Wondering what fits in the HiBy BA04 organizer? See how the 18.5×11×3.5 cm case stores IEMs, DAPs, cables, and more—plus practical packing tips.
Quick Answer
The HiBy Accessories Organizer BA04 fits a compact DAP, a pair of IEMs, a cable, and a small adapter—but not a full-size smartphone or bulky power bank. Use the flat compartments to separate gear and avoid overstuffing the 18.5×11×3.5 cm case.
Why Size and Layout Matter
The BA04's 18.5×11×3.5 cm footprint is slim enough to slip into a backpack or tote, but that depth is the real constraint. You can stack flat items, yet anything thicker than about 3 cm—like a chunky power bank or a DAP with a thick case—will strain the zipper.
Because the organizer has multiple compartments, you can keep cables and adapters from scratching your DAP or IEM shells. That separation is what makes it a practical choice for daily carry, not just storage at home.
Trade-Offs to Keep in Mind
The BA04 is not a hard case. If you need crush protection for a high-end DAP, a padded hard shell is safer. The organizer protects against scratches and dust, not impacts.
There is no official spec for the number of compartments or internal pockets. So the exact layout may vary; check the product photos or your unit to confirm how many sections you have before packing.
Packing Answers for the BA04
- Can it fit a DAP?
- Yes, most compact DAPs (like the HiBy R3 Pro II or similar) fit easily in the main compartment. For larger DAPs, measure the width and depth first; if it's thicker than 3 cm, it may not close comfortably. Measure your DAP's thickness before buying if you plan to carry it in the case.
- Can it store IEMs?
- Yes, a pair of IEMs with a short cable fits in the main area or a dedicated pocket. Just coil the cable loosely to avoid sharp bends, and keep the earpieces separated to prevent scratches. Use a small pouch for the IEMs if you want extra scratch protection.
- Can it hold a smartphone?
- A standard smartphone (around 16×7.5 cm) can fit in the main compartment, but it will take up most of the space. If you need to carry a DAP plus a phone, you'll have little room for cables or adapters. Consider whether you really need to carry both; the BA04 is best for one primary device plus accessories.
- What about cables and adapters?
- The organizer has space for cables and adapters, but keep them coiled and use the separate compartments to avoid tangling. A USB-C cable and a small dongle adapter fit without issue. Use small rubber bands or velcro ties to keep cables tidy.
- What won't fit?
- A large power bank, a DAP with a thick protective case, or over-ear headphones won't fit. The 3.5 cm depth is the limiting factor. If you need to carry a power bank, look for a larger organizer or a separate pouch.
