Sony has expanded its audio lineup with the WF-C710N truly wireless earbuds and introduced new color options for the WH-CH520 wireless headphones. Both models cater to different listening preferences—whether you prefer the compact convenience of earbuds or the over-ear comfort of headphones.

WF-C710N

2. Sound Quality & Noise Cancellation

WF-C710N

5mm Drivers: Delivers powerful bass and clear vocals.
DSEE (Digital Sound Enhancement Engine): Upscales compressed audio for richer sound.
Active Noise Cancellation (ANC): Uses Dual Noise Sensor tech (two mics per earbud) to block external noise effectively.
Ambient Sound Mode: Adjusts external noise levels (20 levels) for situational awareness.

WH-CH520

No ANC: Relies on passive noise isolation (not as effective as ANC).
Balanced Sound: Good for EDM, rock, and podcasts, but lacks bass depth compared to WF-C710N.
Custom EQ via Sony App: Lets you tweak sound profiles for personal preference.

Verdict:

For noise cancellation & immersive sound → WF-C710N (better ANC, richer bass).
For casual listening → WH-CH520 (good sound but no ANC).

3. Battery Life & Charging

WF-C710N

8.5 hours (ANC on) / 12 hours (ANC off) on a single charge.
30 hours total with the charging case.
Quick Charge: 5 mins = 60 mins playback.

WH-CH520

50 hours of playback (no ANC drain).
Quick Charge: 3 mins = 1.5 hours playback.

Verdict:

For all-day use → WH-CH520 (50 hours is unbeatable).
For wireless convenience → WF-C710N (case extends battery life).

4. Call Quality & Connectivity

WF-C710N

AI-Enhanced Call Clarity: Uses 500 million voice samples to filter background noise.
Multi-Point Bluetooth: Connect to two devices simultaneously (e.g., phone + laptop).

WH-CH520

Built-in Mic: Decent for calls but struggles in noisy environments.
Bluetooth 5.2: Stable connection but no multi-point pairing.

Verdict:

For clear calls & multi-device use → WF-C710N (better mic tech).
For basic calls → WH-CH520 (works but not as refined).

5. Price & Availability

Both models excel in different ways—WF-C710N for active users, WH-CH520 for budget-conscious listeners. If ANC is a priority, the WF-C710N is the clear winner. But if you just need reliable, long-lasting headphones, the WH-CH520 is a great deal.
