Soundcore Q31i Noise Cancelling Headphone: Review, Pros & Cons

Summary

A budget wireless over-ear headphone with 40 mm drivers, Bluetooth 6.0, SBC/AAC/LDAC, four-microphone adaptive ANC and a passive 3.5 mm AUX input. Buy it for Android LDAC and long manufacturer-rated battery life; skip it if you need ANC, a working microphone or controls while plugged in by wire.

Strengths

SBC/AAC plus LDAC on compatible Android, with HearID and custom EQ, instead of a single fixed sound.
Manufacturer-rated endurance of up to 80 h with ANC off and 50 h with ANC on, which could make charging infrequent for commuting and travel.
Genuine left/right ear cushions snap out without tools and cost $14.99 a pair in the official accessories catalog.
Dual-device switching between phone and laptop, with the caveat that background notifications can interrupt switching.
Direct U.S. availability from the maker, Newegg (Anker Official Store seller) and Walmart listings that name the Q31i.
One October 2026 owner reported good Bluetooth sound, comfortable fit, adequate call microphone and favorable casual latency.

Weaknesses

AUX is passive: plugging in the 3.5 mm cable powers the electronics off, so ANC, the wired microphone, app EQ and all button controls stop working.
One October 2026 owner found AUX playback muddy and bass-heavy versus Bluetooth, with only slight improvement from a firmware update.
ANC can produce ear pressure, transient diaphragm pops after pressing a cup or on bumpy rides, and faint hiss with no music; voices and intermittent sounds persist.
ANC adapts to fit, so glasses or hair breaking the seal weakens it; the -37 dB figure is not a universal measured suppression.
No water or sweat rating, so rain, heavy sweat and spills can damage the electronics or pads.
LDAC disables multipoint, and the headphone boots into ANC at every power cycle unless the NC key is customized.

Verified specifications

Drivers	40 mm silk-and-metal/ceramic dual diaphragms; Hi-Res Audio wired and wireless certification per the maker.
Codecs	SBC, AAC and LDAC. LDAC must be enabled in the app, needs a compatible Android transmitter, and multipoint must be disabled while LDAC is active. iPhone does not provide LDAC.
ANC	four-microphone adaptive noise cancellation, five selectable levels, published roughly -37 dB maximum depth. That is a manufacturer specification with unspecified test conditions, not universal suppression at every frequency.
Call microphones	three-microphone AI-assisted voice processing for wireless calls.
Connectivity	Bluetooth 6.0 with dual-device multipoint and Google Fast Pair on supported Android; 3.5 mm AUX input works when switched off or on battery.
Power	up to 80 h normal/ANC off, 55 h transparency, 50 h ANC, 40 h ANC + LDAC; 50 h talk time; about 2 h full USB-C charge; 10-minute charge for up to 10 h of music at 50% volume with ANC off using a 5V/1A charger.
Weight and size	about 265 g (267 g in Japan); exterior roughly 161 x 86 x 183 mm (Japan).
Controls	five physical keys (power, volume up, volume down, NC, multifunction). App adds HearID 5.0, EQ, 3D/spatial sound without head tracking, five ANC settings, Nap Mode/white noise and AI/translation features.
ANC default	boots into ANC every power cycle; the NC key switches ANC and Transparency unless customized in the app.
Weather resistance	not water-resistant; no IP rating. Care instructions say stop using immediately if liquid gets in.
Warranty	18 months for qualifying manufacturer defects from an authorized U.S. purchase, with dated proof of purchase.
Returns	30-day direct-store return for undamaged qualifying purchases with original box and accessories; buyer pays return shipping for non-defect reasons.

