How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear neckband you can wear through a sweaty workout and still hear traffic around you, choose GZLMMY Neckband Earphones; if you need a TV companion that makes movie dialogue clear for a hard-of-hearing parent, choose Holdsound Headphones.
These two look like they compete. They don't. One is a sporty, in-ear neckband built for movement and ambient awareness. The other is an over-ear wireless TV headset built for one job: letting you hear the television clearly without cranking the volume on everyone else in the room. If you're torn between them, the deciding question isn't which is "better" — it's what you'll actually plug them into.
• GZLMMY Neckband Earphones — biggest strength: an around-the-neck, in-ear design with active noise cancellation, ear-return (ambient) audio, and roughly 18 hours of rated playback on a single charge, with a digital battery display so you can see where you stand.
• GZLMMY Neckband Earphones — biggest trade-off: it's a general-purpose Bluetooth earbud, not a TV product — no transmitter, no wired TV input, and its noise cancelling works against you if you wanted to hear the room.
• Holdsound Headphones — biggest strength: over-ear comfort with 40 hours of rated battery, a factory-paired USB transmitter, low latency under 40 ms, and a 50 m (165 ft) wireless range for TV watching.
• Holdsound Headphones — biggest trade-off: it's wired to a TV ecosystem. It needs an optical or 3.5 mm AUX output on your TV and does not support direct Bluetooth pairing to other devices.
• Buy GZLMMY if you want one pair of earbuds for the gym, runs, calls and karaoke-style fun.
• Buy Holdsound if you're buying for yourself or an older relative who wants TV dialogue loud and clear without disturbing anyone else.
The GZLMMY YG07 is a neckband-style wireless earphone. The band rests around your neck, the earpieces sit in your ears, and the whole unit weighs about 60 g with a total length of roughly 45 cm. That shape matters more than it sounds: a neckband keeps the electronics and battery off your ears, so nothing pulls on your ear canals the way a heavy true-wireless bud can. For running, cycling, gym sessions and long commutes, that's a genuinely comfortable way to carry audio.
The audio hardware is a dynamic driver with 16 ohm impedance and a 20 Hz – 20,000 Hz frequency range — a standard full-range spec that covers music, podcasts and game audio without surprises. The body is ABS plastic, listed as life-waterproof, so sweat and light rain are the intended environment rather than swimming. GZLMMY also advertises karaoke and live-streaming support, so if you record or broadcast casually, that's a use case the manufacturer calls out.
Who should buy it: anyone who wants one pair of wireless earphones for training, commuting and casual listening, and who values being able to hear the world when they need to. Who should skip it: anyone shopping for a TV set. There's no transmitter, no optical or 3.5 mm audio input, and no docking station — it connects to devices over Bluetooth only, so a television without Bluetooth audio out is not its job.
Holdsound Headphones: Who It's For
The Holdsound BKM700 is a different animal entirely: over-ear wireless headphones designed around television. The package includes a USB transmitter, an optical cable, a 3.5 mm cable, a Type-C charging cable and a manual. The headphones and transmitter are paired at the factory, so setup is essentially "plug the transmitter into the TV, power both on, wait about three seconds." That's the entire pitch, and for the person it's aimed at, it's the right one.
The spec sheet tells you who that is. The BKM700 offers 40 hours of rated battery life, soft protein-leather earcups and an adjustable headband — the combination you want for a four-hour movie night or an all-day sports marathon. Wireless range is rated up to 50 m (165 ft), so the signal is meant to hold through walls and furniture. Latency is rated under 40 ms, which is the number that matters for TV: audio stays locked to lips, so you don't get that laggy, out-of-sync feeling that ruins dialogue-heavy drama. And dialogue clarity is the headline feature — the stated goal is hearing every word without turning your living room into a cinema for the neighbours.
Two connection options are supported: optical (TOSLINK) and 3.5 mm AUX, and the manufacturer states it works with roughly 99% of TVs. Read that carefully, because it's the one hard requirement: your TV or source device must have an optical or 3.5 mm audio output. Direct Bluetooth pairing to other devices is not supported — this is a TV-first product, not a general-purpose headphone. Noise control is sound isolation rather than active cancellation.
Who should buy it: seniors and anyone with mild-to-moderate hearing difficulty who wants TV dialogue at their own volume; partners of people who watch late; and anyone tired of fiddling with pairing menus. Who should skip it: anyone who wants headphones for a phone, gym or commute — that's not what this is built for.
• Best for workouts and running → GZLMMY Neckband Earphones. Neckband shape, in-ear fit, life-waterproof build, 60 g total weight.
• Best for TV dialogue and late-night viewing → Holdsound Headphones. Over-ear cups, dialogue-forward tuning, isolation so the room stays quiet.
• Best battery life → Holdsound Headphones. 40 hours rated versus roughly 18 hours on the GZLMMY.
• Best for staying aware of your surroundings → GZLMMY Neckband Earphones. The ear-return function pipes ambient sound back in; that's the opposite of what a TV headset is for.
• Best for fast, fuss-free setup → Holdsound Headphones. Pre-paired at the factory; power on and it connects in about three seconds.
• Best for use with a phone, tablet or laptop → GZLMMY Neckband Earphones. Standard Bluetooth connection, no transmitter or TV port required.
• Best for gifting to an older parent → Holdsound Headphones. Over-ear comfort, simple button volume control, and a design purpose-built for TV.
• Best for gaming and casual streaming → GZLMMY Neckband Earphones. Sub-40 ms latency is the Holdsound's strength for TV, but the GZLMMY is the one that connects to your console, PC or phone over Bluetooth.
If I had to pick one, I'd pick based on the room, not the spec sheet. For me, the Holdsound Headphones win as the more specialised, more useful product — 40 hours of battery, over-ear comfort and a factory-paired transmitter solve a real, specific problem that generic earbuds don't. But I'd only recommend it to someone with a TV that has an optical or 3.5 mm audio out. If your life is gym bags, runs and phone calls, I'd take the GZLMMY Neckband Earphones instead: the neckband fit, ambient ear-return and 18-hour battery are exactly right for that. Check the current price on Amazon for whichever one matches your setup before you commit.
FAQ
Not as a standard Bluetooth headphone. Holdsound states direct Bluetooth connection to other devices is not supported — it works with the supplied transmitter plugged into a TV or device with optical or 3.5 mm output.
Holdsound, by a wide margin: 40 hours rated versus about 18 hours on the GZLMMY. The GZLMMY charges in roughly 2 hours over USB and adds a digital power display.
They include Active Noise Cancellation, but they also have an ear-return function that lets surrounding sound back in — useful for running or cycling. Holdsound relies on passive sound isolation from its over-ear earcups instead.
Then neither Holdsound's transmitter route works — Holdsound explicitly requires an optical (TOSLINK) or 3.5 mm AUX output. In that case the GZLMMY is the more practical option if your TV supports Bluetooth audio.
