If you only remember one thing: IPX4 shrugs off sweat and light splashes, IPX6 handles heavy rain and strong jets, and IPX7 survives being submerged in a metre of water for 30 minutes — while the IP67 on some outdoor speakers adds the dust-tight seal that IPX ratings never test. For earbuds, IPX4 to IPX5 is enough for nearly every workout; for a speaker that might sit poolside or take a dunk, go IPX7 or IP67.
This guide explains the differences between the three ratings people actually compare, then shows every BUGANi speaker and earbud with its officially published rating and price, so you can match the number to the place you really listen.
What IPX4, IPX6, IPX7 and IP67 Actually Mean
The IP code has two digits: the first rates protection against solid particles (dust), the second rates protection against water. When the first digit is an X, the manufacturer did not test or did not claim dust protection — the X says nothing about how dusty the device really is.
| Rating | What the test covers | Typical real-world use |
|---|---|---|
| IPX4 | Splashing water from any direction | Heavy sweat, light rain |
| IPX5 | Low-pressure water jets (6.3 mm nozzle) | Rain, rinsing under a tap |
| IPX6 | Powerful water jets (12.5 mm nozzle) | Downpours, strong spray |
| IPX7 | Immersion up to 1 m deep for 30 minutes | Falls into a pool, sink or tub |
| IP67 | Dust-tight plus immersion up to 1 m for 30 minutes | Beach, sand, rough outdoor use |
Two details change how you should read any of these labels. First, the tests use clean fresh water at fixed pressure for a fixed time — real rain, sweat and pool water are messier than the lab. Second, the water digits are not cumulative: IPX7 does not promise jet resistance, and IPX6 does not promise submersion resistance. That is why rugged devices sometimes carry combined ratings. The full standard is the International Protection Marking, defined by IEC 60529 and explained on Wikipedia.
IPX4 vs IPX6: The Difference Between Sweat and Rain
Choose IPX6 over IPX4 when your earbuds will face real rain instead of just perspiration: IPX4 stops splashes, while IPX6 also survives the powerful jets that a downpour or a hard bicycle commute throws at them.
Sweat is not a formal IP test at all — the rating you see on most gym earbuds is IPX4, and its splash test is simply the closest lab proxy for a soaked workout. That level is genuinely fine for the treadmill: BUGANi's only IPX4 model, the in-ear Freebuds B20 with active noise cancelling at $19.99, is built for exactly that job. Step up to outdoor running in open weather and the honest advice is IPX6: the open-ear Free B16 at $49.99 carries an IPX6 rating, so steady rain and splash from wet roads stay outside the case while the open fit keeps you aware of traffic. Neither rating means swimmable — no earbud rating below IPX8 is.
IPX6 vs IPX7: What Submersion Adds (and What It Does Not)
IPX7 is the rating to pay for when a device can end up fully underwater — which for most people means a speaker, not the earbuds already sitting in your ears.
The IPX7 test drops the product into fresh water up to 1 m deep for 30 minutes and expects it to keep working afterwards. Two BUGANi speakers carry it: the compact Brief Go at $59.99 (45 mm driver, up to 28 hours of playtime, Auracast multi-speaker broadcast) and the slimmer Brief at $59.99 (28 W peak, dual 45 mm drivers). Both are happy poolside, in the shower room or toppled off a cooler into the water. The catch: because IPX7 does not include a jet test, you should still avoid blasting either one with a pressure washer or a high-pressure hose — rinse gently instead.
IPX4 vs IPX7: The Real-World Gap (Earbuds vs Speakers)
Match the rating to where the device lives: an earbud spends its life in your ear and rarely needs more than IPX4-IPX5, while a speaker sits on wet tables, sandy towels and pool ledges — which is why the gap between an IPX4 earbud and an IPX7 speaker is exactly the gap between sweat and a dropped-in-the-water accident.
