How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the more feature-packed everyday earbuds with the strongest noise cancellation and hi-res codec support, choose QCY MeloBuds N70; if you need ultra-thin sleep-first earbuds built for side sleepers, choose Ertuly T33. These two are aimed at different jobs, and once you see what each one is actually designed to do, the decision gets a lot simpler.
• QCY MeloBuds N70 — biggest strength: A full-featured everyday package — hybrid ANC rated up to -56dB, LDAC hi-res audio with a dual-driver setup, multipoint Bluetooth 6.0, wireless charging and up to 50 hours of total playtime.
• QCY MeloBuds N70 — biggest trade-off: It's a standard in-ear bud, not a sleep-specific design, so side sleepers who need a flush, near-weightless fit should think twice.
• Ertuly T33 — biggest strength: Purpose-built for sleep — roughly 3g per bud, an ultra-thin shell, a sleep mode that mutes alerts and blocks accidental touches, plus hybrid ANC rated to block up to 98% of noise.
• Ertuly T33 — biggest trade-off: It skips some of the "audiophile" extras — no LDAC, no multipoint, no wireless charging — and charges over USB-C only.
• Who each pick is for: QCY MeloBuds N70 is for commuters, workers and listeners who want one pair to do everything well; Ertuly T33 is for people who wear earbuds in bed and need comfort and quiet above all.
The MeloBuds N70 reads like a spec sheet built for people who want one pair of earbuds to cover the whole day. The headline is its hybrid active noise cancellation: six sensors feed QCY's PureSilenz processing, which the data sheet rates at up to -56dB of noise reduction. That's the kind of figure aimed at plane engines, train rumble and open-plan office chatter. Add in-ear detection (music pauses when you pull a bud out and resumes when you put it back) and the whole thing feels tuned for stop-start daily use rather than lying in bed.
Sound is where it separates itself from a sleep bud. QCY uses a dual-driver "DualCore" setup — a ring-shaped dynamic driver plus a MEMS tweeter — and supports LDAC, which the sheet says transfers about three times more data than regular Bluetooth. It also carries Hi-Res wireless audio. In practical terms, that's for people who stream higher-quality audio and care about separation between bass and treble, not just loudness. The QCY app lets you tune EQ and update firmware, so the sound is adjustable rather than fixed.
Battery and convenience round it out: up to 10 hours per charge and 50 hours with the case in normal mode, dropping to 7 and 35 hours with ANC on. Fast charging gives roughly 2 hours of use from a 10-minute top-up, and the case supports wireless charging. Bluetooth 6.0 brings multipoint (two devices at once) and Google Fast Pair for Android. IPX5 covers workouts, light rain and splashes, and QCY includes five eartip sizes (XS through XL).
Ertuly T33: Who It's For
The T33 starts from a different question: how do you make an earbud you can forget about at 2 a.m.? The answer here is size and weight. Ertuly describes an ultra-thin, lightweight shell at roughly 3g per bud, explicitly designed for side sleepers to avoid pressure points. If you've ever woken up with a sore ear from a normal bud, that's the problem this product exists to solve. The white plastic build and compact case match the low-key, sleep-first intent.
Noise handling is tuned the same way. The T33 uses dual-microphone hybrid ANC that the sheet rates at blocking up to 98% of disruptive sound — snoring, traffic, appliance hum. A triple-tap toggles between ANC and Transparency mode, so you can shut the world out or let a little back in. Then there's the sleep-specific feature the MeloBuds simply doesn't have: a sleep mode activated by four quick taps that mutes all alerts and blocks accidental touches, so rolling over doesn't skip your track or trigger a command.
Battery is built for all-night sessions: up to 8 hours per charge and 48 hours total with the case, recharging in about 1.5 hours via USB-C, with an LED indicator on the case. Sound comes from 13mm dynamic drivers — a bigger single driver than QCY's, tuned for balanced output with rich bass rather than hi-res codec support. Calls run through ENC microphones, and you can use both buds in stereo or either one alone, which is handy for taking a call with one ear free.
Buy it if you wear earbuds to sleep, share a room with a snorer, or want something light enough for travel and naps. Skip it if you want multipoint, wireless charging, LDAC or app-based EQ — none of that is part of this design.
• Best for the strongest everyday noise cancellation → QCY MeloBuds N70. Its hybrid ANC is rated up to -56dB with six sensors.
• Best for blocking snoring and sleep-time noise → Ertuly T33. Its hybrid ANC is rated to neutralize up to 98% of disruptive sound.
• Best for side sleepers → Ertuly T33. Roughly 3g per bud and an ultra-thin shape built to avoid pressure.
• Best for higher-quality music → QCY MeloBuds N70. LDAC and Hi-Res wireless audio with a dual-driver setup beat a single-driver design on paper.
• Best for total battery life → QCY MeloBuds N70. Up to 50 hours with the case (35 with ANC on) versus 48 hours for the T33.
• Best for charging convenience → QCY MeloBuds N70. Wireless charging plus a 10-minute fast charge for about 2 hours of use; the T33 charges by USB-C only.
• Best for switching between devices → QCY MeloBuds N70. Bluetooth 6.0 multipoint connects two devices at once; the T33 pairs instantly but doesn't list multipoint.
• Best for all-night comfort and unbroken sleep → Ertuly T33. Sleep mode mutes alerts and blocks accidental touch commands.
If I had to pick one, I'd buy the QCY MeloBuds N70 — in my opinion it's the better all-rounder, because it covers commuting, calls, workouts and higher-quality audio with multipoint, wireless charging and the stronger headline noise-cancellation figure. The Ertuly T33 is the smarter choice only if sleep is your main reason for buying, since its lightweight build and sleep mode are things the QCY simply doesn't offer. If you sleep in earbuds most nights, take the T33. If you want one pair for everything else, take the MeloBuds N70.
For sleeping, the Ertuly T33 is the better fit. It's designed for side sleepers with roughly 3g buds, an ultra-thin shape and a sleep mode that mutes alerts. The QCY MeloBuds N70 is a standard in-ear bud built for everyday listening, not bed use.
Does the QCY MeloBuds N70 have better noise cancellation than the Ertuly T33?
They're rated differently, so compare carefully. QCY quotes up to -56dB of hybrid ANC reduction, while Ertuly quotes up to 98% of noise blocked. Both use hybrid ANC, but QCY's figure is aimed at travel and commuting, while Ertuly's is tuned around sleep sounds like snoring and appliance hum.
The QCY MeloBuds N70 goes a little further overall. It offers up to 50 hours with the case (35 with ANC on) and up to 10 hours per charge, versus 48 hours total and 8 hours per charge for the Ertuly T33.
Yes, both handle calls and exercise. QCY uses six mics with AI noise reduction and IPX5 water resistance; Ertuly uses ENC mics, single-or-dual bud flexibility and a higher IPX6 sweat and water rating — so the T33 is slightly more protected against sweat.
Value depends on what you need, so check the current price on Amazon before deciding. If you want one versatile pair with LDAC, multipoint and wireless charging, the QCY MeloBuds N70 packs more features; if you specifically need sleep-friendly earbuds, the Ertuly T33 delivers something the QCY can't.
