How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to turn almost any headset into part of your streaming look, choose Razer Kitty Ears V2; if you need to bring a worn-out pair of Soundcore Space Q45 headphones back to life, choose AHG Accessory House Global Cool Gel Space.
• Razer Kitty Ears V2 — biggest strength: a 26 g clip-on silicone accessory with adjustable, retractable straps that fasten around almost any headset band, so you change your look without changing your gear.
• Razer Kitty Ears V2 — biggest trade-off: it's purely cosmetic. There's no audio function here, and it's built for adult users who want the animal theme, not for someone fixing a broken headphone.
• AHG Accessory House Global Cool Gel Space — biggest strength: a pair of replacement ear pads built specifically for the Soundcore Space Q45, using cooling gel, breathable mesh and extra-thick high-density memory foam.
• AHG Accessory House Global Cool Gel Space — biggest trade-off: it only fits one headphone model. If you don't own Space Q45s, it does nothing for you.
• Pick Razer Kitty Ears V2 if you already like your headset and want to personalize it for streaming, photos or just for fun.
• Pick AHG Accessory House Global Cool Gel Space if your Space Q45 pads are peeling, flattened or uncomfortable and you want the comfort and seal back.
The Razer Kitty Ears V2 is an accessory, and it's honest about that. You get one pair of clip-on kitty ears in the Quartz colorway, made from premium silicone, weighing just 26 g. They attach with adjustable, retractable straps that can be fastened around any part of your headset band, so the fit isn't locked to one brand or one model. The enclosure is silicone, the carrying case is black gas-phase silicone rubber, and the ears themselves are a triangle shape in the brand's animal theme.
What it does best is change the personality of a headset you already own. If you stream, record, or just spend a lot of time on camera, the ears are a fast visual upgrade that doesn't require buying new audio gear. Razer also states the V2 is 50 percent larger than the previous version for a bigger visual boost, and the silicone is waterproof and dustproof, which matters if your desk is a snack zone or your setup lives near a window.
Who should skip it? Anyone shopping for sound. There's no noise control, no driver, no battery — nothing that changes how your headphones perform. It's also aimed at adults, so it's not a kids' toy. If you want a cleaner, more understated look, this isn't the product for you. But if the whole point is a cute stream persona, the clip-on design and adjustable straps make it one of the more flexible options out there, because it isn't tied to a single headset.
This one solves a very specific, very common problem. Pads wear out. They flatten, they peel, they stop sealing properly, and suddenly your noise isolation isn't what it used to be. The AHG Cool Gel Space pads are replacement ear cushions made for the Anker Soundcore Space Q45, sold as a two-count set, and they're built to reverse exactly that decline. The materials are the story: cooling gel, a breathable mesh liner, extra-thick high-density memory foam, and protein leather on the sides. The color is black, and the enclosure combines all four of those materials.
The design intent is clear. The mesh liner and gel are there to cut heat buildup during long sessions. The high-density foam is there to give you back the pressure-free, supportive feel and a better seal, which in turn helps the noise isolation your Q45s were bought for. The construction is seam-stitched and heat-sealed, which the brand says is meant to stop splitting and extend how long the pads last. Installation is done by hand with a video guide referenced on the insert in the box, and there's a one-year warranty listed.
Who should buy it? Space Q45 owners whose pads are cracking, crumbling or just uncomfortable. Who should skip it? Everyone else. This is not a universal pad, and it's not a cosmetic upgrade for a different brand. If your Q45s are fine, you don't need it. If they're not, it's a targeted fix rather than a replacement headphone.
• Best for personalizing an existing headset → Razer Kitty Ears V2. Universal clip-on fit, adjustable straps, no model lock-in.
• Best for restoring comfort on a specific headphone → AHG Cool Gel Space. It's made for the Soundcore Space Q45 and nothing else.
• Best for streaming and on-camera presence → Razer Kitty Ears V2. It's a visual product, and that's the whole point.
• Best for hot ears and long listening sessions → AHG Cool Gel Space. Cooling gel plus a breathable mesh liner is aimed squarely at heat buildup.
• Best for light weight → Razer Kitty Ears V2. At 26 g it adds almost nothing to your headset; the AHG pad set is listed at 70 g total.
• Best for durability-minded buyers → AHG Cool Gel Space. Seam-stitched, heat-sealed construction and a one-year warranty.
• Best for a quick, tool-free change → Razer Kitty Ears V2. Snap on, adjust the straps, done.
• Best for a repair rather than an upgrade → AHG Cool Gel Space. It replaces worn parts instead of decorating working ones.
My Verdict
There's no fixed definition, but the term generally describes headphones built with higher-grade materials, better padding and more attention to comfort and isolation than budget models. In practice, a big part of that premium feel comes from the pads — the foam density, the surface material and the seal they create. That's exactly the layer the AHG Cool Gel Space pads replace on the Soundcore Space Q45, using cooling gel, breathable mesh, high-density memory foam and protein leather.
That depends on what you value, and I won't pretend one model wins for everyone. What I can say is that the parts you touch every day matter as much as the drivers. If your current headphones already sound good but feel tired, upgrading the cushions — like the AHG set for the Space Q45 — is often the smarter move than replacing the whole headphone. If you're happy with the sound and just want a different look, an accessory like the Razer Kitty Ears V2 does that job without touching the audio.
Pairing is standard across the category: put the headphones into pairing mode, open your device's Bluetooth settings, select the headphone from the list and confirm. Active noise cancelling is then toggled separately, usually with a button or app control on the headset itself. Note that neither product here is a headphone — the Razer Kitty Ears V2 is a clip-on accessory and the AHG Cool Gel Space is a set of replacement ear pads for the Soundcore Space Q45.
Again, this is subjective, and I'd rather be honest than crown a winner. The most premium-feeling headphones tend to be the ones with materials that hold up over years — dense foam, quality leather, sturdy stitching — because those are what keep comfort and isolation intact. That's the logic behind the AHG pads, which are seam-stitched and heat-sealed to resist splitting. If you want to compare current options and prices, check the latest price on Amazon before deciding.
