If you want wired, multi-driver sound for focused listening and sports workout sessions where a cable works for you, choose SHANLING SONO in-Ear Headphones; if you need compact wireless earbuds designed for sleep, choose goazzzl Sleep Earbuds. The key difference is straightforward: SONO prioritizes a hybrid audio setup and replaceable sound-tube filters, while goazzzl emphasizes a small fit, touch controls, and IPX5 water resistance.
• SHANLING SONO’s biggest strength: A wired 2DD+1BA hybrid design with two pairs of sound-tube filters; its trade-off is the 3.5 mm cable and lack of listed noise control.
• goazzzl’s biggest strength: A compact wireless design intended for sleep, with soft silicone tips, touch controls, and IPX5 waterproofing; its trade-off is that the listed features give no driver configuration or frequency-response figures to compare with SONO.
• Choose SONO if you want a wired in-ear monitor and value its multi-driver arrangement and included tuning filters.
• Choose goazzzl if a discreet wireless fit for nighttime use matters more than a wired listening setup.
• For sports workout use, goazzzl has the clearer documented advantage for moisture exposure because it specifies IPX5 waterproofing; SONO’s sheet does not list a water-resistance rating.
SONO is a wired in-ear monitor built around two dynamic drivers and one balanced armature driver per earphone. The 9.2 mm bio-diaphragm and 6.8 mm liquid-crystal diaphragm dynamic drivers handle the low and mid frequencies, while a custom balanced armature is assigned to high frequencies. SHANLING also includes two pairs of replaceable sound-tube filters, giving the package a tuning option that goazzzl’s listed features do not mention.
The connection is a 3.5 mm plug, and the headphones have a 16-ohm impedance and a stated frequency range of 16–40,000 Hz. The CNC-machined metal shells weigh 8.6 g per earphone, according to the product details. Four pairs of eartips, a cable, and a storage box are also listed. These details make SONO a plausible fit for someone who prefers a wired setup and wants its particular multi-driver configuration rather than wireless convenience.
I’d skip SONO if you need earbuds designed specifically for sleeping on your side, want touch controls, or need documented sweat or water resistance. It has no listed noise-control feature, and its cable is a practical consideration during movement. For sports workout sessions, that means the fit and cable arrangement may matter more than the technical audio setup; the product information does not claim water resistance.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

They connect over Bluetooth, pair automatically with the last device when removed from the charging case, and offer touch controls for playback, volume, calls, and voice assistants. The listed compatibility includes iOS, Android, Mac, and most Bluetooth-enabled devices. The product information also specifies sound isolation and IPX5 waterproofing. Those features make goazzzl more versatile for everyday wireless use and workouts, although the sheet does not provide battery-life figures or a Bluetooth version.
The trade-off is that the provided details do not specify a driver arrangement, frequency range, or a wired listening option. If your priority is evaluating a clearly described multi-driver audio design, SONO offers more technical detail. And while goazzzl is described as comfortable for sleep, shoppers should not confuse that with a claim that it blocks every surrounding sound.
• Best for a wired listening setup → SHANLING SONO in-Ear Headphones. It uses a 3.5 mm plug, while goazzzl is Bluetooth.
• Best for sleep and side-sleeping comfort → goazzzl Sleep Earbuds. Its compact design and soft silicone eartips are specifically described for nighttime use.
• Best for a documented multi-driver design → SHANLING SONO. It combines two dynamic drivers with one balanced armature driver.
• Best for touch controls and automatic reconnecting → goazzzl. The listed controls cover playback, volume, calls, and voice assistants, and the earbuds reconnect to the last paired device.
• Best for documented water resistance during a workout → goazzzl. Its IPX5 rating is specified; no water-resistance rating is listed for SONO.
• Best if you want replaceable tuning filters → SHANLING SONO. Two pairs of sound-tube filters are included.
• Best for a phone or computer without a headphone jack, if it supports Bluetooth → goazzzl. SONO instead has a 3.5 mm connection, so device compatibility depends on the available port or an appropriate adapter.
• Best for someone seeking hifi stereo open ear earbuds for video calls → neither is an open-ear design. SONO is an in-ear monitor, and goazzzl is a compact in-ear wireless earbud; goazzzl does list call controls, but neither sheet describes an open-ear fit.
• For someone searching for the best sweat resistant sleep headphones for school → goazzzl is the closer fit to the sleep-and-moisture brief. It is described for sleep and specifies IPX5 waterproofing, but neither product’s details establish suitability for every school setting.
• For a “transparency mode gaming headset for motorcycle” → neither matches that description. SONO lists no noise control, and goazzzl lists sound isolation; neither sheet specifies transparency mode or motorcycle use.
My Verdict
goazzzl is the more directly sleep-focused choice: its compact shape and soft silicone eartips are described for nighttime use and side sleeping. SONO is a wired in-ear monitor, and its listed features do not identify it as a sleep design.
goazzzl has a documented advantage for workouts because its product information specifies IPX5 waterproofing. SONO is wired and has no listed water-resistance rating, so its details do not establish the same protection.
Neither product’s listed details specify active noise cancellation or transparency mode. SONO lists no noise control; goazzzl lists sound isolation, which is a different description and should not be treated as a promise of active cancellation.
SONO provides more detail about its audio hardware: two dynamic drivers and a balanced armature driver, along with replaceable sound-tube filters. goazzzl is described as delivering clear, balanced audio, but the provided information does not give comparable driver or frequency-response figures.
