This is my new series of articles - grass, hope everyone support. This series of articles is mainly analyzed through in-depth evaluation, recommending those small and beautiful products for everyone to achieve the purpose of planting grass. In the future, there will be a series of detoxification articles. We will weed the grass, so stay tuned.
During the summer vacation, I started a Xiaomi Bluetooth audio receiver. This product is very cost-effective, but due to the inability to adjust the volume and no built-in microphone, so it is still inconvenient.
When he visited Weibo daily in September, he discovered that FiiO's home had introduced a Bluetooth audio receiver with higher positioning and more powerful functions – the FiiO BTR1. Then I carefully read the introduction, immediately heart, and decisively start one, after a long experience that this product is compared to the millet Bluetooth audio receiver is an advanced step, so just code this Articles to give you all kinds of grass.
â—‡ã€Product Link】:
From the official propaganda of the FiiO BTR1, this is a Bluetooth amp that focuses on the Bluetooth and DAC. The Bluetooth is 4.2 specifications plus the aptX communication technology. The amp chose an independent DAC chip, the AK4376.
This kind of match really shines, aptX improves the transmission rate of the song to ensure the sound quality, independent DAC chip boosts the thrust, and can also be used for the headphones with large impedance, so that the effect is not good.
A few days ago I looked at the flying proud BTR1 there are goods, the results in the near end of this article when it was off. I was very puzzled and asked the store. Their feedback is that they are currently out of stock. After the double eleventh, we can only make drooling drool.
Due to its compact size, the Natural Prototype BTR1 is also simple but natural plastic packaging is still available. This has some effect on the dustproofness of the packaging and whether the inspection product is brand new and unassembled. Because the top of the package is designed with hanging loops, this is more suitable for the racks of large supermarkets.
The back of the package is a simple use of teaching and product-related information, tied to the backpack strap is a good choice.
After removing the outer layer, you can see the fly proud BTR1 lying quietly in the package.
â—‡ã€Family Portrait】: The family portrait of the FiiO BTR1 includes Bluetooth audio receiver, charging cable, anti-lost rope, quick start guide and warranty card.
The appearance of the fly proud BTR1 comparison of materials, the main body using aerospace aluminum processing, in the texture work compared to the plastic surface of the millet Bluetooth receiver is even more upscale. The positive Roman column wave texture increases the color value and enhances the grip.
The back of the FiiO BTR1 is a metal back clip with a FiiO pattern printed at the top, and a small hole reserved at the top of the clip is reserved to prevent losing the rope.
The +-key of the volume is located on the left side of the flying proud BTR1. The keys are not flat raised, but the concave curved surfaces on both sides are high and low, which is easy to press.
In terms of interface, the Fiat BTR1 is left with a Microusb charging input on the bottom and a 3.5mm headphone input on the top.
â—‡ [wearing aspect]:
Compared with the millet Bluetooth audio receiver, the powerful back clip of the flying proud BTR1 is considered to be a kind of large force, but it should be the same in light of its slightly larger size. Because the headphone wire itself is longer, if the fly proud BTR1 clipped to the chest, then there will still be a lot of wire around the left and right, very inconvenient.
Therefore, Fei proud of the use of MMCX connector HIFI headphones, but also intimate design short-line version of the MMCX line. After connecting the FiiO BTR1, the wire can be further shortened to enhance portability. However, since I have not yet purchased such headphones, I have not started this accessory.
First, the key function
Functionality: The Fiat BTR1 has three buttons and two indicators. [Same as Xiaomi Bluetooth Audio Receiver]: Round Button is responsible for turning on and off the machine (press and hold for 2 seconds), enter pairing mode (press and hold for 5 seconds), play pause of the song (click), connect and hang up the phone Break (click).
