If you want hands-free, long-range team communication for small ears, choose Solid Signal Eartec Ultralite PRO16; if you need wired studio-style listening with detachable cables, choose Liquid Audio Audio-Technica ATH-M50X. The key difference is purpose: PRO16 is a wireless intercom system, while ATH-M50X is a pair of wired listening headphones. Neither is a neckband or an IPX7-rated headset, so those labels should not guide this choice.
Solid Signal Eartec Ultralite PRO16 vs Liquid Audio Audio-Technica ATH-M50X at a Glance
• Solid Signal Eartec Ultralite PRO16: Its strength is hands-free, full-duplex communication over a stated range of up to half a mile, with room to expand to 16 users. Its trade-off is that it is built for intercom conversations, not ordinary music listening.
• Liquid Audio Audio-Technica ATH-M50X: Its strength is a wired, closed-back listening setup with 45 mm drivers and three detachable cable options. Its trade-off is that it needs a cable connection and does not provide wireless team communication.
• Choose PRO16 if two or more people need to talk while working, moving, or coordinating at a distance.
• Choose ATH-M50X if your priority is wired audio for studio monitoring, casual listening, or gaming.
• Neither product is a neckband headset, and neither sheet specifies an IPX7 water-resistance rating.
• The PRO16 is a single-ear intercom headset; the ATH-M50X is an over-ear pair of headphones.
The PRO16 is for people who need to keep a conversation going while their hands are busy. It supports full-duplex talk, meaning both people can speak at the same time, and its stated range reaches up to half a mile. The two-headset system can expand to as many as 16 users without a hub or central unit. That makes it a practical design for crews who need continuous coordination rather than a headset for private music listening.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Its single-ear design leaves the other ear open to the surroundings. That can matter when a boat operator needs to hear the engine, a drone operator is working with a spotter, or a coach is coordinating from the sideline. The boom microphone rotates to either side and mutes when flipped up. Battery life is listed at 10 hours, and the batteries can be removed by hand and replaced with a charged one.
I’d consider this set for a small crew that needs to talk across a work area, trail, or outdoor location. It comes with two headsets, two rechargeable batteries, a two-bay charger, a softside case, and cleaning wipes. Skip it if your main goal is music, studio monitoring, or gaming audio from a computer or console: the listed purpose and features center on intercom communication. It also pairs only with other PRO16 headsets, not Eartec UltraLITE Classic or UltraLITE HD systems.
The ATH-M50X is the more conventional listening choice. It is a wired, over-ear headphone with closed-back construction, 45 mm dynamic drivers, and a listed frequency range of 20 Hz to 20,000 Hz. The bundle includes three detachable cables: a short straight option, a longer straight option, and a coiled cable. There is also a 10-foot extension cable, a screw-on quarter-inch adapter, a carrying pouch, and a polishing cloth.
That combination suits someone who expects to plug into listening equipment and wants flexibility in cable length. The swiveling ear cups can turn 90 degrees for one-ear monitoring, while the foldable design helps make the headphones easier to pack. The product information also lists sound isolation. Those features make it a more natural fit for studio-style listening, casual music, and gaming than the PRO16—though the sheet does not specify a microphone or wireless connection.
I would choose it when the job is listening rather than communicating with a crew. The detachable cables are a useful practical detail: you can select among the included lengths instead of being tied to one fixed lead. But anyone who needs hands-free wireless talk between people should look elsewhere. And for shoppers searching for the best hi res neckband headphones for small ears, this is not that category: it is a wired over-ear model, and the provided specifications do not describe it as a neckband or identify high-resolution certification.
• Best for hands-free team conversation → Solid Signal Eartec Ultralite PRO16. It supports simultaneous two-way speech and is designed to expand to 16 users.
• Best for wired music or studio-style listening → Liquid Audio Audio-Technica ATH-M50X. It is a conventional headphone with 45 mm drivers and a stated frequency range of 20 Hz to 20,000 Hz.
• Best for a crew spread across a work area → Solid Signal Eartec Ultralite PRO16. Its stated wireless range is up to half a mile, and the system does not require a hub or central unit.
• Best for cable flexibility → Liquid Audio Audio-Technica ATH-M50X. The bundle includes three detachable headphone cables plus a 10-foot extension.
• Best for keeping one ear open → Solid Signal Eartec Ultralite PRO16. Its single-ear format leaves the other ear available for surrounding sounds.
• Best for one-ear monitoring while listening → Liquid Audio Audio-Technica ATH-M50X. Its ear cups swivel 90 degrees.
• Best for a full workday of intercom use → Solid Signal Eartec Ultralite PRO16. Its listed battery life is 10 hours, and a removable battery can be swapped by hand.
• Best for gaming headphones for small ears → Neither is an obvious fit based on these specs. ATH-M50X is the more relevant listening headphone, but it is over-ear and the sheet does not specify a gaming microphone. PRO16 is designed for intercom use, not game audio.
For fit, the available information is limited. Both products are described as over-ear in the product details, while the PRO16’s feature description emphasizes single-cup wear. Neither sheet gives ear-cup dimensions or claims a fit specifically for small ears. If that fit is your deciding factor, the stated design alone cannot settle it.
The water-resistance question is similarly straightforward. The supplied specifications do not list an IPX7 rating for either model. So a search for IPX7 waterproof on ear headphones for small ears points to a different set of requirements than the products shown here: the PRO16 is a single-ear communication system, and the ATH-M50X is a wired over-ear headphone. Don’t infer waterproofing from either product’s intended use.
My Verdict
For talking with another person or crew, yes: the PRO16 is a wireless full-duplex intercom system with a stated range of up to half a mile. The ATH-M50X is a wired listening headphone, and its supplied details do not describe an intercom function.
The ATH-M50X is the more suitable choice for listening because it is a wired headphone with 45 mm drivers and sound-isolation controls listed in its product details. The sheets do not specify a gaming microphone for it, while the PRO16 is designed around hands-free team communication.
No IPX7 rating is specified for either product in the available information. If water resistance is essential, don’t treat either model as waterproof based on these details alone.
The PRO16 lists 10 hours of battery life and has a removable battery, which is useful for extended intercom work. The ATH-M50X has no battery requirement listed because it is wired; its bundle instead provides several cable lengths for different listening setups.
