Spectacular device for BT audio
924026
So this product is nothing short of amazing (with a few minor caveats which I'll address at the end).  However, in order to really get what makes this thing so incredible is to understand how it actually works, which I personally found a little hard to grasp from the product description.  In fact, calling this thing a Bluetooth dongle isn't totally accurate, at least not in the traditional sense... it doesn't give your computer/laptop direct access to the BT radio via USB the way other dongles do.  What this clever little guy actually is is a **USB audio device** that takes audio output from your computer (the way that USB speakers would) and subsequently broadcasts it over Bluetooth using whatever codec your receiving device supports (SBC, Fast Stream, aptX, aptX Low Latency, or just regular AD2P).  This is the reason the device doesn't need drivers, because it cuts your OS's Bluetooth support completely out of the picture and relies solely on USB audio support, which nearly every OS out there supports.

This is super helpful if you have an older Apple desktop or Macbook that doesn't support aptX, or if you want aptX Low Latency, which Apple has zero support for yet, at least at the time of this posting.  And if you're a Windows user, well, this product simply blows Microsoft's shoddy built-in BT support out of the water!  I myself have gone thru at least 4-5 dongles and never found one that worked flawlessly in Windows; they all had some sort of issue that required frequent re-pairing, power cycling, driver reinstalling, or physically replugging the dongle just to get Windows to play nicely with my various BT audio devices.

Now the one drawback to having a device that works like this one is that you will have no access to pair or see connected devices directly from Windows/OS X; all the pairing is done via a button on the device itself.  But you can pair multiple devices simultaneously, so unless you leave all your BT speakers/headphones turned on at the same time this isn't really an issue.  Also, since it only supports audio out, this will not provide support for the mic portion of your BT headset.  But I don't really consider any of these things flaws, as they're really just limitations of this format.

The only real flaw I noticed is that the range on this is only a little above average.  It's by no means bad, but I have seen better.  But that said, even if your speaker/headphone do go out of a range or there's radio interference, it does a superb job at reconnecting with minimal sputter and with NO added audio delay -- I still remains perfectly synced with the audio source.

All things considered, this is still by far the best Bluetooth dongle I've ever purchased.

This is great!  It adds BT to my old home stereo, with white/red connectors, so now I can stream whatever I want from my phone or tablet through the home system.

This is a very cool little device.  I have been looking for a way to get my music playing through our old Sony under cabinet radio.  It has it's own AUX input but with BT tech so readily available I wanted to utilize it.  I own a BT Nyrius receiver that has been super solid out in the garage so I wanted something like that.  This fit the bill perfectly.  It has a nice small form factor and looks pretty good.  It came with the USB power supply and cord but also has a small battery installed in it.  I will not be using the battery and will keep it plugged in at all times.  I have this stuck to my under cabinet radio with the AUX cable plugged into it.  Now all I have to do is press and hold the button to turn it on and have full control over the radio from my phone.  The distance was pretty good but not the greatest through all the walls in my house so I had to take a star off.  Other than that connecting it was very easy and sound quality was on par with other BT devices I have used.  All in all I am very happy with this little device.  I received this product in exchange for an unbiased review. All of my opinions are my own and 100% the truth.

awesome sound! It connects to all my devices via BT. I can control volume and music from either my smartphone or the jambox. The battery seems to last forever.

I've had this great little device about eight months.  While most reviewers have focused on its use in the car, my application is a little different.  I use my iPod Touch as jukebox streaming my personal music collection and Internet radio (including Pandora, Slacker, etc.) to my home stereo.  Sound quality is exceptional (for A2DP).  Pairs easily (and remembers the pairing).  It does require USB power (not a problem in my setup with HTPC, and set-top box providing ample ports).  So not just for Blackberry (any A2DP device will work) and not just for your car.  A poor man's alternative to the Cordette Gem Digital/Analog converter(compare at $799).  Very happy with this purchase.

This unit works wonderfully to add bluetooth to your car radio.  I had used external FM transmitters for years but was never happy with the results.  I finally got tired of fighting interference and needing to retune to another station and decided to give this iSimple kit a chance.  I'm so glad I did!

Although the iSimple is still technically a FM modulator, it is hardwired to the antenna jack on your radio.  The unit also turns off your existing antenna input when switching to bluetooth mode, so you have virtually no interference with the signal.  The sound quality surpassed my expectations!

