If you want one pair of earbuds that does everyday music, calls and workouts with a punchy sound and a sustainable build, choose Skullcandy Smokin Buds; if you need earbuds you can fall asleep in — specifically on your side, with small ears — choose goazzzl Sleep Earbuds. They are not competitors in the same race. One is a general-purpose true wireless set with EQ modes and sweat resistance; the other is a sleep-first design built around 3-gram buds and a no-light, no-pressure fit. Below I break down exactly where each one wins, where each one gives something up, and which one I would actually buy depending on how you listen.
• Skullcandy Smokin Buds — biggest strength: A complete everyday package: three preset EQ modes, IPX4 sweat and water resistance, rapid charge, touch controls and a 50% renewable-plastic build.
• Skullcandy Smokin Buds — biggest trade-off: The rounded-tip in-ear shape and 6 mm dynamic drivers are made for general listening, not for lying on your side; nothing here is designed around sleep comfort.
• goazzzl Sleep Earbuds — biggest strength: Ultra-light 3.0 g mini buds with a semi in-ear fit and no flashing lights, explicitly engineered so side sleepers and small ear canals can wear them for hours.
• goazzzl Sleep Earbuds — biggest trade-off: No active noise control, no EQ modes, no water-resistance rating, and earbud battery life is listed at around 5 hours per charge.
• Who each is for: Skullcandy Smokin Buds for commuters, gym-goers and general listeners who want features and durability; goazzzl Sleep Earbuds for side sleepers, small-eared users and anyone who wants invisible buds for sleep, study or quiet focus.
The Smokin Buds is the more versatile product of the two, and it is versatile in a very deliberate way. Skullcandy tuned it for "supreme sound" with a 6 mm dynamic driver, 16 ohm impedance, 104 dB sensitivity and a 20 Hz–20 kHz frequency range — a spec set that points to an easy-to-drive, lively everyday listen rather than a flat studio monitor. On top of that you get three preset EQ modes (Music, Movie, Podcast) that you switch with four taps on either earbud, plus touch controls for volume, calls and your phone's local voice assistant. If you have ever wished your earbuds had a one-touch "movie" setting instead of digging into an app, that is exactly what this is.
So who should buy it? Anyone whose earbuds live in a backpack, a gym bag or a jacket pocket. Commuters, students, podcast listeners, casual gym-goers. Who should skip it? If your main use case is falling asleep on your side, this is the wrong tool — the rounded-tip in-ear shape and standard housing are built for upright, active listening, and Skullcandy makes no sleep-comfort claim here. Sleepers should look at the other pair.
goazzzl Sleep Earbuds: Who It's For
The goazzzl Sleep Earbuds start from a completely different brief: comfort while horizontal. The core of the design is a 3.0 g mini bud with a semi in-ear shape that sits gently rather than plugging tightly. That combination is specifically aimed at two groups — side sleepers who get sore ears from bulky buds pressing into the pillow, and people with small ear canals who find standard earbuds either fall out or ache after twenty minutes. The semi in-ear fit is the key detail: it is designed to reduce that sealed, plugged-up feeling, which is exactly what you want at 2 a.m.
The second big feature is discretion. After pairing, these buds show no flashing lights, so nothing blinks in a dark bedroom or a quiet office. That single design choice makes them genuinely usable for sleep, the library, a lecture hall or a shared workspace where a pulsing LED is the last thing you want. Connectivity is handled by Bluetooth 5.4 with instant pairing when you open the case and touch controls for music, calls and volume, so you are not reaching for your phone in the dark.
Battery is where the two products trade places. goazzzl lists roughly 4–5 hours per charge in the buds and up to 35–40 hours with the case, and the case has an LED display that shows the battery level the moment you open it — a genuinely useful touch for something you use overnight. On the flip side, the spec sheet shows no active noise control, no EQ modes and no IP water-resistance rating, and the enclosure is standard plastic. Total battery life is listed at 5 hours for the buds themselves. There is a 3-year manufacturer warranty, which is unusually long for this category.
Buy these if sleep, side-lying comfort and small-ear fit are your priorities, or if you want buds that disappear visually during the day. Skip them if you need sweat-proofing for hard workouts or want to shape your sound with EQ presets — that is not what this product is built to do.
Side-by-Side: Which Should You Choose?
• Best for small ear canals → goazzzl Sleep Earbuds. The ultra-compact shape targets small ears directly, where standard in-ears tend to fall out or hurt.
• Best for total battery life → goazzzl Sleep Earbuds. Up to 35–40 hours with the case beats Skullcandy's up-to-20-hour figure, even though per-charge bud life is shorter.
• Best for workouts and weather → Skullcandy Smokin Buds. The IPX4 rating is the only water-resistance claim on either sheet.
• Best for sound customization → Skullcandy Smokin Buds. Three preset EQ modes (Music, Movie, Podcast) versus none on the goazzzl.
• Best for fast top-ups → Skullcandy Smokin Buds. Rapid Charge delivers 2 hours of listening from a 10-minute charge — handy when you forgot to plug in.
• Best for staying unnoticed → goazzzl Sleep Earbuds. No flashing lights after pairing, which matters in a dark bedroom or a quiet office.
• Best for a sustainable build and long warranty coverage → split call. Skullcandy uses 50% renewable plastics and recyclable packaging with a 1-year warranty; goazzzl uses standard plastic but backs it with a 3-year warranty.
• Best for a quick battery read → goazzzl Sleep Earbuds. The LED display on the case shows charge level as soon as you open it.
In my opinion, these two should not be weighed against each other at all — they solve different problems, and the "better" one depends entirely on when you wear them. If I were buying for sleep, side-lying comfort or small ears, I would take the goazzzl Sleep Earbuds without hesitation: 3.0 g buds, a semi in-ear fit, no lights, a battery display and a 3-year warranty are exactly the right priorities for that job. If I wanted one pair for commuting, music, calls and workouts, I would take the Skullcandy Smokin Buds for the EQ modes, IPX4 rating and rapid charge. For most people who already have a normal set of earbuds and are shopping specifically for sleep, goazzzl is the pick.
FAQ
It depends how you measure it. Skullcandy lists up to 20 hours total (8 in the buds, 12 in the case) plus Rapid Charge. goazzzl lists about 4–5 hours per bud charge but up to 35–40 hours with the case, so the case carries more of the load.
They use passive noise cancellation through the in-ear seal — there is no active noise cancelling listed. The goazzzl sheet lists noise control as "None," relying on the semi in-ear fit instead.
Value depends on your use case, not just the spec list. Skullcandy gives you more features per pair — EQ modes, IPX4, rapid charge — while goazzzl gives you sleep-specific comfort, a battery display and a longer 3-year warranty. Check the current price on Amazon for both before deciding, since your budget will settle the tie faster than the spec sheet will.
