These are very comfortable with a nice feeling cable that isn't very microphonic. Sound is a bit laid back with slightly recessed mid range and elevated bass and treble. Resolution is on par with other offerings in this price range which isn't a lot. My primary use case is Netflix and Spotify with DD TC35B which is more than adequate for my needs.

I received my ibasso IT00 earphones today. It is supeeeer quality product. Very nice sound quality with respect to high mid and low.. HPZ service is super fast.. i get headphones within 24 Hrs..

BASS:
Unless youre looking at very high price points there is no doubt that delivering a clean, non bloated powerful sub bass without too much emphasis on mid bass is an extremely hard thing to do.
You always end up chosing between unclean but powerful bass or precise but anemic.

Here however the bass is felt not just heard and its fast and tightt and precise.
Bass guitar hums in you ear canal and sounds great.
Kick drums have the much needed punch.

This is the most satisfying bass Ive heard in an audio product, be it iems, speakers or headphones.(feel free to judge me ;) )

MIDS:
The lower mids and male vocals outshine upper midrange female vocals because of the bassy tuning of the iem the,vocals are completely clear just that someone who likes the vocals to sound more forward will feel that they are hiding with the instruments, this was fixed with some eq bg toning the bass down, and vocal centric songs sounded livelier this way.

TREBLE: Not the most detailed or sparkly but completely non offensive and easy on the ears.

INSTRUMENT SEPARATION:
Nice, its nice, no congestion felt for even when some songs get crowded with many layers.

SOUNDSTAGE: For an in ear at this price its freaking greattttt :D.

Recommended genres with default tuning:
House, trance, dubstep, techno pretty much anything that isnt live and vocal centric but it does fairly well with that too.

VALUE FOR MONEY:
For 6k I also have the ath e40 and ibasso competes well with that, even outshines it in some ways but is not as good vocally.
I will conclude that its pretty good value for money until I find something cheaper and better which is good at the same things that this IEM is. Which frankly speaking is a very very hard task.

HEADPHONE ZONE SERVICE:
The passion for sound shows, in the delicacy and thought with which each delivery is handled, I feel a great sense of happiness knowing that our country has companies that wanna give a taste of good audio to people. Well done guys :)

This IEM is a chef's kiss, if chefs ever got into cooking IEMs that is.

Blind buy without any doubt if you are looking for clarity and overall tonality.
Best for HIP HOP, EDM genre and not bass heavy tho but the sound is smooth as butter.
Pair it with DAC and it will sparkle more.

One of the best IEM's under 10k. Fast bass, great imaging and decent soundstage. For 6k these are an absolute steal. The only pair I'd rate above these are Astell & Kern Billie Jean.

Previous Experience with IEMS: none
Previous experience with Over the ear Headphones : Bluedio T3/F2, Sony WH CH710N

As most of you guys can make out , I'm a newcomer to Hi res audio and world of DAC/AMPs

I bought a shanling bluetooth DAC/AMP along with these pair of IEMS..

The experience is beyond words for me as a first time user

First time I felt a sound stage with sounds distributed around my head..crystal clear separation of different instruments..many of them never noticed before..!
there is a more "human" or "real life "quality to the sound than the experience I had with my previous headphones.. Has enough bass for my needs. Fantastic treble and decent mids. Good noise isolation. IEMs are very lightweight and comfortable ..

Thanks for the recommendation..

I was little skeptical before buying it, as this was my first audiophile iem and I went over every review I could find over the internet and ibasso it00 was always there.. it is as it says in those reviews both positive and negative. And at the end it's value for money.

Burnin is essential to get the best out of these.
The difference was stark. Well I didn't put them for 2 days on but somewhere near 20 hours.

The Built -
It is super light weight but strongly built.
The cable is extremely good and doesn't have a rubbery or sticky feel.
It feels really good to touch and wear.
Also it's pretty and plenty long for comfortable outdoors.
It gets entangled, but not much.

Looks -
It looks absolutely elegant, minimal and premium built.
It isn't as shiny as a Blon 03 or flashy as a KZ iem or metallic industrial design like the Tins.
But it has it's own unique personality. Definitely a head turner.

