KINIVO BTD-400 Bluetooth 4.0 USB adapter - For Windows 10/8.1/8 / 7 / Windows XP/Vista

Long story short: buy this if you want a headache-free experience with a Xbox One Controller. Practically every bluetooth dongle listed on Amazon uses Qualcomm's CSR8510A chip - with drivers last updated in 2012. Now, the date wouldn't be much of an issue if the damned chip worked with an Xbox One Controller - the latest one that has bluetooth built-in. I tried two different cheap models, and both struggled to get connected to the controller, and would NEVER reconnect - necessitating a full disconnect and re-pairing. Painful. This dongle uses Broadcom's BCM20702 chip, and it works flawlessly with the Xbox One controller (with Windows' default drivers). I'm also using a Logitech K480 keyboard simultaneously and everything works A-OK. Connecting was fast, and everything reconnects in what feels like a second. This is ~4X as expensive, but that's totally worth it, because the alternative just doesn't work properly.

Just awesome. It becomes easy to connect the Bluetooth enabled devices. It supports every type of devices. But if you are planning to buy it for data transfer, think twice. I have checked with several devices that it is not giving more than 1.2 mbps. While you can get more speed even using the cheapest data cables. Inspite of giving Bluetooth 4.0 the data transfer speed is so so poor. The only thing that couldn't make me satisfied. But the warranty period will certainly attract you. Pros. 1) greater range. 2) ease of installation(cd will be provided) 3) greater applicability. Supports almost any type of devices. 4) attracttive warranty period. Cons. 1) the data transfer speed. . .my suggestion- as you r not getting more speed of data transfer, you should move for kinivo btd-300, price is nuch less than this one. I have used the both,, you can feel slight difference in data transferring speed. But don't go for the "aeoses" product.....totally Chinese product. . .thank you.

1. I have purchased this specifically for pairing Plantronics Legend with my computer. And it has proven to be a better choice than the cheaper CSR 4.0 adapter. 2. I had access to CSR 4.0 adapter when I received the Plantronics handsfree. Therefore, I paired the Plantronics to my computer using the CSR 4.0. Although it allowed communications with the PC, there were some issues - sometimes the voice clarity, both the transmitted and the received, would suffer - i.e. recordings lacked clarity & the incoming voice was not very clear. 3. Today I changed the adapter to this Kinivo. And the difference was noticeable. The transmitted speech was very clear and the received voice is also pristine. 4. To sum it up - if the intention is to use a Bluetooth adapter with handsfree like Plantronics - this is a very good option instead of CSR 4.0. 5. I had a problem regarding driver installation in Windows 7 x64. The solution listed in the following site was able to remedy that -[...]

First off I'll go about the things that are good about it - It uses Broadcom bluetooth drivers, which is a good thing for future updates and wider compatibility, It's small form factor, however I didn't say it's tiny, Good performance, very low latency rate between devices while transmitting data. Now the bad part- It's built quality is cheap, like really cheap, as you could see from the other reviews. You won't believe the knock-off like plastic parts and the way they are being held together. It's like really poor use of glue and will come off without even any big force. So I bought this for my laptop as my inbuilt Qualcomm Bluetooth chipset stopped working with my audio devices, there was noticeable lag and sudden freezes, though file transfer was working fine without any fuss. I use a Sony SRS X3 and Jaybird Freedom for listening music and only for that purpose I needed an external adapter and I bought this. As I said I didn't have any trouble performance wise and I was happy with that. I found about the build quality in the hard way when I went travelling. The adapter was plugged into my laptop and stowed safely in my Everki Concept backpack(which can hold upto 17' laptops, mine is just 15'. So there's plenty of space for protection) and put in the overhead bin. After I reached back home after the trip I took out my laptop and found out that the top half of the plastic part is gone, just broken off from the bottom. I thought maybe this happened due to some turbulence or something. And again I went on to another trip and when I returned and opened up my backpack everything broke bit by bit. I could see all of its parts came off. It was fortunate that all of the parts were still inside the bag, so I picked them up and put them back together without damaging the chip. And I stick them together with Instant Glue that I got for 5 bucks. Voila, it works again even though the top half is still missing. I'd like to say that this was not the only dongle that was connected to the laptop the whole time, I had a Logitech receiver for the F710 Gamepad(3 Years) and another Belkin receiver for the M450 Wireless(2 Years) mouse both of them was plugged in along with the Kinivo Bluetooth adapter(5 Months). I've never taken out both of them during my trips. So, it's definitely the fail of the build quality. Verdict will be that if you're planning to buy this, once you get it do a overall cover before actually using it with some instant glue to protect it. Or at the least do it with some tape and you will be safe. Or good luck taking it of during traveling and searching for it later on.

