If you want a drop-in refresh for a pair of Beats Solo 2 or Solo 3 Wireless that keeps the original on-ear look and feel, choose Adhiper Earpad Replacement; if you need replacement pads for a newer pair of Beats Solo 4 and want a distinctive Cloud Pink finish with a guided install, choose SOULWIT Earpads.
• Adhiper Earpad Replacement — biggest strength: protein leather plus memory foam, with a mounting tool and pre-applied adhesive included, so a tired Solo 2 or Solo 3 gets a fresh cushion surface without guesswork.
• Adhiper Earpad Replacement — biggest trade-off: it will not fit Solo 4, Solo HD, Solo Pro, or any Beats Studio over-ear model, so it only helps a narrow slice of owners.
• SOULWIT Earpads — biggest strength: high-grade protein leather over high-density foam aimed squarely at the Solo 4, with a detailed user guide rather than a tool.
• SOULWIT Earpads — biggest trade-off: it is a single-model product — Solo 4 only — and the brand states it will not fit Studio over-ear, Solo HD, Solo 2 or Solo 3.
• Buy Adhiper if you own Solo 2 or Solo 3 Wireless and want a straightforward cushion replacement with a removal tool in the box.
• Buy SOULWIT if you own a Solo 4 (MUW23LL/A) and want a softer pink aesthetic with manufacturer guidance through the swap.
The Adhiper set exists to solve one specific problem: worn-out pads on a Beats Solo 2 or Solo 3 Wireless. That is literally the whole brief. The listing is blunt about it — the pads fit Solo 2 and Solo 3 only, and the brand explicitly warns buyers that "studio" on the side of a pair of headphones means these will not work, and that the ear cups on a Studio model are physically larger than a Solo's cushions. If your cans say Solo and Wireless, you're in the right place. If they say Studio, you're not.
The build is artificial protein leather over memory foam. In practice that combination is what gives an on-ear pad its two most important traits: a smooth, skin-friendly surface that doesn't grab and drag, and a foam core that compresses and springs back rather than going flat after a few weeks. Adhiper also claims the material is water-resistant and anti-vermin, and there's a thin dust mesh over the driver opening to keep debris out of the ear cup. That's a small detail, but it's the sort of thing that matters on a headphone you throw in a bag.
Installation is the part that separates this from a bare-bones pad set. You get two ear pads plus a small installation base tool. The process is: pop the old pads off with the tool, clean off any leftover tape residue, peel the backing off the new pads' adhesive, line them up on the left and right cups, press firmly, then double-check the seating. The brand mentions 3M VHB adhesive film specifically, which is the same class of tape used in a lot of OEM assembly — it holds, and it's not supposed to be repositioned repeatedly.
Who should buy it: Solo 2 and Solo 3 Wireless owners whose pads are peeling, cracked, or flattened, especially anyone who wants the tool included rather than improvising with a fingernail. Who should skip it: Solo 4 owners, anyone with Solo HD, Solo Pro, or any Beats Studio over-ear model, and anyone with a wired Solo 2 (the fit list is the wireless versions).
SOULWIT's pads are aimed at the newest Solo generation. The fit list is one model: Beats Solo 4 Wireless, part number MUW23LL/A. The brand puts that in capitals and warns twice — once in the title, once in the bullet list — that these do not fit Studio over-ear headphones or the older Solo HD, Solo 2 and Solo 3. That's a manufacturer being refreshingly direct instead of padding a compatibility list to catch more searches.
The construction story is high-grade protein leather with high-density foam. High-density foam is the meaningful phrase here: a denser core resists the slow compression that makes old pads feel mushy, and it's what lets a pad seal properly around the ear. SOULWIT says the seal delivers excellent noise isolation and comfort, which is the honest mechanical outcome of a well-fitting, denser cushion — less gap between pad and head means less outside noise leaking in and less bass leaking out. The brand also makes the fair point that worn pads hurt sound quality, and that new pads are a cheaper way to restore a headphone than replacing the headphone.