Buying decisions get easier once you see it that way. An IPX4 earbud is a reasonable daily driver and the Freebuds B20 proves you can get ANC at that level for $19.99. An IPX4 speaker, by contrast, would be a poolside liability, so every BUGANi speaker starts at IPX5 (splash and jet proof) and the outdoor models go to IPX7 or IP67. One more honest note: if you only want a speaker in the bathroom, steam is not immersion — IPX5 already covers that, and you do not need to spend extra on IPX7 for it.
IPX7 vs IP67: The Dust Digit Nobody Reads
IP67 means the same 1 m / 30-minute water test as IPX7, plus a dust-tight seal (first digit 6) — so if your speaker is heading to sand, gravel or a dusty backpack, IP67 is the meaningful upgrade and IPX7 is not.
Beach sand is the quiet killer of 'waterproof' speakers: it works its way into charging ports, grilles and button gaps, and no water rating does anything about it because the IP water tests use clean water with no particles. A dust-tight housing is the only real defence. In the BUGANi line-up that means the Rove Go 5 at $39.99 (50 mm driver, up to 24 hours of playtime, Auracast broadcast, carry strap) and the Brief TT at $69.99 (60 W output with RGB lighting) — both rated IP67 and both positioned for exactly this kind of outdoor life. Keep the port cover closed, rinse them with fresh water after salt exposure and dry them before charging.
The Full BUGANi Line-Up, Rated: Every Published Spec in One Table
Every rating and price below comes from the official BUGANi product listings; nothing here is estimated. Four models — the Free B15, Fit B18, AirCore OWH and Space BH01 — publish no IP rating at all, so treat them as not water-rated rather than assuming a level.
| Model | Published rating | Price | Best for |
|---|---|---|---|
| Freebuds B20 | IPX4 | $19.99 | Gym, office, everyday in-ear |
| Free B10 | IPX5 | $29.99 | Open-ear daily wear, calls |
| Free B11 | IPX5 | $25.99 | Long-battery open-ear workouts |
| Fit B17 | IPX5 | $29.99 | Clip-on open-ear, all-day wear |
| Clip B21 | IPX5 | $49.99 | Clip-on with lanyard, active use |
| Free B16 | IPX6 | $49.99 | Rainy runs, outdoor commuting |
| Reform | IPX5 | $99.99 | 120 W indoor-outdoor party sound |
| Brief Plus | IPX5 | $129.99 | 100 W broadcast parties |
| Brief Pro | IPX5 | $209 | Hi-Res 160 W, splash-safe events |
| Boost Max | IPX5 | $249 | 240 W flagship with power bank |
| Brief Go | IPX7 | $59.99 | Poolside, submersion risk |
| Brief | IPX7 | $59.99 | Compact poolside and travel |
| Brief TT | IP67 | $69.99 | Outdoor parties with RGB |
| Rove Go 5 | IP67 | $39.99 | Beach, sand, hiking, biking |
Two patterns stand out in the real line-up. Earbuds cluster at IPX4-IPX6 because they face sweat and rain, not submersion. Speakers cluster at IPX5 and above, with the two genuinely outdoor models (Rove Go 5 and Brief TT) taking the full IP67 route. If you have not read the deeper dives yet, our earlier comparisons of IPX4 vs IPX5 and IPX6 vs IPX7 cover the adjacent pairs in more detail.
Bottom Line: The Rating Cheat Sheet
- Gym, treadmill, light sweat — IPX4 is enough: Freebuds B20 ($19.99).
- Running in rain or cycling commutes — step up to IPX6: Free B16 ($49.99).
- Earbuds at the pool or beach — skip it; take a speaker instead.
- Poolside speaker that might get dunked — IPX7: Brief Go ($59.99).
- Sand, gravel and real outdoor abuse — IP67 only: Rove Go 5 ($39.99) or Brief TT ($69.99).
- Indoor or covered-venue parties — IPX5 is plenty and saves you nothing in sound: Brief Pro, Brief Plus, Reform or Boost Max.
No rating makes a speaker indestructible. The IP system tests clean fresh water and dust, not salt, sand or drops, so the practical routine is always the same: keep port covers closed, rinse with fresh water after the beach, dry before charging, and treat the rating as permission for the conditions it names — not a promise for everything else.
