If you want a stable, no-nonsense radio link with a charging dock, digital and analog inputs, and a wired backup for late-night TV, choose SEREONIC WH100; if you need a lower-latency connection, a far longer battery and a plug-and-play path into a smart TV, choose eppfun Headphones. That's the short version after reading both spec sheets side by side. And because this is usually the page people land on while searching for the best bluetooth headphones for side sleepers, let me say the honest thing up front: neither of these is that product. Both are over-ear headsets built to sit on your ears, not flat enough to press into a pillow. What they actually do well is carry TV audio to one person in bed at 2 a.m. without waking the house — and they go about it in two very different ways.
• SEREONIC WH100, biggest strength: a UHF/RF wireless link with a three-channel selector, a dock that charges the headset, and a transmitter that takes both 3.5mm analog and optical/coaxial digital audio — plus a 3.5mm jack so the headphones still work wired.
• SEREONIC WH100, biggest trade-off: 8 hours of listening at 50% volume with about 3 hours to recharge, and no noise control at all.
• eppfun Headphones, biggest strength: two wireless modes (2.4G and Bluetooth 5.3), a stated latency under 27ms, 50 hours of battery, and an LED display on the charging base that shows what's connected.
• eppfun Headphones, biggest trade-off: more modes and more cables to get right — the plug-and-play promise depends on matching the transmitter to the outputs your TV actually has.
• Who each pick is for: the SEREONIC suits one viewer who wants a set-and-forget radio link with a wired safety net; the eppfun suits a heavier viewer, a multi-person household, or an older parent who needs a status display instead of a pairing menu.
The WH100 is a TV-listening headset first and foremost. Its wireless path is UHF/RF, not Bluetooth pairing — you flip through three channel positions to dodge interference, and the transmitter stays put next to the TV. That transmitter is more flexible than you'd expect for a product aimed at simple operation: it accepts 3.5mm analog audio as well as optical and coaxial digital, so it can hang off an older set, a newer set, or a cable box. Charging happens two ways, either by dropping the headset on the dock or by plugging a USB cable directly into the headphones, and there's a 3.5mm headphone jack so the set can be used wired if you'd rather not rely on the radio link.

Buy it if you're one person, one TV, and you want no menus and no pairing: sit down, switch on, adjust volume, done. The wired jack is a genuinely useful fallback when the battery runs down mid-film. Skip it if you watch for more than eight hours at a stretch, want isolation from household noise, or want a Bluetooth headphone for your phone — the product info does list a Bluetooth 4 entry, but the system as described is RF/UHF with channel selection, so treat it as a TV transmitter headset rather than a general-purpose wireless headphone. And if you're hunting the best lightweight bone conduction headphones for side sleepers, keep looking: this is an over-ear cup design and there's nothing stealthy about it against a pillow.
The eppfun set is the more feature-dense of the two. It runs two wireless modes — 2.4G for TV use and Bluetooth 5.3 for everything else — and the 2.4G link is quoted at under 27ms of latency, which is the number that decides whether lips and dialogue stay together on screen. The charging base doubles as a transmitter and carries an LED display showing connection and charging status, which is a small thing that matters a lot if the person using it doesn't want to troubleshoot. Inputs cover optical, 3.5mm AUX and RCA. If your TV is a smart set with USB-C, a single Type-C cable can handle it with no settings to change.
Battery is the headline: up to 50 hours of continuous use on a charge, with the headset topping up whenever it's set back on the base. Pairing is automatic when you lift the headphones off, so there's no re-pairing dance every evening. eppfun also documents multi-listener use — two earphones in Bluetooth mode, and up to 256 devices in 2.4G mode — which is unusually generous for a TV headphone and makes it the better fit for couples or a room full of people. The set is over-ear in black and lists sound isolation, so it does more to shut out the room than the SEREONIC does.
Buy it if you watch a lot, want the audio to stay locked to the picture during sport and fast action, or you're setting someone older up with something that shows its own status lights. Skip it if you want a wired fallback — there's no headphone jack listed for the eppfun set, so when the battery finally empties you're charging rather than plugging in. Skip it too if your TV has no free optical, AUX or RCA output and isn't USB-C capable, because then the plug-and-play story gets harder.
Side-by-Side: Which Should You Choose?
• Longest battery life → eppfun Headphones. Up to 50 hours versus 8 hours at 50% volume on the SEREONIC. This isn't close.
• Lowest audio delay for sport, action and games → eppfun Headphones. The sub-27ms 2.4G figure is the more convincing of the two latency claims, and it's the one I'd want if you're also chasing the best gaming headphones for side sleepers and only care about sync.
• Simplest one-person RF setup with both digital and analog inputs → SEREONIC WH100. Three channels, a dock, no pairing, no display to interpret.
• Two or more people watching at once → eppfun Headphones. Its documented multi-headphone support beats a single-headset radio link.
• Fastest hookup to a smart TV → eppfun Headphones. A single USB-C cable, no settings, according to the manufacturer's own description.
• Lightest mental load for a gift → eppfun Headphones. The LED base tells the user what's happening; the SEREONIC asks them to remember which channel they used.
• Actual side sleeping in bed → neither. Both are over-ear cups that sit proud of your head. If lying on your side is the priority, no spec on either sheet changes that, and a flat or bone-conduction design is the right category instead.
I'd buy the eppfun Headphones. Fifty hours against eight, a 2.4G link quoted under 27ms, Bluetooth 5.3 for phone listening, a base that reports its own status and multi-headphone support add up to a set that covers more evenings with less babysitting — and the battery gap alone is decisive for anyone who doesn't want a nightly charging ritual. The SEREONIC WH100 is the one I'd pick in a narrower case: one viewer, one TV, and a strong preference for a plain radio link plus a wired jack as insurance. For side sleepers specifically, I'd treat either of these as a TV-audio purchase rather than a sleep-comfort one — excellent for keeping the volume off the room, not designed to be slept on.
FAQ
No. Both are over-ear designs with cups that protrude from the head, so lying on your side will press them into the pillow and shift them off your ears. If side sleeping is the real requirement, look at flat or bone-conduction style options; use these for TV audio while sitting or propped up.
The eppfun Headphones, by a wide margin — up to 50 hours per charge versus 8 hours at 50% volume on the SEREONIC WH100, which takes about 3 hours to recharge on its dock. The eppfun also tops up whenever it's set back on its base.
No. Both transmitters accept standard TV audio outputs — 3.5mm, optical and RCA on the eppfun, 3.5mm plus optical/coaxial on the SEREONIC. The USB-C single-cable shortcut is a bonus that only applies if your TV supports it.
Prices move around, so there's no figure here to rely on — check the current price on Amazon for both before you commit. On features alone, the eppfun carries more of what most people want, while the SEREONIC justifies itself with simplicity and a wired fallback.
