Sony WH-H800 headphones' best companion NW-A45 player will be your new choice for pursuing good sound quality

Although more and more smartphones are now adding Hi-Fi features to their selling points, a multi-functional mobile phone is not a dedicated music playback device after all. Especially for professional music lovers, the improvement of music playback quality by mobile phone Hi-Fi is relatively limited.

In the more professional music player field, Sony Walkman is undoubtedly the most familiar name to consumers. As the latest product in the Walkman series, Sony NW-A45 also carries the mission of using younger product thinking to meet the high-quality music needs of more users.

Outstanding design highlights quality and massive storage of thousands of songs

The product model we experienced this time is the Sony NW-A45HN, which includes the NW-A45 music player itself and the Sony IER-NW500N in-ear wired headphones that come as standard.

The Sony NW-A45HN package contains a pair of Sony IER-NW500N headphones with the same color as the NW-A45 player. And like Sony's new headphone products, the unique color scheme is also a highlight of the product appearance. The moonlight blue version of the product in our hands looks completely different from the previous dull player image, and it further highlights the youthful product thinking.

The appearance design of the Sony NW-A45 player clearly reflects the consistent industrial design advantages of the Sony brand again. The compact body weighs less than 100g and the front is equipped with a 3.1-inch TFT color display that supports touch operation.

In terms of details, the brand logo above the Sony NW-A45 screen and the walkman logo at the bottom are both raised and polished, giving the product a strong sense of quality.

On the right side of the body, Sony NW-A45 is similar to other Sony player products, providing many physical buttons including power, volume adjustment, playback control and screen lock. In addition to touch operation of the product, users can also easily put the player in their pockets and operate it blindly while listening to music.

On the other side of the body, the Sony NW-A45, which has an internal storage capacity of 16GB, also provides a MicroSD card slot that supports up to 128GB of expansion, which means that this small player can hold up to thousands of high-quality music files.

S-Master HX full digital amplifier supports 30 hours of ultra-long battery life

Regarding the sound quality that users are most concerned about, the addition of the S-Master HX full digital amplifier has become the killer feature of Sony NW-A45 to bring true sound quality.

By selecting high-quality lead-free solder and improving the soldering technology of the S-Master HX integrated circuit, Sony NW-A45 can greatly enhance the clarity of musical instruments and vocals when playing music. At the same time, it supports DSD format playback in the form of PCM conversion, so that when connected to a DSD-supported headphone amplifier, it can output native DSD format, bringing higher-specification audio output.

In addition, Sony NW-A45 further optimizes the internal circuit board layout, improves the current flow of the power supply, reduces the signal circuit impedance and enhances the power supply. The unique DSEE HX technology can make the sound quality of compressed sound sources surpass that of CDs. While bringing clear and powerful sound, it can also enhance the existing sound sources to the same level of sound quality as high-resolution audio.

The IER-NW500N in-ear wired headphones that come standard with the Sony NW-A45HN use a 9mm high-sensitivity driver unit that supports high-resolution audio, an external magnetic ring design to improve driving power, and an optimized diaphragm to present a broadband frequency response of approximately 5Hz-40KHz, making it a good partner for the NW-A45 player to deliver high sound quality.

What is more worth mentioning is that in the Sony NW-A45HN, the cooperation between the NW-A45 player and the IER-NW500N in-ear wired headphones brings users automatic AI noise reduction technology, which also demonstrates an extremely intelligent noise reduction experience. The playback device can continuously analyze the types of noise in the surrounding environment, and automatically select the ideal setting from the three noise reduction modes of airport/train car/office to ensure the clarity of music playback in different environments.

Of course, Sony's NW-A45 player has not ignored the growing love of wireless headphones among users. Under the LDAC transmission protocol, the NW-A45 player can transmit about three times the amount of data between Bluetooth headphones that also support the LDAC protocol, compared to ordinary Bluetooth, achieving a maximum transmission speed of 990kbps for enjoying Hi-Res Audio music wirelessly. In terms of connection, the NFC contacts on the back of the player greatly simplify the pairing process of wireless playback devices.

This means that Sony's WH-H800 wireless headphones, which are currently very popular among young people in the market, will also be an ideal choice for you to enjoy wireless high-quality music using the Sony NW-A45 player. Both devices support NFC, which can achieve more efficient Bluetooth pairing.

Finally, when it comes to the frustrating battery life of smartphones, the Sony NW-A45 player, which looks like a mobile phone, has demonstrated strong strength. Sony officially claims that when playing high-resolution audio with a specification of 192 kHz/24 bits, it can continuously play for about 30 hours, and when playing MP3 audio with a specification of 128 kbps, the continuous playback time is even more exaggerated, reaching about 45 hours, so that the battery life of portable products is no longer a shortcoming for users pursuing good music.

In general, the Sony NW-A45HN, which is currently priced at 1,899 yuan, includes a high-quality music player and in-ear headphones with excellent sound quality. Its overall performance meets the demands of the vast majority of users who are used to listening to music on smartphones for an upgrade in music quality.

Although it is not as good as other Sony players that cost tens of thousands of yuan and include a wide variety of black technology configurations, the Sony NW-A45HN is still a qualified walkman product. In the current era of mixed mobile phone Hi-Fi, with a relatively reasonable market positioning, it provides music lovers with a new choice for pursuing good sound quality.
