Today, headphones are no longer just "something for music." We use them for calls, meetings, workouts, travel, gaming, and relaxation. That's why the choice is often confusing: in-ear or over-ear, Bluetooth or cable, ANC or not, what kind of microphone, what kind of battery?

If you're buying headphones for the first time or want to replace old ones, you quickly find yourself amidst technical terms and marketing promises.

This guide gives you a clear overview of what really matters in headphones. We won't talk about "marketing numbers," but about things that actually affect sound, comfort, and use.

In the end, you'll know:

• which headphones are suitable for calls
• which ones for travel or sports
• what ANC and Bluetooth codecs mean
• and what to look out for so you don't buy the wrong model

1) First: what will you use them for the most?

Before looking at brands or prices, answer the most important question: what will you use them for the most?

The most common scenarios are:

Calls and meetings

• a good microphone is important
• stable Bluetooth connection
• comfort for extended use

Travel

• ANC (Active Noise Cancelling)
• comfortable ear cushions or tips
• good battery life

Sport

• stability in the ear
• sweat resistance
• lightweight construction

Working on a computer

• comfort during extended use
• cable or stable Bluetooth
• good microphone

Best sound

• quality drivers
• good sealing
• support for better codecs

Once you know what you'll use them for, the choice becomes much easier.

2) Headphone types: advantages and disadvantages

In-ear headphones (earbuds)

These are the most popular headphones today because they are small, practical, and easy to carry.

Advantages

• very portable
• good sealing (more bass)
• often have ANC

Disadvantages

• not comfortable for everyone
• microphone is often weaker in cheaper models

---

On-ear headphones

These headphones rest on the ear, not around it.

Advantages

• lighter than over-ear
• often more breathable for extended use

Disadvantages

• pressure on the ear can be tiring
• poorer sound isolation

---

Over-ear headphones

These are larger headphones that enclose the entire ear.

Advantages

• very comfortable
• larger drivers
• better isolation
• ANC often works better

Disadvantages

• larger and less practical to carry

---

True Wireless headphones (TWS)

These are Bluetooth earbuds without a cable between them.

Advantages

• maximum freedom
• charging case
• very practical for everyday use

Disadvantages

• battery wears out over time
• microphone depends on the model

---

3) Bluetooth or cable?

Bluetooth headphones

Bluetooth is the most practical solution today.

However, sound quality depends on:

• codec (SBC, AAC, aptX, LDAC)
• connection stability
• headphone quality

If you have problems with connection drops, the reason could be:

• many Wi-Fi devices around
• old system
• power saving on the phone

Sometimes it helps to:

• update the system
• reset the Bluetooth connection
• disable power saving

---

Wired headphones

The cable still has its advantages.

It's an excellent choice for:

• gaming
• working on a computer
• situations without sound delay
• If your phone doesn't have a 3.5 mm jack, you'll need an adapter.

Check out the category of cables and adapters:

4) ANC (Active Noise Cancelling): when is it worth it?

ANC means active noise cancellation.

Headphones with microphones listen to ambient sounds and create an opposing signal that reduces noise.

It helps most with:

• airplane
• bus
• train
• office
• air conditioning units

It helps less with:

• sudden loud noises
• speech right next to you

Important: ANC is not the same as good isolation. With in-ear headphones, the seal alone can make a big difference.

---

5) Microphone for calls: what really counts

If you're primarily buying headphones for calls, consider these things:

• number of microphones
• noise reduction algorithms
• Bluetooth connection stability
• microphone position

Practical tip:

If a model has many comments like “the other person can barely hear me”, it's best to skip it.

---

6) Comfort and fit

This is one of the most common mistakes when buying.

Many people buy headphones that are comfortable for the first 10 minutes, but then start to bother them.

For in-ear headphones

• choose the right size ear tips
• no bass without a good seal
• too tight ear tips cause pain

For over-ear headphones

• weight is important
• soft ear cushions
• pressure on the head

---

7) Battery and charging

For TWS earbuds, look for:

• how many hours the earbuds last
• how many hours the charging case adds
• whether they have fast charging

If you're on the go a lot, it's practical to also have a power bank with you.

Check out the selection of power banks:

8) Bluetooth codecs (SBC, AAC, aptX, LDAC)

A codec determines how sound is transmitted via Bluetooth.

SBC
Basic codec. Always works, quality is solid.

AAC
Common with iPhone. Stable and often better than SBC.

aptX / aptX HD / aptX Adaptive
Common with Android phones. Designed for better quality or lower latency.

LDAC
Higher bitrate and potentially better sound, but more susceptible to interference.

Important: both the phone and the headphones must support the codec.

---

9) Drivers and sound quality

Many manufacturers emphasize driver size (e.g., 10 mm), but that's not all.

What's important is:

• good sealing
• balanced tuning
• sound clarity

Quick sound test

When you get your headphones:

1. listen to a podcast
2. listen to a song with bass
3. listen to a song with vocals

If everything is clear and balanced, the sound is good.

---

10) Latency (delay)

Latency means that the sound arrives slightly later than the image.

This can be a problem with:

• video content
• games
• video editing

Solutions:

• gaming mode
• low-latency Bluetooth
• cable

If your phone doesn't have a 3.5 mm jack, an adapter might help:

---

11) Water resistance (IPX)

For sports, the IP rating is very important.

IPX4
sweat and splashes

IPX5 / IPX6
stronger jets

IPX7
short-term immersion

Caution: warranty often does not cover liquid damage.

---

12) Controls and app

Small things can greatly improve the user experience.

Useful features:

• physical buttons or touch controls
• quick ANC activation
• app with EQ
• switching between devices

---

13) Charging on the go

If you're out in the field a lot, the battery can quickly run out.

Practical setup:

• TWS headphones
• short cable
• power bank

Power banks are very useful for travel and long days:

14) What to buy according to the scenario

Headphones for calls

Look for:

• good microphone
• stable Bluetooth
• comfort

---

Headphones for travel

Look for:

• ANC
• comfort
• battery life

---

Headphones for sports

Look for:

• stability
• IPX protection

---

Headphones for best sound

Look for:

• good sealing
• quality tuning
• support for AAC / aptX / LDAC

---

Most common mistakes when buying headphones

• buying headphones without the right fit
• expecting complete silence from ANC
• looking only at numbers
• forgetting about connectors or adapters

---

Quick summary

First, determine the purpose of use.

Choose the type of headphones (in-ear or over-ear).

With Bluetooth, pay attention to codecs, but don't overcomplicate it.

ANC is very useful for travel, and IPX protection for sports.

For peace of mind, always have a power bank handy.
