The Difference

Between the T4S and the T4, the only difference is the lettering labeled “Turbine” on the housing. I got this information from a Bluedio rep on Facebook. Other than that, the headphones are identical.

Bluedio T4 vs. T4S

So what are you getting?

What’s in the Box?

With the T4 you’re getting:

  • The Headphone.
  • A Soft Carrying Pouch. For me this was much too small for the headphone and proved rather useless.
  • USB Type-C Charging Cable.
  • USB Type-C Headphone Cable.
  • User Manual.

Let’s move on to build!


The build of the T4S is really quite lovely.

The headphone is made of mostly metal and protein leather and feels quite substantial in your hand.

The ear cups rotate up and down, as well as 90 degrees outward.

They do not however rotate 90 degrees inward. It stops at the neutral position, much like an Audio Technica ATH M40x.

However, the headphone does not fold up like the M40x or M50x.

I wouldn’t call it bulky, but it’s a bit heftier than I would like for the gym.

The clamping force is very good for everyday portable use as well as home listening, but for working out it’s just not feasible.

The headphone tends to slide around way too much, and will even fall off if you sneeze or fart in the wrong direction. Lol.

Okay maybe it’s not that extreme, but the headphone has fallen off of my head many times in the gym from simply initiating a set of incline dumbbell presses or tricep extensions on a decline bench.

It’s just not practical even though I really wanted it to work.

The headband adjustment is quite solid, and the padding is made up of protein leather that feels fantastic to the touch.

I personally believe most, if not all budget headphones should employ this type of material.

It doesn’t break down, it feels nice to the touch, and remains very comfortable over long listening sessions.

The cups themselves are a sort of circular shape, with a nice depth that won’t result in your ears touching the drivers. What is a Headphone Driver?

On the top of the headband, there’s a “Turbine” inscription that matches the color of the band.


Fortunately, the Turbine comes with both a USB Type C charging cable as well as a manageable Type C headphone cable that terminates in a 3.5mm jack.

Manageable in this case simply means it’s the perfect length for everyday affairs.

On the right cup, there’s an Active Noise Cancelling switch for Bluetooth/Wireless use.

I have a bad habit of switching it on when the headphone is wired. Don’t be like me.

Bluedio T4 vs. T4S

Overall, the build here is above average and I feel pretty comfortable manhandling the headphone a little more than I usually would with other audiophile-type homies. It seems very rugged and not prone to breaking down over time.

When you put it in your hand, parts of it do feel a bit wobbly bobbly, so a few points are docked for that.


Let’s get into comfort!


Comfort here is also excellent for the most part. Just make sure to take any earrings out beforehand as you will start to feel them digging.

I find that my ears fit pretty well inside, but if you have Dumbo ears your mileage will vary.

The protein leather is the savior here.

They just feel really non-intrusive and snugly on your head, with a decent amount of clamp force for most situations.

Bluedio T4 vs. T4S

I was excited to finally replace my geeky-looking Skull Candy Uproar Wireless for the gym, but these won’t cut it in an environment like that, unfortunately.

They wiggle and jiggle too much like jiggly puff as if they have a bit of extra junk in their trunk. Or something. XD

You’ll find them sliding all over the place during an intense session, and it just doesn’t work.

The headband padding isn’t bad – I’d like to see a bit more on here, but at the same time I don’t find them digging into the top of my head which is a plus.

This is above average in terms of overall comfort. I find myself adjusting them less often than something like an SR850, MDR V6, or ATH M40x.

I think Bluedio did a great job here for most users.

Guys and gals with exceptionally large noggins might fare better at the gym than I did with regard to clamp force.

My head is big vertically but fairly narrow horizontally.

Back when I used to work at the Wal-Mart bakery, this one funny gal got semi-annoyed with me one day and told me to “Shut up with yo apple ass head”, as she was walking away to slice deli meat.

Lol. To this day it still cracks me up when I think about it.

So yeah, I have an Apple ass head, but it only looks that way when my hair grows out considerably. 😛


How do they sound?


Now for the best part, sort of. OK not really. Lol.

This is definitely a V-shaped variety, but it’s a bit less traditional than your average V-Shape headphone.

