No issues- very good quality

I have purchased several mediabridge products in building how home theater setups in multiple houses over the years (I have a bad habit of moving after I do all the crawling through attics and crawlspaces to run cable and nice wall jacks - LOL) That said, I'm very happy with this Mediabridge 14AWG 2-Conductor Speaker Wire (100 Feet, White) - 99.9% Oxygen Free Copper "“ ETL product. I wired my media room for 5.1.2 Dolby Atmos with this wire running through closet, through internal walls and attic. It is both sturdy enough and also very pliable to be easy to work with and the quality of the connection is spot on. I have a Yamaha Dolby Atmos AVR driving an all Klipsch 5.1.2 system with a recently upgraded Center and newly installed in-ceiling speakers. I have finally learned (the hard way) that when you plan that much work running wires, you better make sure the wire itself is good enough quality to be worth it. This one is. I wanted 14AWG to meet or exceed my needs for length of cable run with no signal attenuation. I wanted the purest oxygen free copper I could afford and sufficient shielding for plenum use while still being pliable for out in the room runs to speaker connections. For me, this produce checks all the boxes and I'm happy with my purchase. I will be back for more as needed.... (though hope my moving curse doesn't force that need too very soon) ;) Highly recommended. Buy with confidence.

After reading the few negative reviews I decided I had better check this wire out before going through a difficult installation process. With any item made in China these days, there's that 1 in 1000 chance you get a dud.
Length:
There were complaints about the length not being as advertised (e.g. 80ft instead of 100ft) so I unrolled the spool and measured my '100ft' spool and it was 98ft 9", so not too bad. The jacket is labeled with the CLS rating, etc. but I found it also listed the wire as 99 feet long. So Mediabridge IS indeed misrepresenting and they know it, but not as badly as one-star reviewers claimed. The jacket is white, not off-color and the marking is inconspicuous.
Flexibility:
I found that, for the 16 gauge wire at least that flexibility was good. I didn't expect to get performance here as good as 100% silicone insulation, so I'm very pleased.
Continuity:
There were some comments about intermittent sound being attributed to the wire. I performed a "wiggle" test, bending the wire in a spiral contortion every foot or so, finding continuous connectivity.
Copper Quality:
Some complaints were about tarnished copper. I did not find any where I cut or stripped the wire and solderability was consistent with OFC wire. I measured resistance using a 4-point Kelvin method and found that with a 2-amp source, resistance was 3.83 milli-ohms per foot, beating the AWG 16 gauge solid wire spec of 4.016 milli-ohms per foot.
I am very pleased with my purchase.

This is my go-to wire from in-home installs. Recently ordered 200ft for my 7.2.2 theater area in our new place (25'x14' finished basement) and it was enough to take care of the 2.1 ch system upstairs as well with a little bit of extra.

This wire strips easily, bends easily and the 16awg is thin enough to fit under baseboards easily (even multiple runs under the same baseboard)

I'm not one that thinks wire differences are audible. However..It sounds great, has a nice punch to the low end. Compared to prior installs using cheaper CCA cable, I DO notice that midrange is pleasantly detailed and more precise and it's got crisp high end if slightly muted if your runs are a bit on the long side with the 16awg. Most receivers these days will be able to compensate for the losses when you run your auto calibration or tweak your settings manually however, so that's really a moot point in 2020.

The rub is: As long as you're using OFC (from any manufacturer) you're basically going to get the best sound your ears will be able to distinguish. 80 smackers for 200ft of OFC is a deal and essentially this is the wire I would recommend to anyone about to wire up some speakers.

My wife is ambivalent about my home theater setup and stereo equipment in general. But what really grinds her gears is speaker wires. So when I wired up a Dolby Digital 5.1 surround setup in my new living room, I really needed a way to minimize the form factor of my wiring system. Enter MediaBridge's 14 gauge speaker cable, shrouded in matte white. I was able to wire two bookshelf speakers for stands behind the couch (with cables pinned to the white baseboard molding), a center speaker (on a white TV console) and two floor standing speakers, and she didn't bat an eye. Everything was white and blended in with it's surroundings, she didn't notice"”or care"”about all the cabling. So if you abide by the notion of "happy wife, happy life", go with this product for your home theatre wiring needs.
