Our editorial verdict, built on published evidence: the Sony LinkBuds Open pair 9.5-hour measured battery life — past Sony's 8-hour claim — with comfortable open-ring wear, if your ears fit them. Sound is mid-pack for open ears, and noise simply passes through. The price stings; check the current price on Amazon, since the original LinkBuds often cost far less.
— THE VERDICT · JUDGEANY EDITORSAn open ring, and a familiar idea
Sony's LinkBuds Open (WF-L910) launched in October 2024 as the successor to the 2022 LinkBuds — the donut-shaped earbuds that made open-ring listening mainstream. The premise is unchanged: an 11mm ring-shaped driver sits in front of your ear canal rather than inside it, so your music and the world around you arrive at the same time. What changed is everything around the ring — a slimmer body, soft Air Fitting Supporters meant to reduce pressure over long wear, the Integrated Processor V2 borrowed from the WF-1000XM5, and LE Audio over LC3. This review is built from published reviews and owner feedback. We don't run a test lab: every measurement below belongs to the outlet that published it, and the score is our editorial judgment based on that public evidence.
Design and comfort: light, with an asterisk
The spec sheet is kind to the LinkBuds Open: each bud weighs about 5.1 g with the Air Fitting Supporters, and the case is a 30.6 g pebble with a marble-patterned lid. Sony rates the buds "IPX4 equivalent" — and the word equivalent matters; as SoundGuys points out, there is no formal IP rating, so think sweat and rain, not swimming. What Hi-Fi? found comfort exceptional, among the best it had experienced from an open set, and comfort is the one dimension the reviews broadly agree on. The asterisk is fit: it depends heavily on ear shape. SoundGuys' reviewer found the fin comfortable yet spent the review worried the buds would launch out during quick movement, while DeviceDaily's tester found the hard plastic ring uncomfortable after about 45 minutes. For hard-to-fit ears, this dimension decides the purchase.
Sound: decent for open ears, modest everywhere else
Sound quality is where expectations need calibrating to the category. SoundGuys' listening panel gave the LinkBuds Open a mean opinion score of 2.7 out of 5 — just under the 2.9 open-ear average, and behind the Nothing Ear (Open), the current benchmark. Sub-bass is essentially absent, the highs run a touch hot, and maximum volume is a little low. TechRadar disagrees at 3.5/5, calling the bass "fairly meaty" for the category with clear mids — a genuine conflict, stated plainly. What Hi-Fi? lands between them at 3/5. Either way the takeaway holds: these are fine for podcasts, calls, and background music while you stay aware of your surroundings, not the pick for critical or bass-heavy listening.
Battery: the number that surprised reviewers
Sony claims 8 hours per charge and 22 hours total with the case. SoundGuys' standardized endurance test came back at 9 hours 30 minutes — past Sony's own claim, a result you rarely see for any true wireless earbuds. Mezha's real-world run, mostly at maximum volume, managed around 7 hours, close to the claim under punishment. A 3-minute charge adds 60 minutes of playback, a full bud recharge takes about 1.5 hours, and the case about 2.5 hours over USB-C. The gap in the spec sheet: no wireless charging, flagged by SoundGuys and others at this price.
Features: Sony's full software stack
TechRadar's 4.5/5 features score is the highest single dimension any major outlet gave these earbuds, and the feature list earns it. You get LE Audio with LC3 for low latency, genuinely smooth multipoint switching in SoundGuys' testing, Wide Area Tap (tap your cheek, not the bud), Speak to Chat, Adaptive Volume Control that adjusts to your surroundings, and 360 Reality Audio with head tracking. The companion Sound Connect app handles EQ and firmware. The weak link is calls: SoundGuys ran microphone demos across office, street, wind, and reverberant conditions, and found the mic "a little on the crummy side" — usable, but wind hits it hard. Codecs are SBC, AAC, and LC3; there is no LDAC, so Sony's own hi-res badge stays off these.
The verdict on value
The recurring complaint across outlets is price. SoundGuys lists the MSRP at $229.99, TechRadar at $199, and both score value modestly — TechRadar's 3/5 notes the price is high "against similar quality rivals." What Hi-Fi? goes further, pointing readers at the original LinkBuds, which sell for substantially less and do the same job for most people. Colors include Black, White, and Violet, the last a collaboration with Olivia Rodrigo with custom EQ tuned by the artist and her producer. If awareness-first listening is your daily mode and your ears fit the ring, these are among the most comfortable ways to get it — but check the current price on Amazon before paying anywhere near the launch price.
