If you want open-ear headphones with phone-free underwater playback for TV watching between workouts, choose LYPERTEK SoundFree S30; if you need over-ear coverage, active noise cancelling, and long stated battery life for TV watching, choose Monster Harmonic N22. For most people choosing specifically for TV, I’d lean toward the Monster: its over-ear design and noise-control modes fit that use more naturally, while the LYPERTEK is built around swimming and active listening.
The main trade-off is clear: the S30’s waterproof, open-ear design is unusually useful around water, but it is not an over-ear TV headphone. The N22 is the more conventional home-listening option, though its published information does not specify a dedicated TV connection or a low-latency figure.

• LYPERTEK SoundFree S30 — biggest strength: IP68 waterproof protection, a stated TÜV Rheinland 10m certification, and 32GB of built-in MP3 storage for swimming without a phone. Trade-off: its open-ear bone-conduction design is aimed at exercise, not immersive television listening.
• Monster Harmonic N22 — biggest strength: over-ear fit, active noise cancelling, transparency and standard sound modes, and up to 110 hours of listening with ANC off. Trade-off: its specs do not state TV-specific pairing support or a latency figure.
• Choose the SoundFree S30 if you want one headset for swimming and other workouts, especially when Bluetooth cannot reach your playback device.
• Choose the Harmonic N22 if you want a conventional over-ear headphone for home, travel, or work listening, with noise-control modes and long stated battery life.
The SoundFree S30 is the specialized pick here. Its open-ear bone-conduction design keeps the ear canals uncovered, and its IP68 waterproof protection is intended for swimming, rain, and intense workouts. The stated TÜV Rheinland 10m certification and built-in 32GB MP3 player make its strongest use case easy to identify: pool sessions where a phone and a Bluetooth connection are not practical. The storage is listed as enough for more than 8,000 songs.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

Its 23g titanium memory-wire frame with a soft silicone coating is designed to sit securely during movement. Bluetooth 6.0 supports ordinary wireless listening, while the three EQ modes let the listener choose among sound settings. A rear safety LED, magnetic charging, and dual-mic ENC for calls add practical workout features. The listed Bluetooth range is 10 meters.
That distinction matters for anyone searching for the best on ear headphones for tv watching. The S30 isn’t an on-ear or over-ear model; it is an open-ear sports headset. Its waterproofing and onboard music storage are compelling for their intended purpose, but they don’t make it the natural choice for sitting down with a television.
The Harmonic N22 is the more familiar headphone design for home listening. It uses an over-ear fit and 40mm dynamic drivers, with active noise cancelling and three listening modes: ANC, transparency, and standard sound. That gives it a more plausible role for television in a noisy room or for listening when you’d rather have your ears covered. The supplied information describes the sound as stereo with bass, mids, and highs, but it does not establish how it performs with any particular TV.
Battery life is one of its clearest selling points on paper. Monster states up to 110 hours with ANC off, and says a 10-minute quick charge supports five hours of playback. The product information separately lists an average battery life of 60 hours and a two-hour charging time, so I would treat the maximum figure as a stated best-case mode rather than assume every listening setup will reach it. Bluetooth 6.0 is highlighted in the feature description, while the product information lists Bluetooth 5.4; that discrepancy is worth checking against the specific listing before buying.
The N22 is the better fit if you want over-ear headphones for films, travel, work, or everyday wireless listening, and you value noise-control options and a long claimed runtime. Its memory-foam cushions, adjustable headband, and foldable structure are intended for extended wear and portability. I would not choose it on the assumption that it will automatically pair with every television or avoid audio delay: the supplied details do not specify TV compatibility, a dedicated transmitter, or a latency measurement.
It is also the closer match for shoppers looking for multipoint Bluetooth earbuds for TV watching, though the N22 is not earbuds. Its description mentions dual-device connection, which may suit someone switching between two devices, but it does not explain the pairing behavior in detail. If multipoint support is essential, confirm what the specific device and TV combination supports.
Side-by-Side: Which Should You Choose?
• Best for conventional over-ear TV listening → Monster Harmonic N22. Its over-ear cushions and headband are better aligned with sitting through a show than the S30’s open-ear sports frame.
• Best for keeping ears uncovered → LYPERTEK SoundFree S30. Bone conduction leaves the ears open, a useful design choice for workouts when awareness of surrounding sound matters.
• Best for noise-control modes → Monster Harmonic N22. It offers ANC, transparency, and standard sound modes; the S30’s listed noise feature is environmental noise cancellation for calls.
• Best for stated maximum battery life → Monster Harmonic N22. Monster lists up to 110 hours with ANC off, while the S30’s supplied information does not give a battery-runtime figure.
• Best for a phone-free pool session → LYPERTEK SoundFree S30. Its built-in MP3 player stores music locally for use where Bluetooth signals cannot work underwater.
• Best for a foldable travel design → Monster Harmonic N22. Its described structure folds, while no folding design is listed for the S30.
• Best rotatable ear cups headphone for TV watching → neither is confirmed by the supplied specs. The N22 is over-ear, but no rotatable ear-cup feature is specified; don’t buy it expecting that detail.
For television use, I’d first check how your TV sends audio. The N22 is wireless and lists Bluetooth connectivity, but the provided details do not confirm a TV-specific setup, compatibility with a particular television, or low latency. The S30 also connects by Bluetooth for ordinary listening, but its strongest playback feature is local MP3 storage for swimming. Neither spec sheet gives enough detail to promise lip-sync performance with every TV.
The N22’s active noise cancelling may help reduce ambient distractions, while its transparency mode is designed to let surrounding sounds through. Those modes speak to general listening preferences, not to sound isolation from the television itself. The S30’s open-ear fit takes the opposite approach: it leaves the ears uncovered, which can be useful when awareness matters but is less suited to blocking household noise.
My Verdict
I’d choose the LYPERTEK SoundFree S30 instead if swimming were the priority; its waterproof design and onboard MP3 storage solve a specific problem the Monster does not. For TV watching, though, the N22 is my pick.
The Harmonic N22 is the more natural fit because it is an over-ear headphone with ANC, transparency, and standard listening modes. The S30 is an open-ear bone-conduction model designed mainly for swimming and workouts.
The S30 is described as IP68 waterproof and as carrying TÜV Rheinland 10m certification. It also has built-in MP3 storage, so it can play stored music without relying on Bluetooth underwater.
The supplied specifications list wireless Bluetooth connectivity but do not name specific TVs or confirm universal compatibility. Check your television’s Bluetooth audio support before choosing it, particularly if you need a particular connection method.
Monster states up to 110 hours for the N22 with ANC off, while its product information also lists an average battery life of 60 hours. No battery-runtime figure is provided for the SoundFree S30, so the available details do not support a direct runtime comparison.
