• Joghaw Replacement Ear Pads — biggest strength: Custom-fit protein leather and memory foam cushions built specifically for the Sony WH-CH700N, MDR-ZX780 and MDR-ZX770, with tool-free installation and a 180-day warranty.
• Joghaw Replacement Ear Pads — biggest trade-off: It is not a standalone product. Without one of those three Sony headphones, these pads have nothing to attach to, and they add no electronics of their own.
• DIANMO A9 — biggest strength: A complete all-in-one kit — voice changer, sound card, clip-on design, screen, headphones and every adapter you need in the box.
• DIANMO A9 — biggest trade-off: It is a creative effects tool, not a monitoring or listening upgrade; its value depends entirely on whether you want voice effects for gaming, streaming or calls.
• Who each pick is for: Joghaw for Sony WH-CH700N / MDR-ZX780 / MDR-ZX770 owners with worn or flattened pads; DIANMO A9 for gamers, streamers and content creators who want real-time voice effects without buying extra accessories.
Joghaw's ear pads exist to solve one very specific problem: your Sony headphones still work fine, but the cushions have gone flat, cracked or uncomfortable. These pads are made from memory foam wrapped in a thick protein leather (faux leather) enclosure, finished in black, and shaped specifically for the WH-CH700N, MDR-ZX780 and MDR-ZX770. That model-specific fit matters. A generic pad that "sort of" fits changes the seal, and the seal is what gives you bass response and noise isolation in the first place.
The design brief here is comfort plus isolation. The memory foam is meant to keep its shape through long sessions, and the snug fit is what blocks outside noise so you hear more of the music and less of the room. Joghaw also leans into the sound angle directly, describing the pads as improving noise isolation and optimizing bass response. That lines up with how closed-back pads work: a proper seal equals better low-end and less leakage. For anyone doing long mixing sessions, marathon gaming, or DJ practice where the cups sit on your head for hours, that is the whole point.
Installation is the other selling point. Joghaw describes a tool-free process where you peel off the old pads and press the new ones on in seconds, no technical skill required. If you have ever fought with a glued-down ear pad, you know that claim is doing real work.
Who should buy it: anyone who owns a Sony WH-CH700N, MDR-ZX780 or MDR-ZX770 and finds the stock pads worn out, sweaty or painful after an hour. The 180-day warranty adds a bit of confidence for a wear part that takes daily abuse. Who should skip it: anyone without those exact Sony models, and anyone hoping to change how their headphones sound rather than restore them. New pads bring back the fit and isolation you had when the headphones were new — they do not turn a budget pair into a flagship.
The DIANMO A9 is a different animal entirely. It is a voice changer and sound card kit with a color screen, built for gaming, streaming and live content. At roughly 1.97 by 1.97 inches and 39 grams, it is a palm-sized box that clips onto a collar or pocket, which tells you the intended use case immediately: you wear it while you play, talk or stream, and you operate it without looking down.
The headline feature is the voice engine. The A9 offers seven voice-modifying modes — robot, male-to-female, female-to-male, youth, queen, lolita and a childlike mode — and each one gives you ten levels of fine-tuning. That is a lot of range for role-play, prank calls, character work or just keeping your voice anonymous in lobbies. On top of that, three professional sound modes (KTV, recording studio and electric sound) shape reverb and dynamics, which is aimed at karaoke, short-video dubbing and live streaming.
Connectivity is where the A9 earns its keep. It works with Android over Type-C, Apple over Lightning, computers, PS4, PS5 and Xbox One, and it supports plug-and-play over 3.5mm jacks or OTG. DIANMO includes Type-C and Lightning adapters in the box, so switching between a phone, a console and a PC does not require a drawer full of dongles. Inputs cover auxiliary and microphone, output is TRS, and connectivity spans auxiliary and USB. The kit also ships with a charging cable, audio cable, headphones and the adapters — an all-in-one package that is genuinely ready to use out of the box.
