If you want a budget-friendly way to refresh an existing pair of Beats Solo2 or Solo3 on-ear headphones with plusher memory foam and a better seal, choose SoloWIT Earpads; if you need a complete closed-back studio headphone for mixing, monitoring and DJ work, choose iCON Pro Audio HP-310. One is a replacement pad kit for headphones you already own. The other is the headphone itself. That distinction matters more than anything else here, especially if you're shopping for DJ use, where fit, isolation and a locked-in low end matter as much as raw detail.
• SoloWIT Earpads — biggest strength: Extra thick, slow-rebound memory foam that conforms to your ears for a personalized fit, with a triangle opener included for fast installation.
• SoloWIT Earpads — biggest trade-off: It is not a headphone. It only fits Beats Solo2 and Solo3 Wireless (Model B0534 and Model A1796) and will not fit Studio Over-Ear, Solo HD or Solo 4 models.
• iCON Pro Audio HP-310 — biggest strength: A complete wired closed-back studio headphone with 50mm dynamic drivers, a 10Hz–30kHz range and 32Ω low impedance that runs straight from a phone, tablet or laptop without an amp.
• iCON Pro Audio HP-310 — biggest trade-off: It's a wired-only, open-ear-placed over-ear design, so it isn't a grab-and-go wireless pair and it isn't a fix for headphones you already own.
• Who SoloWIT Earpads is for: Beats Solo2/Solo3 owners who want better bass, comfort and seal without buying new headphones.
• Who iCON Pro Audio HP-310 is for: Producers, engineers, gamers and DJs who need one closed-back headphone for mixing, tracking and monitoring.
Think of this as a tune-up part, not a product you build a rig around. SoloWIT takes the two things that usually wear out first on an on-ear headphone — the pads and the seal — and rebuilds them with extra thick, slow-rebound memory foam. That foam conforms to the shape of your ear over time, which is exactly what you want on an on-ear design: a better seal means more of the low end reaches your ear instead of leaking out, and the brand explicitly frames the result as excellent bass and extreme comfort. The enclosure material is faux leather in white, and the kit ships with a triangle opener so you can pry the old pads off and seat the new ones without hunting for tools.
The compatibility list is the whole ballgame, so read it carefully. These pads fit Beats Solo2 and Solo3 Wireless, including Model B0534 and Model A1796. They do not fit Beats Studio Over-Ear, Solo HD or Solo 4. If you own any of those, this is the wrong purchase, full stop. The single unit count also means you're buying one set, so if you're refreshing two pairs, plan accordingly.
iCON Pro Audio HP-310: Who It's For
The HP-310 is a different category of purchase entirely — a purpose-built closed-back studio headphone for precision monitoring. The headline spec is a custom-tuned 50mm dynamic driver with a 10Hz–30kHz frequency response, which is a genuinely wide range covering everything from sub-bass you feel more than hear up to treble well past what human hearing resolves. The brand pairs that with a lightweight voice coil and dual audio damping to balance the spectrum and pull out fine detail, and describes the tuning as rich in bass with clear vocals and true-to-life reproduction.
The practical win is the 32Ω low-impedance, high-sensitivity design. You do not need an external amp or a dedicated interface to drive these — a smartphone, tablet or laptop will do it. For anyone who mixes on the move or works from a laptop without a headphone amp on the desk, that removes a real barrier. Worth flagging one inconsistency in the listing data: the marketing copy cites 40mm neodymium drivers while the audio specs list 50mm dynamic drivers and a 140-ohm impedance figure, so I'd treat the 32Ω claim and the driver size as the specs to verify before you commit if either is a dealbreaker.
Isolation is the other core feature. The closed-back design plus a gradient cavity is engineered to seal out ambient noise and keep sound from leaking, which is what makes it suitable for critical vocal tracking, mixing and gaming. The brand also calls out adaptive noise cancellation as a noise-control feature. Physically, you get a self-adjusting headband, upgraded memory foam cushions and a lightweight build aimed at reducing fatigue over long sessions — the kind of thing that matters when you're three hours into a mix. In the box: a 3-meter straight cable with a gold-plated 3.5mm plug, a 6.35mm screw-on adapter, and a quickstart guide. Wired only, over-ear placement, adult sizing, three-year warranty.
Who should buy it: engineers and producers who need one honest closed-back reference pair, gamers who want isolation plus a wide stage, and DJs who want a wired, amp-free headphone with real low-end weight. Who should skip it: anyone who wants wireless, and anyone who only needs replacement pads.
• Best for repairing what you own → SoloWIT Earpads. If your Solo2 or Solo3 pads are worn, this restores comfort and seal.
• Best for a complete headphone → iCON Pro Audio HP-310. It's a finished product, not a part.
• Best for amp-free setup → iCON Pro Audio HP-310. The 32Ω low-impedance design runs straight off a phone, tablet or laptop.
• Best for isolation while tracking or gaming → iCON Pro Audio HP-310. Closed-back sealing is the entire point of the design.
• Best for long-session comfort on either path → both, for different reasons. SoloWIT uses slow-rebound memory foam in the pads; the HP-310 uses a self-adjusting headband plus memory foam cushions.
• Best for DJ use → iCON Pro Audio HP-310. A wired connection, a 3-meter cable and strong low-end presence suit cueing and monitoring far better than a pad swap.
• Best if you don't own Solo2 or Solo3 → iCON Pro Audio HP-310. The SoloWIT pads simply won't fit anything else.
• Best if you want the lowest-commitment fix → SoloWIT Earpads. It's a small part that extends the life of headphones you already chose.
If you're buying for DJ work and you need an actual headphone rather than a repair, I'd buy the iCON Pro Audio HP-310. In my opinion it's the more complete, more versatile purchase: a closed-back studio design with 50mm drivers, a wide 10Hz–30kHz range, 32Ω low impedance that needs no amp, a 3-meter cable and a 6.35mm adapter in the box. That combination covers mixing, monitoring, tracking, gaming and DJ cueing from one wired pair. The SoloWIT Earpads are genuinely good at one narrow job — reviving Beats Solo2 or Solo3 with thicker memory foam and a better seal — but only buy them if that's the exact headphone you own. Check the current price on Amazon for whichever one matches your setup before you decide.
are studio headphones worth it
For anyone mixing, tracking or monitoring, yes — a closed-back wired design like the HP-310 gives you isolation, a wide 10Hz–30kHz range and honest detail at a level typical listening gear doesn't target. If you only stream music casually, the benefit is smaller.
what headphones do professional studios use
Studios generally rely on closed-back, wired headphones for tracking and monitoring because the sealed design limits bleed into microphones. The HP-310 fits that mold with its closed-back cavity, 50mm dynamic drivers and 3-meter cable with a 6.35mm adapter.
how do over ear headphones work
Over-ear headphones place the driver around the ear rather than on it, and a closed-back enclosure seals the space so ambient noise is blocked and sound stays in. The HP-310 adds a gradient cavity and adaptive noise cancellation to strengthen that effect.
how to wear over ear headphones
Set the headband so the cushions sit fully around your ears without pressing on them, then let a self-adjusting band like the HP-310's settle the fit. A proper seal is what preserves bass and isolation — the same reason SoloWIT's memory foam pads are designed to conform to your ears.