Today i have got the chance to use it as it was delivered to me in the morning. And one word which comes in my mind after using it is fabulous. I am using windows 10 and the product works like a charm. I was in doubt earlier that whether it would support windows 10 completely or not but now i realise that i haven't done anything wrong in purchasing it. Believe me guys it detects immediately my soundpeats QY7 bluetooth earphone which i also purchased from amazon and i have connected few phones also and it is working fully with each and every bluetooth enabled device. The sound is transmitting fluently from my computer to the earphone and the clarity is as perfect as if i am using a wired headphone. So those who are willing to purchase a bluetooth adapter i would say that it is the best in the market. Go blindly and purchase it. You won't regret. The packaging was also good. Prompt delivery by the seller. Thanks.

When I first setup my custom Windows 8 desktop PC in 2013, I bought an equally expensive ASUS USB BT211 bluetooth adapter http://www.asus.com/in/Networking/USBBT211_Mini_Bluetooth_Dongle/overview/ for the PC. The adapter has been really great. Despite the fact it's Bluetooth v2.1+EDR (it actually registers as a Qualcomm Atheros AR3011 HS v3.0 chip) with max. speed of 3Mbps, it is a power Class 1 device with an amazing range of 100 meters (330 feet) line-of-sight in open space. So, basically, it works uninterrupted in a decently sized bedroom and living room. My "major" application of the device is to wirelessly stream all of the PC audio (movies/songs, etc.) over the bluetooth link to my bluetooth-enabled speakers. Over time, I noticed audio hiccups (not due to range or sync-related concerns) and primarily hang-ups of all media played over bluetooth. Researching the net thoroughly, I learned the ASUS BT211 is "incompatible" with Windows 8/8.1. So, began my search for a latest Win 8/8.1 supported v4.0 Bluetooth LE adapter. After a month of research and convincing, I stumbled upon more than "rave" reviews of the Kinivo BTD-300 and BTD-400 adpaters on Amazon and elsewhere. More importantly, the Kinivos are Microsoft-certified to work with Windows 8. However, when the Kinivo BTD-400 I bought arrived, the story was quite different. Firstly, it's a power Class 2 (not Class 1) device with a max. open space range of 10 meters (33ft). During scan, the Kinivo saw select devices: it saw my Note 2 with v4.0 LE, laptop with v2.1, but not a Logitech Bluetooth audio adapter/receiver with v3.0 http://www.logitech.com/en-in/product/bluetooth-audio-adapter, etc. I spent hours, days trying lots of things/combinations to confirm the problem, before even invoking the Kinivo Customer Care and considering a replacement/return from/to Amazon: - installed the Kinivo BTD-400 on different USB 2.0 and 3.0 ports on my Windows 8.1 desktop PC - set up the BTD-400 with the Broadcom software that came on the CD with the adapter, latest downloaded WIDCOMM software from Broadcom website, and without the software (and just the drivers that windows update automatically installed the adapter as "Broadcom BCM20702 Bluetooth 4.0 USB device). - installed the BTD-400 on several USB ports on two other PC and laptop computers. - uninstalled, rebooted, and reinstalled the BTD-400 in all of the above cases. - brought the BTD-400 less than an inch away from the Logitech BT Adapter. - disabled all Wi-Fi devices, antenna/router transmissions, keyboard/mouse wireless receivers, cell phones during the bluetooth scan to eliminate interference. -played around with the "Services" settings for Bluetooth devices, etc.... After thoroughly doing all of the above, I contacted Kinivo Customer Support via email (Case Number 89680) conveying that the BTD-400 is simply "blind" and unable to find the Logitech BT Adapter when the ASUS BT211 and all my other PC and laptop