Qfx Folding Bluetooth Stereo Headphones

[1x CR2032] Very easy to integrate into my stereo/home theater system, and could not be simpler to use with my bluetooth headphones.

[1.0 lb / 0.5 kg] I use them for my ATH-M50Xs and am able to store them without folding the headphones up

[30 Hours (BT)] I use the headphones to listen to TV late at night via bluetooth. Between the Headphones & TV they connect automatically with easy volume controls.

[>-86 dB] This receiver has revitalized my 1980s stereo system by allowing Bluetooth transfer from my Sony Walkman (CD quality) and from an iPhone. When powered the receiver goes into pairing mode--your device remembers this receiver...you are connected. So far there has been no problem with connection or distance from the receiver. As this is my second unit (first attached to another stereo system) I only wish I could rename the unit as it comes up with the same name...only to be identified by the Bluetooth address. If you only have one of these, this will not be an issue. Attachment is simple: connect using RCA supplied cord to your receiver aux input. Having it on a switched plug on the receiver is very convenient. If not, you would have to push the light button to switch it into on mode. It has an auto off after a few minutes of not receiving a signal. It also has an optical connection.

[Closed-Back] is wonderful for bluetooth transmission of iphone over home stereo system....remote controling of audio content to stereo

[0.085 lb] I'd just bought a soundcard and I was going to use this cable as an output cable to my mini-soundcard , eventhough its wasn't successful I'd still used it for my stereo Bluetooth speakers

[40 W at 4 Ohms] Also more than expected. I bought this to drive outdoor speakers and figured I'd spend a few more dollars to get Bluetooth. Well B&H must be showing a slightly older model because what I received also has an SD card slot in addition to the USB port and it will play mp3 files! It also has an FM tuner built in. I expected to feed this amp from my main stereo just to drive the outdoor speakers but since the Pyle also has line level output jacks I can also feed my stereo from the Pyle. I was a little afraid of a feedback loop while fiddling with switches but it has not happened. So now I can play mp3's or a Bluetooth source through the whole house inside & out. Perfect! The Pyle also seems to have tons of power. I easily drive a pair of Polk outdoor speakers with the Pyle volume just above zero. If there is any high volume distortion I'll never hear it unless I blow out the speakers. I could very easily drive a second pair of speakers with the Pyle. Great device, very compact, not much heat, good controls. Nothing to dislike. Hope it has a long life.

[±3%] This device turns any 3.5mm stereo into a Bluetooth source. Pairing this device with my Pixel Buds was painless. I bought two on these, one paired to my Buds, one paired to my wife's Buds.

[Glass] enables me to send my Apple Music from my phone to my older stereo receiver which is pre Bluetooth.

[1.9 kHz ] Bought these to have better stereo sound than my very small portable Ultimate Ears bluetooth speaker, which I primarily use while traveling but lately also around the house. Set these up in my living room and really enjoy the sound they put out. Very musical and enjoyable, even while streaming non-Audiophile quality Spotify Free. Two thumbs up for great sound quality and connectivity at an affordable price. Just plug them into a wall outlet and you're off!
