RevengeOfThePiff –
Surprisingly solid, and endlessly useful product, for Pro Audio, and Audiophiles/Hi-Fi enthusiasts.
As someone who has done professional audio, DJ’ing, and never was sold on other variants of these. These little adaptors, are the best I’ve had, even having spent more in the past on ones that didn’t cut it.Pros:- Excellent Durability- Obvious attention to quality control, which, normally isn’t something that most would think of with something this small, especially at the great price point.- Everything is gold plated, and testing with a voltmeter, there’s almost no variance; it’s not your average copper, so don’t let that fool you when you read their title. That is no standard cheap copper, like a lot of old speaker wire is. This is all gold plated, and it’s got the best connection for a little adapter, out of the many many I have used in the past. They’re excellent, and you lose absolutely zero quality, which I cannot say the same about for the bin that I’ve got years worth of other ones in, which don’t have near this quality.- You cannot beat this price. You can’t, not without sacrificing the quality of whatever you need to convert to 3.5mm/normal headphone jack on most devices. I keep these with me whenever I want to go out, and listen to high quality headphones, on my phone, or music player. I just hope they don’t see this review, and the price goes up haha.Cons:There’s not a thing about these I have found that I don’t like. They’re balanced, they’re extremely well made, and you can tell the manufacturer, was putting quality control/build quality, as a major priority, which, you don’t see often from small adaptors, especially this specific kind.They are built like a tank, so, again no “Cons” to be seen. If you need balanced adaptors, and don’t want to go through a litany of them, for years, before you find ones that hold up like nobody’s business, these are the ones you need, and for the price; STOP READING AND GET THEM ALREADY haha.I’m so happy with these, that I wish I was just able to deal with this company directly, as, it’s pretty rare (sorry for the redundancy), to find quality this good let alone at this price.This is what good attention to detail, knowing your market, and, it’s like someone who has their own passion for music and audio quality, was in charge before they let this go out into the world. Get them, you really can’t go wrong.

1/4â audio Jack to 1/8â audio (computer) conversion Jack works well enough and looks good
Wanted to listen to music from my laptop through a decent set of cans, Sennheiser HD 280 Pros. When Iâm rich and famous Iâll upgrade to amazon Musics Premium HD subscription, but Prime works well enough for me right now (barely). The cans come with a standard 1/4â RCA Jack, my laptop has a minuscule 1/8â audio output Jack. Looked on amazon to see what was available to bridge the size gap, and these ANDTOBO jacks popped up. My Sennheiser canâs jacks are gold trimmed, these ANDTOBO jacks are gold trimmed (colored gold, surely not actually trimmed in gold). So not only did the ANTOBOs fit, they looked good doing it. Sold. Iâm sure you can find cheaper conversion jacks elsewhere online. Maybe even better quality jacks for less money. These work well enough for me.
Critic –
Poor sound quality
It technically works but the connection is pretty bad and needs constant fiddling to keep sound coming through. A lot of static too.
