• LG Electronics Tone Infinim — biggest strength: marathon battery figures (up to 17 hours talk, up to 14 hours music, up to 23 days standby), Harman Kardon Signature Sound tuning and retractable earbuds that spool back into the neckband.
• LG Electronics Tone Infinim — biggest trade-off: no noise cancelling at all, and Bluetooth 3 with no aptX HD or high-resolution codec support.
• Sony Noise Cancelling — biggest strength: Digital Noise Cancelling with Atmospheric Pressure Optimizing, plus aptX HD, LDAC and DSEE HX for higher-quality wireless audio.
• Sony Noise Cancelling — biggest trade-off: up to 10 hours of battery with wireless noise cancelling on — roughly two-thirds less music time than the LG on paper.
• Pick the LG if your day is calls, podcasts and all-day wear and you want the cord-tangle problem solved.
• Pick the Sony if you fly, commute in loud places, or care most about codec quality and adjustable ambient sound.
The Tone Infinim (HBS-900) is a behind-neck Bluetooth headset with a very specific personality. The earbuds retract into the band when you're not listening, which means no dangling wires and no untangling ritual every time you pull it out of a bag. That one design choice is why a lot of people stay loyal to this shape. Add the jog button for one-touch volume and track control, and the whole thing is built to be operated without looking.
Audio-wise, LG leans on Harman Kardon Signature Sound, a dynamic driver and a stated frequency range of 20Hz–48kHz, with aptX compatibility for lifelike playback over Bluetooth. The spec sheet also lists HD voice and a MEMS microphone for calls, plus the Tone & Talk app on Android for SMS reading, time alerts, battery status alerts and vibration on/off. In my opinion, that app layer is the underrated part: it's a headset that quietly tells you things instead of making you check your phone.
The battery numbers are the headline. Up to 17 hours of talk time, up to 14 hours of music playback and up to 23 days of standby from a single charge is a genuinely long-window device — the kind you can wear through a workday plus a commute and charge overnight without anxiety. Weight is 3.2 ounces, the finish is metal-and-plastic in gold, and the earpiece shape is an angled ear hook or wing, which is a design that stays put during movement but is not for everyone's ear anatomy.
Sony Noise Cancelling: Who It's For
The Sony WI1000X/B is the opposite philosophy: it accepts shorter battery life in exchange for actively managing the noise around you. Digital Noise Cancelling with Atmospheric Pressure Optimizing is tuned for air travel specifically, compensating for cabin pressure changes at altitude. That's a feature you notice on hour six of a long-haul flight, not in a spec table.
Sony's other differentiator is codec and processing support. It lists SBC, AAC, LDAC, aptX and aptX HD, with DSEE HX upscaling compressed audio, S-Master HX reducing distortion, and LDAC pushing up to 990 kbps at 96 kHz sampling. The driver setup is a 9mm dynamic driver paired with a balanced armature driver, working together to keep response steady across the range. If you stream from a service that supports higher-bitrate transmission, this is the headset that can actually take advantage of it.
Then there's the software side. Sony's Headphones Connect app on Android and iOS handles Smart Listening by Adaptive Sound Control, which detects whether you're travelling, walking or waiting and adjusts ambient sound automatically. Ambient Sound mode lets you hear announcements or a barista without pulling the buds out. The headset is also optimized for the Google Assistant after an update, and hands-free calling includes vibration notification. Bluetooth is 4.1, there's a 3.5mm jack for wired listening, and weight is 2.5 ounces — lighter than the LG on paper.
Who should buy it: frequent flyers, commuters on loud transit, and listeners who care about aptX HD/LDAC quality and want to tune ambient sound to their environment. Who should skip it: people who want to charge once every few days, or who find app-dependent controls fiddly. Battery is up to 10 hours with wireless noise cancelling — that's a single long day, not a week.
• Best for noise cancelling → Sony Noise Cancelling. Digital Noise Cancelling with Atmospheric Pressure Optimizing, versus no noise control on the LG.
• Best for battery life → LG Electronics Tone Infinim. Up to 14 hours music and up to 17 hours talk, against Sony's up to 10 hours with ANC on.
• Best for aptX HD earbuds → Sony Noise Cancelling. aptX HD and LDAC are both listed; the LG supports aptX but not aptX HD.
• Best for cable-free storage → LG Electronics Tone Infinim. Retractable earbuds wind back into the neckband.
• Best for flying → Sony Noise Cancelling. The pressure-optimizing noise cancelling is explicitly aimed at in-flight listening.
• Best for call-heavy days → LG Electronics Tone Infinim. HD voice, a MEMS microphone and up to 17 hours of talk time.
• Best for commuters who need to hear the world → Sony Noise Cancelling. Ambient Sound mode and Adaptive Sound Control handle that automatically.
• Best for wired backup → Sony Noise Cancelling. It has a 3.5mm jack; the LG is wireless only.
• Best for app-light simplicity → LG Electronics Tone Infinim. The Tone & Talk extras are alerts, not a control dependency.
If I had to pick one, I'd buy the Sony Noise Cancelling. In my opinion, noise cancelling plus aptX HD, LDAC and DSEE HX is the combination that matters most in 2026 — planes, trains and open offices aren't getting quieter, and the codec support means better sound from the same streaming subscription. The up-to-10-hour battery is the real cost, and I'd accept it.
That said, the LG Electronics Tone Infinim is not the consolation prize. If your listening is calls and playlists rather than flights, the retractable design and the far longer battery figures make it the more relaxing device to own. Check the current price on Amazon for both before you commit, since the gap between them changes what "worth it" means.
FAQ
Sony Noise Cancelling does — its supported audio formats list SBC, AAC, LDAC, aptX and aptX HD. LG Electronics Tone Infinim lists aptX compatibility but not aptX HD, so it delivers aptX-grade wireless audio rather than the higher-bitrate variant.
LG lists up to 17 hours of talk time, up to 14 hours of music playback and up to 23 days of standby. That's roughly 40% more music time than the Sony's up-to-10-hour figure with noise cancelling on.
No. Its noise control field is listed as None, and it relies on an in-ear angled ear hook fit for passive isolation only. If blocking engine noise or office chatter is your priority, the Sony's active noise cancelling is the one that addresses it.
