If you want to bring an aging pair of Skullcandy Grind headphones back to life with fresh memory-foam comfort, choose Xinyuekj Replacement Ear Pads; if you need a complete set of wired USB-C earbuds with a microphone and inline remote for calls and music on a modern phone, choose ZRTXBA USB C Headphones.
• Xinyuekj Replacement Ear Pads — biggest strength: skin-friendly protein leather over high-resilience memory foam, plus an acoustically transparent mesh, that restores comfort, seal and looks to Grind headphones you already own.
• Xinyuekj Replacement Ear Pads — biggest trade-off: it is a repair part, not a product. If you don't own Skullcandy Grind headphones, it does nothing for you, and it's a single pair of cushions with a 90-day warranty.
• ZRTXBA USB C Headphones — biggest strength: a complete plug-and-play USB-C listening kit — two sets of in-ear buds, a built-in DAC, an inline remote with mic, and a 2-year manufacturer warranty.
• ZRTXBA USB C Headphones — biggest trade-off: it's wired, so you're tethered to a 1.2 m cable, and it only works with USB-C devices — no 3.5 mm jack, no Bluetooth.
• Pick Xinyuekj if you already love your Grind headphones and just want them comfortable again.
• Pick ZRTXBA if you need working earbuds for calls, commuting or video meetings on a USB-C phone, tablet or laptop.
This is a focused product with a narrow job. The Xinyuekj ear pads are cut specifically for Skullcandy Grind wired and wireless on-ear headphones, and they're built from two materials that matter for long listening sessions: soft protein leather on the outside and high-resilience memory foam underneath. The over-ear cushioning is designed to reduce heat buildup and pressure against your head, which is exactly the complaint that shows up after a couple of years with worn-out stock pads.
Buy these if you own Skullcandy Grind headphones and the pads are peeling, cracking or flattened. They clip on in minutes with no tools, and you get a black finish that matches the original look. Skip them if you don't have Grind headphones — compatibility is model-specific, so check your headphone model before ordering — or if you're looking for a whole new headset rather than a part. Also note this is a single pair of cushions, and the warranty runs 90 days. For the right owner, though, it's a genuinely sensible way to extend the life of gear you already like.
ZRTXBA USB C Headphones: Who It's For
The ZRTXBA set is a different kind of purchase entirely: it's a two-pack of wired USB-C in-ear headphones, and it's aimed at people whose devices no longer have a headphone jack. Compatibility is the headline here. The listing covers iPhone 17/17 Pro/17 Pro Max, 16 and 15 families, iPad Pro 12.9 and 11-inch, iPad Air 4/5, iPad Mini 6, MacBook and MacBook Pro, the Galaxy S25/S24/S23/S22/S21/S20 line, and a long run of Pixel models from the 9 series back to the 2 XL, plus other USB-C devices. If you've been stuck choosing between charging and listening, that's the problem this solves.
Functionally, it's built around the inline remote. One button handles answer/end calls, reject, play/pause and volume, so you don't have to pull your phone out mid-commute or mid-meeting. The built-in microphone is there for hands-free calls, driving, video conferencing and gaming chat. On the audio side, there's a dynamic driver covering a 20Hz–20,000Hz range and a built-in DAC chip intended to keep high-resolution playback clean — the listing specifically calls out avoiding buzzing, popping and poor contact, with metal-plated connectors to help with that. The cable runs 1.2 metres, which is a reasonable length for a pocket or desk setup.
Buy these if you want a spare-pair situation: you get two complete sets, which is handy for keeping one at home and one in a bag, or splitting them between two people. The passive noise cancellation is seal-based rather than active, so expect modest ambient damping, not silence. Skip them if you still rely on 3.5 mm gear, want wireless freedom, or prefer over-ear cups. The 2-year manufacturer warranty is a real plus for a wired accessory that takes daily abuse.
• Best for reviving headphones you already own → Xinyuekj Replacement Ear Pads. It targets one model and fixes comfort and seal.
• Best for a complete, ready-to-use kit → ZRTXBA USB C Headphones. Two sets of buds, a mic and a remote in one purchase.
• Best for long-session comfort → Xinyuekj Replacement Ear Pads. Memory foam and protein leather are the entire point of the product.
• Best for calls and remote control → ZRTXBA USB C Headphones. The inline remote and high-sensitivity mic are built in.
• Best for device compatibility breadth → ZRTXBA USB C Headphones. iPhones, iPads, MacBooks, Galaxy and Pixel devices are all listed.
• Best for workouts and easy cleaning → Xinyuekj Replacement Ear Pads. Sweat-proof protein leather wipes clean in seconds.
• Best for backup or sharing → ZRTXBA USB C Headphones. The two-pack means a spare always exists.
• Best if you want zero installation → ZRTXBA USB C Headphones. Plug and play beats clipping pads onto a headband.
In my opinion, these two products barely compete — they solve opposite problems, so the right answer depends entirely on what you already own. If you have Skullcandy Grind headphones that are still working but uncomfortable, I'd buy the Xinyuekj Replacement Ear Pads; it's the cheapest way to make good headphones feel new again, and the memory foam and protein leather are exactly the materials I'd want. If you need functioning audio for a USB-C phone, tablet or laptop — especially with a mic for calls — I'd buy the ZRTXBA USB C Headphones instead, mainly for the two-pack value, the inline controls and the longer 2-year warranty. For most readers starting from nothing, ZRTXBA is the more useful purchase.
No. They're designed specifically for Skullcandy Grind wired and wireless on-ear headphones. Check your model before ordering, because fit is model-specific.
Yes. The listing covers iPhone 17, 16 and 15 families, along with iPad Pro, iPad Air, iPad Mini 6, MacBook and many Galaxy and Pixel models. They require a USB-C port, not a 3.5 mm jack.
They're different categories, so compare against your need: Xinyuekj is a single pair of replacement cushions with a 90-day warranty, while ZRTXBA gives you two complete earbud sets with a 2-year manufacturer warranty. Check the current price on Amazon for each before deciding.
The pads use an acoustically transparent mesh over the driver, so the design intent is to preserve the original sound while improving seal and comfort. The thicker foam mainly affects passive noise isolation.
