If you want a protective, wireless-charging accessory built specifically for your Bose Ultra Open Earbuds, choose Bose Open Earbuds; if you need a full replacement charging case for your AirPods 4th Generation, choose Yitonglian Charger Case Replacement. These two products look similar in a search bar, but they do completely different jobs — one dresses up a case you already own, the other replaces a case you've lost or broken. Getting them confused is the fastest way to waste a purchase, so let's break down what each one actually is.
• Bose Open Earbuds (the Wireless Charging Case Cover) — biggest strength: adds wireless charging plus a soft silicone shell and carabiner for the Bose Ultra Open Earbuds case. Biggest trade-off: it's a cover only, not a case replacement, and it isn't water resistant.
• Yitonglian Charger Case Replacement — biggest strength: a complete, hard-shell charging case for AirPods 4th Gen with a 450mAh battery, LED indicator and one-touch Bluetooth pairing. Biggest trade-off: it only fits 4th-generation models and ships without earbuds.
• Who each is for — Bose for someone who already owns the Ultra Open Earbuds and wants protection plus wireless charging; Yitonglian for an AirPods 4 owner who's missing a working case.
Bose's entry here is the Wireless Charging Case Cover for the Bose Ultra Open Earbuds, finished in black silicone. It's a soft, lightweight shell — the item weight is just 1.44 ounces, and it measures roughly 1.34 x 3.01 x 2.46 inches. In plain terms, it's a skin for the case you already have. It doesn't replace anything; it wraps around the existing Bose case and adds two things the bare case doesn't give you in one package: wireless charging and a carabiner.
The wireless charging part is the headline. If you've ever fumbled with a cable at your desk or bedside, dropping the case onto a charging pad is genuinely more convenient. The silicone shell also protects against the scratches and scuffs that come from a case rattling around in a bag or pocket. And the carabiner is a small but practical touch — clip it to a backpack loop, a belt loop or a gym bag strap and it stops disappearing into the bottom of your luggage.
Yitonglian Charger Case Replacement: Who It's For
The Yitonglian is a different animal entirely. It's a full replacement charging case for the AirPods 4th Generation, made from hard white plastic. You're not covering an existing case — you're replacing one that's lost, damaged or no longer holding a charge. Since it doesn't include earbuds, it only makes sense if you still have your AirPods but not a working case.
Compatibility is the thing to check first. Yitonglian states it fits the 4th-generation models A3053, A3050, A3054, A3056, A3055 and A3057 — and explicitly warns it's not compatible with the 1st, 2nd, Pro or 3rd generation. That's a narrow but useful target. If your model number is on that list, you're in business.
The battery is the real story. A 450mAh cell gives you up to three additional full charges for your earbuds, and Yitonglian says it can bring your earbuds to 100% in roughly 30 minutes while the case itself fully recharges in about 2.5 hours. For anyone who treats their earbuds as an all-day tool, that's the difference between a case that's a dead weight and one that actually extends your listening time. A clear LED indicator shows remaining capacity so you're not guessing, and one-touch Bluetooth pairing lets your phone recognize the case and display its battery status without a fuss.
Who should buy it? An AirPods 4 owner whose case is gone or failing, who wants a functioning case with solid backup power without hunting down an original. Who should skip it? Anyone with 1st, 2nd, 3rd-gen or Pro AirPods — it simply won't fit — and anyone who needs the earbuds too, since this is case-only.
• Best for wireless charging convenience → Bose Open Earbuds, which upgrades your existing Bose case to charge on a pad.
• Best for replacing a lost or broken case → Yitonglian Charger Case Replacement, a complete hard-shell case for AirPods 4th Gen.
• Best for backup battery power → Yitonglian, with its 450mAh battery and up to three extra full charges.
• Best for protection from scratches → Bose, whose soft silicone shell guards against scuffs and includes a carabiner.
• Best for quick top-ups → Yitonglian, which claims to reach 100% in about 30 minutes.
• Best for a specific device ecosystem → Bose for Bose Ultra Open Earbuds; Yitonglian for AirPods 4th Generation only.
• Best for pairing simplicity → Yitonglian, thanks to one-touch Bluetooth pairing and a visible LED power indicator.
• Best for a low-commitment upgrade → Bose, if you already own the earbuds and just want a nicer case setup.
In my opinion, if you own Bose Ultra Open Earbuds, buy the Bose Wireless Charging Case Cover — it's the clearly-matched accessory for your earbuds and adds wireless charging, grip and a carabiner without overcomplicating anything. If, instead, you own AirPods 4th Gen and your case is lost or failing, buy the Yitonglian Charger Case Replacement, because it's the one that actually restores a working case with real backup battery. The deciding question isn't which is "better" — it's which pair of earbuds is in your pocket. Match the product to your earbuds and you'll be happy either way. Check the current price on Amazon before you commit, since both are budget-friendly accessories where a quick look pays off.
FAQ
No. Yitonglian states it fits only 4th-generation models (A3053, A3050, A3054, A3056, A3055, A3057) and is not compatible with 1st, 2nd, 3rd-gen or Pro models. Check your model number before buying.
No — it's a cover that wraps around your existing Bose Ultra Open Earbuds case. It doesn't include the case itself, and Bose lists it as not water resistant.
The Yitonglian, by design — its 450mAh battery provides up to three additional full charges and tops your earbuds to 100% in roughly 30 minutes. The Bose cover focuses on wireless charging and protection, not extra capacity.
