IPX4 vs IP55, IPX5, IPX7, IP67, IP44, IP24, IP78 | Ratings Comparison
By Robert Jones · 2021-09-14
You see those IP numbers on speakers and headphones – IPX4, IP55, IP67? For years, I just glossed over them. After a few soggy tests, I realised understanding them is key to protecting your gear. Let's break it down properly.
Right then, let's have a proper chinwag about these "IP" numbers you see plastered all over your outdoor speakers, headphones, and even some fancy AV kit these days. IPX4, IP55, IP67… for a good few years, I’ll admit, I mostly just skimmed past them. Figured "bigger number, better protection." Simple, eh? Not quite. After a couple of rather soggy outdoor testing sessions – one particularly memorable incident involved a rogue garden hose, a supposedly "splash-proof" speaker, and a very confused spaniel – I realised I needed to get my head around it properly. And so do you, especially if you’re dropping a fair few quid on something that’s meant to survive more than just a gentle breeze. It's not just about keeping the rain out, mind. These ratings actually give you a pretty precise idea of what sort of punishment your gear can take from both dust and water. Essential knowledge, I reckon. Especially when you’re thinking about taking that new portable speaker to the beach, out on the boat, or even just setting up a sound system for a garden party. Trust me, a little bit of homework here can save you a whole lot of grief and a potentially knackered speaker. And believe me, I've seen plenty of those come through the workshop over the years, all because someone misunderstood what "water-resistant" actually meant. ### **Quick Verdict:** **Don't just look for "waterproof"; truly understand the IP rating for real peace of mind and gear longevity.** ### **Who It's For:** * Anyone buying outdoor speakers, portable Bluetooth speakers, or headphones for active use, like camping or gym sessions. * Folks who want to genuinely protect their investment from accidental spills, clumsy kids, or the unpredictable British weather. * Those who frequently use electronics in damp, dusty, or rugged conditions – think building sites or even just a busy kitchen. * Anyone who’s ever had a "water-resistant" gadget die on them after a light shower or a splash by the pool. You know who you are. ### **Who Should Skip It:** * If all your gear lives safely indoors, never leaves the shelf, and never sees so much as a drop of tea, you might not need to pore over every detail. Though a basic understanding is never a bad thing. * If you’re only interested in the absolute cheapest gear, knowing the IP rating might just make you spend a bit more (wisely, I'd argue). Sometimes saving a tenner now costs you a hundred quid later.  *IPX4 vs IP55, IPX5, IPX7, IP67, IP44, IP24, IP78 | Ratings Comparison — tested in the SpeakersMag workshop.* ## Breaking Down the IP Code: Not As Mysterious As It Looks Every single IP rating follows a pretty straightforward format: `IP` followed by two digits. Sometimes, you’ll see an `X` in there. That `X` isn’t some secret code for extra protection, don't fall for that. It just means it hasn't been tested (or the manufacturer hasn’t bothered to declare a rating) for that particular type of ingress. Usually, it’s the solid particle protection that gets an `X` when they’ve focused solely on water resistance, which is common for some outdoor audio bits. You'll often see IPX4 or IPX7 on headphones, for instance. Doesn't mean it's terrible for dust, just means they didn't officially test for it. So, if you're taking your shiny new Bluetooth speaker to a sandy beach, an IPX-rated unit might still get sand in the works, even if it can survive a dip. * **IP**: Stands for Ingress Protection. A bit posh, perhaps, but it simply means how well it stops foreign objects from getting inside and messing things up. That could be anything from a stray finger to a dust storm. Proper important. ## First Digit: Solids – Keeping the Crud Out This first number tells you how well your gear stands up to solid objects. Think dust, dirt, fingers, tools – anything that shouldn't be rattling around inside your expensive electronics. A higher number here means better protection. * **0**: No protection at all. Don't even think about it. Leave it on the shelf in a sterile environment. * **1**: Protected against solid objects over 50mm. Basically, stops a hand or a large rock getting in. Not much else. Not for outdoor use, by any stretch. * **2**: Protected against solid objects over 12.5mm. Finger-proof, mostly. Decent for indoor use where you might poke it accidentally, but not sealed against much else. * **3**: Protected against solid objects over 2.5mm. Tools, thick wires, that sort of thing. Getting a bit better, but