bluetooth adapters are able to connect, pair, and stream audio/media to the Logitech BT. Even a cheap Rs. 150/- Enter bluetooth adapter (http://www.amazon.in/Enter-2-0-Wireless-USB-Bluetooth/dp/B00JRU6ASU/ref=sr_1_2?ie=UTF8&qid=1432405456&sr=8-2&keywords=usb+bluetooth) connected to the Logitech BT adapter. The Kinivo Customer care replies were so incessantly "adamant," "unyielding, and "unwilling" to accept that the BTD-400 is questionably faulty and perhaps has some RF issues that it doesn't detect the particular frequency band or the A2DP protocol the Logitech BT v3.0 is communicating over. I conveyed to them that I am sorta geek tech by profession and possess a Master's in Wireless Engineering from a reputed US university. Yet, the fortnight-long email exchange kept circling with lame things to try like "Change settings of the Bluetooth Services," "Make sure to put the Logitech BT in pairing mode and that it's not connected to other devices" (BTW, the Logitech BT has a multi-point technology allowing it pair with multiple bluetooth devices at a time), "Contact Logitech for support, your audio adapter has problems," etc. Every response was from a "new" agent who never cared to read the history below in the email thread and kept repeating ideas that previous customer reps already had suggested in a reply days ago to try. It's like they have a "BIG EGO" that they don't want to accept the difficult time a customer (who may not always be a techie) is having and instead of recommending a replacement/return, they just kept going on and on in circles. I was being nice to hold my ground to get a resolution, so that I don't have to return/replace. But, when I saw a pattern repeat, I ultimately gave up and returned the device to Amazon. Bet, even large companies like Apple and Google may not be as reluctant and egoistic. Shame! I finally ended up buying an amazing and smoothly functioning CSR 4.0 (with CSR8510 A10 chipset) bluetooth dongle from ebay for Rs. 290/- http://www.ebay.com/itm/171578086759. In fact the CSR 4.0 I received has a minor range issue, so when I wrote back to the seller and explained the problem well, he was happy to refund my money or send me a replacement all the way from China, without having me return the 1st piece. I request the Kinivo Support to please not to reply to this review as I have resiliently gone beyond an average customer capacity to look into every nook and cranny of the particular BTD-400 device I received, concluding that it indeed had a problem. Rather, please review the Case Number & the Serial of the device I sent back to diagnose the problem.

Re: Automatic connection with device might not take place (in case of Kinivo BTH240 Bluetooth Stereo Headphone). You need to switch Bluetooth on in settings (in case of Windows 10) and then pair the device again by first removing the paired device. It would have been better if the usb were bigger since it becomes difficult to grip the usb when taking it out. This is an amazing product if your laptop doesn't have bluetooth hardware. I had no difficulty installing the adapter. For alternate installation the following link has detailed step by step instructions for installing the adapter especially if you have windows 10 in your laptop. https://support.kinivo.com/customer/portal/topics/836962?t=536917 (Click on Windows 10 installation for detailed instructions) After inserting the adapter into a USB slot, a window should pop up that will install the required software(for windows 10). This will only happen if all bluetooth software has been uninstalled (refer to above link for further details). To add a bluetooth device click on the bluetooth icon on the right hand side of the taskbar, and click on add a device. After the device has been detected and paired, a window should open from which you can disconnect and connect to your bluetooth device.

