At a retail price of just $49.50, the Brainwavz S0 are a great, cost-effective option that delivers above expectation. They have a very smooth and easy going sound signature, are comfortable to wear, and come with a ton of additional ear tips. I definitely recommend checking them out.

Brainwavz S0 In-Ear Monitors Detailed Review


​Brainwavz have decided to go with a very sleek and clean look this time around. The earpieces themselves have a similar shape as that of the S5, but the S0's are smaller and don't have the angled nozzle. Unlike the S5, the S0 are designed to wear down, not over the ear. There has been some debate whether or not this was the right move. It's a matter of personal preference, but I think it was. I enjoy wearing my IEMs downwards and had no problems with them trying to sneak out of my ears at all.

The housings of the earpieces are made out of metal and painted black. Needless to say, this makes them feel very solid and durable. Moving to the cable, we meet a strain relief made from hard, red rubber. This is one of the most vulnerable spots on the cable so the solid protection makes perfect sense.

I've heard some people say they're unhappy with the flat cable. Personally I had no issues with it whatsoever. It collects in a simple, solid Y-split which does it's job nicely. A repeating aspect of the Brainwavz S0 is that it is smaller than its predecessor, the S5, and the Y-split is no exception.

Brainwavz S0 Packaging

It was a pleasant surprise to open the parcel Brainwavz sent me. I was greeted by a beautiful packaging that I couldn't wait to rip open. I managed to resist the urge just long enough to snap the picture on the right hand side. Included in the package was: 

  • Brainwavz S0 Headphones
  • Hard Carrying Case
  • Shirt Clip
  • 1 Set Foam Ear Tips (Comply S400)
  • 6 Sets of Silicone Tips
  • 1 Set of Bi-Flange Silicone Tips
  • 1 Set of Tri-Flange Silicone Tips

The carrying case is fantastic, by the way! It may be a bit large, but it offers great protection and has two very convenient pockets on the two sides. It's just overall a very high quality case. Brainwavz could easily have charged $20 for it alone, which to me makes the retail price of $49.50 a steal. 

As is evident from the list above, the Brainwavz S0 comes with a large variety of ear tips. This is something I absolutely love, as it lets you sculpt the headphones to your ears. The bi-flange ear tips ended up being my preferred tips of choice.

How Do They Compare?

Let's look at some of Brainwavz S0's competition:

JVC XX Earbuds

JVC HAFX1X Xtreme Xplosives - The S0 is, hands down, a better pair of IEMs. They have a clearer sound and less of a bass emphasis. The price is the only aspect where the JVC takes the lead (although, the difference in price isn't very large). They are a decent pair of headphones considering their low cost, but setting them up against the Brainwavz S0 - the S0 comes out on top every time.

Brainwavz S5

Brainwavz S5 - The S5 has a higher level of detail and a better overall sound quality. However, the S0 is smoother than the S5 and the bass is more in balance with the mids. They do have a bit less clarity though, but at half the price I wouldn't expect anything else. Choosing between the S0 and S5 basically comes down to preference. They're both great IEMs, with slightly different sound signatures. The S5 is aggressive and clear, while the S0 is warm and smooth.

Tekfusion Twinwoofers

Tekfusion Twinwoofers - The two of them are in the same price class. The Twinwoofers are a very bassy pair of headphones, while the bass of the Brainwavz S0 is more balanced. The sound of the S0 is quite refined, while the Twinwoofers' is more colored. As you can see, these two IEMs do have quite different sound signatures.

Since the two of them sit at the same price range, this too comes down to preference. I'd recommend the Twinwoofer for the basshead, and the S0 for basically anyone else. The S0 just has a much better overall sound.

Should I Buy the Brainwavz S0?

If you're looking for a relatively cheap pair of IEMs that are of good quality, then the Brainwavz S0 might be exactly what you're looking for. They have a very smooth and easy going sound signature, are comfortable, and are just overall a pair of quality headphones.

There are two scenarios where I don't recommend you purchase the S0. They are:

  • You're a basshead and want as much bass as possible.
  • You're willing to spend considerably more than $50. In this case a high end pair of IEMs might be a better choice.

If the scenarios above don't apply to you, then I absolutely recommend you check them out. They're easily one of the best IEMs that I have used in a very long time, and with a retail price of $50 they're a steal!
