Question: Does this include all cables you need to hook it up, or do you need to buy additional cables?
Document: USB with digital-to-analog is, however, much different that the familiar speakers, in which any digital-to-analog (D/A) conversion is performed in the computer, and the analog signal is passed through cables to the speaker. With the USB speaker, the audio samples are sent over the cable to the speaker digitally, and a D/A in the speakers converts the signal to analog. This presumably has two advantages.
If you plug your computer and peripherals into a UPS as I do, you will find that wall warts will block the neighboring plugs. Kudos! Although I did not measure them, the power supply and USB cables were of an adequate length. My PC sits on the floor next to a standard sized desk with a UPS in the center and below. Everything reached with room for me to pull out the computer to see what I was plugging in to.The main thing: The sound is impressive.
Definitely audiophile quality sound.Over all the speakers are good speakers and could of have gotten 5 out of 5 if they make good plugs for the speakers like corsair did. But having A+ speakers and going epic cheap on plugs and cables makes these speakers loose 2 stars on my review. To give you and idea of how cheap the cable is the 3.2mm jack cable they provide is a joke, it is flat thin cable like a ribbon which has nothing to protect from picking up static noise.
. The right speaker has the amp in it, so you plug it into your house current, and then hook the left speaker to it, and plug it into your USB port. Behind these three plugs, is a little plastic cover you remove to access an RCA jack for a subwoofer, an 1/8th inch input for analog sound, and an input for OPTICAL AUDIO.
In order to use the Sonos through the Digital Optical input you will need to disconnect the USB option. Sorry for the inconvenience. ****Bummer!Otherwise its a great piece of engineering - tall speakers with a footprint that is really small and great sound.
They simply need to be heard to be believed. But the bottom line is these speakers have made me more excited to dig deep into my iTunes library than I have been in years. They produce sound that is wonderful, rich, and probably without par in the desktop speaker market.A professional review can be found at: [...] (I have no affiliation whatsoever with that site.)
Like the other reviewers, I agree that the sound is great. I wont say its superior compared to the similarly priced audioengine a5+ or the bowers and wilkins mm1, but its great nonetheless. The bass is fantastic.However there is a major input issue- apparently the three inputs are not &#34;switcheable&#34; - you really need to choose one out of the three.
Bass is not a major concern for me, is what I'm saying. Not that I have any reason to think that these guys can't deliver bass, but I don't need them for any dance parties.Basically, these are the best-sounding speakers I have ever owned in my entire life. I've used them for some casual gaming as well as music, and that was particularly great because they do completely envelope you when you're sitting at the desk.
However, if you're using these for stereo speakers in the living room, you're going to be limited to speaker placement. (I don't recommend these for room stereo, as they are clearly designed for desktop use. )2) The speakers don't automatically power off, so you'll need to remember to hit the off switch each day when you're finished.3) The price. I think the price point is a bit high when compared to comparable speakers in the field.
I really don't see a need to add a Subwoofer! I called the DT customer service number & they suggested using a lint roller to clean the speaker grill cloth. They were very friendly and helpful.Lastly, I purchased the speakers on a day Amazon had them listed for $349 but I would not hesitate to pay the $399 MSRP. This is one purchase that will not generate buyers remorse!
Answer: It includes all cables, but the USB cable is short and can be problematic.
