How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a protective silicone shell that adds wireless charging and a clip to your Bose Ultra Open Earbuds case, choose Bose Open Earbuds; if you need a full replacement charging case for your 4th-generation AirPods, choose CCAN Charging Case Compatible.
• Bose Open Earbuds — biggest strength: it upgrades the Ultra Open Earbuds case to wireless charging while wrapping it in soft silicone and adding a carabiner for clipping to a bag.
• Bose Open Earbuds — biggest trade-off: it is an accessory, not a case replacement, and the silicone is not water resistant, so it is a poor fit for heavy rain or sweaty workouts.
• CCAN Charging Case Compatible — biggest strength: it replaces a lost or dead AirPods 4th-gen case and supports both USB-C and wireless charging with fast-charge figures and an LED readout.
• CCAN Charging Case Compatible — biggest trade-off: it is locked to AirPods 4th-gen (A3053/A3050/A3054/A3056/A3057) only, and neither the earbuds nor a Type-C cable come in the box.
• Who each is for — Bose Open Earbuds if you already own Ultra Open Earbuds and want wireless charging plus drop protection; CCAN if you own 4th-gen AirPods and need a working case again.
This is a case cover, not a pair of earbuds, and that distinction matters more than anything else on this page. The Bose Ultra Open Earbuds Wireless Charging Case Cover slips over the existing charging case for Bose Ultra Open Earbuds and adds two things the bare case does not give you: wireless charging and physical protection. The silicone shell is there to soak up the scratches and scuffs that come from living in a pocket or the bottom of a bag, and the built-in carabiner lets you clip the whole thing to a backpack strap, belt loop or tote so it stops disappearing into the void.
The design choices are consistent with that job. It is a soft silicone enclosure in black, with a solid theme, weighing about 1.44 ounces and measuring roughly 1.34 x 3.01 x 2.46 inches — small enough to ride along without noticing it. You get the case cover, the carabiner and a user manual in the pack, and it carries a one-year manufacturer warranty. The compatibility line is short and absolute: it fits Bose Ultra Open Earbuds, and nothing else.
Buy it if you already own Ultra Open Earbuds, you charge on a wireless pad, and you want the case to survive real life with a clip so it stays attached to your gear. Skip it if you were hoping for a replacement case for earbuds that went missing — this does not do that. Also skip it if you need water resistance: the sheet says plainly it is not water resistant, so a downpour or a soaked gym bag is not what this cover was built for. That is the honest trade-off, and it is worth knowing before you buy.
The CCAN case solves a completely different problem: your AirPods 4th-gen case is gone, damaged or no longer holding a charge, and you want to keep using the earbuds you already have. It is a replacement charging case for the 4th generation only, and the fit list is specific — model numbers A3053, A3050, A3054, A3056, A3055 and A3057. It will not work with 1st, 2nd, 3rd generation or Pro models, so check your model number before anything else.
The practical details are where it earns its place. It charges two ways, over Type-C or on a wireless pad, and the fast-charge figures are stated clearly: five minutes of charging yields about an hour of listening, a fully drained pair of earbuds takes roughly 30 minutes to top up, and the case itself needs about 2.5 hours to refill. A clear LED indicator shows the case's remaining capacity so you are not guessing. Pairing is handled with a single button press, which wakes Bluetooth and lets your phone recognize the case and show battery status.
Two things to plan around. First, the box contains the wireless charging case only — no earbuds and no Type-C cable, so you need a cable already. Second, the shell is hard plastic, which protects the case itself but is a different feel from soft silicone. Buy it if you own 4th-gen AirPods and want your setup working again with both charging options. Skip it if you own any other generation, or if you were looking for a protective cover rather than a functional replacement.
• Best for wireless charging an existing Bose case → Bose Open Earbuds. It adds wireless charging to the Ultra Open Earbuds case you already own.
• Best for reviving dead or lost AirPods 4th-gen → CCAN Charging Case Compatible. It is a full working replacement case, not a cover.
• Best for drop and scratch protection → Bose Open Earbuds. Soft silicone absorbs scuffs; the CCAN is hard plastic and protects differently.
• Best for carrying on your gear → Bose Open Earbuds. The carabiner clips to a bag or belt loop; the CCAN has no clip.
• Best for fast top-ups → CCAN Charging Case Compatible. One hour of listening from five minutes of charging is the standout figure here.
• Best for charging flexibility → CCAN Charging Case Compatible. It does Type-C and wireless; the Bose cover is about wireless charging for the case it wraps.
• Best for battery visibility → CCAN Charging Case Compatible. The LED indicator shows remaining case capacity at a glance.
• Best for wet or sweaty conditions → neither, honestly. The Bose cover is not water resistant, and the CCAN sheet makes no water-resistance claim either.
In my opinion, these two barely compete — they serve different owners, so the right answer depends entirely on what is sitting in your pocket. If you already have Bose Ultra Open Earbuds and you charge on a pad, I would buy the Bose Open Earbuds cover: wireless charging plus a carabiner plus scratch protection is a sensible, low-drama upgrade, as long as you accept it is not water resistant. If you have 4th-gen AirPods and no working case, I would buy the CCAN Charging Case Compatible instead, because a cover cannot fix a case that is gone. Check the current price on Amazon for whichever one matches your earbuds, and confirm your model number first.
No. It is a silicone cover for the Bose Ultra Open Earbuds charging case that adds wireless charging, scratch protection and a carabiner. It does not replace the case and it does not include earbuds.
No. It fits 4th-generation models A3053/A3050/A3054/A3056/A3055/A3057 only, and the listing states it is not compatible with 1st, 2nd, 3rd generation or Pro models.
No. You get the wireless charging case only. Earbuds and the Type-C cable are not included, so keep a cable on hand for wired charging.
The CCAN case claims about one hour of listening from five minutes of charging, roughly 30 minutes to fully charge drained earbuds, and about 2.5 hours to charge the case itself. The Bose cover is about adding wireless charging to your existing Ultra Open Earbuds case, and its sheet gives no charging-time figures.
