If you want a replaceable foam tip to improve the fit and seal of compatible earbuds for laptop listening, choose COMPLY Memory Foam Replacement; if you need miniature Bluetooth earbuds for sleep and everyday wireless audio from a laptop, choose SZHTFX Sleep Earbuds. COMPLY is an accessory, not a complete headset; SZHTFX is a standalone wireless pair with its own charging case. The right choice turns on whether you already own compatible earbuds or need a separate set.
COMPLY Memory Foam Replacement vs SZHTFX Sleep Earbuds at a Glance
• COMPLY’s biggest strength: body-heat-activated foam molds to the ear and is designed to improve grip and sound isolation. Trade-off: it replaces tips; it does not include earbuds or Bluetooth.
• SZHTFX’s biggest strength: compact, 2.1-gram-per-ear wireless earbuds with a charging case and Bluetooth 5. Trade-off: each charge is described as lasting 3–5 hours, so longer listening requires the case.
• COMPLY is for someone who already has compatible earbuds and wants a foam tip; SZHTFX is for someone who needs a complete wireless pair, especially for sleep.
• The two products solve different problems. Their comfort, isolation, and connection features are not directly interchangeable.
COMPLY is a set of replacement ear tips made from memory foam. The material responds to body heat and conforms to the wearer’s ear, with the aim of creating a more customized fit. Its grip is intended to help keep compatible earbuds in place during everyday movement and workouts. A secure seal may also reduce outside noise and support bass and clarity.
I’d consider these if I already owned compatible earbuds and wanted to change the feel of their fit rather than buy a new wireless set. The sheet specifically names Powerbeats Pro, Powerbeats, and Flex as compatible, and says they are not compatible with Beats Studio Buds. Because fit depends on the earbud model, I’d check compatibility before choosing them.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-20 · 6 min read · Independent comparison
SZHTFX is a complete set of small wireless earbuds designed with sleep and a discreet in-ear fit in mind. Each earbud weighs 2.1 grams, and the canal-style design sits inside the ear. The listed sound-suppression performance is up to 24 dB; the product also claims to reduce sound leakage. Those features make it more directly suited to someone who wants earbuds for quiet listening or bedtime than a replacement-tip set.
For laptop use, SZHTFX offers Bluetooth 5 and no headphone jack. The earbuds are rated for 3–5 hours of use per charge, and the 300 mAh case is described as recharging them 3–5 times. The overall claim is up to 30 hours of use, but that includes repeated charging from the case rather than a single uninterrupted session. The listing also says the earbuds can connect separately to different devices and automatically reconnect after the initial pairing.
The design has clear limits. These are in-ear earbuds, not open-ear headphones, and their sleep-focused fit won’t suit everyone. The listed battery life per charge may be short for a long workday without access to the case. The data also does not specify sweat resistance, so I wouldn’t choose them on the assumption that they are the best sweatproof Bluetooth headset for laptop use. Their strongest case is compact wireless listening and sleep, not a broad set of work or workout features.
• You already own compatible Powerbeats or Flex earbuds and want different tips → COMPLY Memory Foam Replacement. It adds a foam fit; it does not replace the earbuds themselves.
• You need a complete Bluetooth pair for a laptop → SZHTFX Sleep Earbuds. They connect wirelessly over Bluetooth 5.
• You want foam that conforms to the ear with body heat → COMPLY Memory Foam Replacement. That molding is the defining feature of the tips.
• You want tiny earbuds aimed at side sleepers → SZHTFX Sleep Earbuds. Their stated weight is 2.1 grams per ear, and their design is intended to sit discreetly in the ear.
• You want a stated noise-suppression figure → SZHTFX Sleep Earbuds. The listed performance is up to 24 dB; COMPLY instead describes noise isolation from the seal created by foam tips.
• You need several hours of wireless playback, with extra charges in a case → SZHTFX Sleep Earbuds. The earbuds are listed at 3–5 hours per charge, with the case providing 3–5 recharges.
• You’re searching for the best volume limiting in ear earbuds for laptop listening → neither sheet provides a volume-limiting feature. Don’t assume either product includes a volume cap based on these specifications.
• You specifically want open ear earbuds for laptop use → neither is open-ear. COMPLY is an in-ear replacement tip, and SZHTFX is a canal-style in-ear earbud.
My Verdict
I’d choose COMPLY only if I already had compatible earbuds and wanted foam replacement tips for fit and isolation. For my laptop recommendation, I’d buy SZHTFX because it provides the earbuds, wireless connection, and case in one product.
No. They are replacement tips, not a listening device. You need compatible earbuds, and the listed compatibility includes Powerbeats Pro, Powerbeats, and Flex but excludes Beats Studio Buds.
They connect wirelessly through Bluetooth 5 and have no headphone jack. The listed battery life is 3–5 hours per charge, with charging from the included case; the data does not specify laptop operating-system compatibility.
SZHTFX lists noise-suppression performance of up to 24 dB. COMPLY says its foam seal is designed to isolate outside noise, but no decibel figure is provided, so the two claims cannot be compared numerically.
The product information emphasizes sleep, compact size, and in-ear fit, but does not specify sweat resistance. If sweatproof use is essential, these details don’t establish that they meet the need.
