How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired in-ear with a hybrid dual-driver setup and a built-in mic for calls, choose Phiaton MS 300; if you need replacement luxury earpads that upgrade the comfort and isolation of SMB-02 or SMB-02G headphones you already own, choose PHONON SMB-02/02G.
• Phiaton MS 300 — biggest strength: a hybrid driver design that pairs a balanced armature with a dynamic driver, plus LPF technology that lets each driver focus on the frequencies it handles best.
• Phiaton MS 300 — biggest trade-off: it's a wired in-ear with a 3.5 mm jack, so it's tethered to your device and won't suit anyone who wants a fully wireless setup.
• PHONON SMB-02/02G — biggest strength: protein leather on the surface and polyurethane leather inside, built to add sound insulation and cut bass reverberation.
• PHONON SMB-02/02G — biggest trade-off: these are replacement earpads only — the SMB-02 headphones themselves are not included, so they're useless unless you already own a compatible pair.
• Who each pick is for: the Phiaton MS 300 suits someone who wants a complete, ready-to-use earphone for music and calls; the PHONON SMB-02/02G suits an existing SMB-02 or SMB-02G owner refreshing worn pads.
The Phiaton MS 300 is a complete earphone, not an accessory. Its whole pitch is the driver arrangement: a balanced armature driver handles the mid and high frequencies, while a 10 mm dynamic driver covers the low end. Phiaton adds what it calls Dynamic Driver LPF technology — a low frequency pass filter that strips high frequency content out of the dynamic driver's signal so it can concentrate purely on bass precision. The result, as the design intends it, is a hybrid where each driver does the job it's better at instead of one driver trying to cover everything.
The practical extras matter just as much. There's an in-line remote with a button for controlling music and answering calls, so it works as a headset and not just a listening tool. The cable is oval-shaped and textured, a design choice meant to reduce tangling and cut down on cable touch noise — the thumping you hear when a cable brushes against your clothes. The conductors are oxygen-free copper at 99.99% purity, and the jack is gold plated. In the box you get a carrying case and four sizes of eartips, which covers most ear sizes out of the gate.
Who should skip it: anyone who wants wireless listening as the primary mode. The data sheet lists Bluetooth under connectivity technology, but the core product here is a wired 3.5 mm earphone, and the design is built around that cable. If you want zero wires, this isn't the shape of product you're shopping for. Also skip it if you dislike in-ear fit — this is an in-ear design with a rounded tip, not an over-ear.
PHONON SMB-02/02G: Who It's For
This is a very different kind of purchase. The PHONON SMB-02/02G listing is for one pair of replacement earpads — left and right — made for the SMB-02 and SMB-02G headphones. The headphones are not included. That single fact should decide whether you keep reading: if you don't own a compatible PHONON headphone, these pads have nothing to attach to.
For the person who does own one, the materials are the story. The outer surface is high quality protein leather, chosen for comfort against the skin. The interior is polyurethane leather, and its job is to reduce bass reverberation — the trapped, boomy quality that builds up when pads reflect low frequencies back at your ear. PHONON also says the large gussets maintain a certain amount of side pressure even with that low-reverberation fit, which matters because pads that go too loose lose their seal and with it the bass and isolation.
Speaking of isolation: PHONON explicitly frames these pads as adding sound insulation and blocking external sound better, and as improving the monitoring environment for studio work and at-home listening. That's the honest use case. Worn pads flatten and stop sealing; fresh pads restore the seal, and the seal is what gives you both the isolation and the low-end response.
Who should buy it: an SMB-02 or SMB-02G owner whose current pads are compressed, cracking or no longer sealing properly, and who wants to restore the comfort and isolation the headphone was designed around.
Who should skip it: everyone else. If you're shopping for headphones rather than parts, this isn't a headphone.
Side-by-Side: Which Should You Choose?
• Best for a complete, ready-to-use product → Phiaton MS 300. It's a finished earphone with eartips, case, cable and remote in the box.
• Best for calls and remote control → Phiaton MS 300. The in-line button remote handles music and phone calls.
• Best for sound isolation from physical fit → PHONON SMB-02/02G. Protein leather pads with a sealing fit are the mechanism here.
• Best for detailed treble and textured mid-high detail → Phiaton MS 300. The balanced armature driver is the reason.
• Best for controlling bass reverberation → PHONON SMB-02/02G. The polyurethane interior is specified to reduce it.
• Best for studio monitoring and home listening comfort → PHONON SMB-02/02G. That's the exact scenario PHONON describes.
• Best for tangle resistance on the go → Phiaton MS 300. The oval textured cable is designed to uncoil cleanly and cut touch noise.
In my opinion, these two products barely compete — they solve different problems, so the right answer depends entirely on what you already own. If you're buying a headphone today, I'd choose the Phiaton MS 300: it's a complete hybrid-driver earphone with a mic, a remote, a case and four eartip sizes, and it's designed to be used the moment you open it. If you already own PHONON SMB-02 or SMB-02G headphones and the pads are worn, I'd choose the PHONON SMB-02/02G earpads, because no new earphone will fix a broken seal on the headphone you already love. Check the current price on Amazon for whichever one matches your situation.
what are high end headphones
There's no single definition, but the phrase generally describes headphones built around better materials and more specialized engineering rather than basic function. The Phiaton MS 300 fits that idea through its hybrid balanced armature plus dynamic driver layout and oxygen-free copper cabling; the PHONON SMB-02/02G fits it through protein and polyurethane leather construction aimed at isolation and controlled bass.
what are the best luxury headphones
"Best" is personal, so I'd reframe it as which luxury approach suits you. In my opinion, if you want a self-contained earphone with a hybrid driver and an in-line mic, the Phiaton MS 300 is the stronger pick. If you want to upgrade the feel and isolation of headphones you already own, the PHONON SMB-02/02G earpads are the better fit.
what are considered high end headphones
Comfort materials, isolation and driver specialization are the usual markers. The Phiaton MS 300 shows this in its dual-driver design and LPF bass filtering; the PHONON SMB-02/02G shows it in protein leather surfaces, a polyurethane interior that reduces bass reverberation, and gussets that preserve side pressure for a proper seal.
what are some high end headphones
Among the two here, the Phiaton MS 300 is the one that is an actual headphone — a wired in-ear with a balanced armature and 10 mm dynamic driver, a remote, and a carrying case. The PHONON SMB-02/02G is a pair of replacement luxury earpads for the SMB-02 and SMB-02G, so it complements a high-end headphone rather than being one.
