If you want workout-ready replacement foam tips that grip your compatible earbuds and help isolate outside noise, choose COMPLY Memory Foam Replacement; if you need discreet, self-contained earbuds for sleep, choose Hulaed Invisible Sleep Headphones. For a workout, COMPLY is the more relevant pick—but only if you already own compatible earbuds.
COMPLY Memory Foam Replacement vs Hulaed Invisible Sleep Headphones at a Glance
• COMPLY’s strength: Body-heat-activated foam is designed to mold to your ear and grip during workouts. Trade-off: These are replacement tips, not earbuds, and compatibility is limited.
• Hulaed’s strength: Tiny wireless earbuds are designed for sleeping, including on your side, and include a sleep mode. Trade-off: Their stated continuous listening time is more than six hours, so they are sleep-focused rather than built around long sessions.
• Choose COMPLY if you own compatible earbuds and want a foam fit intended to stay secure during movement.
• Choose Hulaed if you want a compact, standalone wireless pair for sleep and everyday listening.
COMPLY Memory Foam Replacement is a set of foam ear tips, not a new pair of headphones. The foam responds to body heat and molds to the ear, with a design intended to provide a secure fit and reduce outside noise. The stated compatibility includes Powerbeats Pro, Powerbeats, and Flex; the product information also explicitly says it does not fit Beats Studio Buds. Check your exact earbud model before choosing it.
For workout use, the appeal is practical: the tips are designed to grip better than silicone and help keep compatible earbuds in place during running, exercise, and daily activity. A closer seal may also support bass and clarity by reducing outside sound. That could make COMPLY a useful option for someone searching for the best sports earbuds for workout—provided they already have compatible earbuds. It is not a complete audio setup by itself.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-23 · 6 min read · Independent comparison
Hulaed is a complete pair of small wireless earbuds built around sleep. Its silicone ear tips and low-profile design are intended to be comfortable for side sleepers, including during extended wear. Sleep mode disables the earbud buttons so that accidental touches are less likely to interrupt playback; the phone remains the way to control them in that mode.
The stated battery life is six hours, while the product description says continuous use can exceed six hours. Bluetooth connectivity allows pairing with a smartphone without a cable, and the earbuds include a noise-reduction microphone. An IPX6 waterproof claim also makes them relevant to some sports and water activities, though their positioning and design are primarily sleep-oriented.
I’d consider Hulaed if you want an all-in-one wireless option for bedtime, quiet listening, or a small earbud to carry around. I would not choose it as a replacement tip for existing earbuds, because it is a separate headphone product. Nor would I assume its sleep-first design makes it the right workout choice for everyone: the available information does not describe a dedicated workout fit feature in the same way COMPLY describes its foam tips gripping during movement.
• Best fit for workout movement with compatible earbuds → COMPLY. Its foam tips are designed to grip and stay in place during running and workouts.
• Best for sleeping on your side → Hulaed. The low-profile earbuds and soft silicone tips are specifically aimed at sleep comfort.
• Best if you already own compatible Powerbeats earbuds → COMPLY. It replaces the ear tips rather than asking you to buy another complete pair.
• Best if you need complete wireless earbuds → Hulaed. Bluetooth earbuds and a built-in microphone are part of the product.
• Best for reducing outside noise through a foam seal → COMPLY. The tips are designed to isolate noise and support a closer fit.
• Best for controlling playback without touching the earbuds at bedtime → Hulaed. Sleep mode disables their buttons, leaving the phone as the control method.
• Best for someone comparing “hifi stereo wireless earbuds for workout” → Hulaed is the complete wireless product, but neither sheet establishes a formal hi-fi standard or workout-specific audio test. COMPLY can only be used with compatible earbuds.
• Best if your search is “best noise canceling gaming headphones for workout” → neither is a direct match. COMPLY is a replacement tip, and Hulaed is described as a sleep earbud; neither is identified as a gaming headset or active noise-canceling headphone.
The choice is less about picking a universal winner and more about matching the product type to the job. If you want to improve the fit of earbuds you already own, COMPLY is the relevant option. If you want earbuds in the box and your main use is listening while you sleep, Hulaed is the straightforward fit.
My Verdict
For a workout, I’d choose COMPLY Memory Foam Replacement if I already owned one of the compatible earbuds listed. Its foam grip and noise-isolating seal are more directly suited to movement than Hulaed’s sleep-first design.
If I needed a complete pair for bedtime instead, I’d choose Hulaed for its compact form and sleep mode. My overall pick for workout use is COMPLY, with compatibility as the deciding condition.
No. They are replacement foam tips for compatible earbuds, including Powerbeats Pro, Powerbeats, and Flex. Check the exact model before buying; the listing specifically excludes Beats Studio Buds.
They are designed with side sleeping in mind, using small earbuds and soft silicone tips. Their sleep mode disables the earbud buttons, so playback controls are handled through the phone.
COMPLY is the more workout-focused choice if you already have compatible earbuds, because its foam tips are designed to grip during exercise. Hulaed is a complete wireless pair, but its key design emphasis is sleep.
The provided product information describes sound isolation or noise reduction, not active noise cancellation. COMPLY’s foam is intended to create a seal that helps reduce outside noise; Hulaed also lists sound isolation.
