"Paired it with adapter made for these headphones."
"The Mpow in the picture has the (included) double male adapter inserted. If you pair your Mpow as a receiver, a long push on the '+' button will trigger the shutter on your iPhone ProCamera. That is, if you have the ProCamera App from the app store, which I highly recommend as it basically turns the iPhone 7 plus into a professional camera (RAW images, better HDR, low light options, manual control of focus, shutter and aperture, on screen histograms) I'm thinking this will come in very handy."

"I bought this for my wife's Mazda after the factory Bluetooth module went bad for the fourth time since we've owned the car. The first three times it was replaced under warranty but the fourth failure occurred after the warranty elapsed and Mazda wanted to charge me $600 for the module part alone. There was no way I was paying $600 for a part that had already failed us four previous times, so I started searching for alternatives."
"I also wanted to place it on the drivers left hand side by the window because the microphone for phone calls picks up better over there but the cord is too short so I have to add an auxiliary and USB extension."
"Edit: Three months later still as good as Knivio BTC450."
"When IPhone got rid of the headphone jack it meant my wife had to choose between playing music in her van and charging her phone."
"It may be a bit bulky with the noise reducing adapter connected, but nothing that can't be ignored or moved out of the way."
"works great."
"No static and my husband and my phones automatically connect, unlike others I tried."
"Update Jan 19, 2018: After a month, the device overheated and no longer functions. The device beeps when connect, beeps when the volume is maxed, beeps for notifications, and, the worst part, beeps every time a song is skipped."

"I have a great Bluetooth headphones (Satechi Aluminum Bluetooth Wireless Headphones) that I wanted to use at my work computer so I would not distract my other co-workers. The Plugable Technologies allows any non Bluetooth accessible computer or laptop to have Bluetooth capabilities to use with Bluetooth headphones, mice, speakers, keyboards, etc."
"To test it out, I took out my PS4 Bluetooth controller, held down the pairing buttons(briefing holding down the Playstation button while the Share button was held down), and in about 30 seconds total, Windows 10 had finished the process of pairing and connecting my controller via Bluetooth - simple, quick, and magnificent."
"After the initial pairing, connecting it after turning it off is quite quick, and it works with DS4 windows so you can change aspects like the controller light bar color, remap buttons (for emulating a xbox 360 controller in some pc games), or turn off rumble."
"After several hours spent installing, uninstalling drivers, chatting with Microsoft (zero help there...cookie cutter answers that said nothing + made me diagnostic tool that also found nothing) I was dead in the water with wireless bluetooth headphones that worked before the MS update and now only worked with a wire."
"I really like the products from Plugable."
"This works fairly well with my wireless headphones."
"Bought this for my work computer to connect my blue tooth head phones (Skull Candy Grind wireless: LOVE!)."

"And like many other people my age, the crates of vinyl got stored and rarely played. Well, recently while going through some old keepsake items, I kept looking at those old crates of records and caught a new vinyl bug. I did pick up an extra stylus head and opted for an Audio Technica AT440MLB cart and now this thing really sounds good. It comes with Audacity software to load onto your computer so you can just plug the unit into your computer and archive all your vinyl to MP3, etc. But it is a known fact on these Turntables, this built in Pre amp, even when not in use tends to darken or muddy up the overall sound or your records. I plan on keeping mine stock just in case I ever want to archive all my vinyl one day..and have worked around the whole "Muddy, Dark" sound issue with the use of the AT440MLB cart and a little ol thing called an EQ. A little EQ adjustment for Vinyl...store the setting in one of the six pre sets on the Technics EQ and all done. But if you just want to play your records with a quality unit that will sound great, not tear up your records and looks fantastic I highly recommend this unit."
"I have been listening to my vinyl more and more lately and, while there wasn't anything wrong with my old turntable, I just kept thinking/feeling that I wasn't getting the best sound from it so I started looking around for an upgrade. I'm not one of those guys who sits around in a smoking jacket sipping brandy... analyzing the sound quality of my music. It is heavy (there is a large metal weight bolted inside the bottom of the chassis (I found this out by watching a couple youtube videos). There are a lot of features here that I'll probably never use... not a DJ so I don't know that I really need to change the pitch of my music or play a record backwards. I fully expected the cover to cost a crazy amount of money and for it to be such a huge pain in the ass that I'd just say the heck with it."

"(one of the stores was an electronics store). I realize that I am older but I am not that old (79) and still appreciate listening to my reasonably extensive CD collection and I still purchase CD's, and I apparently wrongly assumed clerks still knew about components."
"I also use the 'programable' feature to program certain songs on specific CDs (i.e create a playlist of any of the songs on the CDs you put in) - it's always worked for me."
"I have mine attached to the surround speaker system for home theater. It sounds great and I can get hours of music, Very pleased customer here.Onkyo DXC390 6 Disc CD Changer."
"Bought this for my mother to replace a similar Sony 5 cd unit that finally died after 20+ years."
"But I found that I had several disc that had sections where I would loose the sound from one speaker, or cracking/popping sound, always at the same place."
"It works smoothly, easy to set up and use and the sound quality is great."
"3 months in and the machines brain is not working."
"When I played the same discs in another CD player, they worked fine, so the problem was this Onkyo DXC390 player and not my disc."
