16. Let's talk something about the HIFI Bluetooth earhook UTWS5 2025-From James

1, Why release Bluetooth ear hooks like the UTWS series?

For audiophiles, they are willing to spend much more money than TWS earphones from big brands such as Apple, Huawei, and OPPO to buy earphones for better sound quality. Existing TWS earphones, due to factors such as cost, conflict between active noise cancellation and sound quality, power consumption, size, product positioning, etc., still do not have the best sound quality.

Products like UTWS5 are designed to achieve the best sound quality while maintaining the convenience and flexibility of TWS earphones. For the acoustic part, consumers can choose their favorite earphones. For the circuit part, UTWS5 has an independent HIFI DAC chip which not only has better audio performancethan the built-in DAC integrated in the Bluetooth receiver chip commonly used in TWS earphones.

2, Why does UTWS5 2025 version need to switch to wireless charging?

It should be noted that the wireless charging of UTWS5 2025 version refers to the charging of the ear hook when it is put back into the box, instead of using a metal touchpoint connection like ordinary TWS earphones, but using the familiar wireless charging to charge the ear hook.

With this design, there is no exposed metal touchpoint on the ear hook. The old UTWS5 still uses the traditional metal touchpoint connection method. In addition, the touchpoint design is close to the head on the inside of the ear hook, so it is particularly easy to come into contact with sweat.

Therefore, the old version is prone to the metal touchpoint being unable to conduct electricity normally due to sweat corrosion, resulting in the inability to charge or disconnect from the phone after putting it back in the box?

PS, we have tried various metal materials and coatings currently available to solve the problem, and also made a small revision to separate the three touchpoints to prevent sweat from causing weak current conduction between the touchpoints, which cannot be controlled.

3,Three, my UTWS5 has no problem, why FiiO change it?

All products of FIIO have undergone systematic and strict testing and verification during the development and production process to ensure that the products can work normally and reliably. We have also conducted various tests including salt spray experiments on the touchpoint of UTWS5, which can meet the quality standards.

if you follow the product instructions and do not use it during exercise or sweating, and can clean the touchpoint promptly after use, UTWS5 can be used reliably for a long time.

Therefore, UTWS5 does not break down quickly after buying it, after all, we have also released UTWS3 with the same structural design and sold it for a long time.

However, compared to other products of Fiio, the RMA rate of UTWS3/5 is significantly higher. Moreover, we cannot attribute this problem to improper use by users.

Therefore, even if the change allows everyone to use it without being so careful, it is also to reduce the time and cost that the we spends on after-sales services.

4. Why did it take so long for UTWS5 2025 to switch to wireless charging?

In TWS products, it is extremely rare for UTWS5 2025 to use wireless charging. Currently, there is no ready-made reference or mature solution. The main difficulty lies in the fact that wireless charging relies on coils to emit and receive high-energy electromagnetic waves.

Therefore, the coil needs to have a large enough area to have sufficient charging efficiency.

In addition to charging, the ear hook and earphone case also need to exchange data to complete functions such as ear hook insertion detection and automatic connection when opening the box, and to maintain synchronization between the left and right ear hooks.

although it is only a simple replacement of touchpoint with a coil, the technical difficulty is still very high. Especially without reference and reference, Feiao needs to rely entirely on self-developed solutions to solve the problem.

Therefore, the required time far exceeded our expectations. Fortunately, it was finally resolved.

5, Why does changing to wireless charging increase the price by 70 USD?

Because the UTWS5 2025 version actually has two sets of wireless charging built-in, charging the left and right units . In addition, the wireless charging chip and special coil we use are not the commonly used wireless charging solutions on mobile phones. Therefore, our procurement cost is very high.

In fact, although the price of UTWS5 2025 version has significantly increased, the profit margin has also decreased. However, the UTWS series itself hopes to provide a good fever tool for enthusiasts. The market demand is not high, and we do not expect to make much money from it. As long as it is not a loss.

I hope everyone can understand.

6, Why hasn't the UTWS5 audio circuit been improved?

UTWS5 2025 version was planned to be launched as soon as possible, so there was no consideration of upgrading to other places (of course, the actual progress has been delayed for half a year). Another reason is that UTWS5 itself has limited space and a small battery. There is no choice except for the current AK4332.

At that time, QCC5181 was still under development and the functional improvement was not particularly significant. Therefore, we wanted to focus on solving the problem of metal touchpoint corrosion and oxidation as soon as possible, and timely restore supply to meet user needs.

As for the rest, we need to look at everyone's feedback and sales. If we are optimistic enough, we will definitely consider investing more energy to make a better TWS HIFI ear hook to meet everyone's needs.
