PC drive-free USB DAC are very convenient. As for dual-computer connection, APP control also increases its playability, this price can be experienced on the compact Bluetooth decoding earpiece to balance the output can be said to be very cost-effective. BTR3K can make the stopper eat less ash. It is a good choice for students who still have some pursuit of sound quality and have not compromised TWS.