still no good for fine dust. * **4**: Protected against solid objects over 1mm. Most wires, small screws. Starting to offer some decent general protection, but dust is still a menace. * **5**: Dust protected. Not completely sealed, mind you, but enough to prevent harmful ingress. You might get a bit of dust inside, but not enough to ruin the electronics. Good for a dusty workshop or a building site, often seen on rugged speakers. * **6**: Dust tight. This is the gold standard. Absolutely no dust can get in. If you see this, your gear is sealed up proper against even the finest particles. Ideal for harsh environments where fine sand or flour might be an issue. Think desert holidays or bakery kitchens, if you happen to be taking your portable speaker to one! If you see an `X` in this position, like IPX7, it means no official rating has been given for solid particle protection. It doesn't mean zero protection, necessarily, just that it hasn't been tested to the standard. I've seen plenty of IPX7 speakers that are pretty well sealed, but I still wouldn't trust them in a sandstorm without a second thought. Always best to err on the side of caution. ## Second Digit: Liquids – Keeping the Wet Stuff Out This is where things get interesting for us speaker fans. The second digit deals with water, and again, a higher number means better protection. This is crucial for anything that might see a bit of rain, a splash by the pool, or even a full dunking. * **0**: No protection. At all. Not even a single drop. Keep it dry. * **1**: Protected against vertically falling drops of water. Think condensation, or very light rain if it's perfectly upright. Not exactly inspiring confidence, is it? Wouldn't trust this further than I could throw it, and I'm not throwing my speakers. * **2**: Protected against vertically falling drops of water when tilted up to 15 degrees. Slightly better, but still pretty useless for real-world scenarios. A slight drizzle, maybe. * **3**: Protected against spraying water. Water falling as a spray up to 60 degrees from vertical. So, a sprinkler, a gentle shower. Still not what I'd call "outdoor ready" for a proper British downpour. * **4 (IPX4)**: Protected against splashing water from any direction. This is where most "splash-proof" portable speakers land. It's fine for light rain, a bit of spray from a hose (if you're careful!), or a splash from the pool. It means you don't have to panic if someone knocks over a drink nearby. My old IPX4 speaker handled that rogue garden hose incident eventually, but it was a bit touch-and-go! * **5 (IPX5)**: Protected against low-pressure jets of water from any direction. Think a strong jet from a tap, or a slightly more aggressive hose. You can hose down your speaker gently with this rating. Good for outdoor parties where things might get a bit lively, or cleaning off mud from a camping trip. A definite step up from IPX4. * **6**: Protected against high-pressure jets of water from any direction. This is serious water resistance. You can blast it with a powerful jet. Great for marine speakers or industrial use. If your speaker has this, it's laughing at the rain. * **7 (IPX7)**: Protected against immersion in water, up to 1 metre for up to 30 minutes. Now we're talking "waterproof" in the truest sense for most people. Drop it in the bath, it'll be fine. Fall off the paddleboard with your speaker? It should survive. Just don't go deep sea diving with it. Crucial point: it's about *depth* and *time*. * **8 (IPX8)**: Protected against continuous immersion in water under conditions specified by the manufacturer. This means it can go deeper or for longer than IPX7, but you *must* check the manufacturer's specifics. It could be 3 metres for an hour, or 10 metres for 30 minutes. Always read the small print. This is often seen on serious marine equipment. ### What About the Combination Ratings? This is where it gets a bit fiddly, but important. An IP rating often combines these two digits. So, `IP55` means: First digit 5 (dust protected) and second digit 5 (protected against low-pressure jets of water). Simple, right? Let's look at some common ones and what they really mean for your audio gear. * **IP44**: Protected against solid objects over 1mm (4) and splashing water (4). Often found on outdoor lighting or speakers that are meant to be under an overhang. Not for direct rain exposure, really, but will handle general splashes. Decent for a sheltered patio area. * **IP55**: Dust protected (5) and protected against low-pressure jets of water (5). This is a really common and useful rating for many portable Bluetooth speakers and some outdoor patio speakers. It'll handle a good downpour and a dusty environment. A solid all-rounder for general outdoor use. You can