Zhang Feiao BTR1K, who is familiar with "face", has been fully upgraded.

, okay, this time I won't say that Feiao BTR1K is "the 3.5mm earphone connector for retrieving the mobile phone". After all, Feiao has made great achievements in such products, and even this is a fully upgraded version.

, as Feiao's first portable Bluetooth earpiece, Feiao BTR1 is actually good in design, parameters and sound quality. How can all products be limited by the times. In other words, Feiao BTR1 has lagged behind the times in hardware and Bluetooth protocol coding. Under the attack of the new μBTR and BTR3, its competitiveness has become obviously insufficient.

Of course, the Chinese people's consistent "magic change" feeling is also a good way for Feiao BTR1. Do you think this hardware and function have fallen behind the times, so just make a big internal upgrade and make it a flying pride BTR1K that catches up with the times. It's like a round-headed 59 with five pairs of wheels, but there are a lot of modern equipment hidden.

technology is based on changing "flesh"

must first emphasize that Feiao BTR1K does not intend to "squeeze toothpaste" in the way of "technology-based shell replacement". Although it has almost the same skin bag as the previous generation, the upgrade is still very large.

you really don't see much change in appearance from Feiao BTR1K to Feiao BTR1. The visible changes are the change from Micro-USB interface to USB-C interface, and the status indicator from round to long strip. In addition, there is an NFC flag at the bottom, which does not prevent the similarity between the two.

As for the shell, it is still made of aluminum alloy, while the bottom is made of plastic for the convenience of signal transmission. The overall workmanship is still the same as that of the previous generation, and the level is very good. However, if you look at the internal upgrade, you can completely regard Feiao BTR1K as a brand new product with the same appearance as Feiao BTR1.

Feiao BTR1K uses Qualcomm QCC3005 chips, which is a significant improvement over the previous generation of Qualcomm A64215. This chip not only supports Bluetooth 5.0, but also supports Bluetooth audio coding including AAC/SBC/aptX/aptX low latency. Compared with BTR1, which lags slightly behind in hardware, this progress can be said to be a leap forward. In addition to the hardware, it also reduces the bottom noise while increasing the thrust through the optimization algorithm.

As for the high-performance independent DAC carried by Feiao BTR1K, that is, AK4376A, it has also made significant progress compared with the AK4376 adopted by the previous generation. Not only is its output power increased by 5mW and upgraded to 45mW under 16 Ω load, the total harmonic distortion is also slightly lower, and the parameter improvement is still significant.

, in terms of endurance, Feiao has stuffed 205mAh battery into this small body. Although the volume and the absolute value of the battery are not high, this product supports 8 hours of continuous working time and 140 hours of standby time. As for charging, there is no need to worry. After all, Feiao BTR1K also supports "fast charging", which can be filled in only 1.4 hours. If you want to listen to songs with Bluetooth in a hurry, it won't delay too many things.

, as for the long strip indicator light, it is enough to make Mr. Chen, the peripheral expert of ZAEKE Zhike Studio, crazy. The built-in RGB indicator light of Feiao BTR1K can emit more colors and indicate the Bluetooth format coding of the playing track. It can still reduce trouble on the commute without taking out a mobile phone to distinguish the working status.

when talking about Bluetooth calls, a commonplace issue, Feiao BTR1K doesn't even behave like a Hi-Fi product or even has the meaning of humanized mobile phone accessories. It has a built-in all-directional high-sensitivity microphone, and can receive data wirelessly to output stereo audio with an external professional earphone IC. It can also adjust the gain and reduce noise through the eighth generation cVc noise reduction algorithm of high-pass.

In addition to retrieving the functions other than the headset interface, Feiao BTR1K also provides many additional functions. For example, NFC pairing, double-click to wake up the smart assistant, one-click back connection and USB DAC function.

more Hi-Fi "mobile phone accessories"

in Feiao's current portable Bluetooth Hi-Fi earphones, Feiao BTR1K is the one with more "Hi-Fi" relative tuning.

Yes, compared with Feiao BTR3, which pays more attention to "atmosphere", Feiao BTR1K is indeed more bland in tuning. If you pay more attention to the accuracy of sound, then this may be the most worthwhile choice among similar products at present. Or in other words, if you prefer Feiao's old-school tuning style, it does make you feel more appropriate.

, this does not mean that Feiao BTR1K is "plain boiled water" tuning, it is only relatively less in terms of atmosphere-mainly low frequency sense of quantity. If we have to use universal standards to evaluate, it is difficult to say which of these two different styles is better or worse. At best, Cantonese and Sichuanese tend to have different tastes when eating. And if you look at it in another way, users who like pure vocals or light music will definitely prefer a lighter taste.

in terms of hard quality, Feiao BTR1K has obviously improved for mobile phone users. For example, compared with the direct push of the 3.5mm earphone interface of the finger, the details, resolution and separation degree have been significantly improved. Even if you think this statement is somewhat "literary evaluation", I don't think I can hear the "metaphysical concept" such as musical instrument knot or human voice mouth shape several times, but the improvement of the real quality of mobile phones is still obvious.

, however, don't expect it to bring about earth-shaking changes. After all, the function of this kind of portable Hi-Fi Bluetooth earphone still adds a 3.5mm plug to smart phones without earphone holes. It is definitely unrealistic to compare this small-sized earpiece with a professional player, but for most mobile phones, it is no problem to improve the sound quality.

as for the delay that you are most concerned about, listening to songs is definitely not afraid of delay, not afraid of delay in this life. As for video playback, as long as the audio and video synchronization of the streaming media source itself can be ensured, the delay is basically acceptable. As long as you don't have too strong obsessive-compulsive disorder, I think it will be fine. As for the game, don't force it. The delay of FPS game is still obvious. It takes at least 0.5 seconds to hear the gunshot when you press the fire button.

of course, you said that there are some products in the market besides AirPods that can meet the needs of hand tours. I think they basically do not exist. Since it is located in the Hi-Fi market, it is still necessary to take listening to songs as the most important function, and there is no need to worry too much about the delayed performance of hand swimming. After all, on the "basic disc" of music, Feiao BTR1K is still satisfactory.

may be concerned about the difference between Feiao BTR3 and Feiao BTR1K under the premise that the price difference is only 100 yuan. Should we add money or save money?

this question is not difficult to understand. After all, everyone wants to do more with less, but the answer is also very simple. In terms of absolute quality gap, the gap between Feiao BTR1K and Feiao BTR3 is not too big, but the style difference between the two is not small. I like to choose the former quietly and the latter enthusiastically. In addition to sound, the compatibility between workmanship materials and Bluetooth format coding is of course better.

ginger is still old and spicy

For those users who want to listen to songs with their 3.5mm plug headphones, but their mobile phones do not support them, Feiao BTR1K can not only meet their needs, but also have surplus. After all, more professional hardware and more mature tuning make it improve its quality on the basis of ensuring its functions.

Feiao BTR1K is aimed at those who have some pursuit of sound quality. The average user who really hears that the wasteland is old will definitely not pay 298 yuan to buy such a Bluetooth earmuff. Its user group is quite clear. Although it is relatively small, it is even more of a "timely rain" product for those who need it.

Of course, compared with those cheap Bluetooth receivers on the market, Feiao BTR1K has overwhelming advantages in workmanship, compatibility and professionalism, which is almost the only way to upgrade Bluetooth earphones. What you want to know is that Feiao not only has the technical strength of the audio brand, but also has created the relatively complete Bluetooth earpiece product line at present, which is Feiao's most competitive overwhelming advantage in the face of competitors.
