In-depth explanation

What the 52dB marketing figure actually means

Oraimo states the hybrid ANC system can reduce noise by up to 52dB under its testing conditions. This is not a guarantee of identical reductions for every frequency, ear shape or location. Low-frequency steady noise often behaves differently from sharp voices; a good ear-tip seal and correctly selected mode matter.

ANC-on battery figures differ

Oraimo specifies up to 11.5 hours per charge and 45 hours with the case when ANC is off, versus up to 9 hours and 35 hours with ANC on. The charging case figure includes recharges, not one uninterrupted session. Volume, call time and app lighting influence realistic results.

When transparency is useful

Transparency mode can let environmental sound through during conversations, but it is not a licence to disregard traffic or safety. Remove or lower earbuds when crossing roads and pay attention to surroundings. The best mode is the one that fits what you are doing, not necessarily the strongest possible cancellation.

How this affects your buying decision

Fit and surroundings are part of the specification

Technical figures do not capture whether an accessory remains comfortable for two hours on a bus or during work. For in-ear models, fit changes the seal, bass and passive isolation. Open-ear designs deliberately preserve environmental awareness but may leak sound at higher volumes. Compare the wearing style, not merely the headline Bluetooth revision.

Buying from a genuine model page

The product links in this guide point to particular Infinite Tech catalogue entries. Match the model code with the box, confirm included cables and accessories, and check the current checkout amount. Pricing can change as supplier costs and promotions change, so the figures below are a dated snapshot.

Buyer checklist before ordering

Use the model number, not a vague family name. Confirm the device and companion app supported by your phone, read the package contents, check the fit or form factor and ask about warranty documentation. A specification such as IPX5, up to 45 hours or ANC may be stated under conditions different from daily use. Choose on the basis of your actual environment, rather than assuming every feature improves every situation.

A practical ANC comparison without laboratory equipment

If your main listening problem is steady vehicle rumble, try an appropriately fitted ANC mode and compare it with ANC disabled at a safe moderate volume. Listen to both music and announcements, because cancellation can affect frequencies differently. The quoted 52dB limit is a manufacturer rating, not a realistic promise to erase every loud sound. A poor ear-tip fit can significantly change perceived noise reduction, and some people prefer transparency when approaching their stop.

For longer journeys, the battery trade-off matters: the advertised total is 45 hours with ANC off versus 35 hours with ANC on, and actual results depend on volume and calls. Do not use cancellation to cover dangerously loud surroundings by raising music volume. Travellers who need to hear station announcements should pause playback or use awareness modes cautiously. Check that your exact OTW-631 listing includes the controls and app version described by Oraimo.
