Update 11-22-2018: Very high quality! Helps my Sony SSCS5 bookshelf speakers sing!
Update 12/24/2025: Still the best, in my experience. Just bought some new Sewell Silverback speaker wires with banana plugs for my new set up - after several years of good success with my old set up. They are still truly outstanding with my Sony STR-ZA 3000ES (vintage 2016) and SSCS5 speakers. Update 11-22-2018 re: additional Silverback wire purchased for Sony SSCS5 surround speakers also from Amazon/World Wide Stereo in our newly expanded 5.1 set up: I recently purchased a 100-foot spool of Sewell Silverback 12 AWG speaker wire to install our two new Sony SSCS5 bookshelf speakers as the surround speakers on 36-inch Pangea stands in our nearly all-Sony home theater with STR-ZA3000ES receiver, SSCS5's also at front L and R, SSCS8 for center, and SACS9 for subwoofer. To run the farthest surround speaker required 50 feet of wire that I routed along the baseboards. The SSCS5 is rated at 6 Ohms, so with such a long run of wire, I felt 12 AWG was a safe bet to ensure great sound. For the nearer speaker, I used the remaining 50 feet of Silverback wire. I measured and confirmed 100 feet of wire on the spool, as advertised. Verdict: Success! Phenomenally beautiful, powerful, and dynamic sound from all Sony Core Series speakers, Sony STR-ZA3000ES receiver, and Sewell Silverback 12 AWG wire in 5.1 set up that just keeps getting better and better. Jaw-dropping sound nearing my standard of perfection that I am thoroughly convinced can be attributed to thorough and tedious homework, purchasing the right quality components, and ensuring their best placement in our home theater/den space. Details do matter, as far as I can tell. One of those details, Sewell Silverback wire, is excellent wire in our home theater set up. At minimum, I know that it is of very high quality, and I am certainly confident that the stunning sound we are hearing is the best that we can possibly get from our extremely capable Sony and Sony ES components. No doubt about it. Original review re: 6-foot lengths of Silverback wire with banana plugs: Great product of high quality that I highly recommend. The Sewell Silverback 12 AWG cables fit perfectly and work great with my Sony STR-ZA3000ES AV receiver and Sony SSCS5 bookshelf speakers on 31-inch stands. The highly-regarded and renowned Core Series speakers sound great anyway, but with these excellent speaker cables in the audio chain, they just sing and sing again like there is no tomorrow! I believe it only stands to reason that the true quality of these interconnects, including quantity and quality of pure oxygen-free copper strands helps make for true quality in the delivery of the intended sound from the source. The best part is that you can get this great quality at an equally great affordable price. I hope this helps. Cheers!

Stinky, but Well Made.
Yep, they are stinky. Left them in the garage for a week and most of the smell is gone. Keep them cool and out of the heat! Overall, they are well made. One of the cables was obviously opened and used, but it looked and sounds fine. I can't say if they are superior to other cables, but they don't seem to have any audio flaws that I can detect.

They sound great, connect great, make sure to buy 12 ft of cable which is 6ft left and 6 ft right .
Be ware they are really short but my 8 in sub and one front speaker bangs .They opened it up a bit solid connection , I should have gotten the 6 ft 8ft or 10 ft cables though but where i had the speakers it worked and the other cable i have is micca 14 gauge and sounds good not a big difference unless you really crank it . Then you will see the difference .The banna plugs seemed secure and you can always up grade later if you like . GREAT PRODUCT. GET 6 FT IF YOU WANT 3 FT EACH CABLE, 3 FT LEFT AND 3 ft RIGHT . I ordered 3 ft and got 1 and half foot of cable for left and 1 and half for right . I used one for a sub and one for the right speaker until I can get a 6 ft cable for the left front speaker .I have them connected to a Fosi Bt 30 pro with 2 Magnat 6 and half 3 ways 165 watts rms and one Magnat 8 inch sub Its really loud for a one bedroom apartment . I hope this info helps

The qaulity is there....
I was very pleased with the quality of the cables. I ordered 4 10' cables, and I had a similar experience to other reviewers with respect to some the banana plugs being randomly loose when I received them. Can't say I can figure out why this is, as it is simply a matter of just finishing screwing them tight with your hand. I did fully unscrew and remove the banana plug outer casing on several of the plugs to examine how the plug is attached to the cable, and to check out the raw cable itself. I was impressed to find that the banana plug itself is attached to the cable by two separate threaded screws on opposites sides and ends of the shaft, and held approximately 1/3 to 1/2 inch of the exposed cable wire. All of the banana plugs that I opened up were very well clamped down on the wire by these two screws despite some of the outer casings simply not being hand screwed all the way to not rattle, etc. Also, having handled a fair amount of wire and cable in my day, this wire does appear to indeed by 12 AWG as advertised (I've noted reviews of some other cables here were purchasers were skeptical that their product was really the advertised gauge, so figured I'd offer that observation that these seem to be). As for working with the cables themselves, they were easy to get to lay pretty flat once uncoiled, and the banana plugs fit very securely in both my speaker posts (Fluance XL7F tower speakers and Fluance XLC7 center channel) as well as my receiver (Onkyo TX-NR3009). Sound quality was noticeably improved from some older Monster cable that I had been using previously. I highly recommend these cables for the value the represent--the quality is very good and this is overall a very worthwhile overall purchase!

Cable quality was very good. I had to return the product due to incorrect size (customer fault - issue was between seat and keyboard :)

Sound transmission 100% great high and low frequency, Monster powerline was not great everything is great., The better the cable the more you hear no signal loss have also bought speaker cable for my front speakers and wow everything fantastic also for my rear. never write reviews I have to. Am a hifi buff for over 45 years so impressed I assumed the cables were great, now I know

Good cable. Give more body and bass to music. However due to the bodily warm sound treble seems to roll off. Very good for bright sounding speakers or amplifiers as this cable can balance off.

Moving from normal cable to this has removed all harshness from sound, improved fine details and also bass. Excellent
