• MiFE Fresh Music biggest strength: bone conduction drivers paired with IP68 waterproofing and a built-in MP3 player, so you can leave your phone in the locker and still have music — even underwater.
• MiFE Fresh Music biggest trade-off: a single-piece headband design with push-button controls, no charging case, and Bluetooth that specifically does not work while swimming.
• TANFESO biggest strength: a 40-hour battery figure, a digital display charging case and touch controls, all in a clip-on format that stays put for runners and glasses wearers.
• TANFESO biggest trade-off: IPX7 rather than IP68, no built-in storage, and a shorter two-month warranty.
• Pick MiFE Fresh Music if you swim, sweat heavily, or want phone-free playback. Pick TANFESO if you run long distances and want the battery to outlast your week.
This is the pair I'd hand to someone whose workouts include water. The IP68 rating is the headline spec — it's rated submersible, so rain, sweat, pool laps and a rinse under the tap are all inside its comfort zone. That's a meaningfully tougher claim than most sport headphones make, and it's the reason this model exists in the shape it does.
The second thing that stands out is the built-in MP3 storage. The listing text mentions both 4GB and 32GB in different bullets, which is a discrepancy worth knowing about, but the concept is the same either way: you load songs onto the headphones and play them without any phone nearby. For swimming that isn't a nice-to-have, it's the whole point, because Bluetooth doesn't travel through water. The product notes are explicit that you must switch to MP3 mode when swimming and that Bluetooth won't work in the pool. Read that as a design requirement, not a flaw.
Around 15 hours of playtime covers a lot of training sessions, and the bone conduction driver sends sound through your cheekbones so your ear canals stay open — you hear traffic, other runners and gym announcements. Controls are push-button, which is less slick than touch but arguably easier to operate with wet or gloved fingers. If you want a phone-free swimming and running companion, this is the one. If you mostly lift in a gym or want a pocketable case, skip it — it's a plastic, rubber and silicone headband in orange, and it lives on your head, not in your pocket.
The TANFESO M100 is built around battery and convenience. The 40-hour playtime figure is roughly two and a half times the MiFE number, and because these are clip-on earbuds that live in a charging case, topping them up is a habit rather than a chore. The case has a digital display, so you can see where you stand at a glance instead of guessing.
Bluetooth 5.4 is the newer spec here, rated for a stable connection up to 33 feet, with auto on-and-connect when you pull the buds from the case. Touch controls handle music and calls, and the microphone system is described as tuned to pick up your voice while reducing background noise. The ear hooks are soft silicone and the buds weigh 0.18 oz each, which matters more than it sounds: the design wraps around your ear rather than plugging the canal, so it stays put while running, dancing, or wearing glasses. The listing mentions an ergonomic surround and streamlined sinking design for exactly that reason.
Open-ear audio is also a safety feature here — you hear approaching cars while you run or cycle. The trade-offs are real, though: IPX7 means it handles sweat and rain but isn't pitched as swim-ready the way IP68 is, there's no built-in music storage, and the warranty runs two months. If your runs are long, your charging discipline is poor, and you want a case that tells you what's left, this is the better fit.
• Best for swimming → MiFE Fresh Music Bone Conduction Headphones. IP68 submersible rating plus MP3 mode is the only combination here that works in water.
• Best for battery life → TANFESO Open Ear Bone. 40 hours versus 15 hours is a wide gap, and the charging case makes refills painless.
• Best for phone-free workouts → MiFE Fresh Music Bone Conduction Headphones. Built-in MP3 storage means no device required at all.
• Best for long-distance runners → TANFESO Open Ear Bone. Lightweight clip-on buds, silicone hooks, 33-foot Bluetooth range and auto-connect suit mile after mile.
• Best for glasses wearers → TANFESO Open Ear Bone. The clip-on hook design is specifically described as staying on while wearing glasses; a headband is more likely to interfere with temples.
• Best for control feel → depends on you. MiFE uses push buttons that are easy to find by touch; TANFESO uses touch controls plus a display case. Neither has active noise cancellation.
• Best for the toughest outdoor conditions → MiFE Fresh Music Bone Conduction Headphones. IP68 beats IPX7 when the weather turns ugly.
• Best for pocketability → TANFESO Open Ear Bone. A charging case fits in a pocket or belt pouch; a headband does not.
If I were buying for myself, I'd take the MiFE Fresh Music Bone Conduction Headphones. In my opinion, water resistance and built-in storage are the two features that actually change what you can do with sport headphones, and IP68 plus MP3 mode covers swimming, heavy sweat and phone-free outdoor sessions in one move. The 15-hour battery is plenty for a training week and the push-button controls are practical. The TANFESO is the smarter pick if battery life and a display case are your priorities and your workouts stay dry — but for the broadest range of conditions, I'd go MiFE.
what are the best bluetooth headphones for running
There's no single answer, but the specs point clearly in two directions. The TANFESO Open Ear Bone suits runners who want 40 hours of playtime, a charging case with a digital display, lightweight 0.18 oz clip-on buds and Bluetooth 5.4 with a 33-foot range. The MiFE Fresh Music suits runners who want IP68 waterproofing and built-in MP3 storage so they can run without a phone.

Do bone conduction headphones work for swimming?
The MiFE Fresh Music Bone Conduction Headphones are rated IP68 and the product notes state you should use MP3 mode while swimming, because Bluetooth signals don't transmit through water. The TANFESO Open Ear Bone is rated IPX7, which covers sweat and rain but isn't presented as swim-ready. So if swimming is on your list, the MiFE is the one to look at.
Pricing changes constantly, so check the current price on Amazon using the button on this page rather than trusting any figure you see elsewhere. On specs alone, the MiFE earns its place with IP68 and built-in MP3 storage, while the TANFESO counters with 40 hours of battery and a display charging case — a straightforward trade of durability and storage against endurance and convenience.
