Koss HB60 Infrared Clip-On Wireless Headphones Review

Koss HB60 Infrared Clip-On Wireless Headphones
Average Reviews:

(More customer reviews)

The best part of the Koss HB60 is that you can plug any standard headphone jack into the infrared receiver. Thus, with the HB60 you can convert any of the headphones that you already own (and love) to wireless usage.
The worst part about the Koss HB60 is the headphone that it comes with. This thing is designed to be clipped onto your ears, and boy, do they hurt after about 5 minutes! These headphones also have a very strong high frequency boost (which seems to be the standard "Koss sound" - headphones for people with high frequency hearing loss). If you have never listened to Koss headphones, you might think that this hissing sound is due to poor infrared transmission. IMHO, Koss should lower the price of the Koss HB60 and just sell it without this bad headphone.
When I plugged my two Sennheiser headphones (HD545 and HD570) into the Koss HB60, they both sounded great! I can't tell that there is much difference between plugging these headphones directly into the computer/player versus plugging into the Koss HB60. There is very little hissing noise with the Sennheiser headphones plugged in as long as the receiving unit is facing the transmitter directly and located less than about 8 feet away or so. Turn the receiver to face another direction and the hissing increases only slightly, as the receiver picks up the reflected signal off the walls of the room. Step out of the room, or go to a part of the room where the transmitter is not sending any infrared beams, and the signal is completely replaced by static.
The Koss HB60 amplifies the input signal quite a bit, about 4-5 times as loud. This is great if your input signal is fairly weak, such as can happen with some cheap CD players or computers. However, because of this high gain, the amplifier of the Koss HB60 will saturate on the louder pieces of music if you set the input signal strength too high. This will sound like bursts of irregular high frequency static coming through. However, if you set the input signal too low, then there is a slight increase in the hissing sound.So you have to adjust the input signal carefully.
The only really annoying thing about the Koss HB60 is that the belt clip is located directly over the cover for the two AAA batteries. However, the clip is detachable, which, as I only discovered recently, is the real trick to changing batteries on this thing - pull the belt clip off first!
So I took off one star, but otherwise the Koss HB60 is a fine product as long as you understand the inherent limitations of this form of wireless transmission.
I got the Koss HB60 because I wanted to listen to headphones while stringing tennis racquets.I do the stringing in our family computer room, so I can't use the computer speakers most of the time when others are working in the room. The racquet stringing requires some moving around, but mostly I am standing facing in one direction. Thus, I can clip the receiver to the collar of my shirt so that it mostly faces the transmitter. Before, I had plugged the Sennheisers into one of the computers in the same room through an extension cord. This long line was always very messy and easy to step on or get entangled. I ruined at least two of the Sennheiser headphone cords in this fashion by stepping on them and jerking them until they developed an internal break in the wires. Now I can listen to the Sennheisers without worrying about the cord.

Installed in a '02 RSX. Very solid product. The hinge has a quality feel to it. THe screen is bright, contrast and color are good, sharpness is average. The LED lights are ok, but make for poor dome light replacements. The resolution is average, with picture quality being better than expected.
For the price, this is one of the better displays available.

After installation, this screen worked for one day, and then stopped functioning. The power turns on, but no video will reaches the screen. I tried to troubleshoot the problem but it looks like I got a lemon. I didn't have time to try and return it, since we had vacation plans and had to go on our road trip without our new screen!

Coby CA-745 Wireless FM Car Transmitter with Digital Display and DC Car Cigarette Lighter Adapter Review

Coby CA-745 Wireless FM Car Transmitter with Digital Display and DC Car Cigarette Lighter Adapter

The Coby-745 is in my opinion, the all-around best buy in the wireless FM car transmitter market. At $17.99 on Amazon, it is roughly half the price of most of it's competitors, but what's amazing is that it provides additional features! The cap on the built in car charger flips off to reveal a spot for another charging plug (like for a cell phone for example). The springs hold the device in tightly while in use and the charger unit is hinged to the transmitter, providing for a 360 degree+ rotation of the unit. The light up screen in blue shows the full frequency channels you can select from with the lighted dial, in increments of 0.1 MHz.
This unit doesn't just look pretty and have nice features, it also performs extremely well. On a 40 minute commute through back roads, highway and city, the unit didn't lose signal once and I heard ZERO interference, yes, that's right, none! Compare that to other reviews.
Downsides? All the downsides are common to most other transmitters: it doesn't have an on/off button, so you have to unplug the unit if you want it to stop drawing power. To get the sound just right, you have to crank the treble on your car stereo a tad (although this just may be a personal preference). And, you have to crank the volume on your mp3 player and/or stereo (and remember to turn the volumes back down when you use your stereo or mp3 player without the transmitter or else risk blowing out your eardrums). There was some static noise when handling the unit initially although I found this went away quickly as the static charge (coming from the user) dispersed.
The sound quality amazes me- very near CD quality sound- and I was very pleased there was no interference- in the 40 minutes driving, I never had to switch channels. As long as it holds up, I don't plan on switching transmitters anytime soon either. The Coby-745 rocks.
