An IEM With Ultra-Wide Soundstage

Hybrid Triple Driver Setup

The 1Custom Junior is designed with utmost precision for the best audio reproduction. 1Custom Junior features a hybrid driver configuration with two different types of driver technologies. It comes equipped with a single dynamic driver and two balanced armature drivers. With this, the earphone presents a high-resolution outcome. Each of the drivers is independently fine-tuned for a wide soundstage with lesser resonance.

Tuning Switches For Clean Audio

There are also tuning switches on the IEM allowing you to tweak the sound to your liking. You can feel free to play around with the tuning switches and discover your preference. They are pretty effective while not overpowering the other frequencies in any way. The structural design offers more consistent sound across all frequencies to deliver shiny highs and deep bass.

Ergonomic Design For A Comfortable Wearing Experience

1Custom Junior has been designed keeping comfort in mind. The redesigned 1Custom Junior features an ergonomically shaped earbud which allows for a secure and snug fit. This new design allows the earbuds to ergonomically conform to the curvature of the concha offering a better fit. The shiny coating on the buds ensures the longevity of the sheen of each shell. The 1Custom Junior also has metal nozzles that have a lip. The lip will be useful to ensure that most ear tips will stay in place and not slide off and get stuck in your ears. This allows the nozzle to sit more closely to the ear, making it super comfortable to wear for long listening sessions and do not cause any fatigue.

I first thought that the customizable switches were a gimmick. But they're not. My favourite setting is 'Detail'. It's incredible the detail and nuances that this IEM brings to the table. But the USP for me is the ultra-wide Soundstage. I haven't heard that on any other IEM.

RAGHAV SOMANI

If you’re looking for a comfortable IEM with switches to slightly tweak the sound, a nice build quality, I totally recommend getting the 1Custom Junior IEMs from them.
The stock tonality of the Junior is on the slightly brighter side, but it does offer a smooth bass region and a euphonic midrange with a wide soundstage.
The 1Custom Junior from Jaben Singapore has an excellent value. The Bass is quite beautiful, with an excellent amount of impact, a nice sub-low extensions, mid-bass presence too.

Bliss to my ears

The Custom Jr has a great fit & is comfortable enough for long listening hours, being fairly easy to drive. It's easy to pair it with anything, Though the wires do not have a mic, its not much of an issue for me. I generally use this pair with my FiiO BTR5 & the experience is surreal. Thank you for Headphone Zone for the quick delivery & the playlist cards were just the best

Thank you for the great review & rating Sakshi!

Excuse my French, but they are f****ng marvelous!

I tried all settings, the difference is 5% or so, really subtle. I am just going to mention the setting with max bass. The bass is tight with fast decay, not meddling with lower mids at all. Vocals are amazingly natural. Highs are extended, airy and detailed.

Soundstage is wide as a playground. I think I am in love with these IEMs. Special thanks to Danish from headphone zone who guided me to these over FD3 and FH3.

We are glad that you are liking the product & had a good shopping experience with us. Thank you so much for the amazing review & ratings, Ankur Oberai!

Mesmerising Earphones

Just Amazing - After attending the Headphone connect at Hyderabad, I ordered these and these are just amazing - no words.

I am writing below line after using this product for about 2 months - the built quality is not that great - I was trying to change the wire and pushed it slightly in to its holder on earbuds and on one of its ear but the holder got broke - it was just a slight push. I did not expect this.

In Love!

Owe you guys one for getting this to India. The packaging is bare-bones but the sound makes up for everything. Would recommend this one any day over your mainstream chi-fi iems

Delighted to know that you are loving this IEM. Cheers!

A gem of an earphone

I am not much into earphones and basis of comparison is with a shure 215 and Astel and Kern Billie jean. This is warmer more detailed and with a deeper and cleaner bass. loved it using the Detailed setting. I now use it with the Shure True wireless module and its a great match so far.

We're really happy that you have such great thoughts about the product and thanks for the amazing review!