Initially, i was about to return the product as it was unable to connect to my Bluetooth speakers - it only pairs but does not connect. Spent 2-3 hours on google regarding problem but no use. Then I uninstalled all the Bluetooth drivers from the system (windows 7, 64 bit). Did multiple restarts. Cleaned the temp files. then plugged this adapter and installed drivers downloaded from kinivo website. After all this finally, this product works and now it is working like a charm. It connects to my Bluetooth speakers as soon as windows login screen comes. Completely hassle free now. one star less due to initial problems faced in connection and music quality over this adapter is not superb but very good.

Te duur voor wat het maar is. Kocht daarna een bluetooth dongle van €15 en die werkt even goed, ook onder linux.

Nach 4 Versuchen (Hama, CSL, ...) nun endlich ein Dongle, der Folgendes auf Anhieb macht: - einstecken in Windows 8.1 PC und selbstständige Installation (Bluetooth Icon erscheint in der Taskleiste) - Koppeln mit Dualshock 4 Controller klappt problemlos (PS Button und Share-Button gedrückt halten, bis Controller weiß blinkt) - das DS4Tool 1.2.2 erkennt den Controller sofort. yay. Endlich gediegen vom Sofa über PC und Beamer daddeln!

I just got this and the literature with it does not mention Windows 8. Probably because it was produced before that was released or their software was compatible. First, the instructions will tell you to delete the Bluetooth software installed on the computer, I did not do this and had no trouble, just my experience. Also the software on the CD did NOT work with Windows 8, so go to the website [...] where you can download software that works with Win8 OS. The title says update but it also of course downloads the latest drivers you will need for this. My new HP laptop said that it worked with Bluetooth devices so I had attempted to use it before discovering that just meant that it was capable of doing so when an adapter such as this was installed. It takes up one of your USB ports so you can remove it when not using it and don't have to do anything but plug it back in. If you do have room to leave it plugged in then if you have both USB 2.0 and 3.0 devices I would use the 2.0 port to leave open the 3.0 for other things unless your Bluetooth device dictates otherwise. The adapter is small and sticks out less than a 1/2 inch from the USB port I have it plugged in to. I have it located to a USB port near my power cord on my laptop which makes it even less of an issue as the power cord sticks out much further and also sort of provides a little protection for this device when both are plugged in. In any case I don't see any issues with it getting damaged when used on a laptop by any physical issues. There is a tiny flashing blue light but is so small and not at the end of the device but close to the USB port it is plugged in to that I don't notice it and it does not bother me, even in the dark. So far I have just connected two of the Bluetooth headsets that I use with my cell phones. A Blue Ant Q2 and a Plantronics Voyager Pro+. Both of those have connected and worked great. One thing that I have noticed is that when I attempted to use a second Q2 I have it would not connect. I do not know why. I reset it to have no other devices paired in memory and still no go. When I find my 3rd one of these I will try it but that is the only issue I have had and not yet resolved. This adapter is small and does not come with any adware or bloatware to worry about, no trying to change your homepage during installation of the driver or any of that to worry about etc.. It is worth the money and is good that it is Bluetooth 4.0 while also being backwards compatible as I have already tired. There are less expensive versions that are 3.0 or less but intentionally buying an obsolete product to save a couple bucks in the fast changing computer world is not worth it in my opinion. This works and for $15 bucks I have no complaints.

When I installed BT programs including pulse-audio Mint installed it easily. Windows 10 may have driver issues. See kinivo site and Microsoft for instructions. But it is detected and lights up. I don't have speakers but trying to pair with Phonek Marvel hearing aids instead.

Su PC, ho connesso mouse e tastiera bluetooth in un baleno. Purtroppo, a me serve sul nas, un Qnap tvs-673: ebbene, funziona con l'audio, ma non con mouse e tastiera. Questo perché Qnap non supporta l'emulazione HID bluetooth via software. Pertanto, il prodotto è validissimo se collegato a un dispositivo con supporto al bluetooth via HID. Ottimo come sempre il servizio Amazon.
