Hands down the worst after sales service!

WOW, where do I even start with this horrific experience with HEADPHONEZONE:
the only reason I have given it a one-star rating is that I can't give the rating in minus.
I ordered these iems thinking that they would be a quality product and also taking into consideration that the rating was high for them.
the sound was mind-blowing but it didn't last for long, in only 3 weeks the left side bass went flat and I notified the headphone zone about the issue.
And from that point on the real nightmare started. this company is run by amateurs in client service who have no clue what quality after service really is.
I had to wait almost a month and constant checks through 30 odd emails to get updates on whats the status of the procedure.
so after reviewing the unit from their warranty side and the headquarters site, they have come to the conclusion that there is no defect with iem and the unit is definitely perfect.
so yes the customer, in this case, is definitely a beggar who has no choice but to accept a below-average after-sales service, and there is definitely something wrong with their ear or head or both. that they had the audacity to send the unit back to headphone zone , expecting a great resolution and top-notch after-sales service.
honestly, my bad that I accounted headphone zone for high standards in ensuring a quality product and after-sales.
so you can keep your "not so defected iems " I will not accept them.
Thank you.

Hey Karan, we're sad to hear that you are not happy with the warranty experience for your earphones. As this is an electronic product, it can tend to have issues with time and that is the reason there is a warranty period to help you out in such a situation. We always aim to give you the best possible resolution as we believe that you've put a lot of trust and faith in us when you've purchased a product from our website. We really regret the delay in your case due to the lockdown and believe us, if the unit actually had any issues, we'd have informed you the same as we did multiple inspections especially in your case. However, we do understand your concern as you faced the issue and we tried our best to resolve your case.

Musicality and tonality over technicalities. Instant oppoty 🤣

First ,thanks headphone zone for a super fast delivery and bringing this hidden chifi gems here at almost same price point.
Fits me perfectly with supplied tip (the larger one),no issues.
SQ- Brilliant tonality. Lively, engaging, exciting. Incredible value. What a lush tuning.
Yes, definitely, around 30 percent of reduction of bass would be perfect,but wait ,use wavelet app , use the bl03 fr graph for corrective eq at 40 percent intensity to achieve the harman target (almost),if that is what you're looking after. Or simply eq down some low end. And that's it . Rest is pure gold for the price,even for 100usd. Lush,warm,thick mids , slightly rolled of but sweet sweet treble without any shouty ,peaky, sibilant harshness. It's a forgiving set , it's relaxed , musical and inviting .
Though lows are elevated ,its fairly textured and nuanced,just a bit slow . Wide staging ,good 3 d presentation, surprisingly good depth.
Extremely efficient, no need for extra juice, it's happy with the output of any modern smartphone or dap.
Great for long ,non fatiguing music sessions even at high volumes.
Overall, don't buy this for it's technicality,though it's no slouch but from purely technical standpoint you'll be better served with Tinhifi t2 or t4 or Etys etc. Buy this to get lost in your music ,not analysing how many micro details you can retrieve. It's not the point of this baby.
Overall, If you want one warm , slightly bassy ,forgiving , relaxing, beautifully tuned iem ,I assure you ,it will fulfill your driams and open up new oppoties to fall in love with you favourite tunes once again.

Hey Chayan,
Thank you for the detailed review man. We appreciate it, happy to know that you had a comfortable shopping experience. Cheeers!

Incredible for the price highly recommend picking it up before it goes out of stock

My previous headphones were the Soundmagic E10-Cs which I had used for 2 years and they finally died off because the plastic coating started to break. It took a month after the plastic broke for the bare wire to finally stop working. (Should give you an idea of how well they were built).
These BLONs sound heads and shoulders above the E10C.

Music I mainly hear: Prog, Folk, Western and Indian Classical, Metal, Classic rock and UK Grime/Drill

My comments:
• Packaging felt great and the weirdly translated English is funny.
• Much cleaner sound and a very nice soundstage compared to the E10C. It is very well balanced I can definitely hear tiny details in the music I would normally have missed. Most noticeable improvement were in Prog and Classical music.
• It has a good sub bass which I was never able to hear in the E10C this was very noticeable in grime songs.
• Build quality seems great it is a full metal driver body that feels sturdy.
• Wire seems good nothing to write home about. It is a soft, braided cable. I've read it can be easily replaced by a after market 0.78mm 2 pin cable. Haven't tried this myself.
• The memory wire is totally fine for me so far honestly don't understand the complaints.
• Fit for me personally is totally fine. I've heard people complain a lot about the fit however I have smaller ear canals and it fit me great out of the box. YMMV if your have big ear canals.
• Decent isolation (probably better with foam tips). Again read online that people consider its isolation to be poor. I never encountered this perhaps because it fit me fine.
• Comes with a jute carry bag looks pretty nice.

