About Bookshelf speakers
Bookshelf speakers are used to reproduce audio.They’re designed to maximize sound in small to medium-sized spaces.
There are many sizes and uses for them. “Hertz” and “Watts” are important quality indicators, but they are not the only ones.
SW208 has bluetooth technology.
SW208 (Main Features)
This is what the manufacturer says:

It has excellent sound performance, warm and thick medium frequency, deep and powerful low frequency, clear and bright high frequency sound characteristics. And the speaker unit has a super durability and stability, can work steadily in any environment.

- To achieve true HiFi sound quality, set the total volume, treble and bass adjustment knobs on the side of main speaker. Please adjust the most suitable sound according to your preferences, or adjust the best sound effect according to different sound types.

Price Range
Low price, in relation to other 166 bookshelf speakers. (My research)Cons (for information)
My first issue is they don't seem to actually support aptX, at least in Android 11 / Google Pixel 4 XL. SBC only. My second issue is the DAC appears to be a 16-bit/48 kHz. Finally my set has a bad rattle at moderate volume, >70dB. The rattle is somewhere on the control board (RCA, 3.5mm, micro USB board). I was able to greatly reduce it with a couple of fixes but not eliminate it. The first was copiously hot gluing the control board and cable connectors, at least one was loose enough to rattle when touched (Black and white pair). The second was tightening the screws holding the control board onto the back plate, my top screw was very loose. Thirdly the micro USB port has 2 problems; 1) it seems to rattle against the back plate, if I hold it with a small probe like a mechanical pencil tip it stops. 2) somehow it's allowing the remaining rattle to exit the speaker unimpeded. Placing a piece of electrical tape over the connector greatly reduced the overall volume of the rattle. After all these fixes I've reduced the volume and changed the overall tone of the rattle. I can get to almost 80dB with neutral bass before it bothers me. But I can't unhear it, so I'm painfully aware of it. There's still rattle from the back plate, and I believe I'm hearing some from the faux tweeter. Neither of these I can find a fix for.
