You can see the earplugs and the detailed parameters and specifications of the earplugs on the back of the package. See the product parameters, the impedance of the moving coil unit used in the earplug is 32 ohms, which makes it easy for a typical mobile phone to control it, plus I use the amp to match it, which is perfect for its use. In the lower right corner, you can see CE, FC and ROHS (representing its adoption of the EU mandatory certification standard, the “Restriction on the use of certain harmful components in electrical and electronic equipment”, so the safety is very secure. ) and so on.

In accordance with the ergonomic design concept, combined with the inspiration of the power locomotive design, the earplug cavity shell is made of aerospace aluminum material, the surface is subjected to fine sanding treatment and secondary anodizing processing, and the edge is treated by multi-angle precision cutting process. To ensure that the product has a very high appearance. As a headphone designed with a graphene unit diaphragm, this is its biggest highlight. The unique patented technology constitutes a graphene speaker, which makes the bass thick and not turbid, and the sound is clear and thorough, making the drum sound dive. Deeper, the layering is stronger, and the treble is more clear and bright. The earphone is designed as a slanted in-ear design, which makes the in-ear wearing more firm and comfortable. It is not just like the earphones, it is simply hanging on the edge of the ear, and it will not fall out because of turning or jogging or fitness.

The next job is to take the opportunity. A good earplug is a must-have after starting the machine. For those who love music, they must be very familiar with the downtime, and Qukuli is ready to take the opportunity. The lossless music has come in handy. In general, the downtime is like a newly bought car. It needs to have a running-in period. Some people talk about earplugs and feel the sound field is boring, and they don’t realize what the bass is. There is also a thorn sound on the frequency, which is the problem that does not occur when the earplugs are down. After the machine is about 100~200 minutes, the sound of the earphones is really different. For the listening of pop music, it is very enjoyable. During the listening process, it feels that its low frequency potential is large enough and very texture. The details of the vocalization on the medium and high frequency are also clear.






The performance in terms of vocals is relatively stable and thick, and there is no murmur. When listening to soft songs, you can find many details in many songs, and the audio details are good. When listening to Tsai Chin's lossless music, the low-frequency dive is deep, the bass is low, and the atmosphere of the song is outstanding. It is easy to bring people into that mood. Compared with the high-frequency aspect, the performance of the HI-820 is relatively stretched, and the song is sharp and sharp, and it is very quiet and powerful. The rivers and lakes with soft and soft taste are very natural. In the low, medium and high frequency performances, the HI-820 has a solid and powerful performance, which brings a multi-level performance to the listening of music, so that people can enjoy the true meaning of music.
