Wireless Earbuds Buying Guide 2025: ANC, Codecs & More Explained

Wireless earbuds have become essential daily gear—for commuting, working from home, exercising, or simply enjoying music without tangled cables. But the market is flooded with options ranging from €20 to €300+, each advertising different features with confusing acronyms.

ANC, LDAC, IPX5, multipoint—what do these actually mean, and which ones matter for your needs?

This guide cuts through the marketing jargon and explains what you genuinely need to know before buying wireless earbuds in 2025.

Active Noise Cancellation (ANC): Worth the Extra Cost?

ANC is the most marketed feature in earbuds today. Understanding how it works helps you decide if it’s worth paying extra for.

How ANC Works

Active Noise Cancellation uses microphones to pick up ambient sounds (traffic, airplane engines, office chatter), then generates an inverse sound wave that “cancels out” the noise. When these opposing waves meet, they neutralize each other through destructive interference.

The result: you hear less background noise without cranking up your music volume.

Types of ANC

Not all ANC is created equal:

Feedforward ANC: Microphones on the outside of the earbuds capture external noise. Simple but can be thrown off by wind or inconsistent fit.

Feedback ANC: Microphones inside the ear canal capture what you actually hear. More accurate, but can create feedback loops if poorly designed.

Hybrid ANC: Combines both—microphones inside and outside. This is the gold standard in 2025 and what you’ll find in quality earbuds. Look for “Hybrid ANC” if noise cancellation matters to you.

What ANC Can (and Can’t) Do

Works well against:

• Airplane and train engine noise
• Air conditioning and fan hum
• Traffic and road noise
• General office background noise

Struggles with:

• Sudden, irregular sounds (doors slamming, dogs barking)
• High-pitched voices (babies crying, alarms)
• Conversations directly next to you

Realistic expectations: Good ANC reduces noise by 20-40dB—cutting background noise to roughly one-quarter to one-sixteenth of its original level. It won’t create total silence.

ANC and Battery Life

ANC requires processing power, which means reduced battery life. Expect 20-30% less playtime with ANC enabled compared to having it off. If a manufacturer claims “8 hours with ANC,” you might get 10-11 hours without it.

Do You Need ANC?

Yes, if you:

• Commute on public transport regularly
• Work in open-plan offices
• Fly frequently
• Want to listen at lower volumes (better for hearing health)

Probably not, if you:

• Mostly use earbuds at home in quiet environments
• Need to hear your surroundings (cycling, running outdoors)
• Want maximum battery life
• Are on a tight budget

Audio Codecs: Why Your Phone Matters

A Bluetooth codec determines how audio is compressed and transmitted wirelessly. The codec affects sound quality, but here’s the catch: both your phone and earbuds must support the same codec to use it.

The Main Codecs Explained

SBC (Subband Coding)

• Universal fallback codec—everything supports it
• Basic quality, up to 328 kbps
• Higher latency (noticeable delay in videos/games)
• You’ll use this if nothing better is available

AAC (Advanced Audio Coding)

• Apple’s preferred codec—optimized for iPhones
• Up to 320 kbps, efficient compression
• Works on Android but performance varies by device
• If you have an iPhone, this is your best option

aptX (and variants)

• Qualcomm’s codec family, common on Android phones
• aptX: 352 kbps, low latency—good for videos and gaming
• aptX HD: 576 kbps, 24-bit audio—better quality, stable connection
• aptX Adaptive: 279-420 kbps, automatically adjusts to conditions
• Not supported on iPhones

LDAC (Sony)

• Highest quality: up to 990 kbps, 24-bit/96kHz audio
• Built into Android since version 8.0
• Can reduce battery life by up to 30%
• Connection can stutter in wireless-congested areas at highest settings
• Best for audiophile listening on Android

Quick Codec Recommendations

Do Codecs Really Matter?

For most people listening to Spotify or YouTube? Honestly, not much. The differences between AAC and SBC are noticeable but not dramatic.

Codecs matter most if you:

• Listen to high-resolution audio files (FLAC, hi-res streaming)
• Are genuinely picky about audio quality
• Use earbuds for video calls or gaming (latency matters)

Water Resistance: Understanding IP Ratings

If you exercise with earbuds or live somewhere rainy, water resistance matters. But “water resistant” means different things depending on the IP rating.

What IPX Numbers Mean

The “X” means dust protection wasn’t tested. The number indicates water protection level.

IPX4 (Splash-resistant)

• Protected against water splashes from any direction
• Safe for: light rain, sweat during workouts, accidental splashes
• NOT safe for: heavy rain, showering, submersion

IPX5 (Jet-resistant)

• Protected against low-pressure water jets
• Safe for: running in rain, sweaty workouts, washing under a tap briefly
• NOT safe for: swimming, showering, submersion

IPX7 (Submersion-resistant)

• Can be submerged in 1 meter of water for 30 minutes
• Safe for: accidental drops in water, heavy rain
• NOT safe for: swimming laps, saltwater

IPX8 (Deep submersion)

• Can be submerged deeper than 1 meter (manufacturer specifies depth)
• Closest to “waterproof” but still not truly waterproof

Important Caveats

1. IP ratings degrade over time. After months of sweat exposure and regular use, protection diminishes.
2. Saltwater and chlorine are worse than freshwater. Beach and pool use accelerates damage.
3. The charging case often has lower protection. Your earbuds might be IPX5, but the case might only be IPX2 or have no rating.
4. Warranty rarely covers water damage. Even with an IP rating, manufacturers often exclude “liquid damage” from warranty terms.

