Bad for multiple devices
583103
The sound is good, and they work well for running. But throughout a typical day, I use them with three different devices: some of the time with my phone (when walking around), with my tablet (when working on the train while commuting), and with my computer (when working, either at home or at the office). When I switch, there is an 80%+ chance that I need to re-pair the headphones with the device I'm switching to. It's extremely frustrating, to the point where I wish I hadn't bought them. I have a Plantronics Edge headset that I use with all three devices (Nexus 6, Note 10.1 2014, and MBPr running 10.10, in case it matters), and I've never had that problem with with the Edge. So this is definitely an issue with the BackBeat Fit, and not with the paired devices.

If you're only planning on using these with one device, get them. They're great. If you want to use them with many different devices, either be prepared for it to be far from seamless, or get something else.

The adapter works however if you have two USB ports next to each other, the adapter will block the use of the second port.  Therefor leaving it unusable.

Handles multiple connections but does not hold sources very well. Can't listen to audio from laptop and use phone without it switching sources.  Does not switch back without user intervention.  Must only have one source connected at a time to not have disruptions.

If you want to connect your phone or tablet to any other BT device in your area DO NOT buy this. It constantly reconnects even if you are trying to connect to something else. When this device has power and is in range I cannot connect to any other BT device. Find something else.

I don't know if I got a bad adapter, but for some reason mine continuously drops the signal from my router, even when everything else ( my iPhone, my Kindle, etc.) stays connected.
When it does stay connected, it does alright, but having to turn the radio off and on every 10 minutes or so just to get it to connect to my network is a pain.

Also, the driver software for the adapter continuously deselects my active window, which is very frustrating while doing anything online.  If I want to work in Photoshop, I find it is easier to work offline and shut down the software, just so I don't go bald.

If you absolutely cannot afford another wireless adapter, this one will do in a pinch, but if your wallet can support a better one, do yourself a favor and steer clear.

It's pretty good but I couldn't get it to work on two different devices (iPhones).  I use it to turn off my kids Playstation after telling them for the third time to come to dinner :D

Along with the other reviewers here, I purchased this to charge/connect a few idevices and a blackberry (powered) and connect an external drive or two (non-powered).  The USB connection works as expected.  The power does not.
I cannot get any device to charge alone much less two or more.  I have tried all the usual different outlet, cable, one device at a time, etc.  Contacted Targus support, no help.

I do not recommend this product.

As far as I know I plugged it in correctly to more than one device and it did not work. Disappointed, but luckily it was cheap.

Occasionally I'll have inconsistent unusual behaviour from my devices that are connected to it.

I think It could be that since there is no power amp, there may not be enough power getting to all your devices, but I'm not sure.

I bought this adapter to use with my laptop running Windows 10 for a fourth monitor.  It would only display on the 4th monitor and not on the other 3.  And the whole computer would freeze up when I plugged in the adapter, so I would have to restart without the adapter plugged in to get the computer working again.  The driver also messed up my other displays to where they wouldn't work correctly either.  Pretty terrible product.  Uninstalled driver and returning adapter.

This charger works with 1A devices (cell phones, smartphones, etc.) but it actually DISCHARGES 2A devices (iPads, tablets.) The seller also does not seem to offer a return policy for this item under any conditions. I would avoid buying this item and stick to a known, quality brand instead.

I bought this with the hope to share a PC speaker system between two sources with needing to swap connections. Unfortunately this cable only works if:

a) Only one device is plugged in, or
b) both devices plugged in are turned on

Because one device is my primary and the other is something I use on occasion only, this cable really doesn't do what it should. Unless both computers are on I get no sound through the cables until I unplug the device that is off. I looked at similar products on Amazon and saw this was a complaint on other cables, but this one was listed as working for this exact scenario. Be aware if this is what you want, this cable will not work for you.

Meh. The connecter is really bad. If you don't mind having to move the connecter every few seconds due to it losing connection to your device,  I'd recommend getting this. Otherwise,  stay away.

This cable will connect USB devices to my phone, but will not charge my phone at the same time.  I read Sean Dunn's review, and saw the helpful:  "For a device to see itself as charging, a MINIMUM of ~500mA @ 5V (USB 2.0) must be supplied to the smartphone. The Y nature of this cable means that it is splitting the current to the USB device and the smartphone. When you split the current of a 500mA @ 5V charger, both devices attempt to get 250mA @ 5V. This is NOT enough to trigger charging recognition by most devices."

So, to be fair before writing a review, I decided to test, as perhaps I wasn't seeing charging due to peripheral device power draw.  I tried it without any peripherals attached.  No charging.  I attached a powered USB hub so there were peripherals, but they drew from the hub.  No charging.  I took a bit of a risk and used a tablet power supply connected to my phone through the OTG cable.  No charging.  It wasn't simply not registering charging.  I waited to be sure and my phone's power dropped as it normally does when not plugged in.  I tried the cable on a Nexus 7 tablet.  No charging.

I'd return it if I didn't need to be able to connect the peripherals Monday.  Maybe the cable I received was simply defective.  Sean Dunn's glowing and informative review indicates he couldn't be more pleased, but I was deeply disappointed.  Fortunately it wasn't expensive, so trying this wasn't a big loss, and since the USB peripherals do work, I'll just have to find convenient times to unplug them and charge my phone.  While that's better than nothing, it is certainly not what one expects when deliberately buying a more expensive cable so that you can connect USB devices and charge simultaneously.

I do wish I had time to send it back and try a new one.  If GomeBuy wants to send a new one and it works, I'd be happy to try it and change my review--sometimes how a company handles a problem shows more about it than the problem does.

For anyone considering a purchase, I'd suggest you be sure it's not critical you be able to charge with this cable since you may not be able to.

This charges my iPhone just fine, but it can't handle two devices at once without causing radio signal interference. I obviously bought a dual car charger for the purpose of charging two devices at once, and I shouldn't have to turn my radio off in the process.

I purchased this item to switch several devices into a single projector input.  Once installed I received interfence making the HD signal distorted and very poor.  I returned the item immediately.

Doesn't work with most devices I own and when it does work with a device it is tricky to get it to work.  Not worth buying.
