Both are Bluetooth headphones with low latency as the headline feature, but they solve very different problems. The C519M is a closed loop: a pre-paired headphone and USB-C transmitter that drops lag to under 40ms. The HomeSpot Neckband leans on Bluetooth 5.1 and the aptX Low Latency codec to keep audio and video close enough for casual gaming and video. One is built for a desk or a console. The other is built to move with you.
• Avantree C519M — biggest strength: The bundled USB-C adapter creates a private low-latency link rated under 40ms, plus 16-bit stereo chat quality that holds up while you talk and game at the same time.
• Avantree C519M — biggest trade-off: It's an over-ear headset tethered to its own dongle, so it doesn't work with a TV, Xbox One or PS3, and the built-in mic and buttons stop working in wired mode.
• HomeSpot Neckband — biggest strength: A flexible around-the-neck design with magnetic earbuds and three eartip sizes, supporting aptX Low Latency over standard Bluetooth 5.1.
• HomeSpot Neckband — biggest trade-off: Its low-latency mode depends on your source device supporting aptX Low Latency, so a phone that only offers SBC or AAC won't get the full benefit.
• Pick the Avantree C519M if you game or take long calls at a PC, Mac, Chromebook or console with a USB-C port.
• Pick the HomeSpot Neckband if you want something you can coil into a pocket for running, gym sessions and everyday phone listening.
• In my opinion, both are honest low-latency options — the deciding factor is whether you sit still or move around.
The C519M is the more specialized tool of the two, and it's proud of it. Avantree ships a headphone and a USB-C transmitter that are already paired out of the box, so you plug the dongle into a USB-C port, switch the headphones on, and you're running. No pairing menus, no driver installs. It works with PS5, Switch, Mac, PC, Chromebook and Linux machines that output audio over USB-C.
The engineering here is aimed squarely at latency and chat quality. The adapter-to-headphone link is rated at under 40ms of lag, which Avantree contrasts with roughly 220ms for standard Bluetooth. That's the difference between lip-sync that feels off and audio that simply matches the screen. The other piece is 16-bit stereo chat: the set is designed to avoid the audio-quality drop you normally get when a Bluetooth mic kicks in, so Discord chat and game audio can run together without one ruining the other. You also get up to 40 hours of playback per charge at 60% volume, with a 2-hour top-up over micro-USB.
Who should buy it? Anyone whose gaming or meeting life happens at a USB-C device and who is tired of fiddling with Bluetooth settings. The over-ear fit and 180g weight suit long sessions, and the 32-ohm dynamic drivers cover a 20Hz–20kHz range. Who should skip it? If your setup is a TV, an Xbox One or a PS3, this isn't the product — those aren't supported. If you want earbuds for the treadmill, the over-ear format and the dongle dependency will feel like baggage. Check the current price on Amazon before deciding, because the bundled transmitter is a big part of what you're paying for.
The HomeSpot JY100 takes the opposite approach: everything lives around your neck. The band is made from ABS+PC and contoured to sit lightly, and the earbuds are magnetic, so they snap together and coil up without tangling when you stuff them in a pocket or bag. Three eartip sizes are included, which matters more than people admit for in-ear comfort over a long run. Charging is over micro-USB and takes about 2 hours, with up to 20 hours of listening and 240 hours of standby per charge.
On the wireless side, you get Bluetooth 5.1, a 10-meter working range, and codec support spanning SBC, AAC, aptX and aptX Low Latency. That last one is the headline for this article's angle: aptX Low Latency is what keeps audio and video reasonably in step when you're watching a video or playing a game on a compatible source. The catch is compatibility — aptX LL has to be supported on the transmitting device too, so an iPhone, which doesn't offer it, won't deliver the same low-latency behavior. The 10mm bio-cellulose drivers and 16-ohm impedance are tuned for a lively, easy-to-drive sound, and Qualcomm CVC noise cancellation handles the mic side for calls.
Who should buy it? Runners, gym-goers, commuters and anyone who takes a lot of voice calls on a phone or Bluetooth laptop. The neckband format means you never lose an earbud, and the passive noise isolation helps in noisy environments. Who should skip it? If you want maximum lag reduction on a console or a desktop without worrying about codec support, the C519M's dedicated adapter is the more reliable answer. And note the neckband is not designed for swimming, only for sweat and light moisture you can wipe off.
• Best for the lowest possible latency → Avantree C519M. Its rated under-40ms link is created by the included adapter, not by hoping your source supports a codec.
• Best for gaming on a USB-C console or PC → Avantree C519M. PS5, Switch, Mac, PC, Chromebook and Linux are all in scope, with pre-paired plug-and-play setup.
• Best for talking while you play → Avantree C519M. The 16-bit stereo chat design is specifically built to avoid the quality drop during mic use.
• Best for battery life → Avantree C519M. Up to 40 hours versus up to 20 hours on the HomeSpot.
• Best for portability and tangle-free storage → HomeSpot Neckband. Magnetic earbuds and a flex-form neckband coil straight into a pocket.
• Best for running, gym and commuting → HomeSpot Neckband. The around-the-neck fit and passive noise isolation are built for motion.
• Best for phone calls and voice assistants → HomeSpot Neckband. Qualcomm CVC noise cancellation plus one-second access to Siri or Google Assistant.
• Best for iPhone users → HomeSpot Neckband. It pairs over standard Bluetooth 5.1 without needing the special adapter setup the C519M depends on.
• Best for over-ear comfort on long sessions → Avantree C519M. The 180g over-ear design avoids in-ear pressure over multi-hour use.
If I were buying for a desk, a console or long meeting days, I'd take the Avantree C519M. The pre-paired USB-C transmitter removes the guesswork from low latency, the under-40ms figure is the most concrete lag advantage in this comparison, and the 16-bit stereo chat plus 40-hour battery make it the better long-session tool. I'd pick the HomeSpot Neckband instead if my listening happens on the move — running, gym, commuting, calls — because no adapter can beat a neckband you can coil into a pocket. In my opinion, the C519M wins on latency and endurance; the JY100 wins on freedom and fit.
FAQ
do bluetooth headphones have latency
Yes. Standard Bluetooth audio typically carries noticeable lag — Avantree cites around 220ms as the baseline — which is why low-latency modes exist. Both the C519M and the HomeSpot Neckband address this, but in different ways.
You need low-latency support on both ends of the link. The C519M does this with its own paired USB-C transmitter, rated under 40ms. The HomeSpot Neckband relies on the aptX Low Latency codec, which must also be supported by your phone, tablet or laptop.
how to get low latency on bluetooth headphones
On the C519M, plug the adapter into a USB-C port, power on the headphones, and the low-latency link is active automatically. On the HomeSpot Neckband, you need a source device that supports aptX Low Latency, since devices limited to SBC or AAC won't unlock that mode.
how to get low latency on bluetooth headphones windows 11
For Windows 11, the C519M is the simpler path: the bundled USB-C adapter works with PC systems including Windows, so there's no codec hunting. With the HomeSpot Neckband, low latency depends on your Windows Bluetooth adapter and its codec support, so results vary by machine.
