These ones are designed for and targeted at computer users and for streaming music from a certain fruit company which makes things that only look good(for some people only).
The price of $800 (you can find them for cheaper, like anything else) is intimidating for the average PC user but for the handful of people who drop a grand just on graphic card(s) without blinking an eye it's a rather good deal if they feel the need to have better audio.
They have good mid and highs, and good enough bass that make most speakers with similar purpose and similar priced name-brand (B whatever..) sounds like *@$!%!.
They are halfway between consumer speakers and *cheap* studio monitors, detailed enough you won't miss anything when playing mp3s while being rather forgiving that lower quality mp3s still sound decent.
They sound quite similar to the bigger LS50 for the mid and highs, but not as clean and detailed, and the bass rolled off way earlier compared to LS50. (Oh what do you want? They are only half the price and does not need anything else to drive them.)
These are good for small rooms and sounds the best when you are close to them, they can get very loud if you turn up the volume but you start to trade quality for quantity when going past ~50% volume.(could be just me)
For their size they almost sounded like bigger speakers, almost.
The line in is from the Left side then connect to the right side through USB. Funny that most PC were placed on the right side, so you have this pull the cable from pc on the right side to the left speaker and another cable back to the right speaker..
There is also a 3.5mm analog input.
It would be better if the volume knob is in front.
There is also a EQ switch ( which adjust mainly the amount of bass ) that is labeled stand/desk. Just use the stand setting unless it is killing your desk.
These ones are good for their price if you factor in the fact that they have their own DAC and AMP.
Not sure what internal DAC it is using, but it is using one for each speaker as they are connected using USB.
