You’re listening to a song and you really want to share it with your friend. You can pull out one of your earbuds but audio quality takes a dive and that’s just plain unsanitary. Even if your friend has a set of headphones, it’s unlikely you’ll have a splitter cable with you. Onanoff has remedied this issue with its Magnum in-ear headphones; the splitter is built into the jack. How well does this actually work? Hit the jump for our full review of the Magnum headphones and Magneat cable manager!

The Onanoff Magnum come in a relatively small cardboard box with a window on the front and a cardboard flap on the back detailing the product. Inside, you get the headphones, a Magneat (more on that later), and extra silicone tips. The packaging and accessories aren’t amazing but they get the job done. 

The Onanoff Magnum are pretty well built. The earbuds are enclosed in a sort of metal frame with plastic inside. The actual material is ABS/aluminum alloy. Although I wouldn’t describe the headphones as heavy, they do feel pretty substantial. The braided cloth cable is durable, lightweight, tangle free. It’s just the right length too.  

While the Magnums aren’t the best looking pair of headphones we’ve seen, they definitely have a nice distinctive look. Thanks to the the semi metallic enclosure, the headphones don’t look cheap at all. It appears as if the actual earbuds are quite small (the plastic cylinder inside) and the metal frame is only there for extra support. 

The Magnum headphones come with three sizes of silicone tips. While we would have preferred foam tips like Comply, the silicone tips weren’t too uncomfortable and blocked out a decent amount of sound. 

There are two main features to the Magnum headphones - the Lovejack and the Magneat. The Lovejack is basically a headphone splitter built right into the 3.5 mm jack on the headphones. You don’t have to worry about the double wide headphone jack not fitting in your designs though - the second jack is slightly elevated so you’re allotted a couple millimeters of regular jack space. We found the concept to be pretty neat and in practice, the built in splitter wasn’t too shabby at all. The second pair of headphones doesn’t have to be another Magnum although you can chain up to four headphones if they are also Magnums.

Aside from the headphone splitter, the Magneat is probably the highlight of the show. It’s a two part magnetic cable winder. You take one part and put it inside your shirt, allowing the magnet on the outside to clamp down and hold it in place. Then you wind your cable around the Magneat and slide it into the indentation at the top. In theory, it works although we can’t imagine wearing a magnet around on our shirts all day. However, Onanoff has clearly thought of this issue - the Magneat comes in a plethora of different styles and are available separately for $12.99-14.99

The single button remote and mic works well and provides a nice tactile feedback. The module is quite tiny on the cable but we’re not convinced it’s of very good build quality at all, being thin and plasticky. 

 

When it comes to sound quality, the Magnums aren’t too shabby at all. Highs are very pronounced but mids and lows resonate well. are not great but they don’t sound horrible either. Noise isolation is pretty good with the stock silicone earbuds. Bass is nice and punchy while vocals are pretty clear. On occasion, however, the sound can get rather fuzzy. 

At a price of $49.99, we’re not convinced the Magnums are the best headphones you can get for your money. What we can tell you for a fact is that these headphones sound good, are relatively durable, and have a couple of really nifty features. If the situation we described in the intro is one you constantly find yourself in, the Magnum’s cable splitter will probably make the decision to purchase for you.
