find a beautiful girlfriend for your mobile phone

01mobile phone doesn't have a 3.5mm earphone interface.

[Original of Zhongguancun Online Audio Channel]Feiao released a mini Bluetooth decoding earpiece called BTR1 last year. This small machine has always been my carry-on, for no other reason, just because my iPhone 7 does not have 3.5mmheadphonesinterface, I don't like to use earphones with lightning interface, so I use BTR1 with mobile phone and clip it on my clothes.

this small machine has a microphone and can make phone calls. The cell phone is dead and there is no need to worry that the earphone occupies the charging port and cannot be charged. In short, it feels very practical. Some people may ask why you don't use Bluetooth headsets directly. This question, as an audio editor, I still have some pursuit of sound quality, so I prefer to listen to BTR1 with these good earplugs in my hand, so as not to leave these wired earplugs idle.

However, although the sound quality of BTR1 is good, there is no special bright spot in terms of color value. Actually's small white Bluetooth earpiece looks good, but the sound quality is very ordinary, so the appearance party like me has always hoped that Feiao can produce another small Bluetooth earpiece that can have the sound quality of BTR1 and the beauty of Xiaomi Bluetooth earpiece. I didn't expect Feiao to make it this year. It is the μBTR I have now, which costs 138 yuan. When you see it in kind, you will even have the urge to change into a white mobile phone, because its color value is really not said. However, μBTR is not just a beautiful face. It is a good companion for mobile phones. Let's take a look at the details of this product.

let's talk about the weight of μBTR first. This product weighs only 13 grams. You can almost ignore its weight, so it will never become a burden for you to go out. At the same time, its circumference is 5 × 19 × 9.1mm (excluding back clip), which is basically the same size as your thumb and is one circle smaller than BTR1, so its figure is very petite, and its weight and figure control are very good.

design, μBTR seems to want to compete with these small Bluetooth earphones on the market, especially's little Bluetooth ear holder will compete. The μBTR machine is high-gloss pure white, and the corners are rounded. A transparent plastic plate is attached to the front, making the machine look more crystal clear. However, it is important to remind everyone not to scrape the plastic plate with sharp objects, otherwise it will scrape out lines, after all, it is not high hardness glass. An NFC mark is printed on the plastic board, indicating that μBTR supports NFC function. Below the NFC mark are two hidden red and blue indicator lights, which you cannot see when you are not turned on.

μBTR is equipped with a 3.5mm earphone port on the top of the machine, and the bottom of the machine is a USB TYPE-C charging interface. The operation keys are all set on the right side of the machine body. The microphone hole, multi-function power key and volume addition and subtraction key are arranged from top to bottom. On the back of the fuselage is a white matte back clip, above it is a small lanyard hole, and below it is etched with a proud logo. Feiao carefully printed all the certification marks and product information on the inside of the back clip, which made μBTR look more concise.

The accessory is a USB cable.

μBTR has no accessories, only a USB charging cable. Of course, if your mobile phone also uses USB TYPE-C cable to charge, you can directly use the charging cable of the mobile phone to charge μBTR without having to bring another charging cable.

03who said that good-looking does not require strength?

μBTR looks good, but it is not an embroidered pillow. People have both high color value and real skills. They definitely don't just rely on their faces to eat. In terms of configuration and function, μBTR is equipped with Qualcomm CSR8645 Bluetooth chip, which supports aptX high-quality Bluetooth coding. If your playback terminal also supports aptX, you can enjoy the sound quality close to CD. At the same time, μBTR also built-in a Texas Instruments TPA6132A2 high-performance independent earpiece chip to further ensure the sound quality of playback.

In this evaluation, I used Feiao X7 IIplayer, iPhone X and Sony Xperia XZ Premium phones are used as sound sources and NFC function testers, and earplugs are still matched with Baiya Xie Lantu and qdc Gemini. At the same time, Feiao RC-MMCX1s is also used.headphonesline is used as a portable replacement headphone line.

μBTR is small,drivergeneral earplugs. The standard is basically the same as BTR1. Don't think about big earphones. Big earphones can't handle BTR1, let alone the output power is not as large as BTR1 μBTR. It is for you to build earplugs. The two reference earplugs can basically exert about 70% strength on μBTR. I am very satisfied with this result.

specific sound performance, I think μBTR training is very successful. First of all, the bottom noise control is significantly better than BTR1, and the sound is very clean. Secondly, it has better permeability, especially when matched with moving iron earplugs, it is cleaner and more transparent. The third is that the sound field performance is unexpectedly good. Although it is not particularly wide, it is very regular. It is not cramped horizontally and has a good sense of hierarchy vertically. It is not at all like the sound that a machine in its early 100 s can make. BTR1 has a very good sound field performance, μBTR inherited this glorious family tradition well.

μBTR is very healthy, and the lower set is particularly stable. It is very similar to BTR1 in all aspects. It can be said that the quality is very close to BTR1; but BTR1 has independent DAC blessing after all, and it can still be heard in terms of analytical power. Slightly better than μBTR. In terms of high frequency, μBTR has a thicker line feeling than BTR1 and a little crisper, but its brightness is better than BTR1. The intermediate frequency is almost the same, with excellent density, the vocal position is slightly ahead of BTR1, and the mouth shape is larger. μBTR has a more low-frequency sense than BTR1, which sounds surging, but it is not as clear as BTR1 in layering. Compared with BTR1, the overall sound of μBTR has moved forward a little, and the sense of presence is stronger, and μBTR has a more obvious sound, warmer and thicker, and is more infectious when performing popular music.

μBTR supports NFC pairing

operation part, μBTR has almost no difficulties and slot points. Press the power button for a long time to start the machine. If you continue to press it, the red and blue indicator lights will flash alternately. You can also turn on the NFC function of the playback device and paste the NFC sensing point of μBTR to easily connect. After matching, music is played, and the power key is turned into a play/pause key. Double-clicking the power key will also activate the mobile phone.Voice Assistant. Short press the volume key to adjust the volume, long press to switch between the previous and the next. And the volume of μBTR is independent of the sound source. You can adjust the volume on the playback end and μBTR respectively, so as to obtain finer sound adjustment. For high-sensitivity earplugs, the volume separation function is still very practical. In terms of battery life, the 9-hour continuous playing time has surpassed BTR1, and the charging only takes 1 hour, which is quite fast, so there is no need to worry too much about the power problem.

summary:

a small machine with high color value and good sound like Feiao μBTR, there are really not many competitors on the market, plus the price of over 100 yuan, the cost performance can be said to be quite high. For those who already have HiFi earplugs, μBTR is an artifact that saves you from the bitter sea of mobile phones without a 3.5mm interface. After experience, there is nothing to spit out for μBTR itself. What I want to spit out is Feiao's RC-MMCX1s short earphone line. Although it is a short earphone line, this line is still 60cm long. After installing it, I clip the μBTR neckline. The line feels a little long and is wrapped around my chest. I'm afraid the microphone can't pick up the sound when I make a phone call, which is rather embarrassing. I hope that the big factory of Feiao accessories will do a good job to the end and make a shorter line, which is probably as long as the short-term earphone standard on the walkman wire control before, and it is even better to make it into an ear-winding type.