Finally I'd say this is amazing for its price I don't think the average music listener can get a better bargain than the BLONs at this price. It is better than anything I've heard so far.
I'm not rich enough to talk about it from the audiophile perspective 😂.
Don't miss this oppoty.

Hey Bhoris,
Thank you for the great review!

Bhupendra (Pune)
These are good

So let me put this straight. I am coming from Focal Spark and sr850. Mic on focal went kaput within a few months and both the metal casings popped open last week. For a brand as renowned as focal, the quality turned out really bad. No complains on the sound quality though. Even the mic was really good while it worked. It's just that it worked for only a year. Anyway..

This started my hunt for something better than spark that also comes with a mic. After looking at the reviews online, I was lead to the BL-03/BL-05.

After reading reviews, I realised that BL-05, although more expensive, aren't better per say. They are just different. So I decided to buy BL-03 from headphonezone instead. When I first got them, I was fairly excited but the first impressions turned out to be bad. There was no bass, the isolation was non existent and I am comparing them with semi open sr850. I could literally hear the everything! So yeah, I was instantly turned off and decided to give it to my wife. Well.. she didn't like it either so I went back, looking for another pair.. while searching online, I was still listening to a few songs on the BLONS and it occured to me.. that the fit is the problem.. so I swapped out the eartips with.. larger size tips and all of a sudden, I heard some bass thumps. I kept tinkering with different sizes, shapes and forms and finally hit the sweet spot. Now I was hearing the sound I have paid for. These have really good bass. It's not super detailed but it grabs good amount texture from the low end. Now, I am not comparing bass with cheap senhiser buds so don't think it's only meant for bassheads. I am not a basshead but I do like the clean sounding, slightly V-shaped sound. The mids are as good as focal and highs are equally bright. That says a lot. So all earphones you have heard in 2k price bracket, these will perform better.

Mic quality however is not praise worthy.. it works and that's about it.

Now, here are tips for intrested buyers.

The fit is bad and you will have to buy new eartips for them. They do come with a slightly longer eartips but that did not work for me. I used to wear medium size but for these, I wear large. Do not buy SPINFIT CP240 thinking they sit deeper and will help you with isolation or a better fit.. They muffel the bass and treble entirely and that's really the biggest selling point of BLON BL03. I managed to get a homegrown solution and I'll put a few pictures. I think CP100 will be better but don't take my word for it. I haven't tried them and I have ordered memory foam tips instead.

Look for something shallow that barely protrudes from the nozzle but it should fit tight in your ears. This will produce the tight bass and not drop mids and the highs.

The cable will be a problem for most. It's a foot short and the way it fits behind your ear will tend to push the earphones out. I can live with it. I literally put premoulded plastic strips in boiling water and moulded them per my fit.

The isolation is poor so you will hear every honk and every noise while on the move. I ride a bike so I prefer semi good isolation.

You can't sleep with these on.

The .78mm 2 pin connector is not readily available on indian shores. I have ordered another set from china with a straight cable. So I can put them straight down. The over the ear position will press behind your ear and you will lose the seal.

Don't be careless with these, thinking it's all metal. Because it's not and the pin connector will crack if you aren't careful.

Soundstage is better than any IEM I have heard so far.

Willing to spend 2k? Stretch your budget and get these instead. Do not import from China, headphonezone will provide local warranty.
Thinking about buying another Chi-FI? Don't waste your time and get these.

You don't need to turn the volume half way to get the details. I am mostly at 30% volume on my cell phone and they sound just as good.

Why 3 stars? Because the accessories don't match up to the quality it offers. This is the first headphone out of hundreds, that required tinkering. The focal Spark were equally good and we're cheaper.

Burn-in is a myth. Put better tips.

Thanks headphonezone for providing speedy delivery.

Blons have crazy worse quality control

The time I ordered them.....the wires were faulty.
After waiting for 10 days I got my replacement (slow headphone zone) .
Even the replacement unit is faulty. Theres a clear imbalance in the left and right earbuds and the right one is even making creeking sound while putting in ears or tapping it.
Check your units before sending it over headphonezone.
I am disappointed.

Hey Arya, Its sad to hear that you are facing issues with your replacement unit as well. This is a very unlikely situation and we are extremely sorry about the same. As it was a brand new sealed unit, we had no chance to check the working before dispatching it to you, otherwise we would not have dispatched it in the first place. But do not worry, our team is already in touch with you to help you with a solution.
