How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life, active noise cancelling and a fit that blocks out the world, choose JBL Tune 230NC; if you need an open-ear design that keeps you aware of your surroundings and stays comfortable for hours, choose Sony. That's the short version. The longer version matters a lot though, especially if you're shopping true wireless earbuds for seniors, where fit, volume clarity and how easy a bud is to live with all day matter more than spec-sheet bragging rights.
• JBL Tune 230NC — biggest strength: Up to 40 hours of total battery life (10 hours in the buds, 30 in the case) with Active Noise Cancelling and IPX4 sweat and water resistance. It seals your ear canal and shuts the world out.
• JBL Tune 230NC — biggest trade-off: That sealed, in-ear stick design means you're cut off from your surroundings unless you switch on Ambient Aware, and fit depends heavily on getting the right tip size.
• Sony — biggest strength: An open-ring, open-ear design with Air Fitting Supporters built for all-day comfort, plus an 11mm ring driver tuned for clear mid and high frequencies.
• Sony — biggest trade-off: Up to 22 hours of battery life (vs 40), Bluetooth 5 instead of 5.2, and it's a certified refurbished unit with a 90-day limited hardware warranty.
• Who JBL is for: Anyone who wants noise cancelled, long battery and a sweatproof bud for workouts or travel.
• Who Sony is for: Anyone who wants to stay aware of their surroundings and wear earbuds comfortably for hours on end.
The Tune 230NC is the "tune everything out" option. JBL built it around 10mm dynamic drivers pumping the brand's Pure Bass Sound, and the whole package is designed to seal your ear canal — a closed stick-style bud with silicone tips you can swap for a snugger fit. In my opinion, that sealing is the single biggest reason to pick it. Active Noise Cancelling actively reduces what's around you, and when you do want to hear something, Ambient Aware pipes the outside world back in and TalkThru lets you hold a quick conversation without pulling the buds out.
Battery is where it pulls clearly ahead. You get up to 40 hours total — roughly 10 hours in the buds plus 30 in the case — and if you're caught short, a 10-minute Speed Charge gets you about 2 hours of playtime. When noise cancelling is engaged, expect around 8 hours in the buds plus 24 in the case. For someone who wants to charge once and forget about it, that's a genuinely useful buffer.
Buy it if you want maximum battery, real noise cancelling, and a sweat-resistant bud for the gym, the commute or travel. Skip it if you need to stay fully aware of your surroundings at all times, or if you dislike the plugged-ear feeling of a sealed tip — that's the trade-off you're accepting here.
Sony: Who It's For
Sony's LinkBuds Open takes the opposite approach, and it's a deliberate one. Instead of sealing your ear, it uses an open-ring 11mm driver that sits in your ear without blocking it — so ambient sound comes through naturally. The newly developed Air Fitting Supporters are soft and ergonomic, and Sony's whole pitch is comfort for longer wear. If a sealed bud starts to feel pressurized or itchy after an hour, this is the design that fixes that.
Sound is handled by Sony's Integrated Processor V2 and that ring-shaped driver, tuned for well-balanced audio with clear mid and high ranges. It won't deliver the thumping low-end of a sealed bass-forward bud — that's physics, not a flaw — but voices, podcasts and acoustic material come through cleanly, which is exactly what a lot of listeners actually want. It also weighs 41g as a package versus 58g for the JBL set.
Battery is the honest weak point: up to 22 hours total, with a quick charge that gives you roughly 60 minutes of playback from a 3-minute top-up. Bluetooth here is version 5, not 5.2. Controls run through Sony's app rather than touch taps on the bud. The included accessories are the Air Fitting Supporters, a cable and a charging case.
Buy it if you want open-ear awareness, an all-day comfortable fit, and clear mid and high frequencies. Skip it if you need maximum battery, a sealed noise-cancelling fit, or you're uneasy about a refurbished unit with a 90-day limited warranty.
• Best for battery life → JBL Tune 230NC. Up to 40 hours total versus up to 22 for the Sony set.
• Best for blocking out noise → JBL Tune 230NC. Active Noise Cancelling with Ambient Aware and TalkThru, on a sealed in-ear design.
• Best for staying aware of your surroundings → Sony. The open-ring driver lets outside sound in by design.
• Best for all-day comfort → Sony. Air Fitting Supporters and an open-ear form factor built for long sessions.
• Best for workouts and bad weather → JBL Tune 230NC. IPX4 water resistance and sweatproofing.
• Best for podcasts, calls and voice clarity → Sony. Clear mid and high ranges from the Integrated Processor V2.
• Best for call handling → JBL Tune 230NC. Four microphones for stereo hands-free calls.
• Best for buyers wary of refurbished units → JBL Tune 230NC. The Sony option is certified refurbished with a 90-day limited warranty.
• Best for seniors who want simplicity and long runtime → JBL Tune 230NC. Fewer charges, sealed fit that holds steady, and touch controls.
If I were buying for myself, I'd take the JBL Tune 230NC. The 40-hour battery, real active noise cancelling and IPX4 sweat resistance cover more of my day, and for the true wireless earbuds for seniors use case specifically, charging less often and getting a secure sealed fit is genuinely easier to live with. I'd only switch to the Sony LinkBuds Open if open-ear awareness and all-day comfort were my top priorities — and in that case I'd accept the shorter 22-hour battery and the refurbished unit with its 90-day limited warranty. In my opinion, the JBL is the safer all-rounder; the Sony is the specialist. And since prices move, check the current price on Amazon before you commit.
how to connect true wireless earbuds
Put the buds in your ears, then open your phone's Bluetooth settings and select the earbuds from the list of available devices. Both the JBL Tune 230NC (Bluetooth 5.2) and the Sony LinkBuds Open (Bluetooth 5) pair over standard Bluetooth with no headphone jack involved. The JBL set ships with a USB-C charging cable, eartips and a user manual to walk you through setup.
how to pair true wireless earbuds
Pairing usually means taking the buds out of the charging case so they enter pairing mode, then confirming the connection on your device. The JBL Tune 230NC uses touch media controls on the bud itself, while the Sony LinkBuds Open routes controls through Sony's app. Once paired, both reconnect automatically the next time you take them out.
how to use true wireless earbuds
Wear them with the tips that fit most snugly — JBL specifically notes that a poor tip fit hurts both sound quality and call performance. Use the touch controls on the JBL for media, or Sony's app for the LinkBuds Open. On the JBL you can also switch between Active Noise Cancelling, Ambient Aware and TalkThru depending on whether you want to block sound or hear it.
how to bluetooth true wireless earbuds
Turn on Bluetooth on your phone or tablet, then select the earbuds from the device list. Both models here are true wireless with no jack, so Bluetooth is the only connection method. If pairing stalls, charge both the buds and the case first, since a low battery can stop a bud from entering pairing mode.
