• MEE audio M6 — biggest strength: a genuine noise-isolating design built around a closed-back earpiece and a huge eartip kit (7 pairs, including Comply memory foam), plus memory wire earhooks that hold the monitor in place so the seal survives movement.
• MEE audio M6 — biggest trade-off: it is a wired monitoring tool first. You have to fit it correctly, and if the seal is wrong the sound goes thin — the brand itself warns about this. It also uses a 3.5 mm jack, not USB-C.
• SUYUZREY Ear buds — biggest strength: a USB-C plug with an integrated DAC and an inline microphone with ENC for calls, so it slots straight into a modern phone or laptop that has no headphone jack.
• SUYUZREY Ear buds — biggest trade-off: its noise control is passive only, achieved through soft silicone ear tips. There is no memory wire, no replaceable cable and no foam tip option in the box.
• Who each pick is for: MEE audio M6 for musicians, stage and studio users, and anyone who wants a locked-in isolating fit with swappable cables; SUYUZREY Ear buds for commuters, call-heavy workers and USB-C device owners who want simple plug-and-play.
The M6 PRO is a second-generation in-ear monitor, and everything about the design points at one job: getting a reliable seal so outside noise drops and the music arrives intact. The 10 mm dynamic driver uses a 5µm diaphragm and an aluminium voice coil, which the spec sheet frames as more precise movement than a conventional driver — the practical result being clearer mids and smoother highs rather than a bass-only thump. Impedance is 16 ohm and sensitivity is 100 dB, so it is easy to drive from a phone, laptop or interface without extra amplification.
Where this monitor really separates itself is fit. You get seven pairs of eartips, including Comply T-Series memory foam, and flexible memory wire that bends to the shape of your ear and stays there. That combination is what makes the isolation work: the foam and silicone tips seal the canal, the closed-back earpiece keeps sound in, and the earhook stops the monitor from working loose when you move. If you have ever had an earbud slide out mid-commute or mid-set, this is the design that fixes it. MEE audio also includes a note that thin, tinny sound usually means the seal is wrong and you should try another tip size — useful honesty, and a reminder that in-ears reward a couple of minutes of fitting.
The reliability story is the other half. The cable is detachable and user-replaceable, which is rare at this end of the market, and the sweat-resistant build suits rehearsals, gym sessions and long listening days. Two cables ship in the box: a regular audio cable and a headset cable with mic and remote for laptops and mobile devices, plus a hard-shell carrying case, a 1/4" adapter and six silicone tip sets alongside the Comply foams. It works with anything that has a standard 3.5 mm or 6.3 mm jack.
SUYUZREY Ear buds: Who It's For
The SUYUZREY Ear buds take the opposite approach. Instead of tuning and tip options, the headline is connectivity and calls. The plug is USB-C, and there is an integrated DAC on board, which matters because a plain USB-C dongle has to convert digital audio somewhere. Here the conversion is built into the earbud, and the spec sheet pairs that with dynamic bass and high fidelity — crisp vocals, detailed instrumentals and punchy low end for music, podcasts and video.
The second half of the pitch is the microphone. Built-in ENC, or Environmental Noise Cancellation, works on your outgoing voice rather than on what you hear: it suppresses background chatter, traffic and ambient noise so callers get you clearly on work calls, video conferences and personal chats. That is a different job from the M6's isolation, and it is worth being clear about the distinction. The SUYUZREY's noise control is listed as passive — the ergonomic soft silicone tips create a snug seal that blocks external sound and adds immersion, which is the same physical principle the M6 uses, just without the foam tips and earhook hardware.
Comfort and simplicity are the strengths here. The earbuds are lightweight, the tip seal is designed to stay put through commutes, workouts and long workdays, and the inline button remote handles calls, voice assistants and playback without touching your device. Impedance is 32 ohm and sensitivity is 102 dB, with a 20 Hz frequency response — numbers that describe an easy, undemanding listen rather than a monitoring tool. It ships as a single wired unit in a retail box: no spare cable, no case, no tip assortment.
Buy it if your devices are USB-C, you take a lot of calls, and you want one cable that does everything without adapters or setup. Skip it if you need a replaceable cable, multiple tip sizes or a fit that survives heavy movement — or if your gear only has a 3.5 mm jack.
Side-by-Side: Which Should You Choose?
• Best for phone calls and meetings → SUYUZREY Ear buds. Inline microphone with ENC aimed at making your voice clear over background noise.
• Best for USB-C devices → SUYUZREY Ear buds. USB-C plug with an integrated DAC, no adapter required.
• Best for older gear and audio interfaces → MEE audio M6. Standard 3.5 mm jack plus a 1/4" adapter in the box.
• Best for durability and repairability → MEE audio M6. Detachable, user-replaceable cables and a sweat-resistant build; the SUYUZREY is a sealed single unit.
• Best for going straight from box to ears → SUYUZREY Ear buds. One cable, one plug, button remote — nothing to configure.
• Best for stage, studio and critical listening → MEE audio M6. A 16 ohm, 100 dB monitor with a 5µm diaphragm and aluminium voice coil, tuned for accurate mids and smooth highs.
• Best for workouts and long wear → either, with a caveat. Both are in-ear and lightweight, but the M6's earhooks and foam tips are the more secure option when you move a lot.
I would buy the MEE audio M6. In my opinion it is the more complete product for anyone who actually cares about noise isolating headphones, because the isolation is engineered into the package — closed-back earpieces, seven pairs of tips, memory foam and earhooks that hold the seal — rather than left to a single silicone tip. The replaceable cable and the two-cord kit also mean it keeps working when a cable eventually fails, which is the most common way wired earbuds die. The SUYUZREY Ear buds are a sensible pick if USB-C and clear calls are your priority, but if isolation and longevity matter more, the M6 is the one I would keep.
how to noise cancelling headphones work
Active noise cancelling uses microphones and electronics to generate a signal that cancels incoming sound. Neither of these products does that. Both rely on passive isolation: an in-ear tip that seals your ear canal so less outside noise reaches your eardrum. The M6 adds Comply memory foam tips and a closed-back earpiece; the SUYUZREY adds soft silicone tips and ENC, which cleans up your outgoing voice on calls rather than what you hear.
how to use noise cancelling headphones
Fit comes first. Push the eartip gently into your canal, then check the seal — MEE audio notes that thin, tinny sound with weak bass usually means the seal is wrong, so try another tip size. Once sealed, just plug in and listen. The M6's memory wire bends over your ear and holds position; the SUYUZREY's inline remote handles playback, calls and voice assistants from the cable.
how to test noise cancelling headphones
Put them in with nothing playing and listen to steady background noise, then cup your hands over your ears — a good seal makes the world noticeably quieter and your own voice sound hollow. Next, play something bass-heavy: if the low end sounds thin, the tip is not sealing. On the M6, cycle through the included tip sizes and the foam pair to find your match. On the SUYUZREY, try the silicone tips and check the mic on a real call.
do noise isolating earbuds block all background noise
No. Passive isolation reduces noise, it does not erase it. Foam tips like the Comply set included with the M6 generally cut more than silicone because they expand to fill the canal, and memory wire helps keep that seal intact while you move. That lower noise floor is what lets you listen at safer volumes. If you want total silence, you need active noise cancelling, which neither of these models offers.
