If you want studio-grade fidelity and a wired connection for critical listening, choose Hidizs MK12; if you need active noise cancellation, wireless freedom, and superior call clarity for daily commutes, choose 1MORE Over Ear.
• Hidizs MK12: Delivers exceptional sound detail with its 12mm magnesium driver and Hi-Res certification, but requires a wired connection and offers no active noise cancellation.
• 1MORE Over Ear: Provides massive battery life, effective QuietMax ANC, and AI-powered mic technology for calls, though it is a bulkier over-ear design compared to in-ear monitors.
• Who it's for: The MK12 suits audiophiles who prioritize raw audio quality and portability above all else, while the 1MORE model fits professionals and travelers who need isolation and hands-free communication.
The Hidizs MK12 Turris is built for the listener who refuses to compromise on the purity of their audio signal. This isn't a gadget designed to hide behind features like Bluetooth or noise cancellation; it is a dedicated tool for high-fidelity music reproduction. The core of its performance lies in the 12mm diaphragm made from 91% pure magnesium, paired with a powerful 1.5T magnet system. This combination creates a frequency response that stretches from 10Hz to 45kHz, capturing nuances that standard consumer gear often misses. If you are an enthusiast who listens to complex orchestral pieces, intricate classical arrangements, or high-resolution rock tracks, this unit provides the sonic canvas you need.
Its construction speaks to durability and precision. The enclosure utilizes aluminum alloy metal cavities, which likely contribute to a rigid structure that minimizes unwanted resonance. Inside, you will find silver-plated twisted pair wire cables crafted from high-purity oxygen-free copper. This specific wiring choice is crucial because it ensures low resistance and high conductivity, allowing the electrical signal to reach your ears without degradation. The product comes with three pairs of tuning filters—Bass, Vocal, and Balanced—which allow you to physically alter the sound signature to match your preference or the genre you are currently playing. Whether you are commuting, sitting at your office desk, or enjoying time outdoors, the MK12 relies on its ability to deliver studio-grade sound directly through a 3.5mm jack or a compatible dongle DAC.

However, this focus on fidelity means you must accept certain trade-offs. The MK12 is an in-ear monitor, not a pair of over-ear headphones. While the silicone ear tips provide passive sound isolation, they do not offer the same level of active environmental blocking as modern noise-canceling tech. Furthermore, the reliance on a wired connection means you are tethered to your source device unless you use a separate Bluetooth transmitter. There is no battery inside the earbuds themselves to manage, which eliminates charging anxiety but also removes any convenience of wireless movement. This product is ideal for someone who values the direct connection between their digital file and their eardrum more than the freedom of untethered motion. It is the choice for the person who wants to hear every breath taken by the singer and every pluck of the guitar string, provided they are willing to carry a cable.
In stark contrast to the wired, in-ear nature of the MK12, the 1MORE Over Ear model is engineered for the modern professional who lives a mobile, connected life. Its primary strength lies in its ability to create a private listening environment anywhere you go, thanks to the QuietMax Active Noise Cancellation system. This technology actively blocks up to 45dB of external noise, making it exceptionally effective in chaotic environments like busy subways, noisy airports, or bustling city streets. If your day involves frequent travel or working in open offices where background chatter is constant, this feature alone transforms the listening experience from a distraction into a sanctuary.
The design philosophy here centers on comfort and long-term usability. These are over-ear headphones featuring soft protein leather cushions and an adjustable fit, specifically engineered to be worn for extended periods without fatigue. You can wear them through long work sessions, across multi-hour flights, or during relaxation at home without the pressure points often associated with cheaper headsets. The physical build includes a carrying case, suggesting that portability and protection are key considerations for the user. Inside, the audio engine is driven by 40mm diamond-like drivers that support a frequency range up to 40kHz, ensuring a balanced sound profile that remains clear even at higher volumes. The inclusion of LDAC technology further enhances this, delivering three times the data of standard Bluetooth connections for a richer, more detailed wireless audio stream.
Perhaps the most compelling reason to choose this model is its utility for communication. In a world where conference calls and voice chats are routine, the 1MORE Over Ear integrates AI-powered noise reduction and advanced microphone technology. This setup ensures your voice cuts through ambient noise, delivering crisp, clear calls even when you are in a loud environment. The battery life supports this heavy usage pattern with an impressive average playtime of 100 hours, or 65 hours if you keep the active noise cancellation enabled. A quick five-minute charge unlocks ten extra hours of use, meaning you rarely have to plan your day around a charging station. This product is perfect for anyone who needs a reliable, comfortable, and smart headset that handles both high-quality music and professional communication without missing a beat.
• Best for Calls: The 1MORE Over Ear wins decisively due to its dedicated AI-powered noise reduction and advanced mic array, whereas the MK12 lacks any active call optimization features.
• Best for Battery Life: The 1MORE Over Ear offers up to 100 hours of playback on a single charge, eliminating the need for constant power management, unlike the fully passive MK12 which draws power from the source.
• Best for Sound Isolation: The 1MORE Over Ear uses active QuietMax ANC to block 45dB+ of noise, providing a much quieter experience than the passive isolation of the Hidizs MK12 in-ears.
• Best for Audio Fidelity: The Hidizs MK12 leverages a 12mm magnesium driver and Hi-Res certification to potentially offer a more direct, uncolored sound signature for critical listening.
• Best for Portability: The Hidizs MK12 is significantly lighter and smaller, fitting easily into a pocket, while the 1MORE Over Ear requires the included carrying case for transport.
• Best for Wireless Freedom: The 1MORE Over Ear connects via Bluetooth 5.4, offering true wireless mobility, while the MK12 is strictly a wired solution requiring a 3.5mm or 4.4mm connection.
• Best for Customization: The Hidizs MK12 allows you to swap physical tuning filters (Bass, Vocal, Balanced) to change the sound profile, a feature the 1MORE does not offer.
• Best for Long Sessions: The 1MORE Over Ear’s soft protein leather cushions and over-ear design are generally better suited for all-day wear compared to the in-ear form factor of the MK12.
For my own setup, I would choose the 1MORE Over Ear. While the Hidizs MK12 is undeniably a marvel of engineering for music purists, the reality of modern life demands a device that handles the chaos of our environment. The 1MORE model solves the two biggest pain points of daily audio consumption: distracting background noise and unreliable call quality. Its ability to isolate you from a noisy subway while maintaining crystal-clear audio and handling conference calls with AI assistance makes it the far more practical tool for general use. If you are looking for the best open ear headphones for calls, the 1MORE delivers a level of professionalism and comfort that the wired in-ear option simply cannot match. It is the smarter investment for anyone who needs their audio gear to work as hard as they do.
While "open ear" typically refers to bone conduction or open-back designs, the 1MORE Over Ear is a closed-back, over-ear model specifically tuned for clear calls. It uses AI noise reduction to ensure your voice is heard clearly, making it a top contender for professional communication, though it is not technically an "open" style.
The 1MORE Over Ear boasts an impressive average battery life of 100 hours with quick charging capabilities, whereas the Hidizs MK12 has no internal battery since it is a fully passive, wired device that draws power directly from your source player.
The 1MORE Over Ear is the superior choice for a busy office because it features QuietMax Active Noise Cancellation that blocks significant external noise, while the Hidizs MK12 relies solely on passive isolation from the ear tips.
