Really decent for the price. My new tv is so streamlined that it really can't have cables, so I've been using them hassle free via Bluetooth.

Die Aktiv Boxen werden hier teils hoch gelobt, zu Recht wie ich finde... habe die Boxen zum Abspielen der Klassik Radio App gekauft, da mich seit ewig schon der fehlende Raumklang bei meiner JBL Charge 5 Box störte. Prima auf der Terrasse oder die auf Reise mit zu nehmen, aber im Wohnzimmer erwartete ich doch mehr Raumklang. Und das kann die S400 bieten. Sauberes Klangbild in den mittleren und hohen Tonlage, verzerrfrei! Bass spielt bei der Klassik nur eine untergeordnete Rolle. Und Dvořák sowie Puccini komponierten weder Beat noch Techno! Jedoch: Die Musik wird über eine App auf einem 6 Jahren Samsung A50 gestreamt. Bluetooth Basis, mehr gibt's nicht her. AptX, AAC, SBC und Co. Fehlanzeige, gibt's nicht bei dem alten Teil, nicht mal bei den aktuellen Flagschiffen. Allerdings habe ich einen Equalizer herunter geladen und mir dort den Klang eingestellt, auch den Bass. Tschaikowskys und Chopins Klavierkonzerte klingen kräftig, Haydns Paukenschlag ist auch einer. Für mich perfekt. Was den in anderen Rezensionen kritisierten fehlenden Bums an Bass betrifft: Die Boxen haben ein Volumen von nicht ganz 3.000 cm³, wo bitte soll da die Kraft her kommen? Und bitte den Preis nicht vergessen.... Wer Techno-Partys feiern will mit bebenden Fensterscheiben braucht was anderes. Aber für Wiedergabe über den Laptop bei der Arbeit, Musik beim Kochen, Hausputz oder im Hintergrund bei Gesprächen ist die S400 bestens geeignet. Übrigens lassen sich bei den Equalizern zumeist die Musikarten wie Folk, Pop Jazz oder Schlager vor einstellen. Ich bin sicher, dass sofern keine extreme Ansprüche an Lautstärke und Bass gestellt werden, können auch Fans anderer Musikrichtungen klar kommen. Und nicht vergessen: Bei nicht mal 100 € für die S400 wachsen die Bäume nicht in den Himmel, wer mehr will, muss mehr ausgeben. Meine Empfehlung: einfach ausprobieren, zurück schicken geht immer. Das Preisleistungsverhältniss finde ich in Ordnung. Ausprobieren auch deshalb, weil die Inbetriebnahme super einfach ist. Boxen mit RCA-Kabeln verbinden, Netzteil rein und einschalten. Mit der Fernbedienung BT (Bluetooth) drücken, Musikquelle koppeln. Fertig. Anleitung ist ausschließlich in Englisch und eigentlich ein Witz. Bilder, die graphisch die Elemente erklären und wo welche Stecker angeschlossen werden. Kaum Text, aber war für mich zumindest auch nicht nötig... Wiedergabe des TVs ist auch möglich, für mich jedoch uninteressant daher keine Wertung. Die Anzeige an der aktiven Box ist sehr klein, nur für die Nähe geeignet. Beim Einschalten ertönt ein leichter Gong und die blaue LED leuchtet. Mich stört das so gesehen nicht. Daher: Kaufempfehlung, selber ausprobieren!

PROS: Decent build quality, Includes all the accessories, 3 Inputs, Good sound quality, Minimal design. CONS: Build quality for the price could be better. No Left/Right indicator/marking INTRODUCTION: In this review I am going to test and review their first speaker product (S400). I am only be focusing on the sound and build quality. (Check Nathaniel Huggins for detailed review of the build and inside). Before I begin talking about the sound quality and frequency, I would like you to know everyone has different hearing and taste in sound, so don't take this review too serious. WHAT'S IN THE BOX: You get a 3.5 mm to RCA cable, user manual, optical cable, power supply, and a RCA cable for the other speaker is pretty long. FIRST IMPRESSION: After unboxing the speakers I got immediately hit with confusion. Which one is left or right? The passive speaker is the LEFT speaker and the one with input indicator is the RIGHT speaker. Other than the build quality is ok, it doesn't feel cheap but weighs a bit than I expected. There are really no other indicators except for the lights and the user manual doesn't give a lot of information about the speaker and remote. The remote, yes the remote is simple to use except there's no indicator level for TREB-/TREB+ and BASS-/BASS+. Here's what I learned, treble and bass adjustment only has 4 steps. So thats -4 or 0 or +4. -4 is less, 0 is normal, 4 is emphasized (treble or bass) Other than that good selection of inputs. SOUND QUALITY: I am not expecting a lot since this is AIYIMA's first attempt at building bookshelf speakers. Just note it is impossible or demonstrate how these sound over the internet so take this review with a grain of salt. Most of the testing and listening was done on Bluetooth and RCA input. About the sound. The S400 delivers very good sound quality. I would describe the sound as Neutral Bright. I have played TOTO, Journey, Billy Idol, Fleetwood Mac, and many artists and it sounds good. The bass is good for the size of the 3" speaker drivers. They can get very punchy but the bass rolls off at 65 hz. If you want more subbass I highly recommend getting a subwoofer. Midrange is almost perfect, nice and balance. The treble department is a picky topic. Me I find the treble to almost perfect when listening up close. The vocals are emphasized and the claps and kicks are perfect, they're not piercing my ears. But if you don't like how emphasized the treble frequencies and you like rock, hip-hop, bassy music. CONCLUSION: At the time of writing the review, the S400 were retailing for 85.99 USD. And for the final thoughts I am impressed on how these perform and sound but I am slight disappointed the aesthetic design is lacking. It would be nice if it was covered in some wood vinyl. These speakers are versatile and impressive for the size. I find these to be really good at podcast and non bassy music but I wouldn't use these are reference speaker. UPDATE REVIEW: I took another frequency response of the speaker (Free Field). Thicker Line is common room measurement.

I bought these speakers for my partner to use in their office. She doesn't like large bulky speakers or having to deal with a separate subwoofer so I was looking for a small powered bookshelf set. I'm a huge fan of Aiyima's amplifiers so when I saw that they released a small powered bookshelf set I couldn't wait to try it out. Overall both her and I are quite impressed by these little speakers. I've provided more details below.Size - These speakers are fairly small and would look great on any desk. I think they'd work also work great as a soundbar alternative for a TV.Connectivity - Bluetooth works great from my phone and laptop and I'm able to walk out of the office without any disconnects. I prefer the 3.5mm connection and am glad that the necessary cable was included. I tested the optical connection with my desktop and that worked great as well. While I don't plan on using the USB I did test it out and was able to play and skip tracks without issue.Remote - The included remote is easy to use. It allows for basic treble and bass adjustments and comes with 3 EQ presets for music, movies, and dialogue that all work great. I appreciate the buttons to select each input vs just cycling through them one by one.Sound - Saving the best for last. These speakers really impressed me for their size. They get quite loud and won't have any issue filling an office or medium sized room with sound. The amount of bass coming from the 3" driver definitely surprised me. It plays down to about 60hz before the bass output begins to drop. The mids are present and smooth while the highs are crisp, clear, and non fatiguing. I tested both music and Youtube videos and found the sound signature to be lively and quite enjoyable.Overall - These speakers offer an abundance of great sound in a tiny package. My wife is quite happy with they way they look and the lack of wires compared to her old set. If you're looking for an unobtrusive set of speakers but still want decent sound quality I'd highly recommend them.
