If you want one hard case that fits the widest range of portable on-ear headphones — Sony, JBL, Bose, Audio-Technica and more — choose DigiCharge Hard Protective Carry; if you need a purple case built specifically around Beats Solo and Studio on-ear models with room for small accessories, choose Aproca Purple Headphone Case.
• DigiCharge Hard Protective Carry — biggest strength: an EVA hard shell with a soft lining and a very long compatibility list, so it covers most popular on-ear headphones from Sony, JBL, Bose, Beats, Avantree, OneOdio, Marshall and others.
• DigiCharge Hard Protective Carry — biggest trade-off: it's a general-fit case, so it doesn't have a Beats-specific cutout or an internal accessory pocket — you get protection and a carabiner, not a tailored interior.
• Aproca Purple Headphone Case — biggest strength: a purpose-built fit for Beats Solo3, Solo 4, Studio Pro and Studio3 on-ear headphones, plus a mesh pocket for small extras and a hand strap.
• Aproca Purple Headphone Case — biggest trade-off: the fit is narrow — it's designed around Beats on-ear models, so it's the wrong pick if your headphones aren't on that list.
• Who each is for: DigiCharge for anyone with mixed-brand on-ear headphones who wants one tough, clip-on travel case; Aproca for Beats owners who want a snug fit, a purple finish and a spot for cables or dongles.
The DigiCharge Hard Protective Carry is the case you buy when you don't want to think too hard about it. It's an EVA hard shell with a soft inner lining, and the whole point is shielding portable on-ear headphones from bumps, dust and scratches — at home on a shelf, in a backpack, or clipped to a bag. The zip closure is secure, the shell is described as shockproof and water-resistant, and there's a detachable carabiner for hooking it onto a belt loop or the outside of a daypack. That carabiner is the detail that makes it genuinely travel-friendly rather than just a box.
What really sets it apart is the compatibility list. It names Sony WH-CH520, WH-CH510, MDR-ZX110, MDR-ZX310, MDR-XB550AP and WH-XB700; JBL Tune 510BT, 520BT, 660NC, 670NC, Live 400BT, 460NC, 500BT and 650BTNC; Bose QuietComfort 35 II, QC25, QC15, SoundLink, SoundTrue AE2 and AE2w; Beats Solo Pro and Solo3; plus Avantree, OneOdio, Audio-Technica ATH-M40x/M60x/ANC500BT, Anker Soundcore, Shure Aonic 50, Marshall Major III/IV and Monitor II, and a handful of Philips and Betron models. It's also rated for a maximum compatible device size of 9 cm, which is the number to check against your own headphones if you're unsure.
I'd point this one at people who own more than one pair of on-ear headphones, or who switch brands, or who want a case they can clip to the outside of a bag and forget about. Skip it if you specifically own Beats Solo or Studio models and want a tailored interior with an accessory pocket and a hand strap — that's not what this case is built to do. It's a broad, rugged, no-fuss solution rather than a custom-fit one.
The Aproca Purple Headphone Case is a much more targeted product. It's made from high-density EVA with 1680D material, and it's designed specifically for Beats Solo3, Beats Solo 4, Beats Studio Pro and Beats Studio3 Wireless on-ear headphones. If that's the pair in your bag, the fit is the whole reason to buy it — a case shaped around one family of headphones holds them more securely than a general-purpose shell ever will.
The practical details are aimed at daily carry. There's a comfortable hand strap and a D-shaped buckle for clipping it on, a mesh pocket for accessories like a charging cable or an adapter, and a smooth double zipper that opens wide for easy packing. The purple finish with a striped pattern makes it easy to spot in a bag, which sounds trivial until you're digging through a dark backpack at an airport. Aproca describes the construction as durable and scratch-resistant, and the shell is hard rather than soft-sided.
This is for Beats owners who want a dedicated home for their headphones plus a small pocket for the bits that always go missing. Skip it if your headphones aren't Beats Solo or Studio models — the fit is narrow on purpose, and a case that's too specific can leave your actual headphones rattling or not fitting at all. Also note that it ships as an empty case only; anything shown alongside it in photos is for illustration.
• Best for mixed-brand headphone collections → DigiCharge Hard Protective Carry. Its compatibility list spans Sony, JBL, Bose, Beats, Audio-Technica, Marshall and more.
• Best for Beats Solo3 / Solo 4 / Studio Pro / Studio3 owners → Aproca Purple Headphone Case. It's built around that specific family of on-ear headphones.
• Best for carrying small accessories → Aproca Purple Headphone Case. The mesh pocket is the only internal storage either case offers.
• Best for clipping onto a bag or belt → DigiCharge Hard Protective Carry. The detachable carabiner is designed for exactly that.
• Best for grabbing quickly by hand → Aproca Purple Headphone Case. The hand strap and D-buckle make it easy to carry on its own.
• Best for a slim, straightforward shell → DigiCharge Hard Protective Carry. Compact and lightweight, with a secure zip and a 9 cm maximum compatible device size to check against.
• Best for standing out in a crowded bag → Aproca Purple Headphone Case. The purple striped finish is far easier to spot than a plain black shell.
• Best for water resistance → DigiCharge Hard Protective Carry. It's explicitly described as water-resistant, which matters if your bag sees rain.
In my opinion, the DigiCharge Hard Protective Carry is the smarter buy for most people, and it's the one I'd take. The reason is simple: it covers a huge range of portable on-ear headphones, so if you upgrade from a Sony WH-CH520 to a JBL Tune or a pair of Bose QC35 II, the case still works. Add the water-resistant shell and the carabiner and you've got a genuinely rugged travel case rather than a shelf ornament.
That said, if you own Beats Solo3, Solo 4, Studio Pro or Studio3 and want a snug, purpose-built home with an accessory pocket and a hand strap, the Aproca Purple Headphone Case is the better match for you — a tailored fit beats a universal one when the fit is right. Check the current price on Amazon for whichever one fits your headphones, and confirm your model appears in the compatibility list before you commit.
what are the best open ear headphones
Neither of these products is a pair of headphones — both are hard carry cases for storing and protecting them. So the answer here depends entirely on which headphones you own. What I can tell you from the specs is that the DigiCharge case names a far longer list of compatible models, including Sony, JBL, Bose, Audio-Technica and Marshall on-ear headphones, while the Aproca case is designed specifically for Beats Solo and Studio on-ear models.
are on ear headphones good
On-ear headphones are a popular choice for portable listening because they sit lighter on the head than many over-ear designs and are easy to toss in a bag. That's exactly why a hard case makes sense for them: both the DigiCharge and Aproca cases use a hard EVA shell to protect against bumps, drops, dust and scratches, and both are designed to keep on-ear headphones secure while travelling or outdoors.
are open ear headphones good
Open-ear headphones are a different category from the on-ear models these two cases are built for, so neither case is designed around them. If you're shopping for a case, the practical question isn't open versus on-ear — it's whether your exact model is listed. The DigiCharge case covers a much broader set of on-ear models, while the Aproca case is limited to Beats Solo3, Solo 4, Studio Pro and Studio3.
what are the best in-ear headphones
In-ear headphones are a separate product type again, and neither of these cases is sized or shaped for them — both are hard shells built around on-ear headphones. If you already own on-ear headphones, the deciding factor between these two is fit: the DigiCharge case suits a wide range of brands, while the Aproca case is tailored to Beats Solo and Studio models and adds a mesh accessory pocket.
