Sony WF-C510
The WF-C510 is Sony's entry ticket, and it's the rare budget bud that reviewers describe as sounding like a Sony rather than a compromise: crisp, detailed mids and highs with a punchy low end, plus DSEE upscaling for compressed streams and a proper EQ in the Sound Connect app. The buds are genuinely tiny — among the smallest cases and lightest fits in the class — and owners who've worn them cycling and at the gym say they stay planted and shrug off sweat and rain despite the modest IPX4 rating. You get real multipoint for phone-plus-laptop switching, an Ambient Sound transparency mode with Voice Focus, and physical buttons instead of finicky touch panels. The trade-offs are clear-eyed ones: there's no ANC at all, no wireless charging, and while 11 hours per charge is excellent, the slim case only holds one extra charge for 22 total — the weakest case stamina in this price range. A 5-minute quick charge buying an hour of playback softens that. Codec support stops at SBC and AAC, so no LDAC hi-res here. If you want the most refined sound and smallest footprint under $50 and can live without noise cancelling, this is the pick; if you need ANC, look at the P30i or JBuds ANC 3 instead.

Owner Insights(70 discussions)
The WF-C510 is the budget earbud with a big-brand pedigree, and owner sentiment is among the most positive in the sub-$60 class - it took a What Hi-Fi? award and holds roughly 90%+ positive owner sentiment for a simple reason: it does the fundamentals better than anything near its price. The buds are Sony's smallest ever, the tuning is clean and balanced rather than bass-bombed, and the 10-11 hour per-charge battery is legitimately double the budget-class norm. For small-eared listeners in particular, this and the TOZO A1 Mini are the two names that come up constantly - with the Sony being the one that also sounds genuinely good.
Daily life with them is defined by reliability: physical buttons that always register (though pressing them nudges the bud deeper into your ear - the one ergonomic gripe), multipoint that owners call a game changer, and a just-works Bluetooth connection. The trade-offs are clear-eyed budget cuts rather than flaws. There's no ANC, the case adds only one recharge for 22 total hours, and the mic - fine in a quiet room - lets background noise compete with your voice and gives up entirely in wind. Swapping the stock tips unlocks noticeably better sound, a cheap upgrade most owners recommend.
Buy the WF-C510 if you want the best-sounding, most reliable non-ANC buds under $60, especially with small ears. If you need ANC, the conversation changes: the Soundcore Space A40 (~$50) or JLab JBuds ANC 3 (~$60) add noise cancelling but give up the Sony's sound refinement and monster per-charge battery, and Sony's own WF-C710N (~$100) is the in-family ANC step-up. Against the $20-30 crowd (A20i, P30i), the extra $20 buys audibly better sound, multipoint, and double the battery - one of the easier upsells owners endorse.
Pros
- +Sony's smallest earbuds ever, and it shows - light, low-pressure buds that small-eared owners single out as one of the few pairs that fit without ache
- +Best-in-class per-charge battery: 10.5-11 hours measured, roughly double what most budget buds deliver - a full day on one charge
- +Sound quality punches well above the $45-60 price - balanced, clean Sony tuning that owners call impressive for the cost, with EQ in the Sound Connect app
- +Physical buttons instead of touch controls - owners cite them as genuinely more reliable, no phantom taps in rain or with wet fingers
- +Multipoint connectivity at a budget price, which owners call a game changer for phone-plus-laptop use
- +Owner reliability reputation is strong - runners report them surviving heavy rain and sweat (IPX4), and long-term reports describe them as simply dependable
- +Ambient Sound passthrough mode included despite the budget price
Cons
- −No ANC at all - the single biggest reason owners step up a tier; passive isolation is decent but won't tame planes or subways
- −The case only holds one extra charge (22 hours total) - the flip side of the huge per-bud battery, and stingy next to 30-45-hour rival cases
- −Mic is quiet-room-only: clear indoors, but background chatter competes with your voice and wind completely overwhelms it outdoors
- −The physical buttons are slightly too big - pressing them pushes the bud deeper into your ear, which some owners find uncomfortable
- −Stock ear tips undersell the sound - several owners found the tuning only clicked after swapping to aftermarket tips
- −No wireless charging and SBC/AAC only - no aptX or LDAC at this tier
- −Case is small but plasticky, and there's no ear-hook or fin option for hard workouts

Sony's WF-C710N fixes the two loudest complaints about the beloved WF-C700N: it adds multipoint and touch controls, and stretches ANC battery life to 8.5 hours. The translucent Glass Blue finish became a minor social-media phenomenon, and the ANC — with dual noise sensors — is comfortably among the best in the sub-$100 tier when you catch it on sale from its $120 list. The stingy parts are very Sony: SBC/AAC only (no LDAC on a Sony bud at this price still stings), no wireless charging, no spatial audio, and the buds grew slightly chunkier than the C700N, which smaller ears notice on long sessions. The Sound Connect app is feature-rich but pushy about accounts and notifications. Mic quality is average outdoors in wind. Amazon review volume is still building since the 2025 launch, but sentiment tracks the C700N's strong reputation.

Still the all-rounder to beat for Android users, especially now that the XM6's arrival keeps pushing the price down. The 8.4mm Dynamic Driver X sounds rich and warm out of the box, LDAC delivers genuine hi-res from a phone, and the foam-ish tips seal so well that ANC feels stronger than it measures. Eight hours with noise canceling on is excellent, and 3 minutes in the case buys an hour. The consensus owner complaints are real, though: call quality falls apart in wind, the polished case scratches if you look at it wrong, and a vocal minority reports one bud draining faster than the other after a year-plus. Multipoint works but disables LDAC. The Headphones Connect app EQ is powerful once you find the settings buried three menus deep. IPX4 is fine for gym sweat, nothing more.

Sony's February 2026 flagship, and the new benchmark most earbuds get measured against. The QN3e processor cuts roughly 25% more noise than the XM5, and owners consistently rank the ANC at or above Bose while praising the richer, more customizable sound — the 8.4mm driver got a new dual-material diaphragm and 32-bit processing. Eight hours with noise canceling on is still best-in-class, the pill-shaped body is 11% slimmer with a matte finish that grips better than the XM5's slippery gloss, and multipoint plus LDAC plus LC3 covers every connection scenario. The honest caveats: the $330 list price is $30 over what the XM5 launched at (street has already slipped to ~$298), and fit remains the Sony gamble — the buds are still chunky at 6.5g each, and a real minority of owners just can't get them comfortable. Early owners also echo a familiar Sony worry: this line has a history of battery degradation complaints, and it's too soon to know if the XM6 fixed it. IPX4 is gym-only water resistance. If the XM5 fit you, these are the safe premium pick; if it didn't, nothing about the shape fundamentally changed.
