How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to refresh the earpads on your existing Audio-Technica M-Series headphones for video calls, choose Audio Technica HP-EP Replacement; if you need to repair a broken headband, hinge or cushion on a pair of Beats Studio 3, choose Adhiper Studio3. These two products are not really competitors — one is a wear part for A-T studio cans, the other is a structural repair kit for Beats. The right pick comes down entirely to which headphone you already own and what is actually broken. If your goal is simply the best headset for video calls you can keep using, the answer usually starts with fixing what you have.
• Audio Technica HP-EP Replacement — biggest strength: genuine A-T earpads that fit a long list of M-Series models, so you restore comfort and seal instead of replacing the whole headphone.
• HP-EP Replacement — biggest trade-off: it is only earpads. It does nothing for a cracked headband, a snapped hinge or a broken cable, and it fits Audio-Technica M-Series only.
• Adhiper Studio3 — biggest strength: a multi-part repair kit (hinges, headband, cushion, screws and a screwdriver) that lets you rebuild a Beats Studio 3 instead of retiring it.
• Adhiper Studio3 — biggest trade-off: it is a DIY job. You supply the time and patience, and it is made only for genuine Beats Studio 3 headphones.
• Who HP-EP Replacement is for: ATH-M20x / M30x / M40x / M50x owners whose pads are flattened, peeling or uncomfortable.
• Who Adhiper Studio3 is for: Beats Studio 3 owners with a snapped headband or hinge who want to keep the headphones alive.
This is a first-party replacement part. Audio-Technica makes it, and the compatibility list is unusually broad for a wear item: ATH-M20x, M20xBT, M30x, M40x, M50, M50s, M50x, M50xBT, M50xBT2, M50xSTS and M50xSTS-USB. That matters because the M-Series is one of the most common studio-headphone families in home setups, and the pads are the first thing to go. Foam compresses, the covering flakes, the clamp gets uncomfortable after a long session.
In my opinion, this is the single most useful upgrade you can make to an older pair. Fresh pads restore the seal against your head, which is what makes a closed-back studio headphone sound like itself — thin, leaky pads are the usual reason a trusted pair starts sounding flat and quiet. In practical terms, that is what turns a tired pair of M50x into a genuinely good headset for video calls: you get the isolation back, the mic arm or inline mic you already use still works, and you are not shopping for a whole new product.
Adhiper Studio3: Who It's For
The Adhiper Studio3 is a repair kit, and it is honest about that. You get one pair of replacement hinges, a replacement headband, a rubber foam cushion, four screws and a screwdriver — seven pieces in total. Adhiper states the size, color and construction are close to the OEM spec, which is the whole point: the goal is a headphone that looks and folds like it did before the break.
The obvious use case is the classic Beats Studio 3 failure. The headband and hinge area takes all the stress of folding and unfolding, and when it goes, the headphones are structurally useless even though the drivers are fine. Without a kit like this, that usually means a repair shop or a new pair. Adhiper explicitly frames the product as a way to avoid both — with the honest caveat, printed right in the listing, that you need to spend some time doing the repair yourself.
That caveat is the real decision point. This is not a plug-and-play accessory. You will be unscrewing, prying, aligning and reassembling, and if you are not comfortable with small parts and a screwdriver, the kit will sit in a drawer. It is also strictly for genuine Beats Studio 3 headphones — Adhiper repeats that warning twice, which tells you people have bought it for the wrong model. Color is black and gold, so it will not blend invisibly into every Studio 3 finish. If you own Studio 3s and the frame is broken, this is a sensible, self-service route. If you own anything else, it is not for you.
Side-by-Side: Which Should You Choose?
• Best for a broken headband or hinge → Adhiper Studio3. HP-EP pads cannot help a cracked frame; the Adhiper kit is built exactly for that failure.
• Best for long video-call sessions → Audio Technica HP-EP Replacement. Fresh pads on a closed-back M-Series pair keep outside noise out and your voice consistent, which is what you want on a call.
• Best for a DIY repair project → Adhiper Studio3. It ships with the screws and screwdriver you need, but you bring the time and steady hands.
• Best for a genuine first-party part → Audio Technica HP-EP Replacement. It is made by Audio-Technica for its own headphones, with a listed one-year warranty.
• Best for a multi-part kit → Adhiper Studio3. Hinges, headband and cushion in one box, so you are not chasing individual pieces.
• Best for the widest model compatibility → Audio Technica HP-EP Replacement. Eleven M-Series models are listed, including the Bluetooth and STS variants.
• Best fit check before buying → both. HP-EP is for Audio-Technica M-Series only; Adhiper Studio3 is for genuine Beats Studio 3 only. Getting this wrong is the main way either purchase disappoints.
If I had to pick one for a video-call setup, I would buy the Audio Technica HP-EP Replacement. In my opinion it is the better value in the everyday sense: a small, first-party part that revives headphones you already trust, restores the seal and comfort, and keeps your call setup exactly as it is. The Adhiper Studio3 is the smarter buy only in one specific situation — you own Beats Studio 3 headphones with a broken headband or hinge and you are willing to do the repair yourself. Match the part to the headphone you actually own, and you will not regret either one. Whichever you land on, check the current price on Amazon before you commit.
how to connect studio headphones
On wired M-Series models you plug the cable into the earcup jack and the other end into your computer, interface or phone — no pairing involved. Bluetooth variants like the ATH-M50xBT2 pair wirelessly instead. If you are replacing pads with the HP-EP, the connection does not change at all; you are only swapping the cushions.
how to test studio headphones
Play a familiar track and listen for even output on both sides, then check that the pads seal evenly against your head — an uneven seal is the most common cause of a channel sounding weak. On a repaired Beats Studio 3, test the folding action and hinge tension first, since that is the part the Adhiper kit replaces.
how to bluetooth studio headphones
Only the Bluetooth models in the M-Series list — the ATH-M20xBT, M50xBT, M50xBT2 and M50xSTS — pair wirelessly. Put them in pairing mode and select them from your device's Bluetooth menu. The HP-EP earpads have no electronics, so they never affect pairing.
how to pair beats studio headphones
Put the Studio 3 into pairing mode and select it from your phone or laptop's Bluetooth list. If you have just rebuilt them with the Adhiper Studio3 kit, confirm the hinge and headband are fully seated and the earcup connections are intact before pairing, since a loose assembly can interrupt the electronics.
