SW206 80W Active Dual-Mode Bookshelf Speakers, 4inch Studio Monitor and HiFi Mode, Optical Coaxial TRS Aux Bluetooth 5.0 USB with 24bit DAC, for Home Music System Turntable TV PC Desktop, White

Great product!
The sound is spectacular, that is important to me, a musician. Super high fidelity even for a small speaker. Price is excellent, fast service. Best speaker set I have for listening to music. Easy to set up and use.

Great Product
Works great with no complaints. Only annoyance is audio delay through Bluetooth. Aux input works fantastic though. Sound quality is great for price.

volume knob doesn’t work, inadequate documentation, USB mode is extremely flaky
These are total bargain-bin speakers, poorly engineered, with design defects and no useful documentation.The biggest engineering bug is that the volume knob doesn’t work when you use it with USB. This problem is no documented anywhere on the Amazon page. It does seem to be discussed in the printed booklet that comes with the speakers, but the English is so bad that it’s hard to tell what they intended to say: “Note: When using Bluetooth mode and USB cable connection mode, the speaker volume may share the same volume with the device, so the main volume knob is not set with the highest and lowest volume scales.” If you can understand that sentence, then good for you. I’m guessing it came straight out of Google Translate.The speakers can be used in three modes, but the printed booklet that comes with the speakers doesn’t mention how to set the the mode. For this information, you need to carefully look through the Amazon page, where they have this note: “Long press 2 seconds to change the mode, green is audio mode, red is USB connection mode, blue is Bluetooth mode. ” I assume “audio mode” is intended to mean using it with a phono jack. “Long press” refers to pressing and holding the volume knob for a couple of second. This is really bad engineering. For usability, all they needed to do was make the thing detect when it’s connected to USB. (Hey, it’s not that hard for a USB device to detect that!) As it is, you get the thing out of the box and plug it in through the USB cable, and you have absolutely no idea why it isn’t working.The micro-USB cable they supply does not mate nicely with the port on the back of the speaker. It’s hard to tell whether you’re pushing it in hard enough or not. Low-quality parts, cheap engineering.One speaker has all the connectors sticking out of the back. The power cable sticks out about 6 cm. This is awkward when you’re trying to fit the speaker into a confined space, e.g., it wouldn’t fit on my windowsill. So if you’re buying these because they look compact, keep this in mind.The only good things I will say about these speakers are that they do have pretty decent bass response, and they were certainly cheap.[EDIT] I spent an afternoon doing some coding while playing sound through the speakers, and I experienced even more problems.The biggest hassle is that the USB input worked fine for a few hours and then abruptly stopped working in the middle of playing something. I tried power cycling the speakers, but that didn’t help. I had to shut down my computer and reboot to get the speakers working again, but then the USB input stopped working again after a couple of minutes. As a last resort, I plugged the speakers in via the analog phono-plug cable (which luckily I’d saved). This fixed it, but it eliminated one of my main reasons for having bought this particular model of speakers, which was that I wanted something with USB input.A second thing I noticed is that the broken behavior of the volume knob is not even consistent. What I originally observed was that the knob seemed to have no effect when I was in USB mode, and I assumed that this was what was being documented in the tortured English of the documentation, as quoted above. But I later noticed that turning the knob while in USB could actually have three different effects: (1) sometimes it has no effect; (2) sometimes it works; (3) sometimes it deactivates the speakers and the only way to recover is by power cycling.So basically it looks like whoever made the USB interface was just totally incompetent and/or didn’t do any testing. The USB interface is just completely unusable my experience.A final issue is that when I was in USB mode, I found that for some material (e.g., the PBS News Hour’s streaming programs on their web site), the sound output was extremely low — e.g., too low to be easily audible when there was background noise such as a fan. This seemingly can’t be fixed in software, because even when I max out my operating system’s volume control, I just can’t get a level through the USB interface that is loud enough. Of course, if the volume knob worked while in USB mode, then you would have a way to convince the speakers to give some more gain — but as described above, that’s a disaster.

Me gustaron, la verdad para ser de escritorio se escuchan bien, además que son blancas y son un poco difícil encontrar un color blanco y que suenen bien! Lo recomiendo 🙂

Les enceintes sont très jolies et de qualité, installation très simple que ce soit en Bluetooth ou filaire, le son est très bon, attention toute fois à ne pas les mettres dans un recoin car les basses vont sur dominer le reste et ce ne sera pas agréable, au possible les mettres à hauteur de tête pour une écoute optimale et un son bien homogène !!! Dommage que la marque ne propose pas de support prévue à cet effet.Rapport qualité/prix super