â— Song Play: Click the function key when the song is paused
â— Song pause: Click the function key when the song is playing
â— Cut next song: long press the volume - key
â— Cut song on a song: long press the volume + key
â— Answer the phone: Click the function key when the call comes
â— Hang up the phone:
[Different from millet Bluetooth audio receiver]: In addition to the previous functions, the round button of the FiiO BTR1 is also responsible for the sound switch (double-click). After the sound is turned on, the button sound indicator (green) will light up and fly proudly. BTR1 adds volume keys on the side to adjust the volume directly. At the same time, the Fiat BTR1 also has a built-in microphone, which makes it easier to connect headphones without a microphone. It is worth mentioning that if the headset comes with a microphone, the FiiO BTR1 will give priority to enable the headset microphone.

Second, the phone connection
When connecting the mobile phone, you only need to select the corresponding product in the Bluetooth settings.

Third, charge life
Compared to the Xiaomi Bluetooth audio receiver, the FiiO BTR1 has significantly increased its battery life to 8 hours. When connected to iPhones and some Android phones, it can also display the current remaining battery capacity. This is also the case with Xiaomi.
The iPhone can display the power, and Android can only display the approximate power.
â—‡ã€Life time】: In order to test the flying squad BTR1's cruising ability, I connected it to the iPhone SE and JVC HA-FXT200 LTD to keep playing at medium volume and turn on the sound mode. The results of the final test are shown in the figure below. Starting at 9:28 in the morning and empty at 15:40 in the afternoon, the battery life is 6 hours and 12 minutes. Considering that the follow-up flight time for the opening of the audio mode will be greatly reduced, the 8-hour promotion will last forever. The time should not be a problem.
â—‡ [Recharging time]: For the charging test, I will connect the Fiji BTR1 to the iPhone SE, and you can see the specific charge changes. After 80 minutes of charging, the indicator will go out (charged). However, the FiiO BTR1 has a minimum of 40% in the low-power display, indicating that there is still room for improvement in interaction with the ios system.
Fourth, penetrating test
Because the official has announced the 10 meters away from the flying proud proud BTR1, I will no longer test, focusing on the penetrating ability of this product. I drew up the plan in my home, placed the front end (Glory V9) on the balcony of the entrance to the house, and used the FiiO BTR1 to walk into a different room and test it.
Judging from the test results, a wall does not have much influence, and the sound can be heard; however, the two walls are somewhat intermittent; the more complex partitions, such as the bathroom, are disconnected. Therefore, it is recommended that you do not penetrate too many partitions when using
First, audio technology
â—‡ [Independent DAC chip]: The FiiO BTR1 is adopted and an independent HIFI DAC chip AK4376 is used. This chip is currently widely used in mobile HiFi, such as the OPPO R11, Nubian Z11, VIVO X7 Plus have adopted this set of chips. However, flying proud BTR1 does not have to be forced to open, but to default this option off, you need to click the middle of the function button to open.
Aptã€aptX lossless Bluetooth transmission technology】:
The FiiO BTR1 adopts Bluetooth 4.2 communication technology and supports audio coding of SBC, AAC, and aptX. These three items are aptX's most powerful.
aptX is an audio coding algorithm that began in the 1980s and is widely used by movie studios and broadcasters. Today, it is more connected with Bluetooth, you can see it on many computers, smart phones, music players. The advantage of aptX lies in the way it transmits music, which can play 16-bit/44.1kHz (maximum transmission bit rate of 576kbps) audio. However, aptX uses a compression method to reduce the audio encoding delay, it can only bring "CD-like sound quality" rather than the real "CD-grade sound quality." However, due to the better aptX encoding algorithm, the sound quality is better than mp3 and acc at the same code rate.
Second, the actual experience
â—‡ [Comparative method]: Use Glory V9 (not aptX mode) contrast Pioneer XDP-300R (aptX mode), headphones for MDR-1A, playback software for seashell music, songs use lossy MP3 and lossless DSD format.
â—‡ã€Compare result】:
However, it is worth noting that aptX requires two-way support, given that there is currently no widespread adoption of aptX in the mobile phone space (known to support aptX with a plus 3T, one plus 5, Huawei nova2, OPPO/VIVO, etc.), if you like With a mobile phone (not aptX), aptX loses its value.
