If you want to bring a pair of tired, comfortable over-ear headphones back to life with plusher pads and better isolation, choose BRAINWAVZ XL Micro Suede; if you need a cheap, no-fuss wired USB-C earbud for a phone or tablet that has no headphone jack, choose ACANDYA USB C Earbuds.
• BRAINWAVZ XL Micro Suede — biggest strength: a memory foam, micro suede replacement pad designed as a comfort and isolation upgrade for a long list of large round-cup headphones.
• BRAINWAVZ XL Micro Suede — biggest trade-off: it isn't a product you use on its own — you need a compatible headphone to fit it to, and fitment depends on your cup and mounting system.
• ACANDYA USB C Earbuds — biggest strength: a wired USB-C in-ear with an inline mic, volume/button control, a built-in DAC chip and three sizes of silicone tips, aimed at phones and tablets without a 3.5mm port.
• ACANDYA USB C Earbuds — biggest trade-off: sound quality and comfort live or die by the silicone tip seal, and there's no wireless freedom — it's a cable, all the time.
• Who each pick is for: BRAINWAVZ for tinkerers and long-session listeners who already own big over-ear cans; ACANDYA for anyone who just wants a simple wired set for calls and music on a USB-C device.
The BRAINWAVZ XL Micro Suede is a replacement earpad, not a headphone. That single fact defines everything about it. It's built around a layer of high-grade memory foam wrapped in a super-soft micro suede material, and the pitch is straightforward: softer, thicker-feeling comfort than the stock pads on a lot of headphones, plus better isolation and longer pad life thanks to that foam core. The pads measure roughly 4.33 x 1.18 x 4.33 inches and use a large mounting flap on the rear so they can be stretched onto a wide range of round-cup mounting systems.
The compatibility list is where this thing earns its keep. BRAINWAVZ lists it for a long spread of large over-ear models — AKG (K550, K551, K553, K612, K702-family, Q701, K712, K7XX and more), Audio-Technica (ATH-R70X, ATH-AD700X, ATH-AD1000X, ATH-AD2000X and others), Beyerdynamic DT770/DT880/DT990, HiFiMan HE4XX and HE-560, plus Monoprice, Samson, Superlux, Pioneer, JVC, HyperX and more. If your headphones are on that list and the stock pads are flat, flaking or just uncomfortable after an hour, this is a genuinely sensible swap.
Who should buy it? Someone who already owns a pair of big over-ear headphones they like the sound of, but can't stand wearing for long sessions anymore. The micro suede surface is the softest material BRAINWAVZ offers in this line, and memory foam is the right call for people who want the pad to hold its shape rather than collapse.
Who should skip it? Anyone who doesn't own a compatible headphone — obviously — and anyone who wants a plug-and-play product with zero fiddling. Fitting replacement pads takes a little patience, and if your cups are oval or use an unusual mount, the universal flap may not seat cleanly. It's also worth being honest that "better than stock" is the manufacturer's framing, and in my opinion it's a fair ambition for a pad upgrade, but it isn't a guarantee for every headphone on that list.
The ACANDYA USB C Earbuds are the opposite kind of product: a complete, ready-to-use wired earphone with a USB-C plug on the end. There's no 3.5mm jack here, which is exactly the point — this is for the phone, tablet or laptop that dropped the headphone port and left you hunting for a dongle. The compatibility list reads like a who's-who of recent USB-C devices: iPhone 15/16/17 families, Samsung Galaxy S21 through S26 plus the A-series, Google Pixel 5 through 10, OnePlus, iPad 10, iPad Air and iPad Pro, and Motorola Edge and Razr models.
Inside is a dynamic driver rated at 32 ohm, and ACANDYA builds in a DAC chip, which is the part that matters most on a digital-only connection — it's what converts the USB-C signal into something the drivers can actually play, and it's why this kind of earbud can sound noticeably fuller than a cheap adapter setup. The brand also claims strong sound isolation and clear call quality, and the inline module handles volume, track skipping and answering or rejecting calls through a push-button control. A built-in microphone means you can take calls without reaching for the phone.
The fit story is where the thought went in. You get three sizes of ultra-soft silicone tips — small, medium and large — and the ergonomic bud shape is designed to stay put and reduce fatigue over long wear. That S/M/L spread genuinely matters, because small ears, kids and a lot of women get a poor seal from one-size buds, and a poor seal is what kills both comfort and bass. The package also includes an earphone clip and a protective case.
Who should buy it? Anyone who wants a cheap, simple wired set for a USB-C phone or tablet, especially if they take a lot of calls or have struggled to get earbuds to stay in. Who should skip it? Anyone who wants wireless freedom, or who cares about sound isolation at a level only active noise cancellation can deliver — this is passive isolation from the tip seal, which is a real but limited thing. And if your device still has a headphone jack, you're paying for a connector you don't need.
• Best for reviving headphones you already own → BRAINWAVZ XL Micro Suede. It's an upgrade part, not a new headphone.
• Best for plug-and-play simplicity → ACANDYA USB C Earbuds. In the box, into the port, done.
• Best for long listening sessions on big over-ears → BRAINWAVZ XL Micro Suede. Memory foam plus micro suede is built for extended wear.
• Best for calls and inline control → ACANDYA USB C Earbuds. Microphone, volume and a multifunction button on the cable.
• Best for a device with no 3.5mm jack → ACANDYA USB C Earbuds. That's literally the design brief.
• Best for people with hard-to-fit ears → ACANDYA USB C Earbuds. Three silicone tip sizes versus one fixed pad size.
• Best for isolation on over-ear headphones → BRAINWAVZ XL Micro Suede. The thicker foam is aimed at a tighter, quieter seal around the ear.
• Best for a low-commitment purchase → ACANDYA USB C Earbuds. It's a complete product with a case, clip and spare tips.
If I had to pick one, I'd pick based on what's already on my desk. For most people walking into this comparison cold, I'd recommend the ACANDYA USB C Earbuds, because it's a complete, self-contained product that works the moment you open it, and the DAC chip, inline mic and three tip sizes cover the everyday basics well. But if you already own a pair of big round-cup headphones from the BRAINWAVZ list and the stock pads have gone flat, I'd choose the BRAINWAVZ XL Micro Suede instead — in my opinion that's the upgrade that changes your daily experience the most, because comfort is what keeps you wearing a headphone. Check the current price on Amazon before you commit, since both sit in very different budget brackets.
FAQ
They work with USB-C iPhones — the 15, 16 and 17 families are listed. Older Lightning-port iPhones aren't, so check your port before buying.
Different jobs. The ACANDYA relies on a silicone tip seal for passive sound isolation, while the BRAINWAVZ pad uses thicker memory foam to improve isolation around a full-size ear cup. Neither offers active noise cancellation.
That's a specific design goal — three tip sizes (S/M/L) are included, and the brand calls out fit for children, women and smaller ears, which is more flexibility than a one-size bud gives you.
