Intro

Contents

We know the Swedish no-nonsense brand Supra mainly for their cables. Those very recognizable blue ‘snakes’. When the Swedes came out with over-ear headphones, your author must confess that he was a bit puzzled…. why would they do that? However: the northerners did accumulate enough credits to give it a serious look. Time for the Supra – Sound by Sweden – Nitro X over ear!

We must confess that we do have a soft spot for the brand with the blue cables. The Swedes are very down-to-earth in their approach and it shows in the products and prices. Solid performance for decent prices. For that reason, we regularly recommend them to readers who do not want to spend extreme amounts on cabling.

Supra Nitro X

The wireless over-ear – The Sound by Sweden Nitro X – is a bluetooth headphone with noise cancellation and, of course, the option of using a cable. Which comes in handy when the battery runs out after about 35 hours of playing music. That’s enough to get you through some serious car rides and enjoy some more music on vacation. Your author speaks from experience, because last vacation his son enjoyed an entire vacation with these headphones without having to charge them once. No complaints about comfort or playback quality either, by the way…. and that’s saying something, because this 11-year-old youngster’s ears are already becoming quite critical!

If we briefly go through some specifications, we see Bluetooth 5.0 (including support for AAC), a real Supra audio cable (3.5mm, 7N copper), 4 microphones for calling and noise cancellation, a 40mm driver that can reproduce 20 Hz – 20 kHz, 32 Ohm impedance (which is fine to drive with a smartphone) and USB-C for charging. No USB dac, unfortunately.

The only thing missing – or we haven’t looked hard – is an app. We can’t find a companion app for additional settings. Think noise cancellation profiles or an equalizer. By now that’s pretty standard with wireless headphones.

Comfort!

One of the things that immediately stands out is comfort. This over-ear is really an comfort wonder! The cushions are soft, don’t overheat the ears and also seal well with just the right amount of pressure on the head. An excellent combination that we don’t always find in this price range. So Supra manages to do just that. Hats off to them.

No noise

Then a point that many users value – your author does not, by the way: noise cancellation. It is excellent. The cushions already block a lot (which is why NC is not so important to your author), but with noise cancellation there is real silence. Even dynamic sounds are filtered out perfectly. And not all systems can do that.

Now it is true that the reproduction suffers a little from noise cancellation. Of course this is not very strange, but it is important to mention it. The treble is a bit tamer and the ambiance – or air in the music – is rounded off a bit more. Not dramatically, but still audible.

In the carrying case

The foldable headphones come with a handy storage case, a usb cable for charging, an adapter plug for the plane and, of course, the 3.5mm audio cable.
