Successfully eliminated buzz from Samsung Galaxy S7 phone. I think the audio balance may have shifted (less bass), but an equalizer adjustment seems to have fixed it.

Proof this goes on pretty invisible:
Today I had a coworker that has an S4 too & he's got a protector on that makes the screen fairly cloudy & rainbow artifacts all over. I handed him my phone to show where I dropped it & before I could say anything he says "man, looking at the clarity of your screen, I want to rip off my protector" . . . then I let him know I had a screen protector on there! He was in disbelief & asked for a link.

I agree with the other reviewer that said be careful lifting off the top layer because it WILL peel up the protector. Ask me how I know & why I've only got 1 protector left from that package?

My technique:
1: position protector on the phone and align
2: once aligned, put 2 thin strips of tape at the top from the protector to the phone, anchoring the alignment
3: now the protector will "hinge" at the tape & you can begin removing the adhesive side
4: slowly peel & apply & remove any particles that appear as film adheres to the phone
5: once you completely remove the protective film, stick about a 1/2" back underneath so you can get the last imperfections out

The clear card included in the package really helps you see the bubbles as you try to remove them. I use doubled over scotch tape to help remove particles. Works for me.

I really like these protectors. The start out sticky & get slicker. Really happy with the image quality. Definitely recommend.

Had a big problem with buzzing when playing mp3s on my computer through my stereo tried one from radio shack got rid of the buzz, but lowered and muffled the sound.
This one gave me great clear sound with no buzz.

I had a crazy annoying high pitched ringing sound coming from my car stereo when I would play music off my phone via aux. Not only did this fix the problem, but it increased the sound quality. It's pretty small and discreet, and was super easy to tuck away.  Great product.

Like others I've found in online threads, my S7 is terrible at getting signal. I can be standing next to other Verizon customers and they have a great connection and I have next to nothing. I'll be in my house and suddenly I have a voicemail, yet the phone didn't ring and does not show a missed call - I can call out since I use the advanced (wifi) calling feature. I am about to put my old S4 back into service and use this as a camera and music player. A complete waste of money.

This case doesn't have any obvious defects, but I have a couple of metallic credit cards which may have interfered with voice transmission quality when trying to talk on the phone.  Folks kept telling me I was breaking up and I had 5 bars of signal strength.  Take the phone out of the case and ... Voila!  Voice transmission back to normal.  Also nobody tells you this but you have to open your wallet up all the way to take photos.  I didn't care but I can see how some might find it annoying.

If you hear buzzing in your speakers when you try to charge your phone and play music on your AUX port this is the fix!

Works really well to protect phone, but muffles audio. Negates the use of phone as a phone.

Phone is good, but the charger has wired buzzing sound once plugged in.  I ended up using a different charger that I have around the house. I bought it for my daughter, she really does not need a smart phone to distract her, so this simple one should do the job for calling and texting.

UPDATE 7/27/16: I'm updating my review to four stars as it appears Samsung has resolved a majority of the connection issues in their more recent phones. I'm currently using with a Galaxy S7. There is a bit of lag between the phone and display, and the connection is occasionally interrupted, but overall this setup works well. I would not recommend this for gaming. But as a wireless solution to AppRadio, it does the job. Four stars.

This review is focused on using All-Share as a wireless in-car solution for Pioneer's AppRadio (or any other radio using HDMI connection). I have the All-Share Cast hub hooked up to a Pioneer AVH-X8500BHS, powered through the USB2 port. It is paired to a Galaxy Note II using the Sprint 3G/4G network. I use it mainly to stream Google Maps, Waze, Pandora, Maxthon browser, and YouTube. The assessment below is after 1000 miles of use.

Pros:
- Truly "wireless" solution. Get in, start the car, start the AllShare connection, then put the phone away.
- Connection process is one touch on the Note II from the notification screen.
- Efficient. Smartphone screen turns black when playing video; can stream audio while screen is off.
- No interference to GPS or cellular signals. When using the Samsung 11 PIN MHL adapter, I found the phone got REALLY hot and produced almost no GPS signal. Changing over to the All-Share solved this problem. It should be noted that some head units have external GPS antennas to get around the signal loss. Mine does not.
- NO HEAT. As many of you know, heat kills smartphones. All-Share runs relatively cool and uses less energy than a direct MHL/HDMI connection. May not be an issue depending on how much you drive.