There’s your standard lower mid-range recession, but the mid-bass is also recessed while the sub-bass is, well, extremely elevated.

Bluedio T4 Review



Check out the RTINGS official Bluedio T4 Turbine Wireless Review!

This creates a weird roller coaster effect going into the upper mid-range presence boost around 2-3k. I find there’s a nice forward character about it, but after a while, the sound is rather clammy at times and kind of flabby/bloated, etc.

There are times when that extreme sub-bass works wonderfully; namely on EDM/Indie Pop type tracks and the like.

It actually sounds great with some old Michael Jackson recordings off of Thriller, but for Jazz and Classical? Forget it. Don’t even bother. It’s just going to sound awful.

Out of the ifi xCAN, you won’t even really need to use the XBass function at all.

There’s plenty of bass, and many times you’ll enjoy the sense of detail it provides, but it always seems like something isn’t quite right as far as an even sound.


The treble here is surprisingly good though; I’m not feeling overwhelmed by any unnecessary spikes or peaks.

It’s a fairly rolled-off affair but works well for long listening sessions because you won’t ever really become fatigued.

I think this was important in making the headphone somewhat salvageable at the end of the day.

This isn’t one I would personally ever purchase because it’s really hit-and-miss.

Some tracks sound phenomenal, and others are downright atrocious.

It’s an uneven and unpredictable-sounding Jekyll and Hyde type of scenario.

An example is Steps by Handsome Ghost.

There’s just too much mud being flung around, with little sense of space, depth, and air.

While not an incoherent mess, it’s definitely gravitating in that direction. The bass tends to overpower the mix in many cases.

Bluedio T4 vs. T4S

An example of a song that works a bit better is Kwassa’s “Hideaway” until you get to the chorus.

It’s just too congested for me to enjoy with any sort of consistency.

The treble is really its saving grace because you can listen for quite a while and couple with the great comfort factor, there are people who will undoubtedly enjoy this type of sound.

I’m not really one of those people, however.

It sometimes starts to sound unnatural and kind of awkward, because of that mid-bass information being absent.

On The 1975’s She’s American, you can clearly hear this weird sense that there’s a chunk of the sound signature missing.

The bass line is nice and articulate, but it lacks that punch that makes a lot of bass headphones sound intense and exciting.


Let’s take a break and watch a video!

Will you need an amp?


At 16 Ohm and 116 dB/mW Sensitivity, you’re obviously not going to need an amp, but I’ve been experimenting with various Amps and DACs that I have here at the pad. 

These include the xCAN (mentioned above), FiiO Q1, JDS Labs Element, and FiiO E10K.

Out of these, I think the Q1 is the best match because it’s meant for this type of headphones Impedance and Sensitivity rating, as well as really low Impedance IEMs. The Bluedio fits this category quite well.

So that’s that. Not much more to say here.

What about Genre?


Obviously, you’re going to want to stick with bass-heavy genres like Rap, Hip-Hop, Indie, Pop, Indie Pop, EDM, R&B, and generally anything that falls in line with those sorts of acts.

I tried some Jazz for laughs and promptly killed that with fire.

Walk Away by LANY is an example of a song that I think works very well with this headphone.

The bass line is deliberate enough to give off some nice impact, but not so fast that everything becomes a giant cluster f*ck.

You can clearly hear that vocal presence come to the forefront, and the treble knows its place.

It’s natural-sounding and doesn’t have that overwhelming sense of essy that you’d get out of an SR850 or something similar.

A similar track that has a nice, smooth treble, rumbling bass and some nice vocal presence is Love Myself by Etta Bond.

It just sounds appropriate with these headphones. I’m not really hearing that lack of mid-bass presence and everything sounds fairly natural, all things considered.

The bass is definitely accentuated here, perhaps a bit overly so, but it works given the track we’re rocking with.

What’s the final grade?

Final Grade


The B+ I initially gave on the video review was probably being very generous. 

While the build and comfort are very good, the sound is not something I’d ever recommend today.

So overall?

Probably a C and not recommended for most folks. 

What do I recommend instead?

I think Gravastar crafted a great IEM with an incredibly well-tuned sound signature.