Minimum Recommendation

For gym and outdoor use: IPX4 minimum, IPX5 preferred. Anything less is risky with sweat and rain.

Multipoint Connection: Connect to Two Devices

Multipoint lets your earbuds connect to two devices simultaneously—like your laptop and phone. When a call comes in on your phone while you’re watching a video on your laptop, the earbuds automatically switch.

How It Works

Your earbuds maintain active connections to both devices but can only play audio from one at a time. The earbuds prioritize:

1. Incoming calls (highest priority)
2. Notifications and alarms
3. Media playback (lowest priority)

Switching happens automatically when audio from the higher-priority device begins.

Do You Need Multipoint?

Essential if you:

• Work from home and switch between laptop and phone
• Take calls on your phone while using earbuds with a computer
• Use multiple devices throughout the day

Unnecessary if you:

• Only use earbuds with one device
• Don’t mind manually switching connections
• Prioritize battery life over convenience (multipoint uses slightly more power)

Important Note

Not all earbuds support multipoint—it’s still a premium feature. Budget earbuds often lack it. Check specifications before purchasing if this matters to you.

Battery Life: Real-World Expectations

Manufacturers love to advertise impressive battery numbers, but the fine print matters.

Understanding the Numbers

Earbuds alone: Typically 4-8 hours per charge. This is what you get before needing the case.

With charging case: Adds 2-4 additional full charges. Total might be advertised as “30 hours” but that requires returning earbuds to the case multiple times.

What Affects Battery Life

Reduces battery life:

• ANC enabled (20-30% reduction)
• LDAC codec (up to 30% reduction)
• High volume levels
• Cold temperatures
• Multipoint connections (slight reduction)

Battery degrades over time. After 2-3 years of daily use, expect capacity to drop to 70-80% of original.

Realistic Expectations

If earbuds claim “8 hours with ANC,” expect:

• 6-7 hours in real-world mixed use
• 5-6 hours at high volume with ANC
• 9-10 hours with ANC off at moderate volume

Fit and Comfort: Often Overlooked

Sound quality means nothing if earbuds hurt after 30 minutes or fall out constantly.

Ear Tip Sizes

Most earbuds include S/M/L silicone tips. The right size:

• Creates a seal (important for bass and ANC effectiveness)
• Stays in place during movement
• Doesn’t cause pressure or pain

Tip: If one size feels “almost right” for both ears, try a different size on each ear. Ears aren’t always symmetrical.

Ear Tip Materials

Silicone (most common): Easy to clean, durable, decent seal. Works for most people.

Memory foam: Better seal and passive noise isolation. More comfortable for long wear but wears out faster and harder to clean.

Stem vs Stemless Design

Stem earbuds (like AirPods): Generally better microphone placement for calls, easier to remove.

Stemless/compact earbuds: More discreet, sometimes more comfortable for side sleeping, but call quality may suffer.

What to Look for by Use Case

Daily Commuting

Music Enthusiast

Priorities: Hi-res codec support (LDAC, aptX HD), good driver quality
Nice to have: Companion app with EQ customization
Can skip: IP rating (unless also exercising)

Budget-Conscious

Priorities: Good sound per euro, reliable Bluetooth, decent battery
Accept: Basic ANC or none, SBC/AAC only, fewer features
Avoid: Unknown brands with suspiciously low prices

Common Mistakes to Avoid

1. Buying Based on Brand Name Alone

Premium brands charge premium prices, but mid-range alternatives often match 80% of the quality at 50% of the price. Research specific models, not just brands.

2. Ignoring Companion App Features

Many earbuds unlock their full potential through companion apps—EQ customization, ANC adjustment, firmware updates, find-my-earbuds features. Check if an app exists and what it offers.

3. Assuming “Wireless Charging” Means Fast

Wireless charging cases are convenient but charge slower than USB-C. If you’re always in a rush, wired charging might be more practical.

4. Overlooking Microphone Quality

If you take calls, microphone quality matters as much as speaker quality. Reviews rarely focus on this—look for specific call quality mentions.

5. Buying for Features You Won’t Use

Don’t pay extra for LDAC if you stream Spotify on an iPhone. Don’t pay for IPX8 if your earbuds never leave your desk. Match features to your actual use.

FAQ

Are expensive earbuds worth it?

Diminishing returns kick in around €80-€120. Beyond that, you’re paying for refinement, not transformation. The jump from €30 to €80 earbuds is more noticeable than €150 to €300.

Do wireless earbuds work with all phones?

Yes, basic Bluetooth audio works universally. Specific codecs (LDAC, aptX) require phone support. ANC and other features work regardless of phone brand.

How long do wireless earbuds last?

With daily use, expect 2-4 years before battery degradation becomes annoying. Build quality varies—premium earbuds often outlast budget ones.

Can I use just one earbud?

Most modern earbuds support mono mode for calls or when you need to hear surroundings. Check specifications for “independent use” or “mono mode.”

Do I need Bluetooth 5.0 or higher?

Bluetooth 5.0+ offers better range and stability, but audio quality depends on codecs, not Bluetooth version. Most earbuds sold in 2025 are Bluetooth 5.0+ anyway.

Are there earbuds for small ears?

Yes—look for “compact” or “small fit” earbuds, or brands that include XS ear tips. Some models are specifically designed for smaller ear canals.
