NVX XGLI35

Nice & clean

Working great! I had a lot of engine whine and other interferences that drove me crazy. not as bad through my aux input with XM, but really bad with my phone. Sound is all cleared up now and sounds great with both devices plugged through it. Sound level is raised as well. Nice product, have it velcro ' to the dash for simple use and decent looks.

Works as designed.

I purchased this for integration of a PC integration with a phone system, it worked as intended. Without the isolator, the phone system would lock or reboot, but works fine with this device. I've found many other occasions that it's needed also.

This is a great ground loop isolator. It does a noticeable job in improving signal and minimizing interference! I definitely suggest getting this product when using the 3.5mm connection.

Excellent

Has mostly got rid of the humming noisefrom using a aux cable. I dont notice the noise if the volume is high anymore.

Pretty effective!

This filter was used in conjunction with an XM Radio in my home and it seems to have help filter out most of the radio interference I was getting since my house is located next to a large radio or cell tower.

A waste for me.

I didn't notice any change in clarity or quality of sound. In my opinion it was a waste of money. Sounded like something was loose when I took it out of the box. First NVX product I didn't love.

Perfect

This entirely gets rid of the obnoxious hum/ignition noise on the AUX jack when my device (Droid in this case, but everything seems to do it) is charging from the cigarette lighter in my 2008 MazdaSpeed3, and doesn't appear to degrade the signal quality at all. It just sits in my center console under the armrest and does its job. Couldn't be better. I've had it for six months now and no problems.
