This is the only 3.5mm connector I've found that fits my iPad Otterbox.  The cable also has a well-constructed feel to it... I think it'll last.

Works as intended. Eliminates the need for a 3.5 mm cable that constantly breaks.

USB is a widely adapted standard and yet manufacturers ignore the specs -- and unfortunately many manufacturers of 3.5" drive bay card readers chose to ONLY support this NON-STANDARD 2x10 pin kind of connector instead of a real USB3.
So I'm glad I found this cable -- it is far from an elegant solution but finally I have been able to hook up a 3.5" drive-bay with USB3 4xhub + multiple CF-reader with my MoBo's standard USB3 port.

Despite the extra price for this adapter, the combined price still was lower than the Silverstone solution with the "correct" USB3-A connectors.

The end that's supposed to plug into your audio devices is too short for my Galaxy S7 /WITHOUT/ the case on. All of my other audio cables are 1 millimeter longer than this connector and they all connect cleanly with a nice click. Sure it works in other devices that don't require that extra millimeter, but for what I bought it for, it simply doesn't connect.

The 3mm T handle measures out to about 3.5mm and is not usable.

I keep buying and returning these adapters, hoping one will work for both two stripe and three-stripe headphones. This one works. I had to track it down to buy more because the other ones I've bought all suck.

Plug seems made well and works in my situation which is to reduce my standard 3.5mm headphone cables to fit my Sennheiser 2.5mm plug. It worked OK but only slight movement would cause the sound to drop out! I tried multiple cables, all with the same result! The 3.5mm female side is a little loose fitting causing this. I couldn't sit still enough to keep this from happening! I got a refund since it hadn't arrived by Amazon's estimated date. It finally showed up a week later.

I bought this specifically because my canon rebel t3i camera needs a mini usb cable, and everything else in the world uses micro usb cables, and I didn't want to have to keep a one-off mini usb cable hanging around. but this adapter just does not seem to work for my camera. the adapter works if I connect a western digital external usb hard drive to my computer with it. but my computer does not see the camera if I connect the camera with this adapter (and a known-good micro usb cable). I thought maybe it was the length of the metal sticking out, but I have other cables with the exact same length of metal, and the camera works fine with them. I can't tell you why this one doesn't work. but it doesn't.

Read various reviews stating these work well with 2.5mm headset jacks for Panasonic phones, but alas, these plugs don't seem to work well with my particular phone. The 3.5mm headphone jack is fine, but the 2.5mm plug to the phone is loose and inconsistent, only if I hold the adapter plug just right will it consistently connect. Maybe it's not quite up to industry tolerances for 2.5mm plugs?? At least not up to Panasonic's own headset specs; the Panasonic headsets I have work flawlessly with their plugs.

My Galaxy 5 output takes a 3.5mm plug with 4 sections and therefore would not work with the standard 3 sectioned 3.5mm plug input in my car stereo with just a regular 3.5mm male to male cable. This is the exact cable I needed to plug into my Galaxy 5 and convert to a standard plug. All other descriptions I saw just said they were extentions. No mention of converting but this seller did and they work just great. My car rocks now.
Some buyers complain about mics not working with this, that is because it reduces the number of connections internally from 4 to 3 so there is no connection to run a mic. Generally it is for music applications.
I bought 2 and I believe when I'm done with this review, I'll get a couple more so I'll have plenty on hands. Hey, at this price you can't go wrong.

The molded housing is better than the other similar brands I've found thus far. Though the connectors are pretty good too, they are only really appropriate for solid conductors and not for stranded. For a plug at this price point, not having proper compression connections for stranded conductors (which work equally well for solid) is unacceptable really. Are you listening Interpower? So if you are using stranded, tinning these first will give you a very good connection, which will be much better vs. not being tinned.

This is the C15 model, but if you don't need a plug keyed for C15 and want to save a few bucks, order the C13 model which is identical otherwise. Unfortunately Interpower currently only offer these angled in just the one direction - wish they would offer their C13/C15 plug connectors in both left-angled and right-angled. However, with that said, the majority of devices that would benefit with an angled plug, this plug will most likely be correct. For those remaining devices, it's usually pretty easy just to undo the two screws on the device's power receptacle and and rotate it 180deg.

Only Works good with the 3,5mm conector.
USB and Bluetooh are very buggy, the bass stop to work and i only hear some sound from the left side.
Don't Worth the try guys, if i wanted a wired headphone i would buy one.

Well it works, but...

1) The connector, it's a flimsy proprietary-to-usb cable, can't use any other Mini-USB cable for example.  Also the slightest nudge and it disconnects, I've hurt myself now a few times with this...

2) Why do they need 569MB for Drivers and software?  Just give me the drive rather than make me reformat this...

3) Speed, seems slower than many other drives I've had...

In short I wish I'd bought another drive...

EDIT 03/08/2010: This is actually a Micro-USB connector, not a proprietary one.  Fair enough but it still doesn't fix the fact that I breathe on the connector and I lose my connection.

I'm comparing this to the 3M brand connectors of the same type.  These arrived quickly, no complaints there.  All of the connectors it seemed had no goo in them for insolating the connection.  Even the ones that look as if they hadn't "leaked out" lack sufficient goo to insolate.  There was no goo to evidence leakage into the bag by the way, it just wasn't there.  With the (only slightly more expensive) 3M brand connectors there was no conflict here.  In fact most of those had an excess of goo that would squirt out around the insolation.  Good stuff.  These: not so much.  The little red caps were very brittle as well and popped of several connectors while wrestling with them to get the wiring to fit well.  They list these as 18 gauge compatible but realistically you're going to find yourself spending more time trying to get 18 gauge strands to fit under the connector teeth then you would have spent meticulously soldering and shrink wrapping.  I should have listened to the other reviewers about the goo problem and infered beyond that an over all lack of quality.  Now I'm out ten bucks and left with a bunch of cheap worthless do-dads.  I soldered the thirty or so connections for my stereo harness and threw these out.  Junk

finally, a connector that won't break in 3 days.
solid construction - though the knob does get a little stuck.

GEEZE!  It's just a cable with a very popular connector.  How could you screw this up?  There is a little tab on the connector that keeps if from inserting into the phone.... Galaxy S5 or Galaxy S7.  FRUSTRATING EXPERIENCE!
