The last experience of Panasonic's audio products may be traced back to the Walkman when we were students. After so many years, we are all old, but our pursuit of a good voice has not changed. Recently, I had a close contact with Panasonic again. This time, it was not a walkman, but a Panasonic RP-HD5 headworn Hi Res Audio high-resolution headset with a 40mm driver, which was positioned as an entry-level product. After two weeks of experience, I also have a deep feeling about this product. There are many highlights. Whether it is the ultimate wearing comfort or the sound characteristics brought by the four-way adjustment design, it is worth sharing with everyone. The package of the headset is a black box, which is relatively low-key. From the package, we can see that the complete model of this product is RP-HD5. There is a scratch label on the package to verify the authenticity. The headset has a 6-month free warranty. The package is almost all in English. There are many pictures and descriptions of the four-way adjustment of the headset products. In addition, there are corresponding pictures and texts about the wearing and unit diaphragm.

At first glance, there is nothing special about the appearance of the earphones. The earphones are calm and grand in style, and the overall structure looks plump and mellow. The earphone is a headworn ear wrap design, and its appearance is made of black plastic. The leather texture on the head beam and earmuffs is prominent. In addition, the thick sponge is also very conspicuous, which is different from the thin and thin feel of many entry-level earphones. HD5 obviously uses more abundant materials and pays more attention to wearing comfort.

The earphone is designed as a one-sided outlet, which is very compact, and the earphone cable is also very soft, with excellent flexibility, which is very conducive to the convenient use of cable management and normal travel.

The headgear and earmuffs are not only made of leather, but also the sponge is very thick. It feels very elastic and soft when pinched, which makes the Panasonic HD5 much more comfortable than many other earphones of the same grade. The thick, soft and elastic sponge is one of the reasons.

Earmuffs are runway type, large in size, full ear design, right drop, you are right! In addition, the dust-proof mesh cover in the earmuff is not an exaggeration. Through the mesh cover, you can directly see the 40mm HD drive unit inside, including the diaphragm voice coil. It is completely transparent and has a frame on the diaphragm, which can reduce unnecessary resonance and vibration. It can be seen from the label on the unit that the frequency response range of the 40mm unit of Panasonic HD5 is 4Hz-40kHz. The high-quality drive fine tuning kinetic energy is particularly excellent for low frequency performance.

The steel bands on both sides of the earphone can adjust the size of the earphone. The sliding steel band has a clear sense of scale, and the sliding feel is also very good, with appropriate tightness.

The biggest feature of Panasonic HD5 earphones in terms of appearance, structure and wearing is probably the design of four-way adjustment. I believe that friends who often play with earphones have this feeling. The more comfortable they are with high-end earphones, the more comfortable they are with entry-level earphones, Otherwise, the earmuffs worn cannot fit perfectly on both sides of the cheeks due to structural constraints, affecting the airtightness and thus affecting the sound performance of the headphones. Panasonic's four-way adjustment design is indeed very different, completely overturning the problem of wearing comfort of entry-level headphones. First, as shown in the figure below, there is a certain small angle between the ear muff and the frame in the vertical direction that can be adjusted,

In addition to the small vertical angle that can be adjusted, the horizontal part also has a large angle rotating shaft design, which can not only make the headset fit better in the vertical direction, but also make the horizontal part more consistent with the face shape.

In addition, there are scale marks on the fuselage on both sides, and the earmuff part and the headgear frame can slide back and forth horizontally. When wearing, the headgear and the earmuff part can be displaced. The two parts can be worn according to their most comfortable positions. The four-way adjustment design also makes the overall wearing of Panasonic HD5 earphones look less rigid than ordinary earphones, It is more flexible, different from person to person, so that the earphones can be closely matched with different cheeks and head shapes of different people. The four-way adjustment design is really a practical and smart design, allowing users to experience the ultimate wearing comfort.

The sound performance of Panasonic HD5 headset, which is an excellent product to wear, naturally makes me curious. I listen to the sound. The sound source player is two portable players, Shanling M2 and Seven Rainbow C10. The sound source is mainly the usual lossless and MP3 format. The two players can easily promote the earphones. Generally speaking, the three frequencies of the earphones are relatively balanced, the sound is relatively soft, belongs to the listening style, and the sound density is good. Perhaps the only problem is that the high-frequency performance of some songs is slightly dark, lacking a sense of penetration, and the connection between the middle and low frequencies is relatively natural and complete. The performance of female voice is better than that of male voice. The male voice is somewhat dark in high frequency, and the female voice is much better. The sound field of the earphones is relatively wide, and the sound base is relatively thick. The performance of the middle and low frequencies is still good. Here are the listening feelings of several songs:

In the Listen by Beyonc é, a famous American pop queen, HD5 performs extremely well on the Seven Rainbows C10. It is full of tension but has a soft sense of hearing, without the sense of noisy ears, which reflects Beyonc é's broad vocal range and is very infectious. The vocal knot image is clear, the soundtrack does not cover the vocal voice, the vocal density is very good, and the soundtrack maintains a good sense of hierarchy. The momentum of the queen shows completely, which makes people cannot help listening to it twice more.

He Xuntian - Dust Drum. The drum point has a clear position. Every beat has a sense of flesh and not dry, and the atmosphere is full. You can feel the air wave of the drum sound. The whole song maintains a good sense of hierarchy and dynamics, and a sense of warm drum sound.

Don Davis-Tetsujin ， The music is selected from The Matrix Revolutions, an original album of the Matrix Empire. It appears in a scene of gunfight after the Chinese led Neo and others to find the French. The scene is strange and mysterious. The guards can climb freely without gravity restrictions. The visual effect is excellent. As the soundtrack of this scene, it also needs to follow the requirements of the scene design,

Tetsujin combines the characteristics of oriental percussion music. The rhythm and percussion force are changeable, and the requirements for bass are extremely strict, and the requirements for listening equipment are very high. The climax part of the song has a fast, rapid rhythm and many musical elements. It is difficult to calm down and stabilize the sense of hierarchy when listening to the music with less excellent equipment. Playing this song at a medium volume, Panasonic HD5 keeps the stability of the sense of rhythm well, and the rapid drumbeats are always around the ears. Both the Mountain Spirit M2 player and the Seven Rainbows C10 have excellent dynamic and transient performance, without a sense of chaos. The climax part has a fast rhythm, full of tension, and soul stirring, When listening, it is completely brought into a tense world by the sense of rapid rhythm. In the wide sound field, the musical instruments at different positions have a clear sense of direction, and each kind of music element can be clearly identified. It perfectly demonstrates the characteristics and charm of this music. Every time after listening to this music, it still feels that the music is too short, The ear is still echoing that kind of soul stirring melody.

In Zhao Peng's "Going to the West Building Alone", the voice seems a little too deep, a little old-fashioned, not analytical enough, and a little stuffy.

Guzheng "Butterfly Lovers" is sweet and comfortable, and the beauty of sadness and sadness is in place. It will let people imagine the video scene of Butterfly Lovers while listening. It is urgent and slow. The soft listening sense of HD5 makes this love story a little moving.

Big Up by masked brother Wang Shang Wenjie, HD5 has a bright high frequency, soft and stretched voice with rhythmic accompaniment, and the sound density is good, making the song interpretation feel smooth and enjoyable.

In a word, the feeling of Panasonic HD5 earphones is that thin dew is exciting and four-way adjustment is comfortable!
