to carry the banner of cost performance, flying proud BTR1K experience evaluation

, under the general trend of canceling the 3.5mm interface, Bluetooth audio equipment is becoming more and more mature, and more stable and reliable Bluetooth earpiece products have also ushered in the update of Bluetooth 5.0. Just a few days ago, Feiao launched an upgraded BTR1K of the explosive Bluetooth Ear BTR1.

time saving, experience point of view is written in the front:

1. The interactive upgrade is convenient.
2. Chip upgrade, Bluetooth 5.0 blessing
3. Have a relatively independent audio architecture.
4. It is effective and cost-effective to improve the audio experience.

Although the price of BTR1K is not high, there are many accessories, which is also the place where Feiao is considerate.

BTR1K body is made of aluminum alloy and plastic, and the body is small. The back clip can be worn with a lanyard or clamped on clothes, which is portable.

, we should know that Feiao BTR1 already has a good reputation, especially its impeccable focus on music functions. In addition to the full selling points of aptX and aptX Low Latency, it also has a function button on the body that is convenient for music operation. This time BTR1K has improved the operation logic of keys. Similar to BTR3 previously evaluated on this site, BTR1K has independent function keys and switch buttons. Although there is one more key, the operation logic is clearer and easier to operate to wake up the voice assistant. The indicator light below is replaced with RGB to display different working states, for example, cyan is AAC, purple is aptX, blue is SBC, and white is USB DAC.

is changed to USB Type-C interface. BTR1K update supports USB DAC function and can be used as a portable sound card.

NFC can be easily paired with other NFC devices. For the simple appeal of audio, NFC can make Bluetooth connection similar to "plug in 3.5mm earphone interface", making pairing more convenient.

chip upgrade, Bluetooth 5.0 blessing

BTR1K upgrades the core to a high-pass QCC3005 chip, supports Bluetooth 5.0, improves Bluetooth signal reception capability, controls power consumption and increases effective transmission efficiency, and upgrades microphone noise reduction to cVc8.0. Qualcomm QCC3005 chip is a highly integrated Bluetooth chip with a dominant frequency of 80MHz and a cache of 64MB. It has a built-in Kalimba DSP data processor and can complete various digital audio and voice processing.

Codec supports SBC, AAC, aptX, and aptX LL. BTR1K can handle most Bluetooth devices. The new chip allows BTR1K to reduce energy consumption while enhancing the signal-to-noise ratio, output power and standby endurance performance.

has a relatively independent audio architecture

BTR1K uses an independent DAC chip in the audio architecture. The chip is AK4376A. This chip supports the highest specification of PCM 32bit 384kHz. The total harmonic distortion reaches THD N =-106dB and the signal-to-noise ratio is 125dB. This chip is commonly used in entry-level music players and HIFI mobile phone products. Feiao used it as a Bluetooth earpiece product, which is still a lot of money.

is effective and cost-effective for improving audio experience.

BTR1K is still the core of this Bluetooth earring. This time Feiao proudly took out the Bluetooth 5.0 for publicity. Both aptX and AAC are indeed more reliable in stability through the actual measurement of this site. Only in this way can the Bluetooth audio experience be more complete.

is different from the sound style of some high-end BTR3. BTR1K has a fresh and bright sound and good resolution, which is also the most intuitive feeling given by BTR1K. Compared with the direct sound of mobile phones, BTR1K will be slightly restrained in style, with stronger control over the sound and darker background of the sound. It can produce better sound when driving some slightly difficult earphone products. BTR1K sound has a certain modification compared to the high frequency of the traditional aptX codec, and the overall hearing is more natural. BTR1K is a special existence. It can make the mobile phone's 3.5mm wired output and Bluetooth sound quality experience by going up one flight of stairs.

In addition, the author tries BTR1K's Bluetooth delay. Using aptX Low Latency in game and video experience can significantly improve the trouble caused by delay. Compared with the high cost of other solutions, BTR1K has achieved this effect with outstanding cost performance, which is very satisfactory.

conclusion: BTR1K is an all-round improvement on BTR1. Although it is a pity for the lack of advanced audio codecs such as LDAC and HWA, this is a product that improves the auditory experience. Compared with other solutions close to the sound quality experience, BTR1K has obvious cost-effective advantages.
