to get rid of the shackles of wired HiFi earphones, Feiao UTWS3 real wireless Bluetooth earphones

Although HiFi music players and earphones are the main product lines that Feiao has spent in recent years, as a "hard core" brand in product technology, Feiao often brings some special products to consumers. They may have strong playability, such as the BTA30 previously evaluated; or they can directly hit some "pain points" of HiFi players and provide more diverse solutions for their "playing machine" life. The UTWS3 I want to experience today belongs to the latter.

Feiao's definition of UTWS3 is "true wireless bluetooth headset power amplifier", which gives the earpiece products the hottest "true wireless" keyword in the past two years. UTWS3 already has enough to attract consumers' attention. In short, UTWS3 is specially designed for wired headphones. By connecting with it, wired headphones can also become true wireless headphones. Of course, the difference with ordinary Bluetooth earphones with wired earphones is that it is suitable for interchangeable earphones. The earphone unit "loses" the earphone cable and is directly connected to UTWS3. At present, UTWS3 provides versions of MMCX and 0.78mm interfaces. Users can choose according to the interface used in the interchangeable earphone. MC is evaluating MMCX version this time.

From the appearance, UTWS3 is a pair of earphones without earphone units. After the earphone units are connected, it becomes a pair of earphone real wireless earphones. Its design can be divided into two parts. The front half of the earring is memory metal, wrapped with soft silicone material, which has a delicate touch and can be bent to a large extent. The second half is a plastic cavity, which includes various components.

Bluetooth chip part UTWS3 adopts Qualcomm QCC3020 chip, which is based on Bluetooth 5.0 standard and supports Qualcomm TWS dual-channel transmission. There is no longer a main and auxiliary earphone. The two earphones can be used at the same time or either alone. In terms of Bluetooth encoding format, UTWS3 provides support for aptX, AAC and SBC, which can meet the needs of most people on Apple or Android phones. The Bluetooth wireless terminal has Qualcomm chip "escort", and other parts also have "master" assistance.

Feiao has designed an independent ear amplifier architecture TPA6140A2 for UTWS3. Compared with the integrated amplifier circuits mostly used in similar products, UTWS3 can provide stronger thrust and better noise suppression. At the same time, in order to ensure the lossless transmission of audio signals, the audio line inside UTWS3 is also made of high purity single crystal copper and silver plated material. UTWS3 can also make up for the call function that HiFi wired headphones do not have. Two high-sensitivity microphones are built into the left and right earrings-the main wheat at the bottom picks up the voice of the call, and the secondary wheat at the middle picks up the ambient noise, which is filtered out by Qualcomm's double wheat CVC noise reduction technology award.

Feiao has equipped UTWS3 with a charging box. Compared with ordinary real wireless headphones, UTWS3 's charging box is larger. First, its own ear-mounted design takes up more space. Second, Feiao specially adopts a large inner cavity design on the charging box to accommodate more sizes of earphone heads and UTWS3 at the same time. UTWS3 itself can have a battery life of 5.5 hours. The charging box has a built-in 800mAh battery, which can be charged through the USB-C interface and can provide UTWS3 with 4-5 charging times. The total battery life can reach 30 hours, which can meet the needs of most people for a week. No problem.

For real wireless headphones, wearing comfort and stability are very important. I connected FD5 to UTWS3 and felt it. The UTWS3 ear-mounted structure has a great blessing for wearing stability, making me feel more stable than many real wireless headphones I have experienced before. I also specially experienced it under the condition of fast walking exercise. The overall performance of UTWS3 can be said to be "stable". Even if there is a large amount of head swing, there is no need to worry about its obvious loosening.

and it also has IPX4 standard waterproof design, which can cope with sweat or light rain during sports. While providing excellent wearing stability, its ear hook will not bring obvious pressure to the ears, and there is no sense of existence in the second half. The overall design and weight distribution reflect a high level.

Before the audition, I upgraded UTWS3 to the latest firmware. The upgrade process can be completed directly on the mobile phone with the help of FiiO Control or Feiao Music App. It should be noted that the two earrings need to be upgraded separately. In addition to firmware upgrade, with the App on the mobile phone, users can also perform EQ settings, channel balance and other operations. In addition, the volume of UTWS3 can be controlled separately from Bluetooth devices. It supports 26 levels of independent volume adjustment, allowing users to more accurately adjust the appropriate volume.

audition, I paid special attention to it in a quiet environment. UTWS3 did a better job of controlling the bottom noise, with almost no obvious feeling. Bluetooth is connected under aptX, UTWS3 can better promote FD5, solid and powerful low frequency, full and real human voice, clear and clean high frequency... The hard quality of the three frequencies is well presented, and the density and dynamic performance of sound are also at a certain level. Although compared with wired use, its low frequency sense is reduced, and the sound field space is relatively convergent. But the ability to listen unfettered in wireless mode is enough to offset some of the compromises of sound quality.

Feiao UTWS3 makes it possible for players who hold replaceable HiFi headphones and are not satisfied with the overall sound quality of the existing real wireless headphones to wirelessly expand their "baby" applications. The solid component configuration of UTWS3 makes it possible to give full play to the sound quality level of high-quality wired headphones, which is valued by users who purchase such products. At the same time, UTWS3 also has a good performance in terms of battery life and wearing experience that users who want to experience real wireless headphones value. The price of less than 500 yuan can completely activate the "wireless" potential of your wired headset. Do you want to try it?
