How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want earbuds that stay locked on your ears through hard gym sessions and marathon training blocks, choose FK Trading Samsung Galaxy Note10+; if you need earbuds you can wear all night, on your side, without pressure points, choose Hulaed Invisible Sleep Headphones.
• FK Trading Samsung Galaxy Note10+ — biggest strength: a secure ear-hook build with Bluetooth 5.3, four microphones for calls, and 48 hours of total playback with the 500mAh charging case.
• FK Trading Samsung Galaxy Note10+ — biggest trade-off: it's a sport earbud first. It's lightweight and in-ear, but it isn't specifically shaped for side sleepers, so it's not the one I'd pick for all-night wear.
• Hulaed Invisible Sleep Headphones — biggest strength: a discreet, small in-ear design with skin-soft silicone tips, 6–8 hours of continuous use, and an open-ear feel that doesn't jam into the ear canal.
• Hulaed Invisible Sleep Headphones — biggest trade-off: battery life is 6 hours (and up to 8 hours of continuous use per the specs), with no charging case mentioned — so longer sessions mean you need a charging routine.
• Who each is for: FK Trading for workouts, running, gym, and calls on the move; Hulaed for sleep, side sleeping, driving, hiking, and cycling.
Think of this as the earbud you grab when you're moving. The ear-hook design is the headline here: soft, flexible hooks that hold the bud in place even during strenuous sports, plus three sizes of silicone eartips (S/M/L) so you can actually dial in the fit. If you've ever had a bud pop out mid-sprint, that's the problem this design is aimed at. The hooks also mean the fit isn't relying purely on the seal inside your ear canal, which is a real comfort win on long runs.
Battery is the other place it stands out. You get 9 hours of playback from the buds, and the 500mAh charging case pushes total playtime to 48 hours. The case charges over USB-C in about 1.5 hours, and there's an LED display so you can see the state of charge instead of guessing. For someone who trains most days and hates plugging things in, that's a sensible setup.
Who should buy it: runners, gym-goers, cyclists, anyone who wants a secure hook fit, long battery life, and clear calls during exercise. Who should skip it: if your main use is falling asleep on your side, this isn't shaped for that job — look at the Hulaed instead.
Hulaed Invisible Sleep Headphones: Who It's For
This one is built around a single problem: sleeping with earbuds in. The buds are described as the smallest type, sitting discreetly in your ears — small enough to hide at work, and small enough that lying on your side doesn't press them into your head. The eartips and caps use a skin-soft silicone, and the design deliberately avoids pushing deep into the ear canal, so even after a full night your ears shouldn't feel sore from pressure. If you toss and turn, that's the scenario this product is designed for.
Battery is rated at 6 hours average, with up to 6–8 hours of continuous use. That covers a normal night's sleep for most people, though heavy sleepers or anyone using them for long daytime stretches will want to charge daily. There's no charging case mentioned in the specs, so plan around a nightly top-up rather than a multi-day reserve.
On the audio side, the Hulaed uses a planar magnetic driver with 16 ohm impedance — an unusual choice at this size, and one that typically points toward detailed, controlled sound rather than boomy bass. It's paired with "whale cavity" stereo surround processing and a built-in noise reduction microphone for calls. Bluetooth 5.3 keeps the connection stable with low delay, and the open-ear approach plus sound isolation means you still hear your surroundings — useful for driving, hiking, and cycling, where full isolation can be a safety issue rather than a feature.
Who should buy it: side sleepers, people who want discreet buds at work, and anyone who needs to stay aware of their surroundings while driving or riding. Who should skip it: if you want maximum battery life, a charging case, and a fit that's locked down for sprinting, the FK Trading pair is the better match.
• Best for hard workouts and running → FK Trading Samsung Galaxy Note10+. The ear hooks plus three eartip sizes are designed to keep the bud planted when you're moving.
• Best for sleep and side sleeping → Hulaed Invisible Sleep Headphones. Skin-soft silicone and a shallow, in-ear fit built specifically for all-night wear.
• Best for battery life → FK Trading Samsung Galaxy Note10+. 9 hours in the buds and 48 hours total with the case, versus 6 hours on the Hulaed.
• Best for staying aware of traffic and surroundings → Hulaed Invisible Sleep Headphones. The open-ear, sound-isolation approach leaves you more aware than a deep-sealed sport bud.
• Best for calls during exercise → FK Trading Samsung Galaxy Note10+. Four microphones with environmental noise cancelling are the more call-focused setup.
• Best for discreet, invisible wear at work → Hulaed Invisible Sleep Headphones. Small buds that sit quietly in your ears and can be worn on their own.
• Best for charging convenience → FK Trading Samsung Galaxy Note10+. USB-C quick charge in about 1.5 hours plus a visible LED charge display.
• Best for a single bud you can use alone → Hulaed Invisible Sleep Headphones. Each bud works independently, which suits one-ear listening while driving or working.
In my opinion, most people should start with the FK Trading Samsung Galaxy Note10+. The ear-hook fit, 48-hour total playtime, USB-C charging with an LED display, and four-mic call setup make it the more versatile everyday earbud — it handles the gym, runs, calls, and casual listening without a weak spot.
I'd only steer you to the Hulaed Invisible Sleep Headphones if sleep is the actual job. If you're a side sleeper, or you want something invisible at work that you can wear for hours without ear soreness, its skin-soft silicone and shallow fit are the whole point, and that's worth the shorter 6-hour battery. Check the current price on Amazon before deciding, since both sit in different value brackets depending on the day.
