How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the more feature-dense everyday earbuds with adaptive noise cancellation, LDAC and Hi-Res Audio, choose Anker Soundcore Liberty 5; if you need a Star Wars Darth Vader limited-edition pair with magnetic on/off power saving, Qi wireless charging and multipoint, choose Audio-Technica ATH-CKS50TW2DV.
• Anker Soundcore Liberty 5 — biggest strength: Adaptive ANC 3.0 that re-tunes every 0.3 seconds, plus LDAC and Hi-Res Audio for detail-rich listening.
• Anker Soundcore Liberty 5 — biggest trade-off: Its spec sheet leans on ANC and codec features rather than exotic extras like wireless charging or a collectible design.
• Audio-Technica ATH-CKS50TW2DV — biggest strength: The Star Wars Darth Vader theme runs through the audio alerts themselves, and magnetic on/off power saving is genuinely clever.
• Audio-Technica ATH-CKS50TW2DV — biggest trade-off: No LDAC or Hi-Res Audio here, and the noise-cancelling field is listed as "None" in the controls data even though a button-driven hybrid ANC mode is described.
• Who each pick is for: Liberty 5 for commuters and listeners chasing quiet and codec quality; the ATH-CKS50TW2DV for Star Wars fans and anyone who wants a themed, wireless-charging pair.
The Liberty 5 is built around the idea that your environment keeps changing, so the earbuds should keep changing with it. Adaptive ANC 3.0 recalculates every 0.3 seconds, and the acoustic cavity is tuned specifically to dampen human voices twice as effectively. That is a very specific claim, and it points at a very specific use case: trains, subways, open-plan offices, anywhere the noise around you is people talking rather than a steady engine hum.
On the listening side, the hardware list is unusually detailed for this class. Wool paper diaphragms, bass-enhancing tubes, a 9.2 mm balanced armature driver, LDAC and Hi-Res Audio support all point to a tuning philosophy that favors nuance over blunt force. There are also custom Dolby Audio modes for music, movies and podcasts, six microphones with AI noise cancellation and a wind-resistant algorithm for calls, and six ear tip sizes (XXS through XL) with size M pre-installed — which matters more than people think, because a proper seal is what makes ANC actually work.
Buy it if you commute in noisy, voice-heavy environments, take a lot of calls on the move, or care about LDAC and Hi-Res Audio as a baseline requirement. Skip it if you want a themed, collectible design, wireless charging, or the magnetic power-saving trick — none of those are part of this package. Battery is up to 12 hours per charge and 48 hours total in normal mode, dropping to 8 hours per charge and 32 hours total with ANC on, with a 10-minute quick charge giving 5 hours. Note that this listing is a renewed unit with a 90-day limited warranty, so factor that in.
This one is a different proposition entirely. The ATH-CKS50TW2DV is a limited-edition Star Wars Darth Vader model, and the theme is not just cosmetic — the earbuds play character-related audio alerts, including the iconic breathing and lightsaber sounds, for power on/off, Bluetooth connect/disconnect and low battery. That is either the whole reason you are here or the whole reason you are not.
The engineering underneath is more interesting than the theme suggests. Magnetic Switch technology lets you power the earbuds on and off just by joining or decoupling the built-in magnets, which conserves battery when you are out without the case. Proprietary 9 mm drivers promise full-range audio with enhanced bass. Multipoint pairing holds two Bluetooth devices at once. A customizable multifunction button handles playback, volume, calls, voice assistant and ambience. And the earbuds work with Qi wireless chargers, which is a convenience the Liberty 5 does not offer.
Battery is 25 hours per charge plus 40 more from the case; with noise cancelling on, that becomes 15 hours plus 25. A 5-minute quick charge gives up to 90 minutes. There is a button-activated hybrid ANC mode with feedforward and feedback processing, plus hear-through and talk-through ambience options that also work during calls. Dust and water protection is rated IP5X and IPX5 — protected against dust and water jets, but not fully waterproof, so keep them out of the bath. Buy it if you want the Vader theme, wireless charging, or the magnetic power trick. Skip it if LDAC and Hi-Res Audio are non-negotiable.
Side-by-Side: Which Should You Choose?
• Best for adaptive noise cancellation → Anker Soundcore Liberty 5. ANC 3.0 adjusts every 0.3 seconds and is tuned to block voices twice as effectively.
• Best for battery per charge → Anker Soundcore Liberty 5. Up to 12 hours normal / 8 hours with ANC, versus 25 / 15 on the Vader model — the Anker figure is per-charge, the Audio-Technica figure is also per-charge, so match your own listening pattern to it.
• Best for total battery with the case → Audio-Technica ATH-CKS50TW2DV. 65 hours total normal or 40 with ANC, against 48 normal or 32 with ANC on the Liberty 5.
• Best for calls and voice pickup → Anker Soundcore Liberty 5. Six mics, AI noise cancellation and a wind-resistant algorithm.
• Best for charging convenience → Audio-Technica ATH-CKS50TW2DV. Qi wireless charging support and the magnetic on/off power-saving trick.
• Best for a themed, collectible design → Audio-Technica ATH-CKS50TW2DV. The Darth Vader alerts are unique to this model.
• Best for fit options out of the box → Anker Soundcore Liberty 5. Six ear tip sizes from XXS to XL, with M pre-installed.
In my opinion, I would buy the Anker Soundcore Liberty 5. The reason is simple: it covers more of what most people actually do with earbuds day to day — adaptive ANC tuned for voices, LDAC and Hi-Res Audio, six-mic calls and six ear tip sizes. The Audio-Technica ATH-CKS50TW2DV is the better pick if the Darth Vader theme, Qi wireless charging or the magnetic power trick genuinely matter to you, and its total battery with the case is longer. But if you are choosing on core audio and noise-cancelling features rather than theme, the Liberty 5 is my recommendation.
what is ldac headphones
LDAC is a high-quality Bluetooth audio codec, and "LDAC headphones" simply means a pair that supports it. In this comparison, the Anker Soundcore Liberty 5 lists LDAC and Hi-Res Audio among its features, while the Audio-Technica ATH-CKS50TW2DV does not list LDAC at all.

what is ldac codec in headphones
The LDAC codec is a Bluetooth encoding method focused on preserving more musical detail during wireless playback. If that matters to you, the Liberty 5 is the one to look at here; the ATH-CKS50TW2DV focuses instead on its magnetic power-saving, multipoint and Vader-themed alerts.
Do these earbuds have noise cancelling?
The Liberty 5 has Adaptive ANC 3.0 that re-tunes every 0.3 seconds, with 8 hours per charge and 32 hours total with ANC on. The ATH-CKS50TW2DV describes a button-activated hybrid ANC mode with 15 hours per charge and 25 more from the case, though its controls field lists noise control as "None."