Who should buy it: gamers who want voice effects in party chat, streamers and short-video creators adding character voices, karaoke singers, and anyone who takes calls or records voice content and wants a compact, screen-equipped interface. Who should skip it: listeners who just want better-sounding headphones. The A9 is an effects and routing device. If your goal is comfort, isolation or a monitoring upgrade, this is not that product, and the included headphones are a convenience, not a reason to buy.
Side-by-Side: Which Should You Choose?
• Best for restoring headphones you already own → Joghaw Replacement Ear Pads. It only makes sense if you have a WH-CH700N, MDR-ZX780 or MDR-ZX770.
• Best for noise isolation and bass response → Joghaw Replacement Ear Pads. A proper model-specific seal is the mechanism; Joghaw explicitly targets isolation and low-end.
• Best for gaming voice effects → DIANMO A9. Seven voice modes with ten tuning levels each, plus console compatibility for PS4, PS5 and Xbox One.
• Best for streaming and karaoke → DIANMO A9. KTV, recording studio and electric sound modes are built for exactly that.
• Best for plug-and-play across phone, PC and console → DIANMO A9. Type-C and Lightning adapters are included, so nothing extra is required.
• Best for portability → DIANMO A9. At 1.97 inches square and 39 grams with a clip-on mount, it disappears in a pocket.
• Best for a simple, single-purpose fix → Joghaw Replacement Ear Pads. One job, done in seconds, backed by a 180-day warranty.
In my opinion, the right pick comes down to one question: are you fixing gear or adding a capability? If you own a Sony WH-CH700N, MDR-ZX780 or MDR-ZX770 and the pads are flat, cracked or uncomfortable, I would buy the Joghaw Replacement Ear Pads. It is a cheap-feeling fix conceptually but a high-impact one in practice — the seal and comfort come back, and the tool-free install means you are done in seconds. If instead you want voice effects, karaoke modes and a clip-on interface that works across your phone, PC and console, the DIANMO A9 is the more interesting device and the more complete package. I would not buy the A9 to improve listening, and I would not buy the Joghaw pads without the matching Sony model. Match the tool to the job and either one does exactly what it promises. Worth checking the current price on Amazon before you commit, since both compete on value in their own lanes.
can you dj with studio headphones
Yes. Closed-back studio headphones are a common choice for DJ work because a proper seal gives you isolation and stronger bass response, which helps with beatmatching and cueing in loud rooms. That is exactly the property the Joghaw pads are designed to restore on the Sony WH-CH700N, MDR-ZX780 and MDR-ZX770 — worn pads break the seal, and the isolation goes with it. The DIANMO A9 is not a monitoring tool; it is an effects and routing device, so it plays a different role in a DJ setup.
do you need headphones to dj
You need some way to hear the next track privately before the crowd does, and headphones are the standard answer. Most DJ workflows rely on cueing one channel while the other plays out, which requires a sealed, comfortable pair you can wear for hours. That is why pad condition matters more than people expect — memory foam that keeps its shape and a snug fit are what make long sets bearable. If your Sony pads have flattened, replacing them is the more practical move than buying new headphones.
why do djs need headphones
DJs use headphones to preview and cue tracks, beatmatch by ear, and work in noisy environments where the booth monitors alone are not enough. Isolation is the key spec: the better the seal, the less you have to crank the volume, and the clearer the low end is for matching beats. The Joghaw pads target precisely that — noise isolation and optimized bass response on the specific Sony models listed. The DIANMO A9 does not serve this purpose; its strength is real-time voice effects for gaming, streaming and karaoke.
are replacement ear pads worth it compared to buying new headphones
If the drivers and frame are still fine, yes — pads are the part that wears out first, and swapping them restores comfort and isolation without replacing the whole headphone. The Joghaw pads are custom-made for the WH-CH700N, MDR-ZX780 and MDR-ZX770, install without tools, and carry a 180-day warranty. If you want new features rather than restored performance, that is when a different product — something like the DIANMO A9 for voice effects — makes more sense.
