Wireless Headphones Buying Guide: ANC, Battery Life, Multipoint and LDAC Explained
Wireless headphone spec sheets are full of numbers: ANC depth, playtime, Bluetooth versions, codecs. It's hard to know which of them actually change your day. If you commute through Lahore traffic, study in a noisy hostel or take calls from a home office, a few features matter far more than the rest.
This guide explains what active noise cancellation, battery life, multipoint and codecs really mean, and compares Edifier wireless headphones available in Pakistan using their published specifications, so you can pick the right pair for how you listen.
Quick answer: If you travel or work somewhere noisy, prioritise strong active noise cancellation and a long battery. If you switch between a phone and a laptop, make sure the headphones support multipoint. For the best wireless sound quality, look for Hi-Res Audio Wireless certification and LDAC support, and check that your phone supports the same codec.

What is active noise cancellation?
Active noise cancellation (ANC) uses microphones to measure outside noise and plays an opposite sound wave to cancel it. It works best on steady, low-frequency sounds such as aircraft engines, bus rumble, generators and air-conditioner hum. Sudden or high-pitched sounds, like voices, are reduced less.
Hybrid ANC uses microphones on both the outside and inside of the ear cups, which usually gives stronger and more even cancellation. Edifier quotes ANC depth in decibels: the WH700NB Pro reaches up to -43dB, while the W830NB and ES850NB reach up to -45dB. A bigger number means more noise reduction under test conditions, although real-world results depend on fit and the type of noise.
ANC vs passive noise isolation
Passive isolation is the noise blocked physically by the ear cushions and the seal around your ears. Every closed-back headphone has some. ANC adds electronic cancellation on top.
- Passive isolation is always on, uses no battery and blocks higher-pitched sounds well.
- ANC targets the low, constant noise that passive isolation struggles with, but it uses battery power.
For a quiet room, good passive isolation may be enough. For travel, offices and noisy homes, ANC makes a clear difference and lets you listen at a lower, safer volume.
How much battery life do you need?
For most people, 30 hours or more is plenty for a full week of commuting and study. Longer battery life mainly means charging less often. Remember that ANC uses power, so playtime is usually lower with ANC on.
Fast charging matters too. The WH700NB Pro gives 10 hours of use from a 15-minute charge, and the WH950NB V2 gives 7 hours from 10 minutes, which is useful during load-shedding or when you forget to charge overnight.
What is multipoint connection?
Multipoint lets headphones stay connected to two Bluetooth devices at the same time and switch between them automatically. For example, you can watch a lecture on your laptop and still hear a call on your phone without re-pairing.
This is one of the most useful everyday features for students and anyone working from home. The W820NB Plus, W830NB, WH700NB Pro, W800BT Pro and ES850NB all support multipoint, and the W600BT can connect to two devices simultaneously.
Do codecs like LDAC matter?
A codec is how audio is compressed for Bluetooth. SBC is universal but basic; AAC works well with iPhones; LDAC can carry much more data for higher-quality wireless sound on supported Android phones.
The WH950NB V2 and ES850NB support LDAC and carry Hi-Res Audio Wireless certification. To benefit, your phone must support LDAC too, and you'll get the most from high-quality music files or streaming. If you mostly watch videos or listen casually, codec choice matters less than comfort and ANC.
What makes headphones good for calls?
Call quality depends on the microphones and the processing that removes background noise. Look for AI noise cancellation or environmental noise cancellation (ENC) on the mics. The W830NB, W820NB Plus, W800BT Pro and ES850NB use AI noise cancellation for calls, while the WH950NB V2 uses a 4-mic ENC system.

Best choice by use case
For long commutes and travel
The Edifier W830NB and ES850NB suit travellers because they combine up to -45dB ANC with very long published battery life. The ES850NB also folds and comes with a travel case.
For students on a budget
The Edifier W600BT is a simple wireless option without ANC. It offers up to 30 hours of playback, a built-in mic and a 3.5mm cable for wired listening, which is handy for exams, lectures and older laptops.
For work calls and home offices
Choose a model with multipoint and AI noise cancellation on the mics, such as the W820NB Plus or WH700NB Pro, so you can move between laptop meetings and phone calls without re-pairing.
For the best wireless sound
If your phone supports LDAC, the WH950NB V2 and ES850NB can take advantage of it, with Hi-Res Audio Wireless certification.

Frequently asked questions
Which Edifier headphones have the best noise cancellation?
Among the models listed here, the Edifier W830NB and ES850NB have the highest published ANC depth at up to -45dB. The WH700NB Pro follows at up to -43dB. Real-world results depend on fit and the type of noise, so a good seal around your ears matters as much as the number.
Is ANC worth it in Pakistan?
Yes, if you regularly deal with steady background noise such as traffic, generators, fans or long bus and flight journeys. ANC reduces that noise so you can listen at lower volume. If you mostly listen at home in a quiet room, a non-ANC pair like the W600BT may be enough.
Does ANC reduce battery life?
Yes. ANC uses power, so playtime is usually shorter with it switched on. For example, Edifier quotes the WH950NB V2 at 34 hours with ANC on and 55 hours with ANC off.
Can I use wireless headphones with a cable?
Many models support wired listening. The W600BT includes a 3.5mm cable, and the W800BT Pro supports Hi-Res audio over a USB-C wired connection. Check each product page for the cable options included.
Do Edifier headphones sold here come with warranty in Pakistan?
Yes. Products sold through the official Edifier distributor in Pakistan are genuine and backed by manufacturer warranty honoured locally, with after-sales support. Contact us for warranty details on a specific model.
Picking the right wireless headphones
Decide where you'll use them most. Noisy commutes and travel call for strong ANC and a big battery. Home offices benefit most from multipoint and good call microphones. If you want the best possible wireless sound, check that your phone supports LDAC before paying for it.