Cons:
- Slight loss of audio quality. Even with Samsung's software update, there is a slight loss of definition in the high and low frequencies. You'll want to ensure the output on your phone is set to "surround." Otherwise the output in "stereo" is flat and tinny. If your audio is REALLY bad, you can try forcing the phone to stream at a higher bit rate by inserting/removing the headphones while All-Share connection is active. I have only had to do this once.
- LAG. I find when streaming maps or YouTube alone, the connection is just fine. But when streaming maps on satellite mode in conjunction with iHeartRadio, it has a tendency to lag, followed by a brief "hiccup" to recover the connection. Pandora works OK but tends to have at least one hiccup every other song. It appears to be related to all of the wireless protocols that can happen at once. At any given time, the phone is running a 3G/4G signal, Bluetooth, All-Share WiFi and GPS.
- Start-up time. Wait 20 seconds after starting the car, initiate the All-Share connection, then wait another 10 seconds for the connection to complete. Only then are you good to go.
- Interference with other WiFi connections. You cannot connect to both WiFi and All-Share at the same time. Doing so will cause instant lag and an eventual loss of the All-Share connection.
- Random connection loss. I'm at the point where I know what will trigger the connection to drop. As mentioned above, the cellular, GPS and bluetooth connections can bog down the phone when All-Share is active. Best to clear the phone's cache prior to initiating All-Share.
- Expensive. For 70 bucks you're getting a wireless HDMI connection only (and a lot of "bugs" for the common user).

- **Not root friendly. Not blaming Samsung but will mention for those interested in using AR Liberator. As most of you know AR Liberator allows full unrestricted use of a rooted phone on the HU screen. The problem is that many users are reporting that All-Share may become unstable when rooted. To date I don't believe folks know why.

At a glance:
- Ease of use: 2 stars
- Performance: 3 stars
- Efficiency: 4 stars
- Value: 2 stars
- Overall: 3 stars

Bottom line: If you can tolerate the occasional audio "hiccup" and .1-.2 second lag, this is an efficient (abet expensive) solution to the 11 PIN MHL adapter for AppRadio. Not ideal for AR Liberator or repeated high bandwidth streaming.

The sound card works fine when just using speakers, but there is a buzzing sound when using headphones. You can mostly drown out the buzzing when audio is playing, but it's quite obnoxious when there is silence. If it wasn't for this issue I would have given it 5 stars. Installed easily on Windows 7 32bit and 64bit.

I was a bit frustrated at first due to an annoying buzz when using this. Found out that I can use a ground loop isolator (~$10) and it fixes the problem. I've been loving this ever since!

Works great. No noise at all when I use this noise isolator. My phone (LG V20) would cause a buzzing noise when I was charging while playing through my car stereo. Not with this isolator. No noise at all.

This little puppy did the trick!  For the past 2 or so years, my TV has had a fairly loud audio hum when hooked up to a Dish Network or DirecTV receiver with the component + red/white or yellow/red/white (analog) cables.  I was also getting strange horizontal lines that would pan vertically.  The only way I could get rid of everything was to move in my high def TV and hook it up with a digital HDMI cable, but that wasn't a permanent solution as the TV was kept in another room.

I had tried just about everything to remedy the problem... from plugging everything in the room to the same outlet to running new cables from the dish.  I was then told that my problem sounded like A/C hum.  So I did some research and came across this gadget.  Like several others have mentioned, I too was skeptical at first thinking that this couldn't solve my problem.  However, since I tried just about everything besides having an electrician come to my house, I thought I'd give this a try since other reviewers mentioned it fixed their similar problem (thanks by the way for everyone that posted those).

Here's some good usage info.  My first attempt at using the Hum X failed miserably.  I plugged it into the wall, plugged a power strip into it, and then plugged my TV and satellite receiver into the power strip.  HuMmMmMmmMM--it was still there!!!  So then I decided to unplug my computer and other gadgets that were connected to other outlets in the room, and to my surprise both the audio and video hums were gone!  I then thought... "Wait a minute, maybe if I unplug the Hum X now and just plug the TV and satellite receiver into the power strip and leave everything else in the room unplugged then all would be good."  But nope, still had the hum.  So I plugged the Hum X back into the wall and all was good again.  I then plugged all of my gadgets into the power strip connected to the Hum X and the hum was still gone.  Yay, great product EBTECH!

The Hum X seems pretty expensive to me; but since it works and has fixed a long-time irritating problem that nothing else seemed to fix, I am totally fine with paying $63 for it.

The first thing to fail on every cellphone I have ever owned is the USB input. This keeps my S7 from having to plug into a wall outlet. Sure, this is not cheap, but it is cheap compared to the cost of a new phone.

This case caused all kind of problems with my Galaxy S4.  Echo when talking, static, lost signals, it does not work.  After removing the Case, the phone worked fine.  Waste of money.

very glad to have found a way to keep cell phones away from the brain.  So far, the gadget is working just fine.
