If you want a premium on-ear headphone with spatial audio, lossless wired playback and a 50-hour battery, choose Beats Solo 4; if you need tiny, ultra-light true wireless earbuds with a charging case that shows you exactly how much power is left, choose Nequga Ear Buds.
These two products sit in completely different corners of the audio world. One is a full-size on-ear headphone from a well-known brand with a wired lossless option. The other is a budget-friendly pair of in-ear buds built around convenience, a digital power display and a pocketable case. Neither is "better" in a vacuum — the right pick comes down to how you actually listen.
• Beats Solo 4 — biggest strength: Custom acoustic architecture, Personalized Spatial Audio with dynamic head tracking, and high-resolution lossless audio over USB-C or a 3.5 mm cable.
• Beats Solo 4 — biggest trade-off: It's an on-ear headphone, roughly 1.1–1.12 pounds and 8.19 x 5.04 x 3.69 inches, so it's a bag item, not a pocket item, and it's priced well above budget earbuds.
• Nequga Ear Buds — biggest strength: A 500mAh charging case with an LED display showing exact remaining power from 0–100%, delivering up to 50 hours of total playtime by alternating between buds.
• Nequga Ear Buds — biggest trade-off: Passive noise cancellation only, and no wired lossless path — this is a wireless-only, convenience-first design.
• Who Beats Solo 4 is for: listeners who want immersive spatial audio, long single-charge sessions and a wired hi-res option at home or at a desk.
• Who Nequga Ear Buds is for: commuters, joggers and travelers who want featherweight buds (3.9g each) plus a case small enough for a front pocket.
The Solo 4 is built around sound quality and long-haul comfort. Beats describes a custom acoustic architecture with updated drivers, and the headline feature is Personalized Spatial Audio with dynamic head tracking — the kind of thing that makes a movie or an album feel like it's moving around you rather than sitting flat in front of you. If you've never used head-tracked spatial audio, the practical effect is that turning your head shifts the soundstage, which is genuinely useful for watching films on a laptop or tablet.
Comfort is clearly a design priority. The headband uses a flex-grip design, the ear cups are ergonomically angled and adjustable for a stable fit, and the UltraPlush cushions are pitched at both comfort and durability. At around 1.1 pounds it's light for an on-ear headphone, though "ultralight" here is relative — you'll feel it on your head, just not in a distracting way. Battery life is the standout number: up to 50 hours, plus Fast Fuel, where a 10-minute charge gives up to 5 hours of playback. That combination means you can top up before a flight and not think about charging again for days.
There's also a wired escape hatch that most true wireless buds simply don't offer: high-resolution lossless audio over USB-C or a 3.5 mm cable. That matters if you have a lossless source — a laptop, a DAC, a digital audio player — and you want to bypass Bluetooth entirely. Apple and Android compatibility is stated as well, so it isn't locked to one ecosystem.
Who should buy it? Someone who listens for long stretches, cares about spatial audio and lossless playback, and doesn't mind carrying a headphone rather than pocketing buds. Who should skip it? If your priority is something that disappears into a jeans pocket, survives gym sweat without a second thought, or costs as little as possible, the Solo 4 is the wrong shape and the wrong price tier. Check the current price on Amazon before deciding, since headphone pricing moves around more than most categories.
The Nequga Ear Buds are a different philosophy entirely: maximum portability, minimum fuss. Each bud weighs just 3.9g, and the 45° ergonomic angle is designed to ease pressure during long wear. They ship with S/M/L silicone tips so you can find a snug, secure fit regardless of ear size — a small detail that matters a lot, because in-ear fit is what determines whether buds stay put during a jog or fall out at the worst moment.
The charging case is the real story. It's rated at 500mAh and delivers up to 50 hours of total playtime by alternating between the two buds, and there's a built-in LED display that shows exact remaining power from 0–100%. That's a genuinely practical touch: no guessing whether the case is half full or nearly dead before you leave the house. The case itself measures just 1.92 x 2.59 inches, so it slips into a front pocket, a small clutch or a backpack side pouch without a fight.
Who should buy it? Commuters, travelers and casual exercisers who want lightweight buds, a case with a visible battery readout, and a fit they can fine-tune with three tip sizes. Who should skip it? Anyone who wants spatial audio, a wired lossless option, or a design that trades portability for acoustic hardware. If you mostly listen critically at a desk, the in-ear, passive-cancellation format will feel like a compromise.
Side-by-Side: Which Should You Choose?
• Best for spatial audio and immersive movie watching → Beats Solo 4 (Personalized Spatial Audio with dynamic head tracking).
• Best for battery convenience and knowing your exact charge → Nequga Ear Buds (LED display showing 0–100% remaining power in the case).
• Best for wired, high-resolution lossless listening → Beats Solo 4 (USB-C or 3.5 mm cable).
• Best for pocketability → Nequga Ear Buds (1.92 x 2.59-inch case that fits a front pocket).
• Best for long single-charge sessions on one device → Beats Solo 4 (up to 50 hours, plus 5 hours from a 10-minute Fast Fuel charge).
• Best for all-day light wear → Nequga Ear Buds (3.9g per bud with a 45° angled fit and three tip sizes).
• Best for workouts and light rain → Nequga Ear Buds (IPX5 waterproofing).
• Best for adjustable, stable over-ear fit → Beats Solo 4 (flex-grip headband with angled, adjustable ear cups).
If I had to pick one for myself, I'd buy the Beats Solo 4. In my opinion, the combination of Personalized Spatial Audio, a genuine lossless wired path over USB-C or 3.5 mm, and up to 50 hours of battery covers more of the ways I actually listen — at a desk, on a plane, and plugged into a laptop for films. The Nequga Ear Buds are the smarter choice if portability and a visible battery readout matter more to you than acoustic hardware, but they're a convenience-first product by design. Weigh what you'll do most, then check the current price on Amazon for both before you commit.
FAQ
They use passive noise cancellation, not active. That means the seal from the S/M/L silicone tips blocks some outside sound, but there's no electronic noise-cancelling system listed. If you want heavy noise blocking on a plane, that's a point in favor of an over-ear design instead.
Both are rated at up to 50 hours, but the way you get there differs. The Solo 4 lists up to 50 hours of playback plus a 10-minute Fast Fuel charge for up to 5 hours. The Nequga case is 500mAh and reaches 50 hours total by alternating between the two buds.
Yes. The Solo 4 is listed as Apple and Android compatible, and the wired lossless option over USB-C or a 3.5 mm cable works independently of Bluetooth. The Nequga buds connect wirelessly via Bluetooth 5.3 with a stated range of up to 15 meters.
