Replaceable Cables

A pair of headphones with a replaceable cable has many benefits, and one of them is if the connecting cable has a problem, it doesn’t mean that you have to buy a new one. If the connecting cable gets pulled or damaged, you can replace it and keep using your good-old headphones or IEMs. This way, your headphones will be protected and will last longer. With the advancements in cable manufacturing, you now get a variety of replacement cables with various termination options, lengths and quality.

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!
