Review: Tinnitus Triggers = Damaged Ears after 30-Minutes - These speakers had a high-pitched whine coming out of them even through they were correctly connected to the same APC UPS as the computer to avoid ground-loop issues and using the 3.5mm jack stereo cable that was kept away from all other cables. Tried the PC jack connection in the back and front of the system, and also my Google Nexus 6P phone jack. Speakers were only set to use 5-10% or less of volume on them and also 15/100 on the PC to avoid the hissing and whining sound that they were emitting but it was still present. I only used these speakers for less than 30-minutes before I had enough and packed them up to be shipped back but the damage to my ears and hearing was done. I started hearing the tinnitus buzzy whine that night when I went to bed and ever since then every day when I get tired. These speakers triggered something in both of my ears that is now causing tinnitus for me anytime that I start getting tired or sleepy. Never had this problem before in my life and I've used dozens of different speaker systems and head-phones in my life, always a very low volume since I have very good hearing. This tinnitus problem has now been with me for a few months and it has not gotten any better. Spoke to my doctor and there is no clear-cure for it, even using a hormone treatment does not guarantee to solve or cure this issue. I fear that this issue might be permanent now, I hope not and that it'll go away after a few more months. I suspect that the cheap electronics in these speakers are to blame and that they sent out some super-high frequency that damaged my hearing. I'm even thinking of going to an audiologist to have my new hearing problem evaluated since I have no other markers for why this tinnitus happened other than the speakers.

## Questions & Answers

**Q: why are they non returnable?**
A: Metra 72-8104 Speaker Connector for Select Toyota Vehicles
This connector does not fit Toyota Venza. Why I cannot return?

**Q: what is the average life span of these speakers?**
A: 7+ YEARS STRONG! I purchased these back in December of 2013 in college. Speakers have moved around over 10 times, but I kept the original box for moving purposes. Finally purchased a home and these still remain as my main TV speakers. I recommend this set of speakers for anyone who wants that movie theater and thrilling music experience in their own home!

**Q: How does one extend the cable of the control speaker with the 15 pin vga cable? a regular vga cable extension didn't work.**
A: The problem with most all VGA Extension cables is that they tie pins 6,7,8 and 10 to the casing (GND). This is fine for a VGA Cable, but is not desired for an extension cable. It does not work in extending the right control speaker.

Instead, go with the Amphenol Cable Extension that wires the pins straight through. 
Lengths are available in 5', 10', 15' and 25'. Just change the last two digits when looking for your desired length.
CS-DSDHD15MF0-005 Length: 5'
CS-DSDHD15MF0-010 Length: 10'
CS-DSDHD15MF0-015 Length: 15'
CS-DSDHD15MF0-025 Length: 25'

Be sure to get a Male to Female connectors.

**Q: what are the speaker and sub dimensions**
A: The sub woofer is 10" deep, 12" wide and 11" high. The speakers are 5"  wide, 5 " deep and 8" high. Meas. are aprox. Hope that helps.
