If you want maximum battery life, over-ear active noise cancelling and multipoint pairing you can lean on all day, choose AUSDOM E7; if you need an open-ear, sweat-resistant headset built for running and long workouts, choose MZYDM Bone Conduction Headphones. These two sit at opposite ends of the same decision, and the specs make the split fairly obvious once you line them up.
• AUSDOM E7 — biggest strength: Up to 50 hours of playtime (35 with ANC on), dual 40mm dynamic drivers, and multipoint pairing that keeps you connected to two devices at once.
• AUSDOM E7 — biggest trade-off: It's a full over-ear design at 9.6 ounces, ANC doesn't work in wired mode, and it isn't built for sweat or rain.
• MZYDM Bone Conduction Headphones — biggest strength: Open-ear bone conduction at just 29g with IPX6 sweat resistance, Bluetooth 5.4 and its own multipoint connection.
• MZYDM — biggest trade-off: 15 hours of playtime is a fraction of the AUSDOM's, and open-ear bone conduction leaks sound and can't isolate you from a noisy train.
• Who each pick is for: AUSDOM E7 suits commuters, remote workers and long-haul travelers; MZYDM suits runners and gym-goers who want their ears open to traffic and their headset dry.
The AUSDOM E7 is a classic over-ear active noise cancelling headphone, and the spec sheet reads like one. It pairs over Bluetooth 5 with a 33-foot range, drives audio through dual 40mm dynamic drivers covering 20Hz–20,000Hz, and charges in about 2.5 hours. The headline number is battery: up to 50 hours in standard mode, or roughly 35 hours with ANC switched on. That's the kind of figure that means you can leave the charging cable at home on a week-long trip.
What makes it genuinely useful for a busy day is multipoint connectivity. The E7 holds a connection to two devices at once, so you can be listening to something on a laptop and still take an incoming call on your phone without repairing anything. That single feature is the reason I'd point most desk workers here. The touch controls handle volume, the earcups use protein leather over memory foam, and the 3.5mm jack means it still works as a wired headphone when the battery is flat — a nice fallback on a plane or a PC.
Two honest caveats. First, AUSDOM itself notes that the ANC is not total isolation — human speech still comes through, and ANC does less in already-quiet rooms. Second, ANC only functions in Bluetooth mode, so the wired mode is a plain listening mode. And at 9.6 ounces with a leather-and-steel build, this is a sit-down headphone, not something I'd wear for a run. If you're shopping for the best Bluetooth headphones for running, this isn't the one.
MZYDM Bone Conduction Headphones: Who It's For
MZYDM's model A28 is the other philosophy entirely. It's an open-ear bone conduction headphone that sits on the cheekbone rather than in or over the ear, weighs just 29g, and uses a flexible hook shape that MZYDM says can be bent freely. The frame is rubber with a plastic carry case included, and it ships in black only. Bone conduction drivers are rated at 50 ohm with 92dB sensitivity and a 20Hz–20,000Hz range, driven by 15mm speaker units.
The sports case is strong on paper. IPX6 means it shrugs off sweat and rain — MZYDM is explicit that it isn't for swimming, but for running, cycling and gym work it's the right rating. Fifteen hours of music and calls is plenty for a week of short runs, and Bluetooth 5.4 brings lower latency and a more stable connection than older versions. It also supports multipoint: MZYDM's own description gives the example of taking a call on your phone while music on your laptop pauses automatically. Controls are physical push buttons, which I actually prefer with sweaty hands — no touch panel to miss.
The trade-offs are the flip side of the design. Open-ear means nothing blocks outside noise, which is exactly why runners like it and exactly why it's poor on a plane. Fifteen hours won't get you through a long international trip the way the AUSDOM will. And bone conduction audio has less bass weight than a 40mm dynamic driver in a sealed cup. The 2.5mm jack on the spec sheet is unusual and worth checking your cable situation if you ever want wired use.
Buy it if you run, ride or train outdoors and want your ears open to traffic and your headset immune to sweat. Skip it if you mainly want to block out engine noise or you listen in long, uninterrupted stretches.
Side-by-Side: Which Should You Choose?
• Best for running and workouts → MZYDM. IPX6 sweat resistance, 29g, open-ear fit. This is the headset for running in this pair.
• Best for commuting and flights → AUSDOM E7. Active noise cancelling and sealed over-ear cups beat open-ear for engine drone.
• Best for awareness of your surroundings → MZYDM. Open-ear bone conduction leaves your ear canal clear, which matters on roads and trails.
• Best for multipoint pairing across laptop and phone → a tie. Both list multipoint, so the deciding factor is which form factor you'll actually wear.
• Best for wired fallback and PC/TV use → AUSDOM E7. 3.5mm jack, Bluetooth 5, and a 33-foot range.
• Best for long listening comfort in one sitting → AUSDOM E7. Protein leather and memory foam earcups are designed for marathon sessions — though 9.6 ounces is real weight.
• Best for a low-fuss, sweat-friendly fit → MZYDM. Button controls and a bendable frame are easier to live with mid-workout.
If you're weighing volume limiting sports earbuds for running against a full ANC headphone, note that neither sheet lists a volume limiter — so if hearing protection is your priority, that's a separate category, not these two.
In my opinion, most people shopping this comparison should buy the AUSDOM E7. Multipoint pairing, up to 50 hours of playtime, ANC and a 3.5mm wired fallback make it the more versatile headphone for commuting, work and travel — the everyday jobs most of us actually use headphones for. But if running is your main use, I'd buy the MZYDM Bone Conduction Headphones instead: IPX6, 29g and an open-ear fit are the right answers for a run, and no amount of ANC makes an over-ear headphone pleasant at mile three. Decide which of those two lives is yours, then check the current price on Amazon before you commit.
FAQ
How to pair multiple headphones
How to pair multiple headphones iphone
On iPhone, open Settings, then Bluetooth, and pair each headphone one at a time. iOS holds the pairing for each device, so you can move between them from the Bluetooth menu or the audio output selector. Neither the AUSDOM E7 nor the MZYDM changes that iPhone behaviour; multipoint on both simply lets one headphone stay linked to your iPhone and a second device like a laptop.
How to pair multiple headphones on ipad
The process on iPad mirrors the iPhone: Settings → Bluetooth → pair each headset in turn, then pick the active output from Control Center. If you want one headset connected to both an iPad and a phone simultaneously, that's multipoint, and both products here list it. Just remember only one audio stream plays at a time on each.
How to pair multiple bluetooth headphones
There's no universal trick — pairing is per headphone, per device. Put each headphone in pairing mode, add it in your device's Bluetooth settings, and repeat for the next one. Multipoint, which the AUSDOM E7 and MZYDM both support, is the feature that keeps a single headphone connected to two devices rather than forcing you to re-pair every time you switch.
