Listen to the wired output and 360 Reality Audio of the "audio smartphone" "Xperia 1 III"

Equipped with a nice 3.5mm earphone output

Let's check the sound aspect, which is the main part of this time. First of all, it has a 3.5mm earphone output. As you know, earphone output is a precious existence that is disappearing from smartphones these days. Considering the popularity of wireless earphones, there are many people who feel lonely because they can't use their favorite wired earphones.

Of course, if you connect a conversion cable or a portable amplifier, you can use wired earphones even if your smartphone doesn't have an earphone output. Thank you.

Also, it's not just that "I just added an earphone output", but it's the audio manufacturer Sony's point of being particular about the sound quality. A smartphone is a machine packed with various parts that emit noise in a very limited space, but it is said that thorough measures are taken to prevent such noise from affecting the sound.

In the new model Xperia 1 III, the maximum sound pressure is improved by about 40% compared to the previous model "Xperia 1 II". You can enjoy music at a higher volume, and it is easier to use low-efficiency earphones/headphones. By the way, the previous model Xperia 1 II won the Audio Visual Award "VGP2021", and the new model Xperia 1 III also won the "VGP2021 SUMMER", both of which won the "Smartphone AV Quality Award". The Xperia 1 III is the evolution of the highly rated AV function.

Let's actually listen to the sound with wired earphones. Play the 96kHz/24bit file of "Best of My Love" from "Emi Fujita/camomile Best Audio" with the standard "Music" app. By the way, this app can play high resolution without adding plug-ins.

At the beginning, the music starts with the acoustic guitar solo on the left side, but at this point you can already see the goodness of the sound. The sound of the guitar spreads out like ripples in a quiet sound field, but the "soundless space" in the background is "steadily quiet." With a noisy smartphone, the "soundless space" becomes noisy, and the sounds of musical instruments become unclear. With the Xperia 1 III, the silent parts are completely silent, and the sound of the guitar rises in a space without sound. The contours of the instruments floating in the sound field can be clearly heard, and the sound is three-dimensional and vivid.

The female vocal that comes after the guitar is also natural. People's voices are familiar to us in our daily lives, so if they sound unnatural, it's easy to feel uncomfortable.

What I'm interested in is the bass of the acoustic bass that comes in after 1 minute. This sinks firmly with "zoon", and "low sound" comes out properly. It's not "what a bass" with an expanded mid-low range.

There is a solid core even in the deep bass. The base does not bulge unnecessarily and has a moderately tight fit. Because the resolution is high, the low-pitched sound of "zoon" is not over-emphasized, and you can hear the fine sound of the strings vibrating in the low-pitched sound.

Not only the SN ratio is good, but the driving power of the amplifier that drives the earphones must be high to produce such low frequencies. This is a weak point for completely wireless earphones that have a built-in amplifier in a small housing, and the goodness of wired earphones can be demonstrated.