I installed it myself and it was my first time attempting any sort of car audio install.  The process took 2 days, but a lot of that time was spent figuring out how to remove my dash and the OEM radio.  Actual install/wiring of the iSimple itself took me about 5 hours, and a lot of that time was running back and forth to different auto parts stores looking for various parts.  I spent around $40-50 in required install parts (2 antenna adapters, a fuse adapter to pull 12V to power the unit, some velcro tape to mount it), but in the end it was so worth it.

My only problem with it has been some strange clipping/popping on the audio of someone talking to me while on a phone call.  It happens infrequently, and I don't think there are any audio artifacts audible to the person on the other end of the conversation, so I'm not sure what is causing them.  It never happens with music, only phone calls and Facetime audio.  I plan on investigating that in the future, but even taking that issue into consideration, I'm still thrilled with the Tranzit Blue HF.

Excellent stereo sound and battery life. The best thing of this BT is that work with any 3.5mm headphone connector. I had try many others stereo BT, but this one is my favorite. Completely recommended!

Love this product! The audio reproduction through the optical output is far superior to other Bluetooth receivers I've owned. It's a good option to have both optical and digital outputs. Sounds great through my Onkyo 5.1 receiver

The sound is amazing, hooked it into my PC and added the digital hookup to my Onkyo TX-SR-505 A/V amp/receiver and wow!  This audio card and speakers are outstanding.  True DTS HD audio and digital to boot.  Installation was a breeze, didn't even have to do any hard labor.  Caution though make sure you have at least 500 watt power supply, mine is 525 watts.  Creative comes with the software to make many adjustments that make listening to music (my thing) or video gaming worth it.  I did not use the microphone input but those that do video talk and such will like that feature.  One small thing; the surround speaker wires could be longer like they were with the 4.1 Creative system but you will not be disappointed with this equipment.  Individual volume control included.  You will need your own optical input cable for your amp/receiver to get the digital hookup.  This is worth it at the price when so much "junk" is coming out of China these days; my apologies, you can't go wrong with this one.  Buy, you won't be disappointed.  Oh, Amazon ships this equipment in a very, very tight protective package.

I'm very satisfied with this gadget.  Paired perfectly with my LG enV Touch.  It handles the switch between music playback and phone use perfectly, without any extra tweaking of the settings.  The microphone picks up well, even at low voice volume.  Provides good audio quality.  I do get some intermittant snapping and popping when using it for stereo music playback, but that only occurs during the pauses between songs, and it's not really a problem.  I slip it over my shirt pocket and wear my phone on my belt.  The earphones that come with it are nice enough, but a little large for my taste; I set them aside and am using some smaller, lighter buds instead.  The range is satisfactory. One pretty cool use that I found for it is to connect a speaker system to it instead of headphones/earbuds--that way I can wirelessly stream music from my phone for the room audience to hear wherever a speaker system with a mini stereo plug input exists.  This application can easily "wow" those who are unfamiliar with bluetooth.  Unfortunately, it can also drain the unit's battery pretty quickly, so be prepared to plug it in to power after several hours of using it this way.  You can also use this technique to create a room-filling speakerphone system during mobile phone calls using the Sonorix.

I love this unit. It provides outstanding audio and video playback. Works very well with iPod cable and with bluetooth. I highly recommend it. I was able to easily install it solo.

I purchased one of these from eBay and have had good results with it. At first, I thought it was a waste of money because I would have to reset the bluetooth connection after every song when playing Pandora radio on my Blackberry Bold. The audio would go from the bluetooth and revert back to the built in speaker. I found out that I had to enable bluetooth within the Pandora app itself to fix this. It worked flawlessly with my Lenovo A1 IdeaPad Android tablet with Pandora and other media player apps. When a call comes in on the Blackberry, you get a tone alert through the bluetooth, and when you answer the call a dialog box pops up and you click to direct the call to the handset. (because this device does not have a microphone) After you hang up, your music resumes.

Range is 10+ meters, with a little interference from microwaves and other 2.4G devices like cordless phones. This is typical and not an issue with this particular device. Batteries last about 4-5 hours and take about an hour and a half to charge with the included adapter.

Sound quality is good. I have used this on everything from Sennheiser over the ear headphones, Altec Lansing PC speakers with subwoofer, and even a vintage Fisher 500-B stereo receiver. Worst sound quality was through an old laptop with a bluetooth adapter, where for some reason it was sounding very compressed. I think there may be a bitrate setting somewhere in the software but this is a problem with my audio source, as this device is capable of high quality sound.

