• INHARD Replacement Beats Solo4 — biggest strength: a dedicated two-pad kit for the Beats Solo 4 with PU leather, memory foam, left/right markings and a plastic stick for tool-free installation in about five minutes.
• INHARD Replacement Beats Solo4 — biggest trade-off: it makes no sound on its own. It only works if you already own Beats Solo 4 headphones, and it's a single-purpose part with no warranty listed.
• Navly Headband — biggest strength: up to 12 hours of playback from a 2-hour charge, Bluetooth pairing, a hidden mic for calls, and a machine-washable fabric band with a 0.3" thin control panel that's built for side sleepers.
• Navly Headband — biggest trade-off: no active noise cancellation — it relies on passive muffling from the fabric and fit — and it isn't a replacement part for anything.
• Choose INHARD Replacement Beats Solo4 if your Solo 4 pads are flaking, flat or uncomfortable and you want the headphones back to comfortable.
• Choose Navly Headband if you want private audio while lying down, traveling or falling asleep without jamming earbuds into your ears.
This is a repair kit, plain and simple. INHARD sells a pair of replacement ear pads sized for the Beats Solo 4 on-ear headphones, made from PU leather over memory foam. The leather is described as skin-friendly and breathable, and the memory foam is meant to mould to the shape of your ear over time rather than staying stiff out of the box. There's a slim dustproof net inside each pad to keep the driver area cleaner, and the left/right pattern is printed on so you don't have to guess which pad goes where.
Installation is the part most people worry about, and INHARD addresses it directly: the kit includes a plastic stick, and the brand says no other special tools are needed — roughly five minutes to swap both pads. That's the kind of job you can do at a desk or on a kitchen counter without watching three videos first. The set weighs about 40 grams in total and measures roughly 5.9 x 0.87 x 4.72 inches, so it's a small, flat package that stores easily until you need it.
One point worth being clear about: INHARD states these pads are compatible with the Beats Solo 4 specifically, and asks you to confirm your model before buying. Solo 3, Studio or other Beats models are a different fit. The brand also notes the pads don't change the sound signature — the goal is comfort and a proper seal, not a tuning change. If your current pads are cracked, shedding flakes onto your ears, or have gone flat so the headphones clamp harder than they used to, this is the fix. If your Solo 4s are in good shape, or you own a different headphone model, skip it.
The Navly Headband is a completely different animal: a fabric sleep headband with Bluetooth audio built in. The headline number is battery life — a 2-hour charge delivers up to 12 hours of continuous playback, which Navly frames as enough to cover a full night of white noise, sleep stories or podcasts, or a long red-eye flight without hunting for an outlet. That overnight framing is the whole point of the product.
The design choices back it up. The control panel is only 0.3 inches thin, which matters if you sleep on your side and don't want a hard plastic lump pressing into your temple. The band itself is breathable fabric and machine washable — a genuinely practical detail for something worn against your skin nightly. Weight is listed at 0.11 kg, and it folds flat to slide into a purse, backpack or gym bag. Navly positions it for power naps at work, bus rides and camping as much as for bed.
On audio, the approach is deliberately simple. There's no active noise cancellation. Instead, the soft fabric and snug fit passively muffle a snoring partner, traffic or office chatter — gentler on the ears and without draining the battery on electronics. Standard Bluetooth handles pairing with phones, tablets and laptops, and a hidden microphone lets you take calls or trigger a voice assistant without taking the band off. In the box you get the headband, a USB-C charging cable and a manual. Navly backs it with a two-year warranty.
Who should skip it: anyone expecting real noise cancellation, audiophile-grade sound, or a replacement part for existing headphones. This is a comfort-first, sleep-first device for adults and teenagers who want audio without earbuds.

If I had to pick one, I'd pick based on what's broken in your life. If your Beats Solo 4 pads are the problem, I'd buy the INHARD Replacement Beats Solo4 — it's a focused, well-specified kit with the right materials and a genuinely easy install, and it's the only way either product solves that problem. But if you're shopping for something to wear, not to repair, I'd buy the Navly Headband: the 12-hour battery, thin control panel, washable fabric and two-year warranty make it the more versatile everyday device for sleepers and travelers. In my opinion, most people searching this comparison want the sleep headband.
No — INHARD lists compatibility with the Beats Solo 4 on-ear headphones only, and asks buyers to confirm their model first. If you own Solo 3 or another Beats model, these pads aren't the right fit.
No. Navly uses passive noise reduction instead: the soft fabric and snug fit help muffle snoring, traffic and chatter, but there's no active ANC circuitry. That keeps it light and avoids extra battery drain.
That's what it's designed for. The control panel is only 0.3 inches thin, and the band is breathable fabric, so there's less bulk pressing against your head than a typical headband-style headphone.

Hard to say from specs alone. INHARD lists no warranty, while Navly includes a two-year warranty. What's clear is that INHARD is a wear part you replace when the foam and leather degrade, while Navly is a device you recharge night after night.
