If you want lightweight, over-ear wired headphones for monitoring and DJ use, choose Sennheiser HD 25; if you need in-ear monitors with two sound profiles and replaceable MMCX connectors, choose Generic Sonicast PRO Reference. For glasses wearers, the key difference is where each product sits: the HD 25 surrounds the ears, while the Sonicast sits in them.
I’d lean toward the HD 25 for someone who specifically wants an over-ear headphone, and toward Sonicast for a compact, wired in-ear setup with selectable tuning. Neither product sheet gives a glasses-specific fit measurement, so comfort will depend on your ears, frames, and personal fit.
• Sennheiser HD 25 strength: Lightweight, wired over-ear design intended for monitoring, recording, and DJing. Trade-off: It is not an in-ear option, and the listed setup is wired.
• Generic Sonicast PRO Reference strength: In-ear design with SL and DL sound profiles, plus replaceable MMCX connectors. Trade-off: Its over-ear cable routing and in-ear fit may not suit someone who prefers a conventional over-ear headphone.
• Pick the HD 25 if you want an over-ear monitoring headphone and value its adjustable ear-cup and headband joint.
• Pick the Sonicast if you want wired in-ear monitors with a choice between a clarity-focused profile and a bassier one.
• For glasses wearers: Consider the Sonicast if you want to avoid an over-ear headband-and-cup arrangement; consider the HD 25 if over-ear listening is your preference and you are comfortable assessing the fit with your frames.
The HD 25 is an adult-oriented, wired over-ear headphone designed for monitoring, recording, DJing, and similar listening tasks. Its dynamic drivers are listed with a 16 Hz–22,000 Hz frequency range. That specification describes the stated range, not a guarantee that every listener will hear every frequency equally. The practical appeal here is the straightforward headphone format: place the cups over your ears, connect the cable, and use it for a listening or monitoring setup.
The product description also calls out a revised mechanical joint where the ear cups meet the headband, intended to make adjustment smoother and the connection more solid. That matters if you want to reposition the cups rather than leave them fixed in one place. The package listing includes a headphone holder with a padded cradle and adjustable angle, along with a 10-foot extension cable. Those extras may be useful for a desk or studio setup, though they do not change the headphone’s core wired design. The listed headphone jack is 6.35 mm.

For glasses wearers, the HD 25 is worth considering if you want over-ear headphones and are willing to judge how the ear cups meet your frames. The supplied information does not specify clamping force, pad material beyond foam, or glasses-specific comfort, so I would not assume that its lightweight design alone guarantees a comfortable fit. Its listed noise control is sound isolation, but no numerical isolation figure is provided.
Generic Sonicast PRO Reference: Who It's For
The Sonicast PRO Reference is a wired in-ear monitor with an over-ear cable design and MMCX connectors. Its two listed sound profiles give it a more adjustable listening approach than the HD 25’s single described setup: SL is aimed at clarity and spatial balance, while DL adds more low-frequency energy and warmth. That gives a listener a choice between a more clarity-oriented presentation and a fuller, bass-focused one, based on the product description.
The product sheet identifies a 4th-generation SF-DRIVER and a bass-tuning chamber intended to refine sub-bass performance. It also says the driver can produce higher acoustic output than the previous generation. That comparison is specifically against an earlier generation; it does not establish a direct loudness or fidelity advantage over the HD 25. The included ORZA tips and soft twist cable are part of the described in-ear setup, while the replaceable MMCX connectors offer a way to replace the cable connection rather than treating it as permanently fixed.
For someone comparing the best bluetooth headphones for glasses wearers, there is an important distinction: this Sonicast is wired, not Bluetooth. Its in-ear placement may be appealing if you want to avoid over-ear cups around glasses, but it still routes the cable over the ears, and the sheet does not promise that this arrangement will suit every frame or ear shape. It is also not the open ear earbuds for glasses wearers option: it is an in-ear monitor, not an open-ear design.
• Best fit for an over-ear preference → Sennheiser HD 25. Its listed placement is over the ear, and its design is described for monitoring, recording, and DJing.
• Best fit for in-ear listening → Generic Sonicast PRO Reference. It sits in the ear and uses an over-ear cable arrangement.
• Best for choosing between two sound profiles → Sonicast. SL is described as clarity- and spatial-balance oriented; DL emphasizes more low-frequency energy and warmth.
• Best for a listed 6.35 mm headphone connection → HD 25. The data identifies that jack, as well as a 10-foot extension cable in the package description.
• Best for replaceable MMCX connectors → Sonicast. Its connectors are identified as replaceable, giving the cable connection a serviceable design feature.
• Best for glasses wearers who want to avoid over-ear cups → Sonicast may be the better fit to consider. It is an in-ear monitor, though its over-ear cable routing still needs to work with your frames.
• Best for monitoring and DJ use explicitly named in the product details → HD 25. Those are among its stated applications.
• Best for a desk setup with a headphone holder included → HD 25. The package description includes an adjustable-angle holder with a padded cradle.
My Verdict
I would choose the Sennheiser HD 25 if I wanted an over-ear headphone for wired monitoring or DJ use, especially with the listed extension cable and holder for a fixed setup. I’d choose the Sonicast instead if in-ear placement, two tuning profiles, and replaceable MMCX connectors mattered more.
For glasses wearers, my recommendation is to start with the form factor you actually want: in-ear Sonicast to avoid over-ear cups, or HD 25 if you prefer a conventional over-ear headphone and can confirm the fit works for your frames.
Next, think about how you listen. The HD 25 is presented for monitoring, recording, and DJing, and its package listing includes a 10-foot extension cable and a holder. Those details point toward a stationary or work-focused setup. The Sonicast is also wired, but its two profiles give you a described choice in tuning. If you want to switch between a clarity-oriented presentation and a warmer, bass-heavier one, that flexibility is a meaningful distinction.
Connection details deserve a check before buying. The HD 25 listing identifies a 6.35 mm jack, while the Sonicast is described as a 3.5 mm wired earphone. Make sure the connection matches the device or setup you intend to use; do not assume an adapter is included unless the listing says so. The HD 25 package description also mentions an extension cable, but that is not the same as changing the headphone’s basic connection.
Finally, keep expectations tied to what is actually specified. The Sonicast’s driver-generation comparison is relative to its predecessor, not a direct test against the HD 25. The HD 25’s frequency range is a stated specification, not a complete description of tonal balance. If total cost matters to your decision, check the current price on Amazon using the page’s button rather than relying on an old figure.
The Sonicast’s in-ear placement avoids putting over-ear cups around the frames, but its cable routes over the ears. The HD 25 is over-ear. Neither product sheet provides a glasses-specific fit guarantee, so comfort depends on your frames and fit.
zIs the Sonicast PRO Reference Bluetooth?
No. It is described as a wired in-ear monitor. The HD 25 is also listed as wired, so neither of these two options is a Bluetooth headphone.
The Sonicast’s DL profile is described as adding low-frequency energy and warmth, and its bass-tuning chamber is intended to refine sub-bass. The available information does not provide a direct measured comparison with the HD 25, so that description should not be treated as a head-to-head test result.
