Sony WF-C710N Review

Design and Comfort

The WF-C710N is a compact, lightweight pair of true wireless buds. Sony lists them at 5.2 g each, with a 38 g charging case. They are chunkier than the older WF-C700N, and What Hi-Fi? suggests people with smaller ears try the smaller of the three included tip sizes. They come in Black, White, Pastel Pink and a translucent Glass Blue.

Reviewer feedback on comfort is largely positive. Tom's Guide found them snug and comfortable across an 8-hour stretch, and SoundGuys agreed they are comfortable. The catch is security. There are no fins or wings, so SoundGuys and RTINGS both say they suit light workouts only, and some owners report the buds loosening in their ears. IPX4 protects against sweat and splashes, and wear detection and touch controls are included.

Build is where the price shows. Tom's Guide and What Hi-Fi? both describe the case as plasticky. One SoundGuys owner also said the ear tips wear out and are hard to replace, though that is a single account.

Sound Quality

The consistent verdict from independent sources is a warm, bass-forward sound with soft treble. RTINGS calls the signature warm, with bass emphasized by about 2 dB and treble under target by about 4 dB. SoundGuys' lab data shows a little extra bass below 100 Hz and slightly recessed mids around 500 Hz. It also shows a large treble dip near 10 kHz, roughly 14 dB under its target curve, which takes some sparkle from cymbals and upper harmonics.

In practice, that suits pop, hip-hop and electronic music. Tom's Guide called the bass fantastic, and What Hi-Fi? described it as full and controlled with good detail for the money. Scarbir found the out-of-box tuning a bit too bassy and smooth. SoundGuys still gave it a strong overall lab quality score of 4.8/5.

The Sound Connect app helps if the tuning isn't to your taste. It offers a 5-band custom EQ with presets, and the Bass Boost preset adds about 10 dB of sub-bass, so most people will want to leave that one alone. Codec support is basic: SBC and AAC only, with no aptX or LDAC. That is fine for iPhone users, but Android users who want higher-resolution streaming will have to look elsewhere.

Noise Cancellation

For a sub-$120 pair of earbuds, the ANC is a highlight, though opinions differ on how strong it is. SoundGuys scored it 8.5/10, measured up to about 30 dB of low-frequency reduction and reported an average external-noise reduction of about 85%. Tom's Guide called it highly effective and compared it with Bose at a lower price.

Other reviewers are more measured. RTINGS found isolation good but bass-range cancellation weak, and rated it slightly below the Sony LinkBuds S and the Soundcore Space A40. What Hi-Fi? placed it ahead of the WF-C700N but behind the WF-1000XM5 and Bose QuietComfort Earbuds, particularly on upper mids and highs. Scarbir noted an annoying rumble with ANC on. Expect a clear improvement on commuter noise, but not flagship-level silence.

Reports also conflict on controls. What Hi-Fi? describes ANC as on/off, while Tom's Guide says you can adjust the level in the app and describes 20 ambient levels. We could not resolve this, so check the app if adjustable ANC matters to you. Ambient Sound and Quick Attention modes are included.

Battery and Connectivity

Sony rates the buds at up to 8.5 hours per charge with ANC on, and about 30 hours in total with the case. With ANC off that rises to 12 hours per charge. Tom's Guide gives a 33.5-hour ANC-off total and What Hi-Fi? says 40 hours. Sony's own number for that wasn't found, so treat it as roughly 33 to 40 hours. Charging is USB-C only, with no wireless charging, and some owners complain of battery draining while the buds sit in the case.

Bluetooth 5.3 is supported, even though Amazon's spec field lists 5.0. Multipoint lets you stay connected to two devices at once, and owners praise it as smooth. SoundGuys had no connection problems with iPhone or Android, while RTINGS reported that connections are sometimes slow and unreliable. Calls get good marks. What Hi-Fi? found them very impressive for the class, and SoundGuys notes some vocal loss in street noise.

There is no low-latency mode. RTINGS says delay is too high for wireless gaming, and PC Gamer found it fine for casual play. Competitive players should look elsewhere.

Who Should Buy the WF-C710N

• Commuters on a budget who want real noise cancelling without spending flagship money.
• Bass lovers who enjoy a warm, smooth sound and don't mind soft treble.
• Anyone with two devices who wants easy multipoint switching between a phone and a laptop.
• Light exercisers who need sweat resistance but not a locked-in fit.

If you want stronger ANC and a more refined sound and can spend more, the Sony WF-1000XM6 is the step up. iPhone users may prefer the Apple AirPods Pro 3, and Samsung phone owners should look at the Samsung Galaxy Buds 4 Pro. If you don't need earbuds, the 1More SonoFlow offers very long battery life in an over-ear design.

Final Verdict

The Sony WF-C710N doesn't beat the flagships at anything, but it covers the basics well. It delivers a warm, enjoyable sound, ANC that handles low-frequency noise, light and comfortable buds, and multipoint support. The soft treble, limited codecs, so-so fit for workouts and plasticky case keep it from being a standout. At its common street price of around $80 it is a strong value, but at the $119.99 list price you should compare alternatives first.
