If you want a wireless in-ear monitoring setup with automatic pairing and more than 50 meters of stated transmission distance, choose Devilclaw Ear Monitor System; if you need wired on-ear headphones, choose P PUPGSIS Over Ear Professional. For glasses wearers, the key difference is whether an in-ear wireless system or a wired on-ear design better suits the way you listen.
Devilclaw Ear Monitor System vs P PUPGSIS Over Ear Professional at a Glance
• P PUPGSIS’s biggest strength: a straightforward wired, on-ear headphone design. Trade-off: the available specifications do not state its cable details, driver information, battery requirements, or frequency range.
• Choose Devilclaw for instrument monitoring, rehearsals, and performance situations where a wireless connection matters.
• Choose P PUPGSIS if you specifically want wired on-ear headphones and do not need a wireless transmitter-receiver system.
Devilclaw is a wireless in-ear monitor system built around a transmitter and receiver. The devices pair automatically, so the stated setup is simple: power them on and connect the system rather than manually pairing each unit. Its UHF wireless connection has a stated transmission distance of over 50 meters, which may suit practice or performance spaces where a cable between the audio source and listener would be inconvenient.
For instrument players, the built-in high-sensitivity condenser microphone is described as capturing an instrument’s sound. The system is presented for studio use, guitar, DJ work, live performance, concerts, and individual or group practice. It also lists uses with voice amplifiers and speaker systems, and names brass instruments such as trumpet, horn, and trombone. Twelve channel banks offer options for monitoring, though the product information explicitly says one transmitter does not support multiple receivers. That matters if several musicians need to listen through separate receivers: this system is not described as a one-transmitter-to-many-receivers solution.
The in-ear fit may make sense for someone who wants to keep the earcups of conventional headphones off the head, including some glasses wearers. But fit is personal, and the supplied specifications do not explain the shape or comfort of the in-ear tips beyond describing them as rounded. The built-in battery is listed for over eight hours of use once fully charged, with an eight-hour charge time also specified. That makes charging part of the routine, rather than an afterthought.

Who should skip it: Skip Devilclaw if you want wired on-ear headphones, need more than one receiver per transmitter, or do not want an in-ear fit and rechargeable equipment.
P PUPGSIS is a wired, on-ear headphone model. Its simplest appeal is the connection type: it does not rely on the wireless transmitter-and-receiver arrangement used by Devilclaw. That makes it the more direct choice for a listener who specifically wants wired headphones for monitoring or listening and is comfortable staying connected by cable.
For glasses wearers, the on-ear design deserves a closer look. The headphones sit on the ears rather than inside them, but the available product details do not say how much pressure the ear pads apply or how they interact with glasses arms. Some listeners may prefer an on-ear style to in-ear tips; others may find that anything pressing around the ears is less comfortable with glasses. The listed information does not settle that question, so the fit preference should guide the choice rather than an assumption that one style will suit everyone.
The product is identified as the M20 and includes a user manual. It has a one-year manufacturer warranty listed. The supplied details identify it as wired and on-ear, but do not provide a cable length, connector type, driver size, frequency range, or battery information. The title refers to a 1/4-to-3.5mm audio jack and 40 kHz Hi-Res, but without further supporting specifications in the product information here, I would not use those details to infer sound quality or device compatibility. Check the connection required by your equipment before choosing it.
Who should skip it: Skip P PUPGSIS if you need wireless movement, automatic transmitter-receiver pairing, or a stated long-range monitoring link.
• Best for wireless instrument monitoring → Devilclaw Ear Monitor System. Its UHF connection links a transmitter and receiver without requiring a headphone cable running between the audio source and listener.
• Best for a wired listening setup → P PUPGSIS Over Ear Professional. It is explicitly listed as wired and on-ear, though the supplied details do not specify its cable length or connector.
• Best for a stated transmission distance → Devilclaw Ear Monitor System. Its stated range is over 50 meters. Treat that as the product’s stated figure, not a guarantee for every room or performance space.
• Best for automatic setup → Devilclaw Ear Monitor System. The transmitter and receiver are described as pairing automatically, with no manual input required.
• Best for avoiding in-ear tips → P PUPGSIS Over Ear Professional. Its on-ear placement avoids an in-ear fit, although the fit around glasses arms will depend on the wearer.
• Best for a listed battery runtime → Devilclaw Ear Monitor System. It specifies over eight hours of battery life once fully charged, along with an eight-hour charge time. P PUPGSIS is wired, and no battery is listed.
• Best for individual or group practice features → Devilclaw Ear Monitor System. Its twelve channel banks are intended for use with multiple instruments, but one transmitter is not supported for multiple receivers.
• Best for choosing by documented warranty → P PUPGSIS Over Ear Professional. It lists a one-year manufacturer warranty; Devilclaw’s listed warranty is 90 days.
Buying Considerations
Start with how you plan to connect. Devilclaw is a complete wireless monitoring arrangement with a transmitter and receiver, automatic pairing, and UHF connectivity. That is useful when a cable between the source and your listening position would get in the way. P PUPGSIS is wired, so your setup depends on a compatible connection and a cable. The information provided does not specify cable length or connection details, so confirm those before deciding whether it will work with your equipment.
Battery needs separate thought from connection type. Devilclaw lists over eight hours of battery life and an eight-hour charge time. If you use it regularly, charging is part of the setup. P PUPGSIS is wired, with no battery information listed, so it avoids reliance on a built-in battery as described—but it also cannot offer the wireless freedom listed for Devilclaw. Shoppers searching for the “best long battery life bluetooth earbuds for glasses wearers” should note that Devilclaw is described as a UHF wireless in-ear monitor system, not a Bluetooth earbud. The specifications do not identify Bluetooth connectivity.
Finally, do not assume the products are interchangeable just because both are for listening. Devilclaw is specifically presented as an instrument-monitoring system, while P PUPGSIS is a wired on-ear headphone model. The available information gives Devilclaw a stated range, channel banks, and battery figures, but gives little technical audio detail for P PUPGSIS. If you are looking for the “best rechargeable over ear headphones for glasses wearers,” P PUPGSIS is not described as rechargeable or over-ear; it is listed as wired and on-ear. Check the current product information for the connection and fit details that matter to your setup.
I would choose Devilclaw for instrument monitoring because its automatic pairing, stated transmission distance, and over-eight-hour battery figure make its wireless purpose clear. For glasses wearers, I’d favor its in-ear layout if keeping on-ear pressure away from the frames matters more than avoiding in-ear tips. I would choose P PUPGSIS instead if I specifically wanted wired on-ear headphones. My overall pick is Devilclaw, but only for someone whose needs match a wireless monitor system—not a general-purpose Bluetooth headphone.
