If you want the ear-hook design for a secure fit during activity, choose Rythflo Headphones; if you need a detachable neckband and included multiple eartip sizes, choose Rythflo Headphones. For side sleepers comparing under 150 neckband headphones, I’d focus less on the shared headline battery figure and more on the fit and controls each version describes.
Rythflo Headphones vs Rythflo Headphones at a Glance
• Rythflo Headphones (B0CRTHJ9WD): Ear wings and hooks are intended to help hold the in-ear buds in place; trade-off: the listed design includes protruding hooks, which may not suit someone pressing an ear against a pillow.
• Rythflo Headphones (B0C3C6S3H5): A detachable neckband and nine listed pairs of eartips offer more fit options; trade-off: the sheet gives no ear-hook or ear-wing feature for added retention.
• Both list a 13 mm driver, up to 150 hours of playtime, IPX7 water and sweat resistance, and no noise control.
• The first version lists Bluetooth 5.2 in its product information, while its feature description says 5.3; the second lists Bluetooth 5.3. That inconsistency makes the first version’s Bluetooth generation less clear.
• Choose the first if you want ear hooks and ear wings; choose the second if a detachable neckband and several eartip sizes matter more.
The first Rythflo version is the more activity-focused fit on paper. Its in-ear buds have ear hooks and ear wings, described as helping keep them secure during intense movement. That could appeal to someone who wants earbuds that stay put on a walk or workout, rather than a small earbud that relies only on its tip. The sheet also lists a 13 mm driver, a 20 Hz–20,000 Hz frequency range, and media controls.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Its battery claim is up to 150 hours, with the feature description adding that a 10-minute charge can provide 15 hours of listening. It also lists IPX7 water and sweat resistance. Those details suit a buyer who wants infrequent charging and a design intended for active use. Bluetooth is less straightforward: the feature list says 5.3, but the product information says 5.2. I would not treat the version as settled without checking the product details before buying.
For side sleepers, the hooks are the central trade-off. If minimizing pressure around the outer ear is your priority, this description does not give enough reason to assume the hooked design will be comfortable. I’d skip it for sleep if you know ear hooks bother you.
The second Rythflo version has a detachable neckband and comes with three pairs each of small, medium, and large eartips. That gives a buyer more sizes to try when looking for a stable in-ear fit. The listed controls are buttons, and the product information specifies Bluetooth 5.3, a 10-meter Bluetooth range, and a 13 mm dynamic driver. Like the first version, it lists a 20 Hz–20,000 Hz frequency range and no noise control.
Its stated battery life is up to 150 hours, and the feature description says a 10-minute charge can provide 15 hours of listening. The sheet also lists IPX7 water and sweat resistance. A detachable neckband may appeal to someone who wants the two earbuds joined when not wearing them, but the information does not explain exactly how it rests around the neck or whether it is more comfortable for sleep.
That uncertainty matters for side sleepers. The eartip choices may help with fit, but no low-profile shape or sleep-specific design is stated. The product information describes rounded tips rather than ear hooks, which may be preferable to a buyer who wants to avoid hooks, though it does not prove the earbuds will feel unobtrusive against a pillow. I’d favor this version if the detachable neckband and included tip sizes are useful in daily wear, not on the assumption that it is automatically made for sleeping.
Side-by-Side: Which Should You Choose?
• Best for a retention-focused in-ear fit during movement → Rythflo Headphones (B0CRTHJ9WD). It specifically lists ear hooks and ear wings intended to help keep the buds secure.
• Best for a detachable neckband → Rythflo Headphones (B0C3C6S3H5). The included neckband is described as detachable.
• Best for button controls → Rythflo Headphones (B0C3C6S3H5). Its sheet specifies button control; the first lists media control and identifies a touch controller.
• Best for stated Bluetooth version clarity → Rythflo Headphones (B0C3C6S3H5). Its product information says Bluetooth 5.3, while the first version’s information conflicts between 5.2 and 5.3.
• Best for the shared long-playtime claim → Tie. Both list up to 150 hours and say a 10-minute charge can provide 15 hours of listening.
• Best for stated water and sweat resistance → Tie. Both list IPX7 resistance.
• Best for sleep-related certainty → Neither. Neither sheet confirms a low-profile fit, pillow comfort, or a sleep-focused design.
In my opinion, I’d choose the second Rythflo version for everyday use because its detachable neckband and several eartip sizes give it the more flexible setup. For side sleepers, though, I would not call either a clear sleep pick: the available details do not establish pillow comfort. If I were buying specifically for side sleeping, I’d prioritize a confirmed low-profile design over either product’s long battery claim.
Neither product sheet confirms that its earbuds are low-profile or comfortable when pressed against a pillow. The first lists ear hooks and ear wings; the second lists rounded tips and a detachable neckband. Fit preference may help narrow the choice, but the data does not prove either is suitable for side sleeping.
Do both Rythflo neckband headphones have the same battery life?
Both list up to 150 hours of playtime. Their feature descriptions also state that a 10-minute charge can provide 15 hours of listening. These are listed specifications, not a guarantee that every listening pattern will produce the same result.
The second version specifies button control. The first lists media control and identifies a touch controller. If you prefer physical buttons, the second has the clearer match in the product information; neither sheet provides enough detail to compare every control function.
No: both are described as in-ear headphones, not open-ear earbuds. Both list IPX7 water and sweat resistance, but that does not make them open-ear designs or establish comfort for sleeping. Likewise, someone searching for the best touch control earphones for side sleepers should note that the second version lists buttons, while the first identifies touch control.
