When it comes to sound quality, the AIYIMA S400 delivers a surprisingly pleasant experience for its size. The highs are crisp without becoming harsh, and the mids have a nice warmth that brings vocals and instruments to life. However, if you’re expecting deep bass that rattles your walls, you might want to look at a larger setup.
In a small room or a nearfield setup, these speakers perform admirably, filling the space with a balanced sound. They’re great for casual listening, but if you’re an audiophile looking for that last ounce of detail or bass extension, you may find yourself wanting more.
The build quality of the S400 feels solid, and the design is sleek enough to fit into most environments without clashing with your decor. The wood finish gives it a bit of character, and the controls are intuitive. It’s not overly flashy, which I appreciate; sometimes less is more.
One thing I really liked is the remote control, which feels more robust than you might expect. It’s handy for switching inputs or adjusting volume without having to reach around to the back of the speakers, making day-to-day use a lot more convenient.
Setting up the S400 is a breeze, especially for beginners. You just need to connect your turntable or other audio sources via RCA, optical, or coaxial, and you’re good to go. If your turntable has a built-in preamp, you can plug it directly in and start enjoying your records right away.
However, this ease comes with a caveat: if your turntable outputs only a phono signal, you’ll need to add an external phono preamp to the mix. This is a common pitfall for first-time buyers, so it’s something to keep in mind before you dive in.
04Connectivity & Features
The S400 shines in terms of connectivity options. With RCA, optical, coaxial, and Bluetooth inputs, it’s versatile enough for a mixed-use setup where you might want to connect a turntable, a TV, and a laptop. This makes it a solid choice for small apartments or desks where space is at a premium.
While the Bluetooth feature is convenient, I wouldn’t recommend relying on it for your turntable. The wired connection via RCA still delivers a cleaner sound, which is what you want for vinyl. So, while Bluetooth is a nice bonus, it shouldn’t be the main reason you choose these speakers.
One of the trade-offs with powered speakers like the S400 is the limited upgrade path. With passive speakers and a separate amplifier, you can swap components over time, but with the S400, you’re more locked into the system as a whole. This isn’t necessarily a dealbreaker, especially if you’re just getting into vinyl, but it’s something to consider if you plan to grow your setup.
In a small bedroom or nearfield setup, the S400 is usually more than sufficient, but if you’re looking for a more scalable solution, you might want to explore passive options. Just remember, if you’re still figuring out your audio chain, start with understanding what a phono preamp is before you make your final decision.
