For the past seven years, I have tracked consumer tech through constant shifts in hardware, platforms, and the way people actually use devices. Covering everything from budget gear to flagship hardware, I focus on what readers need to know, not on buzzwords or launch cycle hype. My expertise spans gaming laptops and chairs, high-performance PCs, gaming monitors, printers, smartwatches, earphones, headphones, Bluetooth speakers, tablets, and more, with a particular emphasis on how these products hold up in daily use. Reviews, explainers, buying guides, and news pieces all share the same goal: giving readers enough detail to make confident decisions without wading through fluff. Away from deadlines, I spend a lot of time gaming and watching films and anime, which naturally filters back into the work. Performance, comfort, display quality, and sound are judged the way players and viewers experience them, not just by lab numbers, which keeps my coverage grounded in real scenarios rather than just benchmarks.

Any gadget that you buy today, be it a smartphone, laptop or even a small gadget like earbuds, comes with random specifications and big numbers. But once you buy that gadget, you realise that the number often means nothing in your daily usage.

Two such specifications are ANC and ENC in earphones. Now, these sound very similar, but they are completely different things.

One is for your music listening experience, while the other is for clarity during voice calls. But no brand really clarifies this. They just slap these buzzwords on the product page, and you buy the product thinking it is the best gadget for you.

I explained them to you in simple words, but if you want to know more, here is a brief explanation.

ANC vs ENC

In reality, you have to look for both of these features in the earphones you want to buy. To ease the hassle of going through each and every pair of earbuds, I have curated a list of earbuds with ANC and ENC that you should consider for your next purchase.

The Oppo Enco Air5 is a feature-packed pair of TWS earbuds with excellent battery life, reliable multipoint connectivity and a compact, lightweight design. The ANC does a decent job with constant background noise, but struggles in louder environments. I found the sound quality good enough for everyday listening. Long listening sessions can get uncomfortable, which is another thing to keep in mind. The biggest positives are the battery life, connectivity and useful HeyMelody app. Read my full Oppo Enco Air5 review.

Why you should choose this product?

Choose it if ANC and audio quality are your priorities. The dual driver setup, LHDC support, spatial audio and strong noise isolation make it particularly suitable for music and travel.

The realme Buds T500 Pro packs an unusually long feature list for its segment, including 12.4mm drivers, 50dB ANC and 56 hours of claimed battery life. It also supports LHDC, spatial audio, AI based environmental noise cancellation and Bluetooth 6.1. The compact case and lightweight earbuds make them easy to carry, while 45ms latency targets mobile gaming.

Buyers frequently praise the bass, sound quality, comfortable fit and ANC. Some users report good value overall, although reviews also mention weaker outdoor calling and occasional concerns about battery life.

Choose it if you want a feature rich pair at a relatively affordable price. Its strong bass, ANC, long claimed battery life, LHDC and gaming mode cover most everyday requirements.

The Noise Master Buds 2 offer both 51dB adaptive ANC and six-microphone ENC, and after using them for over a week, I found the noise cancellation to be a significant improvement over the previous generation. The improved fit and rubber fins create a tighter seal, which also helps with passive noise isolation. The Bose tuned sound is crisp and detailed, while calls benefit from the improved microphone setup. I also liked the head gesture controls, solid battery life and premium finish. However, the larger case is less pocketable, the tight fit can get uncomfortable during long sessions, and bass heavy music does not sound as punchy. Read my full Noise Master Buds 2 review.

What are buyers saying?

Buyers mostly praise the rich sound, deep bass, comfortable fit and ANC. However, calling performance receives mixed feedback, with some users reporting weak microphones despite otherwise good audio performance.

Why you should choose this product?

Choose it if sound quality is more important than maximum battery life. Bose-tuned audio, adaptive ANC, LHDC and spatial audio make it geared towards music and entertainment.

The GOBOULT Tenet Pro focuses on delivering a long list of features at a budget price. It offers 13mm drivers, 32dB ANC and a claimed 75-hour total battery life, along with quad-microphone ENC and dual device pairing. Bluetooth 6.0 and 45ms low latency target users who also game on their phones. App support adds further controls, while the lightweight design and IPX5-style protection make the earbuds practical for commuting, workouts and everyday listening.

What are buyers saying?

Early feedback focuses on the attractive pricing, long battery claim, bass heavy sound and feature set. Reviews also suggest that ANC is useful but should not be compared directly with more expensive earbuds.

Why you should choose this product?

Choose it if battery life and value matter more than advanced ANC. The large driver, app support, dual pairing and gaming mode give you plenty of features for everyday use.

The realme Buds Air8 Pro offer decent ANC along with a six-microphone setup and AI noise reduction for calls. During my testing, I found the ANC good enough for daily commuting, office use and casual travel, although using the maximum setting can create noticeable pressure in the ears. Call quality, on the other hand, was better than expected, with voices remaining clear even in busy surroundings.

The biggest highlight is the powerful bass, which makes these earbuds particularly enjoyable for hip hop, EDM and other bass-heavy music, while vocals and instruments still remain clear. I also liked the comfortable fit, excellent battery life and genuinely useful AI translation features. Read my full review for my detailed experience with the realme Buds Air8 Pro.

FAQs
ANC and ENC serve different purposes. ANC reduces surrounding noise while listening, while ENC helps make your voice clearer during calls.
Many earbuds offer both ANC and ENC, but they are separate features. Check the specifications before buying.
Not directly. ANC mainly reduces noise for the listener, while ENC is designed to reduce background noise picked up during calls.
No. ENC is primarily designed for voice calls and does not directly improve music listening or reduce noise for the listener.
If you listen to music in noisy places and also take frequent calls, having both features can make the earbuds more versatile.
