BESTISAN Bookshelf Speakers - Powered Bluetooth Speakers with 4 Inch Woofer, RCA Input, Sub Output, Wood Grain Design - Perfect for Home Theater, Gaming, and Music Listening

I'm very happy with these. I wanted something reasonably priced and consistent for audio mixing, as well as just listening to music when I'm working. The typical 2.1 computer speaker outfits just weren't cutting it for me, so I started looking for something a little more classically trained.They feel like they're made from quality materials. The MDF box is solid and secure, so there's no rattling or unwanted resonance. The 4" woofer cone and dust cap are paper with a rubber surround which sounds very sensitive and well balanced at any volume level, and they do get quite loud. The drivers are well matched, as the frequency response seems consistent at all volume levels as well. There is no sub-bass response to speak of (below 60hz) which is expected, but as long as you're not looking for thumping bass, these do a great job of reproducing everything else.The controls are nice, with the only confusing aspect being the color of the LED that indicates which input is selected. The manual is the only guide to what each of the colors means. Blue = bluetooth, so at least they made that intuitive. The remote control takes all the guesswork out of selecting the correct input though. The remote works well too, it's not at all finicky as long as you point it in the direction of the right speaker (where the IR sensor is located). I'm kind of looking forward to trying the SPDIF input as that's a really rare feature of active monitors in this price range.The remote allows you to control track selection and play/pause when connected to a device via BT. The BT receiver does not stay connected to your device when it is not in BT mode. As soon as you switch the receiver to a different input, it drops the BT connection, but my iMac also reconnected to them within 2 seconds of switching them back to BT mode, so I'm very happy with the way that works. The audio quality with my iMac is slightly better when plugged in through the aux input vs. BT mode though, which is a bit of a testament to their quality I think (given that BT streams are compressed, its good that you can tell the quality difference between compressed and uncompressed sources).The DSP effects are too weird for my ears, but your mileage may vary. As far as I can tell the "movie" and "dialog" modes have EQ effects that are either "V-shaped" or vocally enhanced respectively, whereas the "music" setting is a flat EQ. All of the DSP settings still obey the bass/treble controls too. Both the bass and treble controls center at 0db with a clear click point. Turning the control left creates a negative tuning effect, turning them to the right obviously creates a boosting effect. Just judging from my semi-trained ear, they seem to tune +/- 6db db at 120hz and 4.5khz, at maybe 1 octave wide, so nothing extravagant.Overall I'd say you could spend 3x more than $80 to get anything that performs as good or better than these, so price per dollar wise these are an extremely good value.