wipe it down with a damp cloth, no bother. * **IP67**: Dust tight (6) and protected against immersion up to 1 metre for 30 minutes (7). Now this is a proper rugged rating! Absolutely no dust, and you can dunk it in the pool. Fantastic for serious outdoor adventurers, beach trips, or if you're just really clumsy around water. Many premium portable speakers aim for this or better. I've got a JBL Charge 5 in the workshop with this rating, and I've literally dropped it in the paddling pool numerous times for testing. Still going strong. * **IPX4**: As mentioned, no solid protection rating, but protected against splashing water from any direction. Common for earbuds and some cheaper portable speakers. Good for gym sweat or light rain, but not for hosing down or dunking. This is probably the bare minimum I'd look for if I was using something near any liquid. * **IPX5**: No solid protection rating, but protected against low-pressure jets of water. Better than IPX4 for water, so can take a bit more of a hosing. Still, be wary of dust and sand. Good for outdoor showers or near a sink. * **IPX7**: No solid protection rating, but protected against immersion up to 1 metre for 30 minutes. Excellent for accidental drops in water, but remember that 'X'. Sand at the beach could still be an issue. Many waterproof headphones carry this rating. * **IP24**: Protected against solid objects over 12.5mm (2) and spraying water (4). This is a bit of an odd one for audio, usually seen on things like bathroom lights. It means you can't stick your finger in easily, and it'll cope with a bit of condensation or spray. But definitely not designed for direct water contact or outdoor use. * **IP78**: Now this is a really uncommon one, and honestly, if you see an IP rating with a first digit of 7, it means it's been tested for *pressurised water submersion* – effectively, the ingress protection for solids is also achieved by the sealing for water. So an IP78 rating would mean it's protected against pressurised jets (like a 7 for solids implicitly, though not usually shown) and continuous immersion (8). You'll hardly ever see this on consumer audio gear, unless it's military-grade. If you do, it's practically invincible to dust and water within its specified immersion limits. You'd likely be paying a pretty penny for something this rugged. ## Practical Use Cases and What to Look For Alright, so you've got the numbers down. Now, how does this translate to buying your next bit of kit? It's about matching the rating to your intended use, simple as that. ### Portable Bluetooth Speakers * **Garden use, casual patio party:** IPX4, IP55. An IP44 might do if it's truly sheltered, but I'd lean towards IP55 for peace of mind. Rain happens, doesn't it? * **Beach, poolside, camping:** IP67. This is the sweet spot. Dust-tight for sand, and fully submersible in case it gets knocked into the pool or the sea (briefly!). Don't skimp here, or you'll regret it. * **Boating, serious watersports:** IP67 or IPX8 (with manufacturer specifics checked). If it's going to be exposed to constant spray or potential long-term immersion, aim for the higher end. Fusion Marine speakers, for example, often go above and beyond. ### Headphones and Earbuds * **Gym, running, sweating:** IPX4, IPX5. Sweat is corrosive, so anything below this won't last. I've seen plenty of cheaper earbuds die an early death from sweat ingress. IPX4 is a minimum for me if you're active. * **Outdoor cycling, hiking in light rain:** IPX4, IPX5. Again, good for splashes and light rain. If you're prone to dropping them in puddles, then an IPX7 is better. * **Swimming, showering:** IPX7, IPX8 (again, check specifics). This is where you need genuine water immersion protection. Shokz OpenSwim, for example, boasts IP68 for proper swimming. ### Outdoor Speakers (Permanent Installation) * **Under a sheltered eaves/patio:** IP44, IPX4. They'll be protected from direct rain mostly, but need to handle splashes. * **Exposed to elements, general garden:** IP55, IP56. You want something that can take a proper soaking and won't get clogged with leaves or dust. Consider these minimums for year-round British weather. * **Marine/Coastal environments:** IP66, IP67. Salt spray and strong winds are no joke. You need robust, sealed enclosures here. Companies like Monitor Audio and Klipsch make some fantastic, tough outdoor speakers that often hit these higher ratings. ### Common IP Ratings Comparison Table | Rating | Solid Protection | Liquid Protection (Water) | Typical Use Case | SpeakersMag Notes | |:-------|:-----------------|:--------------------------|:-----------------|:------------------| | **IPX4** | Not rated (X) | Splashing from any direction | Gym earbuds, light rain | Good for sweat, light drizzle.

