Tanchjim has joined hands with Effect Audio to co-engineer an absolutely amazing pair of in-ear monitors, meet the Tanchjim x Effect Audio Force. It employs a dual dynamic driver configuration with DMT4 Ultra series dynamic drivers developed by Tanchjim. The pair features a 10mm and an 8.2mm dynamic driver on each side. Tanchjim has used HPFD-SEF precision segmented crossover technology to get the best out of these two DD units. Additionally, the pair has an open-back style design with CNC-machined aluminium alloy face covers and transparent resin ear shells. The pair comes with a premium silver-plated single-crystal copper cable co-engineered with Effect Audio.

The Magic of Two Dynamic Drivers:-

With many successful releases like the Tanchjim Origin, Oxygen, etc., where Tanchjim featured a single dynamic driver setup, the brand has shown its proficiency in designing brilliantly tuned IEMs. Tanchjim Force takes that proficiency to the next level with its dual dynamic driver configuration. The pair features DMT4 Ultra series dynamic drivers designed by Tanchjim. It houses a 10mm and an 8.2mm dynamic driver with composite metal-coated dome diaphragm materials. Experience rich and detailed sound with amazing clarity and ultra-low distortion with the all-new Tanchjim Force.

Professional Crossover For Clean, Low-Distortion Output:-

Through the HPFD-Seg High-precision frequency division technology, the sound of the Tanchjim Force is optimized to deliver outstanding clarity and rich tonality. The 8.2mm driver adopts a PU suspension edge composite dome diaphragm, which handles the midrange and high-frequency segments, while the 10mm driver adopts a PU suspension edge titanium-plated dome diaphragm. This 10mm dynamic driver unit produces an impactful and strong lower-end region.

New Cavity Structure With Open-Back Design:-

Tanchjim Force ear shells are crafted using highly precise FEA(Finite Element Analysis) simulation technology. They feature an open-back design with an ergonomic and comfortable shape. The pair adopts CNC-machined aluminium alloy face covers with transparent resin material inner shells. The pair strikes the perfect balance between comfort and premium feel.

Tanchjim x Effect Audio Co-Engineered Cable:-

Tanchjim has joined hands with the Ace cable manufacturer, Effect Audio. Together, they have designed a high-purity silver-plated monocrystalline copper cable for the Force. The cable wire cores are derived from high-purity UP-OCC technology. It features 4 strands of 26AWG single-crystal copper silver-plated wire cores. The cable is hand-woven for perfection. This cable has 0.78mm 2-pin connectors and adopts a swappable termination plug system as well. Tanchjim bundles 3.5mm, 4.4mm, and Type-C plugs in the package.

Extremely Comfortable And Extremely Durable:-

Tanchjim Force IEMs are extremely comfy and extremely durable. They have an ergonomic, lightweight design for the shells. Furthermore, Tanchjim has also designed the pair with an air pressure relief structure in the nozzle. We also have a dust and waterproof filter on the nozzle that protects the internals from dust and water splashes.

Unlimited Possibilities with Application Integration:-

Tanchjim Force when used with Type-C plug has complete integration with Tanchjim application available on smartphones. It unlocks unlimited possibilities with graphical EQ UI, Community to share and apply different EQ profiles, etc.

Easy instructions, comfortable cushions
Color: Pink
I just put it together and I love it!!! It's so comfortable and it was easy to put together. You can rock it back and forth which helps your back. The seat is very wide and the cushion is thick. Pink is my favorite color, and this chair satisfies my pink obsession.

Wonderful chair
Color: Dark Black
I bought this office chair as a sewing tool, you might say. I felt that having an office chair on wheels would get me from the sewing machine to the ironing board and then to the cutting board and back to the sewing machine. I was having to get up and down to get around to all these places before and this saves me so much time and effort. I’m 71 so when the box came I was hesitant to try to bust into it and put it together but it went together so easily. It’s very comfortable and the lumbar support feels great on my low back. When I first sat down after the assembly process, the chair cushion tipped down in the front but after contacting the support team I was advised to tighten the tilt tension located under the chair and that fixed me right up! All and all, my chair is the perfect addition to my sewing area at a very affordable price. I couldn’t be happier!

