Sudio earphones – A review of the Tolv, Nivå, Tre and Vasa Blå

Sudio Tolv Niva Case Open

One of the things I like to bring along on my travels is a good pair of earphones – besides using them to listen to music on long transits, I often use my earphones as earplugs to shut out travel noise, whether it’s screaming toddlers on the plane or excessively chatty seat neighbours. In recent years I’ve been using earphones by Sudio Sweden, and I’ve road-tested the headphone jack-free Sudio Vasa Blå and Sudio Tre on my travels, as well as their truly wireless Sudio Nivå and Sudio Tolv, and thought I’d share with you my review of these Sudio earphones.

Also awesome? I have a 15% Sudio discount code if you are interested in buying Sudio earphones for yourself – scroll down to the bottom of the post because you know you have to work for it. Note that the earphones were all sponsored by Sudio, but this review is all my personal, layman, non-audio expert opinion.

What I’m looking for in earphones


I prefer earphones to headphones mostly because I want something light and portable that’s easy to throw into a bag and carry around. I also like earphones because they are more discreet (I can hide them under my hair) and they don’t flatten your hair like headphones do. 


I’m honestly not super fussed about actual sound quality technicalities, but more so whether they are comfortable, don’t keep falling out of my ear and how well they block out sound around me – I put my earphones on to escape into my own space, so I want earphones that are good at keeping sound out but are still comfortable to wear.

I’ve taken to wearing earphones on noisy planes and trains to block out the background engine roars – you don’t realise how loud and grating the sounds are until you block them out. I prefer them to earplugs because you have the option of playing music with earphones.

My earphone requirements are probably not the most conventional, but I just wanted to give some context as to how I’m reviewing these earphones. Before this, I mostly used the Apple headphones that came with the iPhone just because they were there and I didn’t have to go out and try and pick a pair, the sheer selection available in the market is a bit overwhelming for me.

Truly wireless earphones

Sudio Nivå

I first got to test the Sudio Nivå in 2018. Sudio calls the Nivå their ‘truly wireless’ earphones, and sure enough, these are practically two fancy earbuds without any wires in sight, quite a far cry from the Vasa Blå and the Tre which I will talk a bit more about below.

Sudio Niva Buds and Case
The Sudio earphones come in a sleek round carrying case that is also a charging case

These earphones look a bit bulky but sit surprisingly comfortably in my ear – you twist them so they sit sort of horizontally, and they really seal out sound from entering your ear. Connecting them via Bluetooth is quite simple – just hold down the button on the earbud. Despite there not being a 3-button control panel like the other earphones, you can still control the play/pause and switch to taking calls all from the one button on the right earphone.

When you’re done, you pop the earphones back into the case, and the case automatically switches the earphones off for you, and provides up to 3-4 charges on the go so that 3.5 hours of playtime is extended to almost 17 hours, more than double the other two earphones which hold 8-9 hours at a go.

Just showing you what it looks like inside and where you pop the earbuds back in. The charging point is on the outside back of the case.

What would really be cool is if you could actually use the case as a portable battery to charge other devices – that would make it super useful, but for now it can only charge the Nivå earphones. There isn’t any other way to charge the earphones though, so you are stuck toting around the case which makes it less compact for longer trips.

I like how well they block out sound, and while I’m no expert, even I can tell you that the sound from the Nivå is pretty bassy compared to the other two earphones, great if you like that sorta sound and makes watching dramatic movies even more adrenaline-pumping. I had them in for a few hours watching movies on my laptop, and they were pretty comfortable even if I felt that I needed to air my ears a little after all that.

Retail Price: Sudio Nivå retails at S$169, comes in black or white.

Sudio Tolv

Sudio Tolv is the upgraded version of the Nivå and they’ve really made some great improvements to it.

I love that the case of the Tolv is much smaller than the Nivå – it’s so much more compact and takes up less room than before. You do have to carry the case around with you to charge the earbuds and make sure you don’t lose them when you aren’t using them. I did leave my Nivå at home several times when I was trying to travel as light as possible, so I’m happy that the Tolv’s case is so much more compact.

More than cosmetic differences, the Tolv also has improved playtime at 7 hours at a go and 4 additional charges from the case, which means you could technically go for about 35 hours without having to plug the case in. That’s double the playtime of the Nivå where you only had 3.5 hours at a go – I’ve had to recharge my earphones periodically through long flights when I was binge-watching shows on my phone so I’m glad that I probably won’t have to do that as often now.

