How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want familiar on-ear sound with marathon battery life and simple Bluetooth switching, choose JBL Tune 510BT; if you need open-ear, fully waterproof headphones with built-in MP3 storage for swimming and sweaty workouts, choose ZOVIMAX Bone Conduction Headphones.
• JBL Tune 510BT — biggest strength: JBL Pure Bass tuning, up to 40 hours of playtime, and a fast 5-minute top-up that adds 2 hours of listening.
• JBL Tune 510BT — biggest trade-off: It's an on-ear design with no water protection rating, so sweat, rain and pool water are real risks.
• ZOVIMAX Bone Conduction Headphones — biggest strength: IPX8 waterproofing (submersion to 5 meters for up to 2.5 hours) plus 8GB of built-in MP3 memory for phone-free playback.
• ZOVIMAX Bone Conduction Headphones — biggest trade-off: No noise control and a shorter battery window — up to 8 hours of continuous playback away from a charger.
• Pick JBL Tune 510BT if you want the classic headphone experience for commutes, calls and long desk sessions.
• Pick ZOVIMAX Bone Conduction Headphones if you swim, run or train hard and want your ears open to traffic and surroundings.
The Tune 510BT is the straightforward choice. It's a wireless on-ear headphone built around JBL's Pure Bass sound signature — the same tuning family JBL puts in its loudspeakers — with a dynamic driver covering a 20 Hz to 20 kHz range, 32-ohm impedance and 103.5 dB sensitivity. Translated into everyday terms: it's easy to drive, so it plays loud and full from a phone without any extra gear. The padded headband and soft ear cushions are made for long wear, the earcups fold up for travel, and the whole thing weighs 5.6 ounces — light enough to forget you're wearing it on a two-hour train ride.
What really separates it is endurance and convenience. JBL rates the battery at up to 40 hours, and a 2-hour charge via the included Type-C cable fills it back up. If you're the kind of person who always forgets to charge, the 5-minute speed charge giving 2 extra hours is genuinely useful. Bluetooth 5 keeps the connection stable within about 10 meters, and you can pair two devices at once — so you can switch from a video on your tablet to a call on your phone without re-pairing. The mic and volume controls sit right on the ear cup, and a multi-function button summons Siri or Hey Google.
Buy it if you want one dependable headphone for commuting, work calls, podcasts and music, and you like the feel of something sitting on your ears. Skip it if you swim, if you sweat heavily during workouts, or if you need to hear traffic and your surroundings while you listen — this is a closed, on-ear design with no water rating and no noise control. One practical note from the manufacturer: if the fit feels tight at first, stretching it over something ball-shaped for a day or so and adjusting each earpiece usually loosens it up.
The ZOVIMAX X7 MAX is a different animal entirely. It's an open-ear bone conduction headphone, which means the sound reaches you through vibration rather than a speaker pressed against your ear canal — leaving your ears open to ambient sound. That's the whole point for runners and cyclists who don't want to be deaf to the world around them. Soft silicone pads sit on the cheekbones, an adjustable strap handles different head sizes, and the open design keeps air moving so your ears don't get swampy during long sessions.
The headline feature is water. This model carries an IPX8 rating and is built to survive full submersion to 5 meters for up to 2.5 hours. That's swimming-pool territory, not just "splash resistant." Because Bluetooth can't travel through water, ZOVIMAX includes 8GB of internal memory — roughly 2,000 songs — and an MP3 mode you toggle with a double-click. You load tracks by plugging the magnetic charging cable into your computer and copying files straight onto the headphone. That's a genuinely clever bit of design: no phone, no baggie, no armband.
On land, Bluetooth 6.0 handles low-latency, stable audio, and the upgraded 14.2mm dynamic drivers push more bass and clarity than the small drivers typical of this style. The call system is tuned to keep your voice clear on the move. Battery life runs up to 8 hours of continuous playback with a 2-hour magnetic charge, and the package includes the headphones, the charging cable, an adjustable cord and a manual, backed by a 2-year warranty.
Buy it if you swim laps, run outdoors, or want music without blocking your ears. Skip it if you want deep isolation, noise cancelling or the longest possible battery — none of those are on the menu here.
• Best for battery life → JBL Tune 510BT. Up to 40 hours versus up to 8 hours on the ZOVIMAX.
• Best for swimming → ZOVIMAX. IPX8, 5-meter submersion, 2.5 hours underwater, MP3 mode with no phone required.
• Best for calls and voice assistants → JBL Tune 510BT. On-ear cup mic, volume buttons, and one-touch Siri or Hey Google.
• Best for situational awareness → ZOVIMAX. The open-ear design keeps traffic, training partners and surroundings audible.
• Best for storing music on the device → ZOVIMAX. 8GB internal memory holds roughly 2,000 songs.
• Best for long desk or commute sessions → JBL Tune 510BT. Lightweight build, padded headband, foldable for a bag.
• Best for heavy sweating → ZOVIMAX. Silicone pads and water protection are built for it; the JBL has no water rating.
• Best for a simpler, more familiar experience → JBL Tune 510BT. Pair, press play, done — no mode switching.
If I had to pick one, I'd take the JBL Tune 510BT for general listening — the 40-hour battery, dual-device Bluetooth and on-cup controls make it the more versatile everyday headphone, and the foldable, lightweight build travels well. But that's a verdict for commuters and desk workers, not athletes. If you swim or train outdoors, the ZOVIMAX is the one I'd recommend, because no amount of battery life helps a headphone that can't get wet. Decide which of those two people you are, then check the current price on Amazon before you commit.

Both of these are wireless. The JBL Tune 510BT uses Bluetooth 5 to stream audio from your phone, tablet or laptop within about 10 meters, with controls on the ear cup. The ZOVIMAX adds a second path: bone conduction drivers vibrate against your cheekbones, and in MP3 mode it plays files stored in its own 8GB memory, with no connection needed at all.

Pair over Bluetooth from your iPhone's settings — the JBL Tune 510BT supports Bluetooth 5 and can stay connected to two devices simultaneously, so you can jump between a call and a video. It also has a multi-function button that activates Siri. The ZOVIMAX pairs over Bluetooth 6.0 the same way for land use, but underwater you'd switch it to MP3 mode, since Bluetooth doesn't transmit through water.
how to headphones noise cancelling
Neither of these has noise cancelling — both list noise control as "None." The JBL's on-ear cushions physically block some outside sound because they sit over your ears, but that's passive, not active cancellation. The ZOVIMAX is the opposite by design: it's open-ear, so it deliberately lets outside sound in. If true active noise cancelling is a must-have, neither model fits.

Setup is simple on both. The JBL arrives with a Type-C charging cable and a quick start guide; charge fully in about 2 hours, pair via Bluetooth, and use the ear-cup buttons for volume and calls. The ZOVIMAX charges magnetically in about 2 hours, and to load songs you connect that cable to a computer and drag music onto the built-in USB memory, then double-click to toggle modes.