Comfortable, affordable, and great for small spaces!
Color: Light Purple, Color: Light Purple
I had previously left a review of two stars, but have since deleted that review after I've owned the chair for a few weeks now. Initially, I stated the chair was uncomfortable and not cushioned at all. But this issue quickly resolved after sitting it for a longer time, it seems the cushion molds to you. So it may be uncomfortable the first few times sitting on it, but it eventually softens. The cushion is now soft yet sturdy. You don't sink in too much, but it's comfortable for sitting for long periods of time. I personally enjoy the mesh back as well, it supports my lower back and doesn't cause back pain. Normally I have to use a cushion of my own to support my lower back for most chairs, but this one actually supports me in a way that doesn't require an extra cushion - so that's really nice. The chair is fairly on the smaller end, which is perfect for low desks or tight spaces, which is exactly what I wanted. The height can be adjusted, but even at the highest setting, it is still fairly low. Keep that in mind - it may not be super comfortable for those over 6 ft. The arms flip up which makes storing it under a low desk very easy. The cushion is thick and very accurate to the picture. I love that it is lightweight and doesn't make much noise when rolling the chair. It also feels very sturdy. Some of the reviews say it feels flimsy, and I don't know if some are just assembling it incorrectly, because for me this thing is very strong and holds up quite nicely under my weight. Overall, this is exactly what I wanted for my personal living space. A chair that's not too bulky, but comfortable enough to sit in for long hours. It functions as advertised for this purpose. One final thing -- the color selection is gorgeous. I bought the light purple color and it fits my setup nicely! Color was accurate to the picture, and looks very cute and adorable in my space.

Surprisingly amazing chair!
Color: Pink, Color: Pink
tl;dr: If you need a chair that has the features of this one, then this one is a winner! Hits above its weight class for sure. My wife is 5’. She’s small. For whatever reason she ended up with a chair made for big people, like 6+ feet and up to 500lbs type of a chair. She’d often even sleep on it and chill on it. The chair was big enough to fit 2 of her to be honest. It was an expensive chair that I won at some raffle and didn’t like myself. Over the years it ripped (got a cover for it) and even started to get lopsided (from the sleeping) and finally a spring broke (hence the pillow on it in the pictures) She obviously lives pink. I also wanted to get a chair where she could work and not end ip asleep on. Not like we have a couch or a bed for that 😂. This chair is very obviously smaller than her previous chair, it’s also significantly cheaper in price and build, it’s also not as durable feeling or stable, and it’s just not as padded. Yet somehow it’s an amazing chair that we both like better than her previous chair??? Like it’s crazy that this chair somehow works better in so many ways. Her desk is modified to be shorter than normal desks (again, she small lol) and her previous chair was just too big. The wheels are also like SUPER smooth, like you can run a chair race easily with it. It rolls over her rug and tucks into her desk (which is in our bedroom) easily. The amount of space this has save us when the chair isn’t being used is a lot. Previous chair was much bigger and didn’t tuck in at all. The color is nice and the padding is plenty for a small and much lighter than 500lbs woman. I’m 6 feet and 200 lbs and the chair is nice for me as well. My chair is bigger and more secure in the backing, which is similar to this one. The lowest tension setting on my chair is still too high for her to lean back on my chair. This chair has a lower tension minimum and she can easily lean back freely, as well as keep enough tension to work without sagging. This chair is surprisingly outstanding! I’m sure my wife will destroy it quicker than the last one, but it’s so cheap that even if it only lasts 1-3 years, I’ll happily buy it ones or twice more 🤷🏽‍♀️. Maybe by then they’ll invent a comfortable titanium chair that’s affordable that she won’t destroy 😂.
