TP-Link NFC-Enabled Bluetooth 4.1 Receiver, Wireless Audio Adapter Streaming Music from Echo Smart Phone Tablet PC to Home Car Stereo Sound System (HA100)

It works great. I bought mine in 2019. No on and off switch, but so what? Other reviewers say it's easy to unplug it, but in fact mine has been plugged in for over 5 years full time. I do believe this is no issue since it clearly is not doing any digital to analog converting until you connect to it with your phone and play your music. If it costs a nickel per year to leave it on powering its little LED light I'd be surprised. So for me it's always ready. In all these years there was one occasion when I couldn't connect to it, and I just unplugged it and plugged it back in, and it hasn't failed for years since. I pay for commercial free YouTube premium, and whatever music I can think of to play from my phone to my old stereo system is always there. It comes with a 3.5 to dual RCA jacks cable for your auxiliary or tape input on your receiver, and that's all I need.The problem I now have is that I want another one as a gift to a friend. But whereas I paid about $22 plus tax, they are now asking about 60 bucks and more all these years later! It's Bluetooth 4.1 and has noticeable lip sync latency if you watch a phone video or connect your television to it. But I don't need to do that. It's making me crazy to think of paying nearly triple, but if you don't mind the price it is likely very much the smallest lightest unit of its kind out there. I'm not sure why that makes much matter however, it certainly doesn't justify the new price in my book!

I'm sure most people purchasing this are looking to add this to their A/V receiver. I'll get this out of the way and say that it works perfectly for that situation, it's pretty much plug and play with a little bit of a setup on your phone, or whatever Bluetooth device you're trying to pair with it, such as the Echo or Echo Dot. I bought it for a different reason. If you're like me, you bought an Echo Dot during Prime Day, because why not? The price was attractive. Now, I like the dot, but what I don't like is it's sound quality. I have Amazon Music, and the tinny sound of it's internal speakers just doesn't quite do it for me. Luckily I have an expensive, loud af, 7.1 Sound System to remedy that issue. Through some cable frakensteining, I have my PC's sound route from my PC through my TV, which functions not only as a TV, but a second monitor, which then routes to my A/V receiver.Wouldn't it be great if the Echo Dot would play through my speakers WITHOUT me having to dedicate a single channel to it? In otherwords, while I still hear all my sound on my PC or TV, such as games or movies, wouldn't it be great having the Echo Dot be able to listen to me and say things on the same input? It would. But Amazon still hasn't caught up to the idea that some of us consider our PC's to be outputs, not only input. I'm going to explain how to do this, because for whatever reason Amazon's software refuses to recognize PC's as speakers, only the dot as a speaker. This is why you need this device. Here's the process, it's simple:By default, setting up Bluetooth on the Echo Dot causes the pair to use the dot as the primary speaker. Buy this device to remedy that issue. I'm also assuming you've already paired your echo with the tp link via the alexa mobile app on your smartphone. If not, do this first.Step 1: Plug in the TP-Link Receiver NOT to your A/V receiver but to the mic input of your PC.Step 2: Go into Windows sound settings (The control panel screen)Step 3: Go to Recording Devices Tab.Step 4: Go to Properties of the Recording device you connected your audio cable from the TP Link to the mic jack by right clicking on it. Probably Realtek, unless you have a sound card like I do. In this example, I connected it to my Sound Blaster card, so I'd go to the properties of the respective mic. For a regular PC without a soundcard, it'd likely be your Realtek mic jack on the back of your pc.Step 5: In properties, go to the Listen Tab. Make sure your correct sound device is selected.Step 6: Check the "Listen to this Device" checkbox.DONE! That's it. That's all you need to do to have the Echo Dot work simultaneously in the background while you watch youtube, or play games on your PC, all on the same channel input. Pretty neat huh?I've attached a visual aid to this.NOTE: You sometimes DO need to ask Alexa to either disconnect from the tp link, or reconnect to it depending on whether your motherboard turns on or off during a full shutdown. In my case, before bed or if I turn my PC off (since my motherboard also shuts down) I say "Alex, disconnect from TP Link" and she'll start playing sound from my Echo Dot instead. Then if I turn my PC back on, I say "Alexa, connect to TP Link" and voila, back in business.Hope this helps, I had a bit of an annoying journey trying to get this to work, so my pain will hopefully translate to your ease of mind. Hope you guys found this helpful!As for the device itself? So far so good. Audio quality isn't perfect, but that's a bluetooth limitation, not a device limitation.Protip: Adjust the mic volume levels to coutner any distortion you hear, also turn off ANY and ALL mic effects you might have on, or alexa will sounds like she's downing underwater. Don't torture Alexa.

I have purchased and used TP-Link products in the past, but until we purchased this HA100 Bluetooth Receiver on the annual Prime Day sale, I've been underwhelmed by their lack of customer support. I searched for this on the TP-Link site but TPLink's site was down, and doesn't even generate a 404 error message, par for the case, that some days provider sites don't even work at all. That said, Network Giant was the vender on this sale, fulfilled by Amazon. This small, round receiver does what the marketing information claims and the white power-on indicator light is a nice change from all the eye-popping blue and red LED lights on such units. I wanted to transmit music from my tablets and phones to this unit to my discrete stereo, or through my headphone/amp, as can be done with the Echo devices. The music was surprisingly clean, but a a bit dull, or rather seemed to lack brilliance in the top third of the EQ bands, which was easily adjusted to taste with the stereo's controls. This unit is bluetooth 4.1, and I'd like to see it produced in Bluetooth 4.2, at least if TP-Link ever gets around to updating it; if so, I'd buy it. I've linked it to the Echo-Dot as an experiment and it seems to perform well enough, but Echo/Dot is in a different review, and isn't why I purchased this unit. It doesn't have any trouble linking with and playing music from Windows-NFC/Apple and/or Android units, as long as it's in line of site. The HA100 pairs automatically and quickly, without any code entry required. I was surprised that I was able to transmits to it in the bedroom (about 20 through a very thin panelled wall) and out to about 45 feet at the rear of the home, which is all I needed for it to do. I didn't notice any appreciable delay unless using it with older android units. The HA100's under $20 pricetag gives you a 2-year warranty on the receiver-good luck if you ever have to contact TP-Link with a warrany concern, but personally, I'd rather swim through burning coals). The connecting cords aren't the best, but can get the job done. A small manual is included that contains miniscule printing; Perhaps the manufacturers don't realize if they made these inserts readable, it would be appreciated by most purchasers. I always try to read the fine manual, if I can see it without a magnifying glass, and would love to commend someone for making them large enough to actually read. In fact the only real gripe I have is that the connecting cords could easily be mage sturdier and longer so that the user could route/hide the cords more effectively in a home multi-unit stereo environment, so the unit could be placed in an optimum position for reception. The HA100 pairs easily with all of our units, and doesn't present much (noticable) lag unless you try to use it through other than very thin walls, or between floors; clearly this a problem for bluetooth in general. As others have noted, it's quite easy to plug these types of receivers into a lithiim ion battery-bank to provide a source of off-grid power. In all, this seems to be a well made unit that meets our price/performance expectations, and gets a solid 5 Star rating. This opinion is mine; no entity exerted any influence to sway the review. I hope this helps other Amazonians to make good purchasing decisions.
