If you want a dedicated sleep companion with extended battery life and active noise cancellation for side sleeping, choose Ttbesmi SM01; if you need versatile waterproof earbuds that can handle swimming and offer a lockout mode to prevent accidental touches at work, choose Piegricdiat Invisible Sleep Headphones.
• Ttbesmi SM01: Its biggest strength is the ultra-lightweight design specifically engineered for side sleepers with small ear canals, backed by 42 hours of total battery life; however, it lacks waterproofing and relies on standard touch controls that might be prone to accidental presses during restless sleep.
• Piegricdiat Invisible Sleep Headphones: The standout feature here is its IPX6 waterproof rating allowing for underwater use and a specialized "sleep mode" that disables physical buttons to prevent interruptions; the trade-off is a heavier build and a slightly shorter single-charge playtime compared to the Ttbesmi's case-extended endurance.
• Best For: Pick the Ttbesmi SM01 if your primary goal is uninterrupted, all-night rest with superior comfort for tight ear shapes. Choose the Piegricdiat if you need a dual-purpose device for sleep and water sports, or if you require strict button locking for use in busy environments like construction sites.
The Ttbesmi SM01 is built with a singular, focused purpose: getting you through the night without discomfort. The design philosophy here centers on the reality that many people have small ear canals or struggle with bulkier headphones when lying on their sides. By utilizing a split silicone design combined with U-shaped ear flaps, this product aims to hug the curve of the ear canal rather than just sitting inside it. This isn't just about staying put; it is about eliminating the pressure points that often wake people up after an hour or two of wear.
For someone who tosses and turns or sleeps exclusively on their side, the weight of these earbuds is a critical factor. Each unit weighs only 0.12 ounces, making them among the lightest options available on the market. This minimal mass means you are unlikely to feel the plastic or liquid silicone enclosure pressing against your inner ear, even if you wake up in the middle of the night and realize they are still there. The material choice—liquid silicone—is soft enough to avoid the swelling and irritation common with traditional hard plastic buds, which is a significant advantage for long-term overnight wear.

Battery anxiety is a real issue for anyone trying to listen to audiobooks or white noise through the entire duration of a night shift or a long commute before bed. The Ttbesmi SM01 addresses this with a 5-hour continuous playtime on a single charge, but the real hero is the charging case. That case extends the total usage time to 42 hours, meaning you can go almost a week without hunting for a USB-C cable. With fast charging capabilities, a mere 10-minute plug-in grants 90 minutes of listening, which is perfect for quick top-ups if you forget to charge them before bed. If you are looking for extra bass gaming headphones for construction work that double as a reliable sleep aid, the Bluetooth 5.4 connection ensures a stable link over short distances, though the lack of waterproofing limits its utility outside dry environments.
The Piegricdiat Invisible Sleep Headphones take a different approach, prioritizing versatility and security features over pure sleep-specific optimization. While they are marketed as sleep earbuds, the inclusion of an IPX6 waterproof rating fundamentally changes what these devices can do. You are not limited to a bedroom environment; these buds can withstand sweat, rain, and submersion in water for more than six hours continuously. This makes them a unique candidate for anyone who needs a pair of headphones that can transition from a quiet night's rest to a swim session or a rainy outdoor workout without hesitation.
A distinct feature that sets this model apart for professional use is the dedicated "sleep mode." In this state, any physical button press on the earbud itself is disabled, forcing the user to control playback entirely through their smartphone. This is a crucial detail for individuals working in high-noise or safety-sensitive environments, such as those needing wireless gaming headphones for construction work where accidental activation could be distracting or dangerous. The ability to hide the earbuds discreetly while maintaining audio quality without the risk of fumbling with controls makes them ideal for hiding in plain sight during shifts or travel.
However, the design choices here reflect a balance between comfort and durability. While they utilize proprietary skin-soft silicone eartips and caps, the item weight is listed at 1.6 ounces, which is significantly heavier than the Ttbesmi option. This might make a difference for those with very sensitive ears who are accustomed to feather-light sleep aids. The Bluetooth 5.3 chip offers wide compatibility and stable connections, but the focus on underwater performance suggests a different set of priorities. If you need rechargeable wireless headphones for construction work that also serve as a shower-safe or pool-side companion, this model covers bases the other one simply cannot. The 3D surround sound technology aims to deliver a rich audio experience, but users must accept that the form factor is slightly more substantial to accommodate the waterproof seals and the robust build required for wet conditions.
• Best for side sleepers with small ears → Ttbesmi SM01, due to its specific split-silicone design and minimal 0.12 oz weight per earbud.
• Best for water activities → Piegricdiat Invisible Sleep Headphones, boasting an IPX6 rating that supports swimming and snorkeling.
• Best for battery longevity → Ttbesmi SM01, offering a massive 42 hours of total playtime with its charging case versus the Piegricdiat's standard single-charge focus.
• Best for accidental touch prevention → Piegricdiat Invisible Sleep Headphones, featuring a sleep mode that locks physical buttons to prevent interference.
• Best for fast recharging → Ttbesmi SM01, capable of gaining 90 minutes of listening time from just 10 minutes of USB-C charging.
• Best for heavy-duty work environments → Piegricdiat Invisible Sleep Headphones, as the button-lock mode and rugged waterproofing suit active job sites better.
• Best for deep silence and ANC → Ttbesmi SM01, equipped with Active Noise Cancellation to block out ambient room noise.
• Best for lightweight all-day wear → Ttbesmi SM01, whose tiny profile reduces fatigue during extended periods of use.
In my opinion, the Ttbesmi SM01 is the superior choice for the vast majority of buyers whose primary goal is sleep. The engineering around the fit and weight shows a genuine understanding of the physical challenges of sleeping with electronics, and the 42-hour battery life removes the daily friction of charging. However, I would recommend the Piegricdiat Invisible Sleep Headphones if you have a specific need for waterproofing or require that button-lock feature for use in noisy, active settings like construction work. For a dedicated sleep solution, the Ttbesmi wins on comfort and endurance; for a rugged, multi-environment tool, the Piegricdiat holds the edge.
Yes, both models offer wireless connectivity suitable for job sites, but the Piegricdiat is better suited for loud environments due to its button-lock mode which prevents accidental stops, while the Ttbesmi offers excellent noise cancellation for focus.
The Ttbesmi SM01 uses a split silicone and U-shaped flap design specifically to stay secure for side sleepers, whereas the Piegricdiat relies on standard silicone tips that may require a specific fit to remain stable during movement.
Only the Piegricdiat Invisible Sleep Headphones are rated IPX6 waterproof and can be used underwater for extended periods; the Ttbesmi SM01 does not carry a waterproof rating and should be kept dry.
The Ttbesmi SM01 provides up to 5 hours of playtime on one charge, while the Piegricdiat model offers comparable listening time but lacks the extensive case extension found in the Ttbesmi ecosystem.
