Seek Splendid Sound with the latest HiBy RS2 Darwin R2R-based digital audio player. Designed with the evolutionary R2R-based Darwin Architecture, the RS2 packs a natural, lively sound performance in a compact form factor. The player comes loaded with PureAudio version of HiBy OS where users can enjoy their music with proper optimization. HiBy RS2 features dual headphone output ports housing a 3.5mm single-ended and another 4.4mm balanced connection port supporting most new IEMs with ease!!

Purely Designed For Audiophiles:-

Equipped with a PureAudio version of HiByOS, the RS2 gets an optimized operating system ideally designed for system-level audio processing. It provides a clean, pure audio playback pathway, making sure you get the best possible experience for your music.

Evolutionary Darwin Audio Architecture:-

Previously featured on the highly-acclaimed RS6 audio player from HiBy, the RS2 brings the evolutionary Darwin Audio Architecture to your palms. Improving over the traditional R2R ladder array technology, it brings a shot of modern functions such as linearity compensation for the R2R ladder, 256-Tap adjustable FIR filter, Harmonic controller, NOS/OS Switch, etc. It makes the RS2 a fully versatile device that you can use with different IEMs.

256-Tap Adjustable FIR Filter:-

The Darwin Architecture on the RS2 is capable of up to 16x oversampling. You can obviously switch the OS off by using the NOS/OS switch. It consists of a variety of AA filters such as Phase Linearity, High-Fidelity, etc.

NOS/OS Mode Switch:-

Darwin Architecture on the RS2 also features a NOS/OS mode switch. Users can turn the 16x oversampling off anytime by simply selecting the NOS mode.

R2R Ladder Network Linearity Compensation:-

HiBy’s Darwin Architecture comes as a blessing for the traditional R2R ladder DACs. It effectively reduces the distortion caused by the resistance mismatches in an R2R Ladder producing a natural and clean sound presentation.

Powerful Output Stage:-

HiBy has featured a current mode amplification output stage around the R2R array of the RS2. The output stage amplifies the current signal using a powerful OPA1652 OPAMP chip and the Low-Pass Filter consists of two OPA1612 chips. It offers a clean input voltage and powerful output current to the output stage for a dynamic sound performance.

8x MQA Unfolding:-

HiBy RS2 supports 8x MQA unfolding. It provides full MQA signal unfolding support bringing a true high-resolution master-quality authenticated performance for the users!!

Dual MicroSD Card Slots:-

HiBy RS2 has got two microSD card slots each supporting microSD cards up to 2TB capacity. Users can equip the RS2 with two 2TB cards and the device will read them simultaneously.

Long Battery Life:-

HiBy RS2 houses a 3500mAh large rechargeable battery. It provides an extended playback time of up to 10 hours on a single charge. It has up to 40 days of standby.

Loved them so much- Bought another pair
To start off, I have wide feet, ankles, and calves, because i'm a bit on the heavier side. Finding shoes that fit these requirements are difficult. The top part of the shoes that hug my legs are actually still a little roomy. Someone who has slightly larger lower legs can fit into these as well. If you have tiny legs, these shoes may be a little too loose, or if you don't have wide feet. These shoes are literally perfect for my feet and legs. The back unzips so I was able to get my feet into the shoes easily, and even wearing them I didn't feel like my toes were being squished. I ordered a size 10, and it is perfect length and width for my wide feet. Do note: My feet are wide enough to not fit in most shoes, but not too wide, you should pay attention to the measurements if you have wide feet. I was a little skeptical from a review of a woman who had her toes bleeding from these shoes, as I know that is often a problem for me with most shoes I wear. Generally I start bleeding in the back of my heel. So I was skeptical that these shoes would make me bleed. However, I was proven wrong. These are one of the only shoes i've worn that haven't rubbed my skin right off. I believe that has to do with the lovely height of the back, which prevents rubbing on the back of your heels, and the perfect width of the shoes. If your feet are too wide for these shoes, then you will probably bleed, but that's to be expected because the shoe does not fit you and that is often something that can happen with shoes that don't fit. I originally bought the green pair, because I loved the color, but then I loved the fit so much that I bought a second, black pair. These are one of the only shoes with heels I actually wear because they are more comfortable than most, and they're just adorable. I am not generally a high heel wearer, so I'm not used to walking with my heels elevated. Despite that, these shoes were fairly easy to walk in. They are my favorite pairs of heels. and I do highly recommend them. I will be buying more colors in the future, and I hope they will come out with more colors like brown and an aqua/blue shade.

Trying to get what's in picture
Size: 9, Color: Natural Nbpu
Amazon said my size was a 10. So i ordered a 10. Waaaay too long, wide big in general, and I have a wide foot so I was pleasantly surprised. Company did not offer any color in size 9.5 but according to their size guide I "might" fit into a 9! Again, pleasantly surprised that i totally did and even when I put in my "Dr. Scholl's" inserts, i have slight wiggle room for when feet swell. Overall I am happy with the shoe fit, comfortability and height...not that I'd wear these for more than 8 hrs., but comfy enough for a wedding or to wear to work when I have a "mostly office day" instead of out in the yard. HOWEVER... i loved the color and suede-ey look/feel pattern of the size 10. It was exactly as picture/info described. But I'm not sure what happened to the size 9? wth? Although i ORDERED exact same shoe/color but in smaller size...what I got was a much lighter color, and NOT the suede fabric...more nubuck. Bu inside of shoe had same info/tag as the 10. Really hoping that it was a packing/labeling error. Will try one more time to order the 9, in the same 'name' fabric. Fingers crossed that I get what I ordered/want. Otherwise it'll be a return and less stars.
