Bloom's Take

It’s easy to get lost in the constant release of high-end IEMs and forget the level of performance you can sometimes find at lower price points. UCOTECH RE-2 is the quintessential example with HUGE value at an insane price. We brought RE-2 to CanJam NYC 2023 and were overwhelmed by the community’s response to this $109 IEM from a virtually unknown Korean brand.

The RE-2 keeps it simple with a balanced, neutral tuning that doesn’t lose sight of musicality and engagement in its pursuit of accuracy. You get a lifelike, natural sound that absolutely blows away your expectations for the price, and a versatile IEM that makes for a near perfect daily-driver for almost no budget.

Ucotech, Quality from Korea

Ucotech has been around since 2007 and are known for their amazing earbuds and earphones that are made with passion in Korea. They are known to make quality products, specifically masterfully tuned earphones that are solid built with a well-thought out design.

The RE2 has a matte, anodized gray shell with gold finishings along the faceplate edges. The build is similar to the Ucotech RE-1 Pro, but the RE-2 nozzle has an angled trajectory for a better fit and feels a bit more solid in your hands over the RE-1 Pro.

It's equipped with a 10mm beryllium plated driver famous for quick transients and sweet, distinct, detailed highs. Beryllium is a costlier material and challenging to work with hence the slightly higher price tag over the RE-1 Pro.

The cable included is a litz silver-plated OCC 4-core and looks superb for the price. It presents as very thin, but don't let it fool you as it sounds decent and ironically presents with thickness in the sound profile. We had the best listening experience with lower end, non-flagship DAPs and DACs like the iBasso DX170 and Questyle M12.

Good, but not great

For the price there are better ones but these are nice

Superb DD IEM !

Fulfils my expectation of a neutral sounding DD iem. Very mature sound. Kilobuck iems should learn from ucotech. Slight roughness is there in the starting but goes away after burn in & tip rolling. Pairs (scales) well with desktop OTL amp without any FR issues.

At least better than other brand ranged at 300$

I have owned few headphones ranged between 300$.
This RE-2 I was trying in a shop shop and the salesperson introduced this model to me and that was the last one in stock.

Wow. I was impressed by the mid-range and clarity. The bass is also well-controlled. Very enjoyable to listen. More amazed me is the price (just 130$). I was not quite sure as it is so unreal. So I tried other brands e.g. Shure Aonic 4 and Sennheiser IE300. After few hours of careful testing, I'm sure they are far less impressive than this Re-2.

Look at this RE-2. The core build is already very solid and the default factory cable is thick and fancy. Material-wise it's already better than Shure and Sennheiser in 300$ price range. I also have a flagship of Bluetooth Earbuds from ATH. Re-2 is still slightly better.

When I bought a new one, that sound was a bit too hard and not wide enough but after few days, bloom! Re-2 is even better and I feel 120% glad to have this RE-2 in my collection. Now I keep listening day by day with full happiness.

I need to tell to more people as a good quality headphone must gain more attention so that they can do it even better.


Non Harmon. great soundstage dynamic natural bass that actually sounds like drums etc. A bargain.

I mean what the heck. Just buy. Night and day vs the re-1 pros from the same company. Honestly I think Ucotech priced it wrong. Never been an iem guy altho I own a few high end headphones. I am listening to my music collection all over again. Very detailed and satisfying to listen to.