The Bluetooth range is also a little longer – 15m compared to 10m in the Nivå. 

Retail Price: Sudio Tolv retails at S$189, comes in black or white.

Jack-free wireless earphones

Sudio Vasa Blå

The Vasa Blå was my first pair of wireless earphones from Sudio. Like the Tolv and Nivå, it connects via Bluetooth and is pretty easy to pair with your phone or any Bluetooth device.

Mine are kinda scuffed from carrying around, but I love the bright cobalt blue colour. There are 4 earbud sizes in the box so you can choose the ones that fit your ear properly

The wires are flat which definitely does help prevent tangling as compared to my conventional wired iphone earphones. I have actually slept in these earphones a few times while in hostels to block out snoring when I couldn’t find my actual foam earplugs.

What I do like about the connecting wire is that it lets you sling the earphones around your neck – there is a clip you can use to secure it to your collar or hair so I can keep them on me without worrying about them falling out somewhere. I’m always quite scared about losing the earbuds of the wireless versions, like if it drops out somehow after I’ve fallen asleep.

I thought the sound quality of the Vasa Blå was pretty good – I’m honestly not enough of an audiophile to wax lyrical about the aspects of the sound quality, but I’ve had cheapo earphones with iffy sound quality and you can tell this is a quality product.

The battery life was decent, though my problem was that sometimes the battery would drain out if I hadn’t touched the earphones for a long time,  and I couldn’t use them until I recharged them, which is a bit annoying on the go but it’s easy to recharge the earphones with a portable charger.

Another thing about these sort of earphones is that you can’t use them on the plane unless you have an adapter (which I don’t) – so I was still stuck watching plane movies with cheap-ass headphones and getting tangled in wires every time I wanted to go to the bathroom.

Retail Price: Sudio Vasa Blå retails at S$129, comes in black, white, classic blue, pastel blue or pink. 

Sudio Tre

The other pair of earphones that Sudio sent me were the Sudio Tre, a more sporty version of the Vasa Blå meant for fitness buffs as the wingtip shape of the earpiece is meant to hold the earphones more securely in your ear, and it’s also sweat and water resistant for exercise.

The classic blue Tre is very different from the Vasa Bla blue! This is a very dark midnight blue that’s almost black

The sound quality I had no issues with, it was more the sound blocking that I had issues with. I’ll be quite honest – maybe because I’m not the sort who listens to music on earphones while working out – but I didn’t like this as much as the Vasa Blå. The wingtip does feel more secure in the ear, but my main issue is that the Tre is specifically designed to NOT block out sound completely for safety reasons, so you can still hear traffic noises while jogging for example. Great for safety, but that’s not quite what I want with my earphones – I don’t want to hear the loudmouth seat neighbour when I put my earphones in!

The earphones all come with a mic and the ability to take calls, though I haven’t tested that function as yet because I usually use them when overseas. The Tre is slightly longer than the Vasa Blå and I think the design is a tad more classy – the metal button interface gives is a more polished look, and that midnight blue is perhaps chicer than the fun cobalt blue of the Vasa Blå. The Tre is nice enough if you are an active person I guess, just that it’s not for me.

Sudio has since upgraded the Tre to the newer Sudio Tretton with a modified earpiece wingtip shape. 

Retail Price: Sudio Tretton retails at S$149, comes in black, white, classic blue or pink.

Some final thoughts

Overall, I think Sudio earphones are pretty good looking and the sound quality is good enough for me.

I would definitely recommend the Tolv over the Nivaå mostly because of the smaller case and the enhanced specs. The Vasa Blå and Tretton are also great options if you are a bit paranoid about losing your earbuds or you just don’t want to carry a case around with you – it really depends on your preference.

  1. I’m not sure if you will reply to this question as this post is a bit over a year old. Anyway, I wondered if you found anything with the Sudio Tre regarding its ability to connect via Bluetooth. When I bought the Sudio Tre about 6 months ago, it worked great for a fligjht I had to the US from the UAE. After that trip, I used the Sudio Tre with my phone, my personal laptop and my work laptop. However, now, they won’t connect to anything via bluetooth. I have unpaired them, let the battery go down to totally uncharged, repaired them, everything I can think of. Nothing works. None of my (or any of my friends) phones, laptops, etc. can even “see” my Sudio Tre buds. They are a very expensive failure at this point. So I’m hoping you have some advice for me…?
