The exquisite and compact appearance basically continues the classic appearance style of the previous generation A45. The arc design on the side of the fuselage conforms to the curvature of the hand, making the hand feel extremely comfortable. The main body of the fuselage is made of high-density, low-impedance and durable aluminum alloy. The upper and lower back covers are covered with frosted plastic, which will not easily leave fingerprints on the body.

You can complete song selection, sound setting and other operations by sliding. In terms of battery life, Sony NW-A55 can continuously play about 25 hours of DSD high-resolution audio, or about 45 hours of MP3 audio playback. The high-intensity battery life brings users the ultimate and casual music enjoyment.

In terms of sound quality

As a music player, it still has to speak with hard power. The quality of sound determines the popularity of the product. Sony NW-A55 has done everything to improve the sound quality. Physically, it uses the same aluminum body as NW-ZX300, which makes the bass stronger and clearer. The board and the body are directly connected using the onboard board and contact spring to reduce impedance, improve the bass effect of the player, and make the mid-range clearer. The connection between the circuit board and the battery line is spot-welded with a new type of high-quality lead-free solder containing a trace of Au, which greatly improves the clarity of the sound and vocals.

In terms of software, with the optimized "DSEE HX", users do not need to manually select the music type, AI machine learning, real-time analysis, and automatic selection. At the same time, Sony NW-A55 has also expanded the high-frequency range, optimized 44.1kHz content to 176.4kHz, and optimized 48kHz content to 192kHz, further improving the performance of high frequencies. The scale is optimized from 16bit to 32bit, bringing high-quality music listening. At the same time, the equalizer preset of A50 is changed to the preset of Headphones Connect, which is more suitable for use when wearing headphones.

From the results of use, the NW-A55HN set player works quite well. First of all, the player can be used as a Bluetooth receiver, and the sound effect can be adjusted during use. With the official headphones, the overall sound quality of the song can be improved to a higher level. Secondly, the EQ effect is more obvious than the previous generation ZX300a, and the frequency bands are integrated into 6, which is more convenient to operate. For 1899 yuan, you can enjoy the high-resolution music quality and fly in the world of music.