Full research notes and sources

Battery life and charging

The headline numbers are manufacturer lab figures, not independently measured everyday times. Higher volume, LDAC, spatial processing and ANC can shorten them. The U.S. page advertises up to 80 h with ANC off, 50 h with ANC on, 55 h in transparency and 40 h with ANC plus LDAC, plus 50 h of talk time. A full USB-C charge takes about 2 h, and a 10-minute charge can deliver up to 10 h of music at 50% volume with ANC off from a 5V/1A charger. A separate official support index quotes 84 h normal, 58 h ANC and 57 h transparency from a 750 mAh battery; the cause of the discrepancy is not documented, so the 80/50 figures are the safer U.S. reference. In a September 2026 r/soundcore thread, one owner reported about 75% battery after roughly 18 h of light gym use, but phone and app percentages are not calibrated measurements.

ANC and sound

ANC helps steady low-frequency rumble such as engine or fan noise; voices and intermittent sounds persist. The support article acknowledges perceived pressure, stronger bass when ANC activates, brief diaphragm pops after pressing a cup or during bumpy vehicle movement, and faint processing hiss with no music. Suggested mitigations include lowering the ANC level in the app, adjusting cushion seal, avoiding compressing the cups and changing operating mode. Persistent squealing or abnormal noises need further troubleshooting. Manufacturer documentation also warns that background notifications or web video can interrupt multipoint switching, and that LDAC and two-device simultaneous use cannot run together.

Wired AUX mode

AUX is the main purchase caveat. Plugging in the 3.5 mm cable powers the headphone down automatically, so playback continues passively with no ANC, no onboard microphone for calls, no button controls and no app EQ. That removes Bluetooth latency but changes the whole feature set, which matters for low-latency gaming, mixing or corded office calls. One owner reported muddy, bass-heavy AUX playback versus the same headphone over Bluetooth and said a firmware update improved it only slightly. Because AUX is passive, source-side EQ is the only lever; a manufacturer firmware fix should not be assumed.

Repairs and running costs

There are no mandatory monthly fees or special battery consumables for standard Bluetooth, passive AUX, app EQ or ANC. Genuine Q31i ear cushions (left/right pair) cost $14.99 in the official accessories catalog, in black, white and pink; the DIY guide says to replace both ears together. A generic 30 cm USB-C cable is listed at $11.99 and a generic headphones case at $36.99, but neither is confirmed as a Q31i-specific required replacement. The internal 750 mAh battery is not advertised as user-replaceable, and no verified authorized cell part number, U.S. price or safe DIY guide was found. A planning scenario puts consumables at $0 a year if pads survive, $14.99 a year if one genuine pair is bought annually, or $7.50 a year averaged over two years; these are not measured pad-life figures. Charging energy per year was not quantified because pack voltage and wall energy per charge are not published.

Is it worth it?

At $69.99 with the promotional discount shown on the maker’s page, the Q31i is a good value for an Android buyer wanting LDAC, long rated battery life and replaceable pads. At $70 to $80 it remains reasonable for those features. At $89.99 list, compare the current Q30 at $67.99 discounted ($79.99 list), the Q20i at $39.97 and Space-series discounts before committing. The Q20i suits a price-conscious buyer who does not need LDAC or the newer adaptive settings; the Q30 suits a buyer who wants a known multi-year model at a lower promotional price; the Space Q45 at $129.99 ($126.99 on a selected sale) suits travel use if confirmed ANC refinement justifies roughly $40 to $60 more. These are buyer value thresholds, not transaction data.

Which model this is

This page covers the Anker soundcore Q31i, model family D1404, an over-ear wireless ANC headphone. Do not confuse it with the similarly named P31i true-wireless earbuds, the Q30/Q30i, Q20i, Space One or Space Q45. The maker’s U.S. page showed $89.99 for black in October 2026 with a $20 promotional discount also displayed; Newegg (Anker Official Store seller) listed $89.99 with free shipping and 30-day returns; Walmart listed $89.99 for a product explicitly named Q31i. The maker’s accessories catalog offers genuine ear cushions in black, white and pink. Ear cushion color availability does not imply the headphone itself ships in all three colors.
