Introducing the all-new HiBy x FAudio Project Ace, a high-performance single dynamic driver IEM developed by HiBy and FAudio. The pair comes equipped with a 12mm large-sized dynamic driver unit with a Mg-Li Alloy dome and a Beryllium-plated diaphragm. The pair has three-chamber air-pressure management, CNC-machined Aluminum Alloy ear shells, and a unique design shape as well. Both HiBy and FAudio have worked together to finely tune the tuning of Project Ace for excellent dynamic response and rich tone. We are super excited for Project Ace, we want to explore what HiBy and FAudio have done with a 12mm large-sized dynamic driver unit here.

Two Prominent Names With Unmatched Passion For Hi-Res Audio:-

HiBy and FAudio are two of the prominent names in the HiFi Audio industry. From 2011, HiBy has been focusing primarily on the R&D of high-end digital audio playback and product development. FAudio has been pursuing the craftsmanship of high-end earphones since 2015. Both brands have years of expertise under their names and have a huge fan following. For the latest Project Ace, both HiBy and FAudio have researched together to develop a single dynamic driver set with cutting-edge technologies, promising high-end sound at a more affordable price point!!

Powerful Sound With A Large Dynamic Driver:-

The HiBy x FAudio Project Ace houses a large 12mm dynamic driver unit. While most products in the market today feature an 8 or 10mm dynamic driver unit, the large 12mm unit on the Project Ace promises accurate high-frequency timbre and rich low and midrange details. This driver houses a Beryllium-plated diaphragm which is lightweight and extremely fast. It has a new Mg and Li alloy dome structure, which has greatly improved the efficiency of the driver.

Strong Magnetic Design:-

The Project Ace combines the strengths of the Magnesium-alloy dome and Beryllium-plated diaphragm with an exclusively designed high-power magnetic circuit. This not only enhances the efficiency of the pair but also reduces the Total Harmonic Distortion effectively as well.

Enhanced Air Pressure Management With T.B.A.C:-

The Project Ace has an enhanced airflow management system based on FAudip’s patented T.B.A.C(Triple Built-in Acoustic Chamber) technology. The internal structure of the chamber has been designed in such a way that the air flow is efficient and has no fit or vacuum issues for the users. This results in smoother, cleaner, output with natural playback effects.

Solid and Lightweight Build:-

Project Ace Ear Shells are light in weight and have a unique shape to them. The shape has been ergonomically designed for a comfortable wearing experience while the entire shell is made up of high-quality T6063 series aluminium alloy material. They are carved using a high-precision CNC machining process. The set offers great comfort while listening to your favourite melodies.

Litz Type 5 High-Purity Stock Cable:-

HiBy bundles the Project Ace with a Litz Type5 coaxial braided cable with copper and silver-plated copper wire cores. the cable has an eight-core design and features a swappable termination plug system as well. The cable comes with 3.5mm and 4.4mm swappable plugs in the package.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back. Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.

Actually Cooling Pillow
Size: Queen (1 Count), Color: Original White (Cooling)
This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.
