If you want a wired, in-ear fit that is designed to reduce surrounding noise for calls, choose Asixxsix IEM Headphone; if you need wireless open-ear listening that keeps you aware of your surroundings, choose Vestamore AI Voice Open. For calls, my choice is Asixxsix if passive isolation matters most, while Vestamore suits people who value a cable-free fit and environmental awareness.
• Asixxsix’s biggest strength: an in-ear fit with three silicone tip sizes and a cable that wraps around the ear; trade-off: it is wired, not wireless.
• Vestamore’s biggest strength: open-ear wireless listening with earhooks and a charging case; trade-off: its stated listening time is 4–6 hours per charge.
• Asixxsix is the more focused pick for a snug fit and reduced ambient noise; Vestamore is the more practical pick for outdoor activity and hearing what is happening nearby.
• Choose Asixxsix if you want a wired listening setup and an in-ear seal. Choose Vestamore if you want wireless convenience and an open-ear design.
• Neither sheet specifies a dedicated call microphone or call-quality feature, so I would not choose either on the assumption of superior voice pickup.
The Asixxsix is a wired in-ear monitor with a single balanced armature unit, a detachable cable, and three sizes of silicone tips. Its wrap-around cable design is intended to help keep the earpieces secure. The resin housings add a distinctive look, but the practical point is the combination of an in-ear fit and replaceable cable connection.
That setup makes sense for someone who wants a closer, more isolated listening experience while staying seated at a desk, rehearsing, or listening in a noisy setting. The product describes noise cancellation, but the sheet does not specify active noise-canceling electronics. I would treat the snug in-ear fit as the relevant design feature, rather than assume it works like electronic noise cancellation.

Vestamore AI Voice Open: Who It's For
Vestamore takes the opposite approach. Its open-ear earbuds use flexible earhooks to stay in place without sealing the ear canal. That can suit walking, cycling, or workouts where hearing nearby activity matters. Wireless 5.4 connectivity is listed with a stated range of 33–49 feet, and a 500 mAh case provides additional power beyond the 4–6 hours of listening cited for a single charge.
The open construction is both the product’s main appeal and its key trade-off. You can remain more aware of your surroundings, but it is not the design I would choose when the priority is blocking outside sound. The sheet also describes a waterproof build for sweat, rain, and splashes, but it does not give a specific water-resistance rating, so I would not infer a particular level of protection.
For calls, Vestamore may appeal if you want to move around without a cable and prefer not to cover or plug your ears. Still, the supplied details do not state microphone specifications or call-noise processing. Its “AI Voice” name is not enough on its own to establish how clearly it handles calls. Think of it as an open-ear wireless listening option, not a guaranteed call-quality upgrade.
• Best for a wired in-ear fit → Asixxsix IEM Headphone. It has silicone tips in S, M, and L, plus a pre-shaped wrap-around cable.
• Best for awareness outdoors → Vestamore AI Voice Open. Its open-ear construction is designed to let surrounding sound remain part of the experience.
• Best for wireless listening → Vestamore AI Voice Open. It uses Wireless 5.4 and includes a charging case.
• Best if you want a detachable cable → Asixxsix IEM Headphone. Its cable detaches, though the sheet does not describe a wireless mode.
• Best for longer continuous listening without a stated recharge break → Asixxsix, with a caveat. It has no battery requirement listed; Vestamore specifies 4–6 hours per charge. That does not establish anything about comfort over a long session.
• Best for workouts in changing weather → Vestamore AI Voice Open. Its materials and design are described as waterproof and suited to sweat, rain, and splashes, though no specific rating is provided.
• Best for a sleep-headphone-style use case → neither is an obvious match. Asixxsix sits in the ear and has a cable; Vestamore’s earhooks are designed for a secure fit during activity. Neither sheet describes a sleep-specific shape.
• Best for calls when you need a proven microphone setup → neither can be confirmed from the listed details. If choosing between them anyway, pick Asixxsix for its more isolating in-ear design, or Vestamore for wireless movement and awareness.
The distinction between these two is not simply wired versus wireless. It is whether you want to close off more of the outside world or leave it audible. That matters during a walk, in a shared office, or while listening in a noisy place. It also matters on calls: an open fit may help you stay aware, while a snug in-ear fit is more suited to listening with less surrounding sound. Neither product sheet confirms call microphone performance, so I would keep that limitation in view.
My Verdict
I would choose Asixxsix for calls if I wanted a wired in-ear fit and less surrounding sound competing for attention.
I would choose Vestamore if wireless movement and outdoor awareness mattered more than isolation.
My overall call-focused recommendation is Asixxsix, based on its in-ear design and three tip sizes—not on any stated microphone advantage.
Neither product’s details confirm call-specific audio features, so I would verify those before treating either as a dedicated headset.
The sheets do not specify microphone hardware or call-noise processing for either product. Asixxsix has an in-ear fit that may suit listening in distracting surroundings; Vestamore offers wireless use and an open fit for awareness.
Its open-ear design is intended to let you hear your surroundings, so it is not the natural choice for blocking ambient sound. The product description mentions active noise cancellation in its title, but the feature details provided do not explain how it works with the open-ear design.
The stated listening time is 4–6 hours per charge. The 500 mAh case adds extra power, but the sheet does not state the total number of hours available with the case.
Asixxsix is described as wired and has a detachable cable. Vestamore is wireless and includes a digital cable, but the listed details do not identify its connector as USB-C.
