Customer Reviews
This is an excellent pair of IEM. Everything is just perfect, Highs, Lows, Mids, Details….Everything. Worth every penny. I use Tripwin Petrichor 3.5mm and ifi Golink with this. I have 1Custome PM01 as well. I find 1custom junior better sounding than PM01. Became a fan of 1Custom after using this one. I have IE300 as well but this one has its place. So smooth and immersive experience.
Glad you loved the sound!
After using plenty of earphones this is one of the best Earphones. The sound stage is very wide of an IEM and also the clarity and details are very good given the price point. The bass is tight and punchy not bloated or heavy at all. I am really happy with these ones. Dont think I will find anything better than these.
Hi there! Thank you so much for taking the time to leave a review for the 1Custom - Junior.
coming from Shure SE215, this is a huge upgrade! sounds really clear and wide
love the two switches! I found the mid-range to be a bit lacking in the 'default' mode, but the 'vocal' switch really makes a difference
also a thanks to Shlok at the headphonezone office who helped me pick between the IEMs I was considering
Thank you for sharing your experience with the 1Custom - Junior! We're glad to hear that it was a significant upgrade from your previous Shure SE215. We appreciate your feedback on the mid-range and are happy to know that the 'vocal' switch made a noticeable difference for you. We will also pass along your gratitude to Shlok for his assistance in choosing the perfect IEM for you. Happy listening!
This is a very special IEM. In my opinion this IEM has the widest soundstag of any iem. They wowed me the first time i heard them. They have a great tuning as well.The soundstage is wider than well known IEMS that cost more then 2Lakhs and even higher.
I couldn't find any FR response graph though.
The accessories are a bit cheap. The cable is really bad and you get only 3 set of eartips and that's all the accessories you get. The build quality seems meh. I'm a little concerned over the longevity of the IEM.
Hey there,
Thank you for taking the time to write this detailed review, we really appreciate the genuine feedback! Your review will definitely help fellow audiophiles to make an informed decision.
The one custom junior is a very good iem. I used it with a shanling UA3 and tripowin zoonie 2pin balanced cable, it provides lots of detail in music with balanced output across all frequencies. I personally liked the bass setting. I highly recommend to every person who is seeking to enjoy hi res music.
Thank you for your review! We're glad to hear that you are enjoying the 1Custom Junior with your audio setup. We strive to provide high-quality products at a fair price, and we're happy to hear that you feel the price is justified. Thank you for recommending our product to others who enjoy hi-res music. Happy listening!
1Custom - Junior
Hey there, thank you for the awesome ratings!
Bit bulky but worth all!!!
Super details, techno EDM , but make sure its paired with Amp Dac to receive the full potential. Initally i was doubtfull if its worth the amount i am paying for, but trust me you will receive exactly what you are paying for.
Will totally recommend.
Good recommendation from Headphone Zone!!👍🏼👍🏼👍🏼
Hey PARTH, thanks a lot for this lovely review and we are glad you are enjoying it! Keep the music playing.
Best value for money. Soundstage is wide and detailed. I am using it with ibasso dc04 pro which makes it a formidable combination. It does have bass and sub-bass in right amount according to my preference and liking. I have only tried with apple music with lossless hi-res audio which delivers very detailed sound quality. Going to try to with 4.4mm balanced o/p.
Hey there, thank you for the great review and ratings! So delighted that you are loving your purchase. Hope you had a comfortable shopping experience. Cheers!

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.

You can expect these headphones and devices to connect seamlessly without any hassle and even offer OS-specific functionality depending on the device. Headphones and devices designed to work with Android and iOS come in wired and wireless formats. Quite often you will also find Hi-Fi equipment offering direct connectivity to devices with Android and iOS to simplify the connectivity process.
Tangle-Free Cables
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.

DESCRIPTION
HYBRID TRIPLE DRIVER SETUP WITH TUNING SWITCHES FOR CLEAN AUDIO
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. 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.
DETACHABLE CABLE WITH 2-Pin CONNECTOR AND ACCESSORIES INCLUDED
The 1Custom Junior comes bundled with a detachable cable with an 2-Pin connector. This cable is made of high-quality materials, allowing for transparent and detailed sound transmission.
