$10 mediabridge cable sounds better
923166
This cable sounds warm, and presents boomy bass, that I would've been fine with if only it didn't make the music less clear. A $10 media bridge cable sounds more clear, but it is a little harsher. The aq cable sounds more smooth and less harsh, but I just hate the fact that it's not as clear as the $10 media bridge cable.

I had to search through the one-star reviews to find someone else who had the issue I have with this cable. The problem is that once I have my headphones fully seated into the female end of the cable I only get a poor mono mix. I then have to pull my headphone jack back out about 2-3 mm from the end in order to finally get stereo sound. I've found this to be the case no matter what device I use as the audio source (PC, car, iPod, phone etc) it's always the same.  The cable is so cheap that it's not worth returning which is another frustration.  Oh well.

Decent DACs at a rock bottom price. Inexpensive alternative to lousy built-in sound on computers, laptops, and other portable devices.

Muddy sound on a Hsu research sub. Replaced it with a much more expensive Wireworld sub cable and there was a tremendous improvement. Then I tried it on a Lava sub and it worked better so I kept it. If you sub goes sub-subterranean and you like it loud for movies you can do much better than this cable. If you sub rolls at 40hz you may like this product.

My cable worked fine, they did not wiggle or come out of the ethernet ports, however, this is far from "the highest quality" the cable jacket is thin...and I mean THIN! I've previously bought the majority of my cables from mediabridge simply because they have solid thick jackets, and appear to be more along the lines of "the highest quality". I tend to be rather picky about my Cabling, and this will get the job done, but it will rip or tear easily down the road and I do not recommend this cable.

This has a 3.5mm audio jack, Hero 3 uses micro-USB. The adapter cable it about $20 and being a cable would mean a rig to hold it from flopping around (in other words will not seat as pictured). Picture looks better than actual device. Looked like a cat toy with a 3.5mm cheap plastic swivel plug. Looks like someone took a stuffed animal, cut the fabric, applied glue to the material and glued it around a $1 store microphone.
Since it doesn't attach to the Hero 3 was unable to test quality through the gopro. However, did plug it into my laptop. Holding it in the air and using sound recorder (set to default) heard a lot of background noise (hissing). To be fair, fan was running on low 6 feet away from me and it did pick up my wife and daughter talking in the other room.

I am a bit of an audiophile and purchased MDRZX100/White for a non-music related work. I also wanted to buy something very cheap so I don't need to worry about losing it or getting it stolen.

The sound quality is not impressive. Sounds just like what you would expect for a $20 headphone. It is better than sub $10 headphones, but nothing more. I don't mind this, however it is not as good as other reviewers claim.

The cord length is about 4 ft, which is somewhat short. It is good length if you're connecting it to a phone or a laptop (something that is right in front of you). However, if you want to connect it from some device that is further than that, you would need an extension.

This is an ok audio solution if you're looking to improve the sound and clarity of dialogue. The audio quality is good but its seriously lacking any kind of bass. As i said voices sound clear and audible with this but if your watching anything other than the news there are much better cheaper solutions. Any decent sound bar in the $200 price range that includes an easily hide able wireless subwoofer will blow this out of the water for movie watching and music listening. I also own this http://www.amazon.com/Sony-HTCT260H-Sound-Wireless-Subwoofer/dp/B00E3AKF1C  and there's really no comparison. It's like being in a theater with the sony.

Very noticeable reduction in sound quality. Try comparing the sound quality of what you're listening to through your headphones connected to this, and then to your headphones plugged in directly to the origin. It's an awful muddying of fidelity that I can't stand even as a casual listener who cheapskates with $5 headphones and could care less about expensive audiophile equipment.

It's so cheap with free Prime shipping you might as well try them out and then just throw them away if you hate it (which you likely will), and on the off chance you can stand listening to your music through a busy woodworking shop you can keep them. Otherwise stay the hell away.

You get what you pay for in this case. Given the current state of home audio this EQ is better than nothing.

Sound quality is not great and av jack for speakers are even worse.

Not much range beyond 10Khz, Comes with a strange adapter to connect the microphone and a pair of wired headphones to a smart phone. Not sure what app would allow me to hear the mic and the headphones at the same time with the adapter.

I'm frankly kind of amazed. I thought for 30 bucks I'd get a decent spare cable for my 535s, and the specs are better than those of the Shure stock cable (they aren't published, but a salesperson tracked down the info from Shure for me). This cable looks and feels pretty cheap, perhaps because it's clear, very thin, incredibly lightweight, and looks like the plastic fantastic. Disappointed, I sat down to test it. I put on some well known tunes that I've recorded hi rez from vinyl and listened, first with the stock cable, which sounds pretty good. I left all settings on the player except for re-cueing the tunes, swapped cables on my earphones, hit play, and BAM! I literally jumped. I knew the impedence on this cord was lower than the stock but I was not prepared for the flood of sound waves that came barreling through these tiny OCC wires. Time is kept in my tune of choice by the beautiful plucking of a double bass - the difference in that bass with the Mekoko cable was remarkable, pronounced, and immediate. It was bigger, tighter, fuller, more realistic. There's just more there there. Mids were warm and fluid, and highs caught air. Interestingly, there is some nasty sibilance in a couple of spots of this recording; it was tamed through this cable. I'm just blown away. For $30. I spent $300 on a replacement solid silver cable for my Audeze LCD-3s and heard nowhere near this kind of improvement. If you have Shure earbuds, you need this cable. It's just that simple. I just hope the thing lasts...

I'm using the cable for connection of my desktop to my audio receiver in my study. The signal level is poor, and audio range seems limited. I don't know if it's my sound card, the length of the cable, or both.

First of all, if you hadn't noticed, this adapter is mono, so it's not good as a headphone adapter. Second, it drastically reduces the sound quality. Spend a few bucks and get something nicer.

The 3.5 mm connector broke in half when I was removing it from my computer's headphone output.  At first I was super excited because the cable is detachable and I thought to myself that replacing the cord will be a cheap and quick fix.  I was so wrong. In order to get the exact replacement cable, you have to buy it from Sony and it costs $135.00. Why does it cost so much?  Because you can't replace the detachable cord with an aftermarket equivalent because Sony uses their patented "UniMatch" technology which is a way of simply taking a regular cable and surrounding it with threading so that the standard 3.5 mm connectors will not work. While this technology claims to make the signal stronger and therefore, make the sound clearer, you certainly can't hear the difference. If really good sounding non-professional headphones cost a maximum price of $150, I would price these at about $175-$200 as they sound marginally better, if better at all.  The problem is that these cost close to $300.  I am a a home studio producer so cost is something to take into account, but in this instance, I got burned trying to save some money.

This is the first Mediabridge product I have bought that I had a complaint about. The RCA plugs have a metal jacket that makes them VERY tight in the female RCA jacks I've tried them in. Next time I take them out, I'll prob separate it a little with some pliers.
