If you want a wireless, sweat-resistant neckband you can wear through workouts, commutes and long calls, choose WAVEFUN Neckband; if you need wired in-ear monitors with a replaceable cable and a tuning aimed at music lovers and gamers, choose keephifi KZ EDX Pro.
• WAVEFUN Neckband — biggest strength: a flexible neckband with Bluetooth 5.3, up to 12 hours of playtime, IPX5 sweat resistance and genuinely fast charging (15 minutes gets you about 4 hours of listening).
• WAVEFUN Neckband — biggest trade-off: it's a wireless consumer headset with no wired fallback and no noise cancellation, so a dead battery means silence until you charge it.
• keephifi KZ EDX Pro — biggest strength: a wired dual-magnetic dynamic driver IEM with a 5N OFC flat cable, a 0.75 mm 2-pin connector that can be swapped for an upgraded cable, and a tuning built around deep, dense low frequencies.
• keephifi KZ EDX Pro — biggest trade-off: it's wired, has no battery, and it ships with a single pair of ear tips in the current packaging, so there's no wireless freedom and no spare tips in the box.
• Pick the WAVEFUN Neckband if you want wireless convenience for the gym, calls and video.
• Pick the KZ EDX Pro if you care about sound quality first and don't mind a cable.
The WAVEFUN Neckband is built around convenience. The band sits around your neck instead of relying on a case, the two earpieces are magnetic so they click together when you're not listening, and everything runs over Bluetooth 5.3 with a 10-meter range. That matters more than it sounds: you can leave your phone on a bench or in a bag and keep listening while you move around. It uses SBC and AAC codecs with a tuning that leans on bass, and the 10 mm dynamic driver with 32 ohm impedance is a normal, easy-to-drive setup for a phone.
The feature list is unusually practical for this category. Fast charging is the standout — about 15 minutes of charging gives you roughly 4 hours of playback, and a full charge takes around 45 minutes for a claimed 12 hours of use. An IPX5 rating covers sweat and splashes, so running, cycling, hiking or a gym session won't kill it. There's also a gaming mode you trigger by holding volume up and down together for two seconds, which drops latency down to about 45 ms — useful for mobile games and for watching YouTube, TikTok or livestreams without the audio drifting behind the picture. And there's a group mode: triple-click the power button on each earbud and they sync into a shared TWS pairing so two people can listen to the same track.
Controls are on the band itself, including a mic for hands-free calls and volume and track buttons, plus a two-second press of the power button to bring up Siri or Google Assistant. In my opinion, this is the pick for someone who wants one pair of headphones for the gym, the commute and phone calls, and who values not thinking about charging. Who should skip it? Anyone who wants isolation from background noise, since there's no noise cancellation here, and anyone who refuses to depend on a battery.
The KZ EDX Pro goes the other direction entirely. It's a wired in-ear monitor with a 3.5 mm plug and a 0.75 mm gold-plated 2-pin (QDC) connector, which means the cable is replaceable — and replaceable with an upgraded cable if you want to experiment. The stock cable is a 5N OFC anaerobic copper flat cable, chosen for durability and to reduce tangling. There's no battery, no pairing, no charging: plug it in and it plays.
The audio design is where it earns its place. It uses a 10 mm composite magnetic dynamic driver with a frequency range of 10 Hz to 20 kHz, 24 ohm impedance and 112 dB sensitivity — the low impedance and high sensitivity mean a phone can drive it without much trouble, though the product notes that adding a DAC opens up more. Tuning is oriented toward popular music and ACG, with an emphasis on low-frequency density that suits electronic music and heavy instrumental tracks, while the transient response is quick enough for vocals and classical detail. The shells are skin-friendly resin, high-temperature molded with a UV varnish finish, and they're available in Classic Black, Cyan and White. The ear-hook shape is designed to stay put on stage or during a long gaming session.
That said, be clear about what you're buying. The current packaging includes one pair of ear tips, not a selection. The inline microphone is described as generally compatible with Android phones and MP3 players, so iPhone users should check before assuming call quality. And the "wireless technology: Bluetooth" field in the listing is misleading — the connectivity is wired 3.5 mm, so treat it as a wired IEM. In my opinion, this is for someone who listens critically at a desk, plays games, or performs, and who would rather spend on sound than on batteries.
Side-by-Side: Which Should You Choose?
• Best for battery life and freedom from charging anxiety → WAVEFUN Neckband (up to 12 hours, with a 45-minute full charge).
• Best for a quick top-up before you leave → WAVEFUN Neckband (15 minutes of charging yields about 4 hours of playback).
• Best for gaming and video with low audio lag → WAVEFUN Neckband (dedicated gaming mode at roughly 45 ms latency).
• Best for sharing music with someone next to you → WAVEFUN Neckband (group mode pairs two earbuds into one listening session).
• Best for pure sound quality on a budget-minded setup → keephifi KZ EDX Pro (10 mm composite magnetic dynamic driver, 10 Hz–20 kHz range).
• Best for bass-heavy electronic and instrumental music → keephifi KZ EDX Pro (tuning deliberately emphasizes low-frequency density).
• Best for tinkerers who want to upgrade later → keephifi KZ EDX Pro (replaceable 0.75 mm 2-pin cable and a 5N OFC stock cable).
• Best for hands-free calls while moving → WAVEFUN Neckband (built-in mic, band-mounted controls, Bluetooth 5.3).
If I had to pick one, I'd take the WAVEFUN Neckband. The reason isn't sound — it's that the neckband format solves the problems most people actually have: it charges fast enough that forgetting to plug it in isn't a crisis, it survives sweat, and it works for calls, games and video without a cable snagging on everything. The KZ EDX Pro is the better listen if you're sitting still with a good source, and the replaceable cable makes it the more future-proof of the two. But for a single pair to live with daily, I'd go wireless. Check the current price on Amazon before you decide, since that's the one variable that could flip this for you.
The WAVEFUN Neckband, clearly. It carries an IPX5 sweat and splash rating, the magnetic earpieces keep the buds together when they're out of your ears, and there's no cable to catch on your arms. The KZ EDX Pro is wired with an ear-hook fit, which stays put, but a cable while running is a nuisance.
No. Despite a confusing field in the listing, the KZ EDX Pro is a wired in-ear monitor with a 3.5 mm plug and a 2-pin connector. The WAVEFUN Neckband is the wireless option here, running Bluetooth 5.3 with a 10-meter range.
Both emphasize low frequencies, but differently. The KZ EDX Pro is tuned for dense, heavy low-frequency output with a 10 Hz dive, aimed at electronic and instrumental music. The WAVEFUN Neckband uses SBC and AAC codecs with a bass-forward tuning over a 10 mm dynamic driver. For critical listening, the KZ is the more revealing of the two; for casual listening on the move, the WAVEFUN is plenty.
The current packaging includes one pair of ear tips, and the listing notes the older multi-tip packaging is essentially gone. If you like experimenting with fit and seal, plan on buying tips separately. The WAVEFUN Neckband ships with a cable, eartips, a protective bag and a manual.
