Bluetooth - bluetooth stereo, bluetooth


This device works well. All those who say range is crap etc simply don't know or understand bluetooth application. If you use it with a laptop built-in bluetooth or a mobile phone, then range will be short because the laptop or mobile bluetooth is for connecting to devices in the immediate proximity to your work area. Thats why it's called PAN - Personal Area Network.



If you want to use it with increased distance, get a class I (class 1) USB dongle rated for 100 meters. You will not have any trouble.



I have validated it first hand - my HP laptop's built-in BT cuts off all the time if more then 2 meters (6 feet) away. My ipod and iphone work nicely to about 5 meters (15 feet). A cheap billionton class 1 dongle doesn't cut off even at 10 meters (30 feet) and a belkin class 1 usb dongle even works at 12 meters (36 feet) with one concrete wall between.



Another advantage I find useful is that it supports multiple device pairing, I just leave it powered and once you 'disconnect' one device you can 'connect' a different one.



The device is powered by a 5V/0.2A universal (100V-240V) adapter and remembers my paired devices even after disconnecting and reconnecting power.



Audio quality is as good as any other A2DP bluetooth audio device. They all use the SBC (Low Complexity Subband Codec) bluetooth protocol which limits bandwidth to 512 kbit/s - which allows to enjoy sounds similar to a 256 kbit/s stereo mp3 file. Old Version of Belkin F8Z492 Bluetooth Music Receiver for iPod and iPhone (Black)

I purchased both the Belkin Bluetooth Reciever and the BluBridge Receiver from two different locations and was going to return the one that I liked the least. So here is a very quick comparison. In the testing I also had one of my friends give his opinion as well. Here is what we both thought:



Belkin Bluetooth Reciever

Sound Quality: Amazing/Excellent 10/10- sounds just as good if not better than standard wired 3.5mm audio connection

Range: 8/10 Line of sight maybe 20-25ft, although I hear that this also depends on your transmitter, I was using Lenovo s10-3t netbook integrated bluetooth and Iphone 3GS integrated bluetooth as source.

Connectability Ease: 10/10, once you have paired it, it stays plugged in to the wall next to your stereo. Example: I turned off my Lenovo s10-3t netbook, the blue light went out on the belkin receiver showing disconnect, I turned the netbook on a day later, immediately I notice the belkin blue light come back on the belkin receiver, and the connect is so fast that the windows 7 startup sound/chime came in through my stereo. Obviously if you connect your computer to a different bluetooth audio device, you will have to later tell it to reconnect to the belkin. But the whole process is super smooth.

Portability: NOT PORTABLE, stays plugged in to wall, this is also a PLUS, because it always stays very ready for easy connect.



BluBridge 3.5mm Mini-Jack Rx - Receiver

Sound Quality: Excellent 9.8/10, wired and the belkin bluetooth sound were slightly better, it was more of a slightly fuller/richer, slightly louder sound with the belkin or wired connection. Note: it is only very slightly better sound. My friend and I could only tell the difference when we used the same song, same sound source connecting back and forth very quickly. In the BluBridge's defence it produces 9.8/10 sound whether on battery power or connected to usb charging.

Range: 9/10 Line of sight maybe 25-30ft, basically I got an additional 5ft of range from the same bluetooth transmitters. The signal did seem stronger, when I would start to reach the max, the signal would break and then regain clear again for 3-4 more feet if the transmitter was stable. With the belkin as soon as the signal started to break, the signal was gone.

Connectability Ease: 8/10, this is mainly because the unit has a battery power saver that shuts off the device when not in use. So you have to hold down the button on the unit for 7 seconds, then connect with your device (Iphone 3GS or Lenovo s10-3t netbook)

Portability: Extremely and Easily Portable 10/10. I use it off of battery power mostly, I have it plugged into my Harman Kardon Go + Play High-Performance Portable Loudspeaker System with Dock for iPod (Newest Model) which can also operate off of battery power (8-D-cell batteries). Makes for a excellent portable sound source.



Testing: Used the Belkin RockStar 5-Way 3.5-mm Headphone Splitter (White) with Harmon Kardon Go and Play, 2 computer inputs, Belkin bluetooth input, and BluBridge bluetooth input, and Logitech Z-2300 THX-Certified 2.1 Speaker System with Subwoofer. Everything was connected at once and audio was crystal clear, from anysource, this really speaks volumes for the Belkin rockstar. And if your wondering, yes I did play the movie "Gone in 60 seconds" from my HTPC throught the belkin rockstar outputing to both the Logitech z-2300 speakers and the Harmon Kardon Go and PLay at the same time, sounded really good.



Before Very Close scrutinizing side by side testing, I thought I was going to be returning the Belkin, because the range was about 5ft less, and it wasn't portable. And playing with them separately 20min apart I nor my friend could tell a difference in the sound Quality, so it is very slight. But I ended up keeping them both. I recomend the Belkin if you have a stationary high end stereo system and have no need for bluetooth portability with your stereo system. Other wise I recomend the BluBridge 3.5mm receiver if you think you might ever want to hook it up to portable stereo. The Ease of connectiblity at the end of the day with the belkin is what made me keep it.



They are both EXCELLENT PRODUCTS, read details so see which fits your need better, I found a need for both.



PS: at the end of the testing my friend said he is going to buy the BluBridge bluetooth receiver, he like it because the sound quality was still excellent, it was portable, and he liked the look of it. - Bluetooth Stereo - A2dp - Ipad - Bluetooth'
