• BRAINWAVZ biggest strength: Purpose-built for the Sony MDR-7506, MDR-V6 and MDR-CD900ST, with a fully perforated protein PU leather cover over memory foam for airflow.
• BRAINWAVZ biggest trade-off: It's a single pair aimed at a specific ear-cup shape, so "universal" fit still depends on your headphone's mounting system.
• TL HONGPHUC 3M biggest strength: A four-pack of memory-foam pads made for 3M WorkTunes Connect and AM/FM radio earmuffs, so you can refresh several headsets or keep spares on hand.
• TL HONGPHUC 3M biggest trade-off: It's a generic replacement pad, not an OEM 3M part, and the listing scatters its compatibility wording across work, mowing and shooting scenarios.
• For whom: BRAINWAVZ for home listeners and studio users restoring Sony MDR cans; TL HONGPHUC for people who live in 3M WorkTunes hearing protection at work or on the mower.
The BRAINWAVZ Perforated Replacement Earpads exist for one clear job: bringing a tired pair of Sony MDR-7506, MDR-V6 or MDR-CD900ST headphones back to life. The pad is built around a small-oval shape with a large mounting flap at the rear, which is what lets it slip onto those classic Sony cups and, per the listing, a range of other on-ear headphones that match the dimensions. The cover is protein PU leather, and the whole surface is perforated — a design choice aimed at airflow rather than total isolation.
Inside sits memory foam. That matters more than it sounds, because memory foam is what keeps a pad from collapsing into a flat disc after months of daily wear. The perforated cover is the more interesting decision: holes across the pad trade a bit of sound sealing for breathability, which usually means less heat build-up and less of that clammy feeling during long mixing sessions or marathon listening. BRAINWAVZ frames it as insulating the ear with a "perfect fit" while letting air move, and that's a reasonable read of the design.
Who should buy it? Anyone with worn, flaking or flattened Sony MDR pads who wants a drop-in refresh without replacing the headphone itself. Studio users, podcasters, and anyone who wears the MDR-7506 for hours at a stretch are the natural audience. Who should skip it? If your headphones aren't an on-ear design with a compatible cup and mounting flap, this isn't the pad for you — check the dimensions (roughly 3.94 x 0.79 x 2.95 inches) against your cups before committing. And if you're looking for maximum isolation rather than airflow, a solid — not perforated — pad is the better call. It's also worth noting the pads are sold as a set for one pair of headphones, not a multi-pack.
The TL HONGPHUC 3M pads are a different animal entirely. These are replacement ear pads built for 3M WorkTunes headsets — the Connect model and the AM/FM radio version — which are hearing-protection earmuffs with built-in audio rather than music headphones. The pad itself is memory foam in black, and the pack contains four pads, which is the headline feature here.
That four-count changes the value math. Instead of buying one pair and hoping it lasts, you get enough to re-pad two headsets, or to refresh one and stash spares for the next time the foam flattens. For anyone who wears WorkTunes all day — mowing, running equipment, working a job site, spending time at a range — pad compression is the failure point, so having backups on the shelf is genuinely useful.
The trade-offs are worth being straight about. This is a third-party pad, not a 3M-branded original, so fit and feel will match the WorkTunes mounting system but won't necessarily be identical to what came in the box. The listing also leans on broad language about noise cancelling, Bluetooth and FM radio, but those are features of the headsets the pads fit — the pads themselves are foam cushions. And the warranty is short: 30 days. Who should buy it? WorkTunes owners whose factory pads have gone flat, cracked or sweaty, especially anyone who wants spares. Who should skip it? Anyone with non-3M headphones, or anyone expecting the pads themselves to add noise cancellation they don't already have.
• Best for a specific, known headphone → BRAINWAVZ. It's explicitly designed for the Sony MDR-7506, MDR-V6 and MDR-CD900ST.
• Best for hearing protection gear → TL HONGPHUC 3M. It's made for 3M WorkTunes Connect and AM/FM radio headsets.
• Best for hot, long listening sessions → BRAINWAVZ. The fully perforated cover is built around airflow, not sealing.
• Best for spares and multi-headset households → TL HONGPHUC 3M. Four pads in the pack versus one pair.
• Best for studio and critical listening → BRAINWAVZ. Memory foam plus a controlled on-ear fit suits the MDR's monitoring role.
• Best for job-site and lawn-mowing use → TL HONGPHUC 3M. The whole context is work, mowing and outdoor noise.
• Best for material clarity → BRAINWAVZ. The listing names both components: protein PU leather cover, memory foam core.
• Best if you're unsure about fit → check your model first, then pick. Neither pad is truly universal; both depend on matching your headphone's cup design.
In my opinion, the BRAINWAVZ Perforated Replacement Earpads are the better buy for most people reading this — but only if you own one of the Sony MDR models they were designed for. The perforated memory-foam design is a purposeful piece of engineering rather than a generic foam disc, and it solves a real problem: hot, flattened pads on a headphone people actually keep for years. The TL HONGPHUC four-pack is the smarter pick if you're re-padding 3M WorkTunes gear, because the quantity and the work-focused fit line up with how those headsets get used. Buy for the headphone you own, not the other way around.
FAQ
They're designed for the Sony MDR-7506, MDR-V6 and MDR-CD900ST. The listing says the large rear mounting flap also lets them fit other on-ear headphones that match the pad dimensions, so measure your cups first.
Four pads. That's enough to re-pad two 3M WorkTunes headsets or keep spares for one. The BRAINWAVZ set, by contrast, is a single pair for one headphone.
No. Those are features of the 3M WorkTunes headsets the pads fit. The pads are memory-foam cushions that restore comfort and fit — the electronics live in the headset.
