If you want wired earbuds with a dual-driver design for listening while fishing, choose TRUTHEAR x Crinacle Zero; if you need a low-profile Bluetooth pair for sleep and everyday use, choose goazzzl Flat Sleep Earbuds. For fishing, the TRUTHEAR is the more relevant fit of these two: it connects by cable and has no stated wireless or water-protection features, while the goazzzl is designed around sleep comfort rather than outdoor use.
TRUTHEAR x Crinacle Zero vs goazzzl Flat Sleep Earbuds at a Glance
• goazzzl Flat Sleep Earbuds: Its flat sleep pair, separate mini pair, and Bluetooth connection offer more flexibility; the trade-off is that its stated design priorities are sleep and daily wear, not fishing.
• Sound approach: TRUTHEAR is described as having punchy bass, a warm and natural presentation, and bright treble; goazzzl is presented as delivering softer sound for relaxation and focus.
• Power and connection: TRUTHEAR is wired, so it does not rely on a listed battery; goazzzl is wireless, with a stated average battery life of six hours.
• Who each suits: Choose TRUTHEAR for wired listening and its two-driver audio design; choose goazzzl if a flat profile for side sleeping and Bluetooth matter more.
The TRUTHEAR x Crinacle Zero is a wired, in-ear model built around two dynamic drivers: one measures 10 mm and the other 7.8 mm. Its 3.5 mm connection makes it a straightforward choice for a compatible audio source, without the charging routine that comes with a wireless pair. The published frequency range is 20 Hz to 40.5 kHz, and its impedance is listed as 17.5 ohms.
The sound description points to bass with real presence, while aiming to keep higher frequencies clear and the overall presentation warm and natural. The product information also describes the treble as bright without being irritating and says the tuning is intended to remain comfortable over longer listening sessions. That makes the Zero a plausible pick for someone who wants music or other audio while doing a task, rather than an earbud built specifically to disappear against a pillow.

For fishing, I would pick it over the goazzzl if my priority were wired listening and I had a compatible device with a 3.5 mm jack. But there is an important limit: the listed information does not describe water resistance, a secure-sport fit, or noise control. I would not treat it as a purpose-built fishing or weatherproof earbud. Skip it if you need Bluetooth, a sleep-friendly flat shape, or an explicit water-protection feature.
goazzzl Flat Sleep Earbuds: Who It's For
The goazzzl set is designed around two different in-ear pairs: ultra-flat earbuds for sleep and mini earbuds for work or everyday use. The low-profile sleep pair is intended to reduce pressure when lying on your side, while the smaller pair gives you another option for daytime wear. That two-pair setup is its clearest practical distinction from the single wired listening approach of the TRUTHEAR.
This is the more natural choice for someone who wants earbuds for bed, travel, or low-key listening without a cable. For fishing, though, those sleep-focused advantages do not answer the key outdoor questions: the supplied details do not specify water resistance, how securely the earbuds stay put during active movement, or a dedicated outdoor-use design. The listing calls them waterproof, but the provided product information does not give a protection rating or conditions, so I would not assume more than that broad claim. I would skip them if fishing is the main reason for buying and you want clearly documented outdoor protection.
• Best fit for wired listening → TRUTHEAR x Crinacle Zero. It uses a 3.5 mm jack and does not depend on a listed battery.
• Best fit for side sleeping → goazzzl Flat Sleep Earbuds. Its flat pair is specifically designed for a lower-profile feel while lying down.
• Best for a two-driver design → TRUTHEAR x Crinacle Zero. Its dynamic drivers measure 10 mm and 7.8 mm.
• Best for choosing between sleep and daytime earbuds → goazzzl. The set includes a flat sleep pair and a mini pair for work or daily use.
• Best for Bluetooth use → goazzzl. Bluetooth 5.4 is listed, while the TRUTHEAR is wired.
• Best for avoiding battery charging → TRUTHEAR x Crinacle Zero. Its cable connection means there is no earbud battery to recharge.
• Best for stated touch control → goazzzl. Touch control is listed alongside its wireless design; the TRUTHEAR also lists touch control, but it is wired.
• Better fit for fishing between these two → TRUTHEAR x Crinacle Zero, with caveats. Its wired format may suit a compatible device, but neither product’s provided details establish a fishing-specific fit or clear protection against water.
The fishing choice deserves more caution than a simple feature checklist suggests. “Best open ear earbuds for fishing” and “best on ear headphones for fishing” describe different kinds of gear from these in-ear models. Neither product is described as open-ear or on-ear. Likewise, someone searching for the “best touch control headphone for fishing” may find the goazzzl’s Bluetooth and touch controls convenient, but those features alone do not make it suitable for wet conditions or active use.
For non-fishing use, the contrast is much easier. The TRUTHEAR is the listening-oriented pick: two dynamic drivers, a wired connection, and a sound description emphasizing punchy bass with a warm, bright-edged presentation. The goazzzl is the convenience-and-comfort pick: Bluetooth, two distinct earbud pairs, a low-profile sleep option, and a charging case. They are not close substitutes in design, even though both sit in the in-ear category.
My Verdict
In my opinion, I would choose the TRUTHEAR x Crinacle Zero for fishing if I wanted wired listening and had a compatible 3.5 mm source. Its dual-driver design and cable make it the more relevant of these two for that use, but I would not mistake it for a purpose-built outdoor earbud because the listed details do not establish water protection. For sleep, travel, or Bluetooth convenience, I would choose the goazzzl instead.
Of these two, the TRUTHEAR is the more relevant choice if wired listening suits your setup. Neither product’s listed details confirm a fishing-specific design or clearly documented water protection.
Can I use the goazzzl Flat Sleep Earbuds without Bluetooth?
The goazzzl uses Bluetooth 5.4 and has no headphone jack listed. The TRUTHEAR connects by wire through a 3.5 mm jack.
Yes. The set includes an ultra-flat pair described as intended for side sleepers, plus a separate mini pair for work and everyday use.
The goazzzl lists an average battery life of six hours and comes with a wireless charging case. The TRUTHEAR is wired, so its product information does not list an earbud battery life.