I knocked it down one star because I think the 3.5mm jack should be built into the unit rather than hanging from a cable. I'm afraid that this will eventually be the demise of this device when it gets ripped out by accident.

My "eBay special" did not have any branding on it whatsoever, but the instructions identify it as a "Bluetooth audio receiver BTI-005" and "BTI-005" comes up when you pair it. The one I have is identical to this one on Amazon.

Love, love, love this device.  Solves the exact problem I have (which is having controls for BT audio mounted in the wall of a store space).  Employees can simply use the play/pause, next, previous buttons or adjust the volume without even seeing the audio source.

For the person who wrote about how ugly the back end part is, if you've got the audio out portion in plain sight, this is the wrong BT solution for you.  The audio out portion is designed to go next to your receiver.  Having a power connection inside the device is actually a really bad idea.  Besides needing to make the unit much, much larger to run off 120V directly, you would have to put it inside a high-voltage electrical box instead of the low-voltage (open back) gang box.

I've had it installed a few days now in this commercial space, and everyone who sees it says something to the effect of, "That's so cool!".

I could not be any happier with this thing.

Brilliant little gadget, but requires some tech proficiency, and included USB DAC is poor and should be swapped for something better if you care about sound quality.

Let me first say that I'm really pleased with this device, which is a clever hack on a mini wireless router that turns it into a Linux based AirPlay receiver with the flexibility to use any DAC you want.

However, getting it to work well required some effort, which I think the average consumer might not find simple.

First off, if you hear the words 'telnet' and 'ssh' and 'IP address' and 'fiddling with advanced wireless settings' and start to get nervous, this is maybe not the ideal device for you, at least if you're responsible for the initial setup.

Here was my experience:

 1. Initial startup was a breeze - plug in to power, wait for startup, join the dedicated WiFi network, test AirPlay from my iPhone to the device. It worked. However, sound quality is poor. Crackly and very noisy.
 2. Replaced the included USB DAC with a Sennheiser unit I had, and sound is much improved. I would recommend just purchasing a better DAC along with this device - they're not expensive.
 3. Tried to switch to wireless client mode - and it can't connect to my home network, which uses WPA-PSK. After some trial an error, I discover that it only operates on 2.4GHz (not 5GHz), and that it can't handle a WPA password with spaces or symbols. After setting the password on my 2.4GHz network to alphanumeric only, the device can connect. Yay! I'm able to ssh to it for further config by discovering the IP by looking for it in my router's list of connected devices.
 4. Device is now working, and is super easy to use. All AirPlay compatible devices on the WiFi network can see it and play to it. Great... But there are new sound issues. Lots of skipping and dropouts, which seems like network rather than DAC problems.
 5. I experiment with wired client mode, running an ethernet cable to the device from my router. This clears up the skipping, so there must be a WiFi network issue.
 6. Spend several hours experimenting with different advanced WiFi settings on my router, and googling the issue. Eventually, I get things working well on WiFi. Due to the sheer number of different parameters, I don't know for sure what did it, but on my Asus AC-N66U router running Merlin Firmware, I suspect that setting the RTS Threshold to 2346 (one down from the default) and disabling WMM APSD (a 'power saving' feature, apparently) did the trick.

So, in the end I have AirPlay enabled speakers that work great, for a small dollar price and several hours of my time in figuring out the optimal setup. But it might be worth considering my experience before deciding if this is the right device for you.

This adapter is probably somewhat overpriced, but it's worth it. The sound is true, pairing is reliable, and if you have a Bose with a 30-pin connector but no longer a 30-pin iPhone to go with it (or just want the device-independent flexibility offered by Bluetooth), this is your jam. The Bluetooth reception distance is rather astounding--at least 30 feet through my roughly 40-year-old-home walls. Especially given the non-line-of-sight reception distance and the incredibly thoughtful and user-centric design flexibility, no complaints at all.

As most of the reviews have stated, this device is pretty incredible. I particularly like the Android integration - works smoothly and not much different that n my phone. Access to apps is great and it's just nice to see that they built this fantastic audio device with that kind of interoperability. Spotify works without issue which is nice for me. With a quality set of headphones, the audio experience is the best I hav ever had - not a true audiophile obviously, but I like my music!

The only real downside for me is the bluetooth - underwood that this is not why you have the DP-X1, but still, the range is very poor. If I place it in my front pocket the sound immediately starts to break up.

Overall fantastic and even though a little pricey...it's worth it without a doubt.
