About iBasso

Well-known by audiophiles, iBasso is a Chinese brand of DAPs, amplifiers and more recently IEMs. After the DX150 and DX120, which we previously reviewed, it’s time to take a look at their new IT01S.

If you want to check our previous iBasso reviews, just go here.

The IT0X Series

Nowadays, iBasso produces four IEMs (including the IT01S) and one headphone. Here is a quick tour :


The iBasso IT01 has been reviewed by Berkhan previously.

With one dynamic driver, the IT01 is/was the entry level from iBasso, but to quote my colleague : “What the IT01 gives you is one of the best performances you can find for 100$. Great energy, good bass, crisp mids and treble with a perfect resolution for the price. I definitely recommend it.”


The iBasso IT03 was the first IEM from the brand.

It’s a hybrid model with one dynamic driver and two balanced drivers, all arranged with a 3-way crossover. The shell is made of acrylic and adopts the popular CIEM fit to ensure the best comfort for the user. We for some reason never officially reviewed it on Headfonia but I do own a pair and for the asking price, it’s pretty good.


The iBasso IT04 is the flagship :  triple balanced armature drivers + one dynamic driver.

Again, Berkhan reviewed it and he said : “And moreover, it achieves to be the best IEM I’ve experienced for 500$. What does it mean? It means that it dethrones the Noble Savanna and takes its place in our recommendations. It fits better, sounds more versatile and all around, and it has better bass. So replacing the Savanna with the IT04 is a no brainer for me”


The iBasso SR1 is very special.

First, it’s a headphone and not an IEM, second it’s a limited version only available in one batch of 500 pcs. Unfortunately I haven’t got one, but I think I’m gonna buy it one day, out of curiosity. To sum it up : it’s a semi-open headphone with a Tesla magnetic flux driver and Bio-Cellulose dome diaphragms. Yummy !

And now, iBasso has added a new model to their line-up : the IT01S. Time to dig in.

A nerdy guy with a passion for audio and gadgets, he likes to combine his DAC and his swiss knife. Even after more than 10 years of experience, Nanotechnos still collects all gear he gets, even his first MPMAN MP3 player. He likes spreadsheets, technical specs and all this amazing(ly boring) numbers. But most of all, he loves music: electro, classical, dubstep, Debussy : the daily playlist.

    Thank you for fantastic review. How would you compare IT01s to LZ-A4? I can get them both in good price and can’t decide. I’m looking for fun sounding signature to use them on daily basis, with lg v30.

    Hi, I am a happy use of these iems but unlike you I always get a background noise that is annoying with the kind of music I listen to (jazz, classical, flamenco…). So I use a iFi earbuddy, which is great, but then I worry about loosing some texture and details. Any advice?