Where SOULWIT differs from Adhiper in the box is the install kit. There's no removal tool mentioned — instead you get a detailed user guide walking you through the swap. If you're comfortable working with your hands and just want clear instructions, that's fine. If you'd rather have a physical pry tool in the package, Adhiper is the more hands-on-ready option.
The finish is Cloud Pink, which is a real design choice rather than a neutral black replacement. If you bought the Solo 4 partly for how it looks, this keeps that energy going.
Who should buy it: owners of a Beats Solo 4 Wireless who want new cushions, especially anyone who wants a pop of color and step-by-step guidance. Who should skip it: everyone else — Studio over-ear owners, Solo HD, Solo 2 and Solo 3 owners, and anyone who wants a black or neutral pad.
• Best for Beats Solo 2 or Solo 3 Wireless → Adhiper Earpad Replacement (explicitly listed as compatible).
• Best for Beats Solo 4 Wireless → SOULWIT Earpads (the only model they fit).
• Best for Beats Studio over-ear headphones → neither. Adhiper says no to Studio 2/3, and SOULWIT says no to Studio over-ear. Look for a pad set built for Studio specifically.
• Best if you want a removal tool included → Adhiper, which ships two pads plus an installation base tool.
• Best if you want a written walkthrough instead → SOULWIT, which includes a detailed user guide.
• Best for a distinctive color → SOULWIT in Cloud Pink; Adhiper comes in a dark purple protein leather.
• Best for foam that holds its shape → SOULWIT's high-density foam is the more compression-resistant spec on paper; Adhiper's memory foam is the softer, more rebound-focused option.
• Best for keeping dust off the driver → Adhiper, which adds a thin dust-proof mesh over the ear opening.
• Best for a wider model spread → Adhiper, since it covers two Solo generations instead of one.
In my opinion, this comes down to which Beats you actually own, because these two products barely overlap. If you have Solo 2 or Solo 3 Wireless, I'd buy the Adhiper Earpad Replacement — it's the one that fits, it comes with the tool, and the memory foam plus protein leather is exactly what a tired on-ear pad needs. If you have a Solo 4, I'd buy the SOULWIT Earpads — high-density foam, a guided install, and a color that actually looks like a deliberate choice. Neither one is a Studio over-ear pad, so if that's your headphone, keep looking.
how to wear over ear headphones
Over-ear headphones sit with the pads surrounding your ears rather than pressing on them, with the headband resting on the crown of your head. On-ear models like the Beats Solo line work differently — the pads press against the ear itself. That's why pad thickness and foam density matter so much on a Solo: a flattened pad changes both the fit and the seal. Both Adhiper and SOULWIT pads are for on-ear Solo models, not over-ear Studio models.
how do over ear headphones work
A driver inside each ear cup pushes air to create sound, and the pad forms the seal between the cup and your head. A good seal keeps outside noise out and keeps low frequencies from escaping, which is why worn or cracked pads make a headphone sound thin. SOULWIT's high-density foam and Adhiper's memory foam both target that seal — Adhiper adds a dust mesh over the opening, SOULWIT emphasizes noise isolation from the denser core.
are studio headphones worth it
That depends on what you need, and it's a separate question from these pads. What matters here is a hard compatibility fact: Adhiper's pads fit Solo 2 and Solo 3 Wireless only, and the brand warns that headphones marked "studio" are not compatible because Studio ear cups are larger than Solo cushions. SOULWIT states plainly that its pads do not fit Studio over-ear headphones. If you own a Studio, neither of these is your replacement.
what headphones do professional studios use
Studios generally reach for over-ear models with large cups and a full seal around the ear — that's the "studio over-ear" category, and it's exactly the category both of these pads are not built for. Adhiper is for Solo 2 and Solo 3 Wireless; SOULWIT is for Solo 4 Wireless. Both are on-ear pads. If you want to refresh a Studio over-ear headphone, you need a pad designed for that cup size.
