If you want premium call clarity with a secure in-ear fit for active multitasking, choose Technics Hi-Fi True; if you need marathon battery life and deep noise isolation for long listening sessions, choose 1MORE Over Ear.
• Technics Hi-Fi True: Best-in-class voice pickup with eight microphones and JustMyVoice technology, but the smaller form factor means less physical isolation from wind or traffic.
• 1MORE Over Ear: Unbeatable 100-hour playtime and massive 40mm drivers for studio-grade sound, though the over-ear design is bulkier for gym use or tight headsets.
• Who is this for?: The Technics pick suits professionals who take frequent calls on the go; the 1MORE option fits travelers and audiophiles who prioritize endurance and immersion.
The Technics Premium Hi-Fi True Wireless Bluetooth Earbuds are engineered for people who refuse to compromise on audio fidelity while demanding absolute professionalism during conversations. The standout feature here is the advanced calling architecture. With eight high-sensitivity MEMS microphones and their proprietary JustMyVoice technology, these earbuds are built to ensure your voice comes through without the usual background clutter. This isn't just about hearing you better; it is about preventing the frustration of being misunderstood during critical moments. If your daily routine involves taking conference calls from a busy street, a noisy coffee shop, or a bustling office, the enhanced noise reduction in the microphone array is the primary reason to reach for these.
Beyond the call quality, the audio experience is designed for purists who demand reference-quality sound. The unit houses a masterfully crafted 10mm free-edge dynamic driver within a unique acoustic structure. This setup pushes the boundaries of what wireless earbuds can do, delivering depth and texture that rivals wired setups. The inclusion of LDAC compatibility allows for state-of-the-art Bluetooth transmission, carrying approximately three times the data of conventional codecs. This matters if you listen to high-resolution music files and want to hear the nuances of a recording exactly as the artist intended, rather than a compressed approximation.

However, this level of performance comes with specific usage constraints. These are in-ear buds that rely on a concha fit foam seal to function correctly. If you cannot achieve a snug twist-and-fit seal, the noise cancellation and acoustic performance will degrade significantly. They are ideal for users who value a secure, comfortable fit that stays put during movement, such as on a golf course or at the gym, but they require a bit more attention to earbud placement than simple drop-in solutions. Furthermore, the battery life is respectable but modest compared to over-ear competitors; you get seven hours of continuous use with noise cancelling on, extending to 24 hours total with the charging case. For someone who needs to listen all day without ever touching a charger, the need to pop them back into the Qi-compatible wireless charging case might be a necessary interruption.
The 1MORE Over Ear Bluetooth Headphones are a powerhouse for anyone whose primary concern is endurance and immersive soundscaping. The defining characteristic of this device is its staggering battery capacity. With up to 100 hours of standard playtime and 65 hours when Active Noise Cancellation is engaged, these headphones eliminate the anxiety of running out of power mid-session. A quick five-minute charge unlocks ten extra hours of listening, which makes them exceptionally practical for long-haul flights, cross-country road trips, or marathon workdays where charging outlets are scarce. If you have ever arrived at an airport only to realize your headphones are dead, the sheer longevity of this model solves that problem permanently.
Sound quality is another pillar of this product, driven by precision-tuned 40mm diamond-like drivers that push the frequency range up to 40kHz. This hardware supports dual Hi-Res Audio certification and utilizes LDAC technology to deliver rich, studio-grade audio. The sound has been tuned by Grammy-winning engineer Luca Bignardi, ensuring a natural, balanced profile that captures every sonic detail from deep bass to crisp highs. For the listener who treats music as a primary activity rather than background noise, the larger driver size offers a physical presence and air movement that smaller earbuds simply cannot replicate. The QuietMax ANC system also blocks over 45dB of external noise, making it perfect for subways, airports, and other environments where silence is a luxury.
The trade-off lies in the form factor and portability. As over-ear headphones, they utilize soft protein leather cushions and an adjustable fit designed for comfort during long wear. While this makes them excellent for home listening, office work, or travel relaxation, they are inherently bulkier than true wireless earbuds. They may not feel as "secure" during high-intensity physical activities like running or intense gym workouts compared to the in-ear stability of the Technics. Additionally, while they support wired mode, the reliance on Bluetooth 5.4 and wireless connectivity means you must keep an eye on the charge cycle if you plan to use them constantly, even if that cycle is incredibly long. They are best suited for stationary listening or travel where the user does not mind the slightly larger footprint of the ear cups.
• Best for calls in noisy environments → Technics Hi-Fi True: The eight-mic array and JustMyVoice technology provide superior voice isolation for professional communication.
• Best for battery life → 1MORE Over Ear: With 100 hours of playtime, it dwarfs the competition and removes the need for frequent charging.
• Best for high-resolution audio fidelity → Tie (but different approaches): Both support LDAC, but Technics uses a 10mm dynamic driver for compact clarity, while 1MORE uses 40mm drivers for expansive soundstage.
• Best for active mobility and sports → Technics Hi-Fi True: The secure in-ear foam fit and lack of dangling wires make them safer and more stable for movement.
• Best for long-haul travel and commuting → 1MORE Over Ear: The 45dB+ noise cancellation and plush ear cushions offer a sanctuary of silence on planes or trains.
• Best for wireless convenience and minimalism → Technics Hi-Fi True: The Qi-compatible charging case keeps desks clutter-free and the earbuds pocketable.
• Best for deep bass and immersion → 1MORE Over Ear: The larger drivers physically move more air, creating a fuller, richer low-end response.
• Best for quick top-ups → 1MORE Over Ear: A mere five-minute charge provides ten hours of playback, whereas the earbuds require full case insertion for recharging.
I would buy the Technics Hi-Fi True for my daily workflow because I spend a significant portion of my time on calls and value the ability to communicate clearly without distraction. The eight-microphone setup and JustMyVoice technology address a specific pain point—being heard perfectly—that most headphones ignore in favor of just playing music. While the 1MORE headphones are incredible machines for pure listening endurance, the versatility of the Technics earbuds in handling both high-fidelity audio and professional-grade voice transmission makes them the more useful tool for a modern, connected lifestyle. If your priority is staying sharp and connected during the workday, the Technics solution is the one to get.
No, neither of these models are "open ear." The Technics are in-ear buds with active noise cancellation, while the 1MORE are closed-back over-ear headphones. However, the Technics model is arguably the best in-ear option for calls due to its specialized microphone array.
The 1MORE Over Ear headphones block more physical noise due to their 45dB+ QuietMax ANC and sealed over-ear design, making them superior for blocking out subway rumble or airplane engines compared to the in-ear Technics model.
Yes, both units support voice control. The Technics earbuds allow you to switch modes and control settings via the Technics Audio Connect app and voice commands, while the 1MORE headphones include AI-powered noise reduction and mic technology to assist with clear calls and interactions.
Both are designed for extended use, but the 1MORE Over Ear headphones are likely more comfortable for very long sessions (8+ hours) due to the plush protein leather cushions and lighter pressure distribution on the head compared to the in-ear seal required by the Technics.
