If you want convenient wireless listening for audiophiles, choose Supersonic IQ Sound IQ-243TWS; if you need a wired in-ear monitor with a detachable cable, choose Asixxsix IEM Headphone. The Supersonic is the more practical pick for workouts and everyday phone use, while the Asixxsix puts its emphasis on a secure fit and noise-blocking in-ear design.
Neither is a traditional over-ear headphone, and the data does not establish either as a definitive audiophile sound winner. The choice is really between wireless convenience and a wired IEM setup.
• Supersonic IQ Sound IQ-243TWS strength: Bluetooth 5.3, touch controls, an LED power display, and up to 8 hours of average battery life. Trade-off: It depends on battery power and has no wired listening option.
• Asixxsix IEM Headphone strength: A detachable cable, three silicone tip sizes, and an around-ear cable design. Trade-off: It is wired, so it does not offer the freedom of true wireless earbuds.
• Supersonic is for: Listeners who want pocketable earbuds for calls, daily commutes, and workouts where water-splash resistance matters.
• Asixxsix is for: Listeners who prefer an in-ear monitor fit, want a removable cable, and prioritize passive isolation for focused listening.
The Supersonic IQ Sound IQ-243TWS is built around convenience. These are in-ear true wireless earbuds with Bluetooth 5.3, touch controls, and a charging case with an LED power display. The display gives you a quick way to check the case’s power status, while the earbuds’ in-ear sensors pause audio when you remove them and resume it when you put them back.
For everyday phone use, the feature mix is straightforward. Dual microphones support hands-free calls, and voice access to Google Assistant and Siri is available. The stated average battery life is 8 hours, with a listed charging time of 20 hours; that charging-time figure is worth checking carefully against the product details before buying, since the sheet does not clarify its exact meaning. There is no headphone jack, so wired listening is not an option.

The audio details include a dynamic driver and a listed frequency range of 20 Hz to 20 kHz. Those figures describe the stated hardware and range, but they do not prove that these earbuds deliver a particular tonal balance or outperform a wired IEM. Choose the Supersonic for wireless convenience, calls, touch controls, and splash resistance. Skip it if you specifically want a detachable cable, different silicone tip sizes, or a wired monitor-style setup.
The Asixxsix IEM Headphone is a wired in-ear monitor with a detachable cable. Its defining design choices are the around-ear cable fit, three included silicone ear-tip sizes—small, medium, and large—and a resin cavity. That combination is aimed at listeners who want an in-ear fit they can adjust and a cable that can be removed rather than permanently attached.
The product description specifies a single balanced armature unit and describes its sound as HiFi with full-range effects. It also claims noise cancellation, but the provided details do not explain a measurement method or identify active electronic noise cancellation. I would read this as a focus on blocking surrounding sound through the in-ear design, not as evidence that it has the same kind of active noise-control system described for some wireless headphones.
This model makes more sense for focused listening, music practice, or situations where a cable is acceptable. The around-ear routing is intended to help keep the fit secure, and the three tip sizes give you options for finding a comfortable seal. Those traits may also help when listening in noisier surroundings, but the data does not provide a quantified isolation level.
The trade-off is practical: this is not a true wireless earbud, and there is no stated battery life or Bluetooth connection. The connectivity field says “ethernet,” which does not fit the wired-earphone description; it should not be taken as a useful confirmation of a phone connector type. If you are looking for the best over-ear headphones for audiophiles, neither product matches that form factor. The Asixxsix is an in-ear monitor, not an over-ear headphone.
Side-by-Side: Which Should You Choose?
• Best for true wireless listening → Supersonic IQ Sound IQ-243TWS. It connects over Bluetooth 5.3 and does not use a cable between the earbuds and your device.
• Best for checking case power at a glance → Supersonic IQ Sound IQ-243TWS. Its charging case has an LED power display.
• Best for choosing among tip sizes → Asixxsix IEM Headphone. It includes small, medium, and large silicone tips.
• Best for splash resistance during exercise → Supersonic IQ Sound IQ-243TWS. Its IPX4 rating covers water splashes, though it does not establish protection against submersion.
• Best for hands-free calls and voice assistant access → Supersonic IQ Sound IQ-243TWS. It has dual microphones, touch controls, and access to Google Assistant and Siri.
• Best for an around-ear cable fit → Asixxsix IEM Headphone. The pre-molded cable routing is designed to wrap around the ear and help secure the fit.
• Best for listeners who want specified battery life → Supersonic IQ Sound IQ-243TWS. The listed average life is 8 hours; the Asixxsix is wired and has no battery-life figure.
I would choose the Supersonic IQ Sound IQ-243TWS for audiophiles who value easy wireless use, calls, and splash resistance more than a wired monitor setup. Its features make it the more versatile everyday option, especially for phone listening and workouts. I would pick the Asixxsix instead if a detachable cable, multiple tip sizes, and an around-ear fit are the priorities. Neither sheet gives enough evidence to declare a sound-quality winner.
