In the era of wireless, even earphones and speakers are gradually becoming wireless, and more and more brands continue to invest in the development of such products, which also makes wired products that have been popular for a long time. Even so, wired headphones are still loved by many listeners. After all, they still have certain advantages in terms of detailed sound performance. If you want to have the sound quality of wired headphones at the same time, but also want to enjoy the convenience brought by wireless, perhaps the AQUA+ Bluetooth wireless ear extension launched by Taiwanese brand NEXUM Magic Technology can meet such needs. As a wireless evolution version of the previous generation AQUA, the new AQUA+ also has a lightweight and portable body design, and has built-in AMP, 32bit upscaling chip and wireless charging functions, making wired headphones in the home wireless in place. It is AQUA+ Want to bring the best experience to consumers.

The AQUA+ wireless charging disk uses the most popular BC858AWT1 Qi charging. Simply put, if you have a wireless charging stand from Muji or IKEA at home, you can also charge this product. There is a micro USB port on the back of the charging disk. When charging, please make the face with the brand name face up to charge it smoothly, and a red indicator light will appear on the side of the product during charging.

The input voltage specification of this wireless charging disk is 5V / 1.5A / 7.5W configuration, and the actual charging is about 5W. I have tried the iPhone X in my hand, and the Galaxy S8 of the mobile version editor Nanako can be charged smoothly, simple It is said that as long as the device that supports Qi wireless charging can be placed on it to charge. But Xiaobian actually used the iPhone X to charge for 20 minutes, and the power was only increased from 75% to 79%. The charging speed is a bit insufficient, but it can be used as an additional charging base. It is also a good choice.

A leather case clip with a back clip is also attached, and the outer covering material of the wireless charging disk is made of microfiber leather, which is comfortable to the touch, but there are concerns that it is easy to get dirty. If so, remember to charge the product side, do not use it on the side with the metal back clip, otherwise there will be a dilemma of not being able to charge.

The officially released version of the AQUA+ wireless Bluetooth earphone has the golden color that Xiaobian got. In fact, it has a little brown feeling. In addition, it also offers an all-black color matching version. If it is an all-black version, the attached charging disk and leather case clip are also available. will be the same color. The product name and functional characteristics are printed on the front of the product, and the pattern of wireless charging is printed on the back.

The operation part of AQUA+ is set on the side of the product with metal hairline, with 3.5mm stereo jack, indicator light and built-in microphone, power button and 32bit up-conversion button, and finally the multi-function button and the multi-function volume of the volume. knob.

The following editor provides the actual operation method of the buttons and dials for your reference:

Press and hold the power button for 3 seconds: turn AQUA+ on/off

Multifunction Knob: Increase volume clockwise/decrease volume counterclockwise

Press once to play/pause or answer/end a call

Press twice - next song

Triple press - previous song

Press and hold for one second - activate Siri/Google Assistant

32bit upscaling key: Short press - enables 32bit / 384K sampling

Short press again - restore 16bit/44.1K sampling

When the oversampling function is turned on or restored, in addition to listening to the difference with your ears, you can also tell which sampling mode is currently in the indicator light on the side of the fuselage. The dark blue light means 16bit sampling is used, and the light blue light means Represents 32bit sampling mode.

The use of AQUA+ is also very convenient. Users only need to press and hold the power button for about two seconds and see the indicator light flashing dark blue and red, which means that the product has entered the Bluetooth pairing state. Just connect the AQUA+, then connect the headphones to listen to music.

The device used by the editor for the audition is SONY Walkman NWZ-A15, which supports Bluetooth and Hi-Res high-resolution music formats. The headphone part is UE 18 Pro, which uses Bluetooth 4.2 version of AQUA+. The stability of the Bluetooth connection is The performance is quite good, and there is not much signal interference. When listening to music, the editor uses HR music format with 32Bit sampling mode. Through these two high-resolution music formats, and the product supports aptX transmission, the compression of music can hardly be felt at all, but it is not difficult. It is felt that the tuning is mainly based on mid-high audio frequency and human voice, the mid-range is stable and durable, the treble is clear and without sharpness, and the details of the human voice are quite obvious, but the strength and extension of the bass part are not so obvious. If you want to listen to music with a strong sense of rhythm, it may be a little more reluctant.

As for the analysis ability of the sound, the editor believes that the UE 18 Pro can still reach the upper-middle level, and the sound details of the musical instrument are obvious. Of course, this also has a lot to do with the headphones used. If the original analysis of the headphones Power has a certain level, with 32bit sampling mode, and even with lossless music format, although wireless music transmission can still distinguish a lot of sound details. The editor also uses the general MP3 format to listen to the difference between the 16bit and 32bit sampling modes. In fact, the main difference lies in the sound details and layering. Of course, there are also certain differences in the analysis ability, but the basic tuning is not too much. A big change, which is also provided for your reference.

In the end, the editor also borrowed SONY XBA-Z5 headphones with Walkman NWZ-A15 for trial listening. Unfortunately, SONY has not yet opened the LDAC transmission specification, so AQUA+ can only handle the transmission specification of the highest aptX, but the basic tonality of Z5 headphones It still exists, the resolution and sound quality of the sound are quite good, the vocal performance is also quite durable, the bass dive depth is enough, although the strength is a little insufficient, but the bass effect can still be heard, and there will be no pressure and discomfort after listening for a long time. Feel.

After reading the detailed specifications above, I would like to share with you the experience of NEXUM AQUA+. What impressed me most is its light and portable convenience. With wireless charging and leather case clip, the overall weight is less than 100g. It can be carried out and used at any time, and the devices of various systems can be used together as long as they support the Bluetooth transmission function, which can adapt to different use situations. The most important thing is that AQUA+ can instantly upgrade the wired music playback system that has not been used for a long time to a wireless device system. It is really a very useful functional design. In addition, I have tried the overall battery life. Play HR music format, in 16bit sampling mode, about 7 hours and 57 minutes, using 32bit sampling mode, about 5 hours and 16 minutes, also provided for your reference.