â—‡ [Comparison method]: Use Pioneer XDP-300R, headphone is MDR-1A, playback software is sea bass music, songs use lossy MP3 and lossless DSD format.
â—‡ã€Compare result】:
â—‡ [Contrast]: 1 Use the Pioneer XDP-300R (aptX mode), the headset is MDR-1A, the playback software is Seashell music, and the songs use lossy MP3 and lossless DSD format. 2 Use the Pioneer Glory V9 (not aptX mode), the headset is MDR-1A, the playback software is Seashell music, and the songs use lossy MP3 and lossless DSD format.
â—‡ã€Compare result】:
â—‡ [Comparative method]: 1 In both use Pioneer XDP-300R (aptX mode), the headset is MDR-1A, the playback software is Seashell music, and the songs use lossy MP3 and lossless DSD format. 2 Use the Pioneer Glory V9 (not aptX mode), the headset is MDR-1A, the playback software is Seashell music, and the songs use lossy MP3 and lossless DSD format.
â—‡ã€Compare result】:
———————————Comparison Summary———————————
1. aptX compared to ordinary Bluetooth, the gap in the MP3 format music is limited, but for the higher specifications of DSD format music is different.
2. aptX compared to direct connection, MP3 format format can not hear the difference blind, DSD format vocal loss details, the sound field drops.
3. After the Fiji BTR1 sound effect is turned on, the sound field expands and the position of the vocal changes. However, in the MP3 mode, the sound source is easily exposed, which is more suitable for enjoying in the DSD format.
4. Flying proud BTR1 (sound effect off) compared to millet Bluetooth audio receiver, in the MP3 format, whether it is aptX or ordinary Bluetooth are no obvious differences, but after the sound is turned on, fly proud BTR1 in the details of the processing will be more in place The overall sound field has improved.
First, the advantages and disadvantages
1. Advantage
(1) The Fiji BTR1 is more concerned about the use of materials. Compared to plastic materials, the Roman column wave texture of aluminum alloy brings a sense of improvement to the product.
(2) In the more powerful function design, compared with the Xiaomi Bluetooth audio receiver that only cut songs, play pause, and hang up the phone, the fly proud BTR1 also designed a volume adjustment key, built-in microphone and independent DAC chip, which can be used by consumers. Bring more user-friendly operating experience.
(3) With respect to the sound quality experience of the Fiat BTR1, aptX's technical blessing can bring a greater bit rate for music transmission, thereby improving the sound performance. At the same time, the sound mode under the independent DAC chip (AK4376) enhances the front-end thrust, making the connected headphones have a certain extension on the tri-band, and the details are reflected.
(4) In terms of battery life, 2 hours of charging and 8 hours of battery life have greatly improved the use experience of the FiiO BTR1, especially for the commuter use of half an hour in the morning and evening.
2. Insufficient (1) The aptX technology's blessing for the FiiO BTR1 does not appear to be as loud as a stand-alone DAC, and the recognisability of the human ear is relatively limited.
(2) The anti-lost rope that comes with the flying proud ATR BTR1 is slightly tasteless. After being tied up for a long time, it is easy to wind up with the headphone cord, and at the same time, the clothes should be hung on the neck.
(3) The fly proud BTR1 lacks the fast-forward and fast-rewind functions on the key operation. Although it is relatively unpopular, it is still useful to consumers. It is recommended to change the song to double-click on the volume button, and change fast forward and rewind to long press.
(4) The Fiji BTR1 has the lowest power display in the ios system at only 40% (in fact, it is empty), so there is room for improvement in the display.
Second, evaluation summary
As a Bluetooth audio receiver, the FiiO BTR1 impressed me with its exquisite appearance and strong performance. However, there are certain limitations in the use of this product, especially the two-way support of aptX technology, and the MP3 format has little difference. It is hoped that Feiao Company will be able to introduce newer and more powerful audio devices to consumers, so that we can also enjoy the pleasure brought by the sound quality.
The last thing is to replenish it as soon as possible. My buddies watched my flying proud BTR1 are hungry and thirsty. This assessment is over. I'm Geek Research, a hobby graduate student.
