Key Points for Improving Sound Quality When Enjoying Audio from Smartphones: "What Are the Key Points for Cable Selection?"

"I'm connecting my smartphone to listen to music, but the sound quality isn't quite there..."

Have you ever felt this way?

The cause might actually be the cable.

Previous smartphones always came equipped with earphone connection terminals - stereo mini terminals - which allowed for easy direct connection between amplifier-equipped speakers or amplifiers and smartphones using the included audio cables or stereo mini cables. However, starting a few years ago, new smartphone models stopped including these stereo mini terminals, and to connect directly, you now need to use audio cables or conversion cables that support Lightning terminals or USB-C terminals.

Depending on the type of cable you choose at this point, audio information can be compromised, preventing wave-motion speakers from performing to their full potential, which can result in the feeling described at the beginning.
For example, simple cables available at 100-yen shops or conversion cables included with smartphones may be the cause.

This time, we'll introduce the key points for selecting high-quality cables recommended by M's system, along with specific cables you can trust.

There's one key point when selecting cables:

◎ The cable must support HIFI sound quality or Hi-Res sound quality

Cables that support HIFI sound quality or Hi-Res sound quality will convert your smartphone's digital audio signals into high-quality analog audio signals.

Here are the cables that M's system uses during listening sessions and demonstrations.

M's system uses the following two types of cables.
We can confidently recommend these cables.

・Lightning terminal compatible cable (compatible with iPhone 14 and earlier)
　JSAUX aux Cable Lightning to 3.5mm [HIFI Sound Quality]

・USB-C terminal compatible cable (compatible with Android devices, iPhone 15 and later)
　UGREEN AUX Cable USB C 3.5mm Conversion Cable [Hi-Res Sound Quality]

If you suspect that the cable might have been the cause, please give these a try.