Comfort -
Ohhh Boyyy! These are freakin comfortable and feels like nothing on the ears.
The cable doesn't come in the way. It is light enough to not pull the iem down or move the iem.
Isolation is on point. Once the music is on you can't hear anything from outside.

Sound -
These are very sensitive iems. They don't need much power to run.
Infact they were at full potential at just 25% volume on Macbook Pro and 60% on LG V30+.
It was equally good for all frequencies. These have a warm signature but with great clarity in the mids.
Nothing is sacrificed as such. It's a pleasure listening to them, I don't feel like taking them off my ears.

Treble -
The high ends are so amazing, pleasant and non-piercing.
I was surprised how some of the high-pitched songs sounded so good on these without a fatigue.
I had them on for atleast 2 hours straight up without a discomfort. They are easy on ears even at high volume.
I don't know how it does that, but truely amazing.

Mids -
The mids are so clear and forward. Vocals are aggressive and doesn't get muffled by the bass or the highs.
Instrument seperation is amazing. Aretha Franklin and Ariana Grande sounded just so great.

Bass -
I don't know why people are saying these are bass heavy.
These don't have an over-powering bass at all, but a very clean low end.
The bass is pleasingly boomy and punchy. It's not muddy at all. Enough power at low end to enjoy EDM and Hip hop.
But it's definitely not for bass heads. It doesn't sound like Sony or JBL's.
Soundstage - Ohh Boyyyy! It's so good. Thriller by Mj was an utter pleasure listening to.
Also John Wick Parabellum trailer sounded amazing, with the bullets hitting ground and car crashes.

What I didn't like -
I wish it had at least a mic.
The cable connector is very tight.
Yes it's secure and sturdy but it's also a pain to take the cable off. Require strength.

The sub-bass reproduction is great & the bass texture is rendered smoothly. Mid-bass is punchy & there is a tight presentation. Midrange is slightly warm with good clarity and the highs are detailed. There is no sibilance and harshness. These have natural soundstage with good width. These are fun sounding IEMs.

These are not earphone this is a challange which you can buy and throw it to your phone ..... I will bet on these earphones 100 out of 100 times that your phone can't beat be whatever EQ or Poweramp or dolby setting you change but you won't hear anything other then the bass.

Using FLAC files with poweramp (paid) on oneplus7T.

My initial plan of upgrading things have taken a beating.

Potential buyer ... Save your money and buy half the the price earphone so if it fails you will be heart proportionately or save some more money and buy bose Soundtrue and you will not be disappointed with it.

The best controlled bass in an earphone you can find just right amount of bass, the treble might be a little high for some but overall a great piece of IEM.

IT00 is a Balanced iem for listening music in a very enjoyable sound signature. Bass, mid and high are turned very nicely. Very clear and soft sound. Does not hurts ear in high volumes. All frequency band is clearly audible at very low volume also.

I was purchased this as an exchange ofer against Tripowin mele, which was very muddy sounding earphone. Totally satisfied with the sound quality of ibasso IT00. Only problem I occurred is
a clicking noise coming when inserts to ear.
Thanks Headphone Zone for giving a chance for exchange and also providing this great IEM.

This could be the best choice if chosen blindly. Build quality Top notch. Best bass reproduction, probably the accurate. Bass delivery is quick, Tighter and does not bleed into anything. And other sounds are all pristine. Everything is accurate, you can hardly find any flaw or it does not allow you to find any and engages us into the music we are listening in the best enjoyable way. For the Price it's Bang for the Buck.! This a no brainer for recommendation. Once again HPZ epic label on products "OUR PICK" has not failed. My top performers:
1. IKKO OH10
2. KZ ZS10 PRO
3. KZ Dq6s HBB
4. CCA C12
5. TIN T3 Plus
6. Soundmagic E80c
7. Shuoer S12
8. I Basso IT00
I Basso IT00 is best among all now and suitable for long listening sessions. E80C and S12 require more power to drive and give their best, they also will be best suited for safe sound for long listening.

best
