As mentioned earlier, have to dig them up (packed them up in a box somewhere). I would strongly suggest bringing your audio device to test the USB cable first, as do you not want to end up with another useless USB cable again. May also check the reason for being "picky" about USB cables...
Differences are too many including pricing, brand, appearance (such as color, texture, shape, etc), size (dimensions), weight, features (such as remote control), volume and tone control location, etc. Technically the main differences are...
Edifier R1600T III - Class D (digital) bi-amplifiers
- single power supply
- 4-inch woofers
- 30WRMS per speaker, total of 60WRMS
- Unbalanced RCA inputs only (standard connection)
KRK Rokit 5 G3- Class AB (analogue) bi-amplifiers
- split power supply (each speaker has its own power supply)
- 5-inch woofers
- 50WRMS per speaker, total of 100WRMS
- Unbalanced RCA inputs as well as balanced TRS and XLR inputs (professional grade connection)
Obviously with bigger woofer on the KRK Rokit 5, can expect better low frequency response. That Edifier R1600T III on the other hand is considered as a very affordable high quality studio monitor. Of course, immediately those differences are reflected in the pricing as well (as that KRK Rokit 5 costs about 3 to 4 times more than Edifier R1600T III).
Anyway, here is a review:
Gecid.com Ukrainian IT-portal: Logitech Multimedia Speakers Z240 review that clearly highlights/demonstrates the problem of using single full range drivers. Can see from the frequency response graph the main weaknesses of using a single full range driver as I've already mentioned earlier...

great news! i have replace my cable. i use it from old camera cable. the cable charge and transfer picture to pc.
alright. thanks for the comparison! if i have extra money. i'll bought my krk rokit 5. if not, i'll go for edifier R1600T III.
the low frequency responses on krk rokit 5 and Edifier R1600T III is not really a lot of differences right? since the Edifier R1600T III 4-inch woofer and KRK Rokit 5 have 5-inch woofer?
