If you want an open-air listening experience with a lightweight honeycomb aluminum casing and self-adjusting support, choose Audio-Technica ATH-AD500X; if you need a removable cable and a lower-impedance design for flexible indoor listening, choose Philips Audio SHP9500. For construction work, though, neither is a wireless or noise-isolating solution: both are open-back, wired headphones that let outside sound in.
My quick verdict: I’d choose the Audio-Technica for its distinctive support system and stated focus on natural sound, while the Philips makes more sense if a removable cable and compatibility with or without a headphone amplifier matter more to you.
• Audio-Technica ATH-AD500X strength: 53 mm drivers, an open-air design, lightweight honeycomb aluminum casing, and self-adjusting 3D Wing Support Housing. Trade-off: wired and open-air, so it is not designed to block surrounding noise or work without a cable.
• Philips Audio SHP9500 strength: 50 mm neodymium drivers, a removable 1.5 m cable, and 32-ohm impedance. Trade-off: also wired and open-back, with no listed noise-control feature.
• Choose the ATH-AD500X if its suspension-style support and open, natural listening design appeal to you.
• Choose the SHP9500 if a removable cable and lower impedance are your priorities for indoor listening.
• For construction work: neither is a multipoint headphone, Bluetooth headphone, or clip-on earbud; neither product sheet lists wireless connectivity or noise isolation.
The ATH-AD500X is an over-ear, wired headphone built around 53 mm dynamic drivers. Audio-Technica describes its open-air design as avoiding a feeling of pressure on the ears, and its honeycomb aluminum casing is identified as lightweight. The self-adjusting 3D Wing Support Housing is the standout fit detail: instead of relying only on a conventional padded headband, it is designed to support the headphones on the head.
That combination makes the ATH-AD500X a reasonable choice for someone who expects to listen in a quiet indoor space and values an open construction, fabric earpads, and a cable connection. Its single-sided cable has an elastic TPE sheath intended to help prevent tangling, and the package includes a 3.5 mm connector with a 6.3 mm adapter. The product sheet also specifies a 48-ohm impedance and a 5–25,000 Hz frequency range.

The Philips Audio SHP9500 is another open-back, over-ear wired headphone, but its details point to a slightly different kind of flexibility. It uses 50 mm neodymium drivers and has a 32-ohm impedance. Philips describes it as suitable for use with or without a headphone amplifier, which may matter if you want to connect it to different indoor audio setups without making an amplifier a requirement.
Its cable is removable and measures 1.5 m, while the included adapter provides a connection from 3.5 mm to 6.3 mm. The double-layer headband cushion and breathable ear cushions are intended to support longer listening sessions. Those details make the SHP9500 a practical fit for someone who wants a wired pair for home or desk listening and values the option to detach the cable.
The same core limitation applies on a construction site: it is open-back, wired, and has no noise-control feature listed. Its product information specifies a 12–35,000 Hz frequency range, but that number does not turn it into a noise-isolating work headset. If you need a Bluetooth connection, multipoint pairing, or a clip-on earbud form for movement around a site, the SHP9500 does not match that brief.
• Best fit if you want self-adjusting support → Audio-Technica ATH-AD500X. Its 3D Wing Support Housing is a specific design feature the Philips sheet does not list.
• Best fit if you want a removable cable → Philips Audio SHP9500. Its 1.5 m cable is removable, while the Audio-Technica cable is described as single-sided and tangle-resistant.
• Best fit if you prioritize an open-air feel → Audio-Technica ATH-AD500X. Its open-air construction is explicitly described as avoiding a sense of pressure on the ears.
• Best fit if you want a lower impedance → Philips Audio SHP9500. It is specified at 32 ohms, compared with 48 ohms for the ATH-AD500X.
• Best fit if you want a slightly larger stated driver size → Audio-Technica ATH-AD500X. Its drivers are 53 mm, compared with 50 mm for the Philips. Driver size alone does not establish which one will sound better to you.
• Best fit if longer-wear cushioning is your focus → Philips Audio SHP9500. Its sheet names a double-layer headband cushion and breathable ear cushions; the Audio-Technica instead highlights flexible raised-fabric earpads.
• Best fit for multipoint headphones for construction work → neither. Multipoint connectivity is not listed for either pair, and both use a wired connection.
• Best fit for Bluetooth headphones for construction work → neither. The listed products are wired; consider a model whose specifications explicitly include Bluetooth if wireless use is essential.
• Best fit for clip-on earbuds for construction work → neither. Both are over-ear headphones, not clip-on earbuds.
• Best fit for a quiet indoor desk or listening area → either, depending on your priorities. Choose the Audio-Technica for its support design and open-air presentation, or the Philips for its removable cable and 32-ohm impedance.
The construction-work question deserves a direct answer. An open-back headphone allows the listening environment to remain part of the experience; it is not the same thing as a protective hearing device, and neither product sheet claims job-site noise protection. If you are comparing options for work near tools or machinery, focus on equipment explicitly designed for that environment rather than assuming either of these headphones will serve that purpose.
The distinction between these two models is more useful in a home office, at a desk, or in another indoor listening spot. The ATH-AD500X puts more emphasis on its open-air feel and support system. The SHP9500 puts useful attention on its detachable cable, cushioned headband, and lower impedance. Both are wired, open designs, so neither is the right answer if your main goal is to shut out surrounding sound or move freely without a cable.
I would buy the Audio-Technica ATH-AD500X for indoor listening because I prefer the appeal of its self-adjusting support and open-air design.
The Philips Audio SHP9500 is the more compelling alternative if a removable cable and 32-ohm impedance better fit your setup.
For construction work, I would choose neither: both are wired open-back headphones, not Bluetooth or multipoint work headsets.
If you need gear for that setting, look for a product specifically suited to the site and its noise conditions.
No. Both are listed as wired headphones. Neither product sheet specifies Bluetooth pairing or multipoint connectivity.
Neither is a clear fit for construction work. Both have open designs and wired connections, and neither sheet lists noise isolation or job-site protection.
Yes. Its included cable is removable and measures 1.5 m. The Audio-Technica sheet describes a single-sided cable with a sheath intended to help prevent tangles, but does not describe it as removable.
Start with your setup and priorities: the ATH-AD500X highlights open-air comfort and self-adjusting support, while the SHP9500 offers a removable cable and 32-ohm impedance. Check the current price on Amazon using the page’s button, then decide whether those features justify it for your use.
