How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to keep listening to music, podcasts or TV in bed without waking anyone next to you, choose MMUSS Sleep; if you need to block out snoring, traffic or a noisy hotel room, choose GyOnyx 6. They sound like the same kind of product, but they do opposite jobs — one plays sound into your ears, the other keeps sound out.
• MMUSS Sleep — biggest strength: ultra-thin 3 mm speakers that sit flat against your ear, so side sleepers can lie on them without the pressure of a normal earbud.
• MMUSS Sleep — biggest trade-off: it is a wired 3.5 mm replacement speaker set, not a standalone earbud — it is designed to drop into a headband you already own, and it has no noise cancelling.
• GyOnyx 6 — biggest strength: six pairs of moldable silicone plugs that shape to your ear, come in six colours with individual cases, and are fully waterproof.
• GyOnyx 6 — biggest trade-off: they silence the room, not your music — there is no cable, no jack and no audio of any kind.
• Who MMUSS Sleep is for: anyone with a 3.5 mm device and a headband who wants private listening in bed.
• Who GyOnyx 6 is for: anyone who simply wants the room to go quiet — sleepers, swimmers, travellers, concert-goers.
MMUSS Sleep is a clever little problem-solver. Instead of a full pair of earbuds, you get a set of pillow-thin dynamic drivers — about 3 mm thick — on a braided cable with a sturdy 3.5 mm plug and an inline control with a mic. The idea is simple: if you already own a sleep headband, this is the replacement speaker module that turns it back into a working headphone. No headband required in the box, just the speakers.
The reason the soft silicone angle matters here is comfort under pressure. Regular earbuds stick out, and when you roll onto your side that bulk digs into your ear. A 3 mm speaker, tucked into a fabric headband, barely registers. That is exactly the situation MMUSS is built for: side sleepers, people who fall asleep to audiobooks, and anyone sharing a bed with someone who does not want to hear it. The 32 ohm impedance and 120 dB sensitivity mean it is easy to drive from a phone, tablet or laptop, and the 20 Hz–20 kHz range covers spoken word and music without fuss.
Who should skip it? Anyone who wants wireless freedom, active noise cancelling, or a product that works out of the box without a headband. There is no Bluetooth here, no battery, and no noise control at all — the noise control field is literally "None." If your phone has no headphone jack and you have no adapter, look elsewhere. And if your goal is to mute the world rather than listen to it, this is the wrong tool entirely.
GyOnyx 6: Who It's For
The design detail I like most is the moldable fit. Instead of pushing deep into the canal the way foam plugs do, these shape to the outer ear for a pressure-free seal you can pinch and adjust — the maker even notes you can trim off excess silicone to suit your canal. For side sleepers this matters: a plug that sits shallower is far less likely to throb against a pillow. They are also pitched at sensitive skin, which is a real consideration if you wear plugs every single night.
Who should skip them? Anyone who wants to hear audio while they sleep. There is no speaker, no cable and no app — GyOnyx 6 is silence, not sound. Also note every plug ships at one size; you are expected to customise the fit yourself rather than pick from a size range. If you need precise, repeatable noise reduction measured in decibels, this is a general-purpose reducer, not a lab instrument.
• Best for side sleepers who want audio → MMUSS Sleep. The 3 mm profile is the whole point.
• Best for pure noise blocking → GyOnyx 6. Snoring, traffic, flights, concerts, shared rooms.
• Best for swimming and showers → GyOnyx 6. Fully waterproof silicone; MMUSS has no water rating in its specs.
• Best if you already own a sleep headband → MMUSS Sleep. It is a direct replacement for worn-out speakers.
• Best for wireless or app-based features → neither. MMUSS is wired 3.5 mm; GyOnyx has no electronics at all.
• Best for multiple people or spares → GyOnyx 6. Six pairs and six cases go a long way.
• Best for travel kits → GyOnyx 6. Each pair has its own pocket-sized case.
• Best for a gift → either, honestly. MMUSS frames itself as a comfort gift; a six-colour plug set is easy to share.
My Verdict
If I had to pick one, I would buy GyOnyx 6 — not because it is more advanced, but because it solves the problem most sleepers actually have: a noisy room. Six pairs, six cases, waterproof, washable, and a moldable fit that does not jam into your ear canal. That is a lot of useful redundancy for the money, and it covers sleep, travel and swimming in one box.
what are the best earbuds to sleep in
For pure comfort, look for a thin, soft, low-profile design rather than a standard earbud — bulk is what causes pain when you roll onto your side. MMUSS Sleep's speakers are only about 3 mm thick, which is why they suit side sleepers who want audio. If you do not need sound at all, GyOnyx 6's moldable silicone plugs sit shallow in the ear instead of deep in the canal.
are there earbuds for sleeping
Yes, and they split into two types. Audio sleep headphones, like the MMUSS Sleep speaker set, play music or podcasts quietly through a headband using a 3.5 mm wired connection. Passive options, like GyOnyx 6, are silicone ear plugs that reduce outside noise instead of playing anything — great for snoring, traffic and travel.
how to put on silicone earbuds
With moldable silicone, you warm and shape the plug between your fingers, then press it into the outer ear to form a seal — no deep insertion needed. GyOnyx 6 works this way, and you can pinch off excess silicone if a plug feels too large. For MMUSS Sleep, you slide the thin speakers into the pocket of a sleep headband and wear the headband as normal.
Yes. MMUSS Sleep is sold as a replacement speaker module, not a complete headband, so it assumes you already own one with a compatible pocket. If you do not, factor that into your decision. GyOnyx 6 has no such requirement — it works straight out of its case.