Totally sealed. | | **IP68** | Dust tight | Continuous immersion (mfg. specified) | Serious marine gear, swimming headphones | The ultimate. Check depth/time limits. | ## Misconceptions and Robert's Warnings I've seen a few folks get caught out by these ratings, so let me just clear a few things up. Based on years in the workshop and a few embarrassing moments of my own. ### "Waterproof" vs. "Water-Resistant" Right, big one this. Manufacturers love to throw "waterproof" around like confetti. But technically, unless it's IPX8 or IP68 with very specific, generous immersion specs, it's rarely truly waterproof in an absolute sense. Most consumer gear is "water-resistant." IPX7 means it'll survive a dunk for a *limited time and depth*. Don't treat it like a submarine. And certainly don't press buttons *while* it's underwater unless the manufacturer explicitly says you can. That's a fast track to water ingress, usually. ### Saltwater vs. Freshwater Another trap. IP ratings are almost always tested with *freshwater*. Saltwater is a whole different beast. It's corrosive, conductive, and can wreak havoc on seals and electronics much faster. If you drop your IP67 speaker in the sea, rinse it thoroughly with freshwater as soon as you can. Don't just let it dry out with salt residue on it. Better yet, avoid dunking it in saltwater if possible unless it's specifically rated for marine environments. ### Temperature Extremes IP ratings don't account for temperature. Extreme heat or cold can affect seals and plastics, making them less effective. Leaving an IP67 speaker baking in direct sunlight on a summer day then immediately dunking it in cold water might cause issues due to thermal expansion and contraction. Be sensible. ### Wear and Tear Over time, seals can degrade. Accidental drops or impacts can compromise the integrity of the enclosure. That IP67 speaker you bought three years ago might not be quite as dust-tight or submersible as it once was, especially if it's had a hard life. Treat your gear with a bit of respect if you want those IP ratings to hold true. ## FAQ: Your Burning IP Questions Answered ### Q: My speaker is IPX7. Can I take it swimming with me? A: Yes, generally. IPX7 means it can be immersed in up to 1 metre of freshwater for 30 minutes. So, it's fine for a dip in the pool or a quick fall into a lake. Just remember that it's usually for *freshwater* and for a *limited time*. Don't go diving with it, and always rinse it if it goes in saltwater. ### Q: What's the difference between IPX4 and IPX5? A: IPX4 is protected against splashing water from any direction, like light rain or a drink spill. IPX5 is protected against *low-pressure jets* of water, meaning it can handle a stronger spray, like from a tap or a garden hose. So, an IPX5 speaker can take a bit more of a hosing down than an IPX4 one. A significant step up for outdoor use, in my opinion. ### Q: Is IP67 better than IPX7? A: Yes, IP67 is generally better. The '6' means it's completely dust tight, offering superior protection against sand and fine particles, which the 'X' in IPX7 doesn't cover. Both handle immersion up to 1 metre for 30 minutes, but the dust protection makes the IP67 much more versatile and robust for environments like beaches or dusty campsites. ### Q: My product has two IP ratings, like "IP67 and IP68". What does that mean? A: Manufacturers might list two ratings if a product meets *both* standards, perhaps for different conditions or if it exceeds the IP67 standard but doesn't have specific continuous immersion conditions for IP68. More commonly, you'll see a single rating that represents the highest standard it meets. If you see both, assume it meets at least IP67, and for anything beyond that, check the manufacturer's notes for the IP68 specifics. It's a bit confusing, I'll grant you, but usually means it's very robust. ### Q: Why do some products have an 'X' in their rating, like IPX4? A: The 'X' simply means that the product hasn't been tested or rated for solid particle ingress protection. It doesn't mean zero protection; it just means the manufacturer hasn't put it through the formal tests for dust or solid objects. It's common for earbuds or items where the primary concern is water from sweat or splashes, and dust protection wasn't a priority for certification. ## Final Word So there you have it, a proper deep dive into the world of IP ratings. It might seem like a load of jargon, but honestly, understanding these numbers can save you a fair bit of bother and cash in the long run. Don't just blindly trust the marketing blurb that says "waterproof" or "rugged." Look for the actual IP code, and now you know exactly what each digit means. Choose your gear wisely, matching the rating to how you'll actually use it. A cheap IPX4 might be fine for the odd splash, but if you're planning a proper adventure, invest in something IP67 or better. Your wallet, and your eardrums, will thank you for it. Keep those speakers sounding sweet, and more importantly, keep 'em dry (or wet, if they're meant to be!). Cheers.
