SiP current mode independent amp super driving force
Questyle's exclusive patented "current mode" amplifier technology is what differentiates Questyle hardware from other terminals. As the "engine" of the headphone system, the amplifier has a crucial impact on the improvement of sound quality. Thanks to the self-developed current mode amplifier module, unlike similar products that use op-amp chips for amplification, M12 is not limited by the power of op-amp chips, and has ultra-high current output capability and control power, and the overall load is 0.0003 % ultra-low distortion, fully exploit the potential of headphones.
Smart Impedance Detection
When the earphone is plugged into the M12, the built-in intelligent impedance detection system will automatically detect the earphone impedance and adapt it. For hard-to-drive high-impedance headphones M12 will use the corresponding high level to drive, at this time the Gain (gain) light is red, providing excellent dynamic performance for the headphones. When driving some low-impedance and high-sensitivity earplugs, the output level (gain) light will be reduced according to the actual impedance to turn green (low gain), which is precisely matched and will not over-push, just like a car's automatic shifting.
Questyle Technology and ESS R&D teams in the United States, China, and Canada have spent two years to create a mobile decoding amp that exceeds customer expectations. To commemorate the first cooperation between Questyle and ESS, after the official confirmation, the M12 was marked with the logos of Questyle and ESS. The ESS flagship USB DAC decoder chip ES9281AC selected by M12 can decode up to PCM384kHz/32bit and DSD256. Whether it is the deep bass of the pipe organ in the European cathedral, or the strong bass and guitar melody in the hard rock, it can capture the deep hidden sound. Details in the track.
Support MQA decoding
MQA (Master Quality Authenticated): M12 supports MQA rendering and completes the final expansion of MQA files. When the MQA indicator is magenta, it means that the M12 is rendering the MQA stream or file and is completing the final expansion of the MQA file.
MQA decoding is a new digital encoding format designed to encapsulate very high sample rate audio streams in files small enough to make them suitable for network streaming. The MQA format carries 100% of the information of the original recorded audio signal, then it adapts subtly to the audio product you're using and plays back those signals at the highest quality that playback device can achieve. At this level of playback, you hear the same sound as the artist heard in the studio.
Extremely Compatible
Enjoy high-fidelity fun in a minimalist way
During the development process, Questyle Labs has done a lot of testing and targeted optimization on the compatibility of mainstream mobile phones and tablets and has achieved full compatibility with Android 5.1 and above; for PC-side application scenarios, it supports Windows 10 18.3 and above (driver-free), and Mac OS system.
Technology Black Fashion Silver
The shell of the M12 is made of anodized aluminum sandblasting process, creating two classic colors of technology black and fashionable silver with the matte texture of Questyle's genes, showing a professional atmosphere.

Puppy loves these sticks!
Color: Dogwood & Calming, Size: Medium
Dogs love these sticks! Must smell and taste like real wood because it keeps my puppy from bringing real sticks in the house from outside. She is a heavy chewer and these sticks keep her occupied. We are on our 2nd set.

Our dog loves it but it wasn’t durable enough to last
Color: Dogwood Jack, Size: Large, Color: Dogwood Jack, Size: Large
Our lab took to it as soon as we gave it to her. Perfect size for our 80 lb yellow lab.
However, now that it’s in about 10 days, she’s able to break off chunks from this bone that are dime size or larger, and we have to throw it away

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long.
I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do.
I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.
