• Audio-Technica ATH-E40 — biggest strength: a dual phase push-pull driver design aimed squarely at accuracy and clarity, plus a detachable 1.6 m cable with A2DC connectors for durability.
• Audio-Technica ATH-E40 — biggest trade-off: it's a tool, not a toy. The angular housing and isolation-first design are about focus, not flair, and the plastic shells feel utilitarian next to resin.
• TipsyAuthen M1 — biggest strength: up to -36 dB of passive noise isolation from shells refined across 20,000+ ear profiles, with a bamboo-fiber dynamic driver voiced for warm bass and forward vocals.
• TipsyAuthen M1 — biggest trade-off: a single dynamic driver and a 6-month earbud warranty signal an entry-level position in its own lineup, and there's no 6.3 mm adapter in the box.
• Pick the ATH-E40 if you monitor, mix, or want a replaceable cable you can trust on stage.
• Pick the TipsyAuthen M1 if you commute, game casually, or just want an IEM that looks and sounds alive.
The ATH-E40 is built around one idea: accuracy. Its proprietary dual phase push-pull drivers are described as excelling in monitoring applications, delivering exceptional accuracy and clarity across a 20 Hz–20,000 Hz range. That's monitoring language, and it matters. When you're tracking vocals or balancing a mix, you don't want a headphone that flatters the low end; you want one that tells you the truth so your decisions translate elsewhere. The 39-ohm impedance and dynamic driver keep it easy enough to drive from a phone or interface without drama.
The physical design backs that up. The flexible memory cable loops over your ears for a custom fit and long-wearing comfort, and the specially designed housing provides maximum isolation so you can focus on the music. The cable detaches via A2DC connectors, which is the single most practical feature here — cables are the first thing to fail on any IEM, and being able to swap one instead of replacing the whole set is real longevity. The box includes a carrying case, silicone tips in XS/S/M/L, Comply foam tips in M, and a 6.3 mm plug-on adapter, so it works with both a phone and a studio headphone amp out of the box. There's a 2-year warranty behind it.
Who should buy it: musicians, podcasters, engineers, and anyone who wants a neutral-ish reference in-ear for critical listening or on-stage monitoring. Who should skip it: if you want a thick, bass-heavy, "fun" tuning for the gym or the bus, this isn't voiced for that. And if you want a colorful, jewelry-like shell, the black plastic angular design won't scratch that itch.
The M1 goes the other direction entirely. Its headline feature is a bamboo-fiber diaphragm — a single dynamic driver, deliberately. Tipsy's stated philosophy is "less is more," arguing that one well-executed driver with dual-chamber airflow technology beats a spec-sheet driver count. Whether you buy the philosophy or not, the tuning target is clear: warm, lively sound with punchy, controlled low end and full-bodied lower mids that push vocals forward, with smooth highs meant to stay fatigue-free over long sessions. That's a signature built for pop, R&B, hip-hop, rock, and vocal-centric tracks — not for surgical mixing.
Isolation is the other standout. The ergonomic shells were refined from over 20,000 ear profiles, and Tipsy rates passive isolation up to -36 dB. In practice that's the difference between hearing your music and hearing the train. It's a genuinely useful number for commuting, practice rooms, and focused gaming, and it pairs with a 24-ohm impedance and 106 dB sensitivity, which means it'll get loud off almost anything with a 3.5 mm jack.
The design angle is unusual. Each M1 is hand-crafted from high-density resin with a faceplate inspired by Van Gogh's The Starry Night, and the pattern is described as light-sensitive — it shimmers and shifts as you move. The shell is resin rather than plastic, which typically feels more premium in hand. The cable is detachable with a 0.78 mm 2-pin connection, and the box includes the cable, an eartip, a protective case, and a 3.5–6.35 mm adapter. Note the warranty split: 6 months on the earbud, 3 months on the cable. That's shorter than the ATH-E40's coverage and worth knowing going in.
Who should buy it: beginner audiophiles, commuters, casual FPS players, and anyone who wants an expressive, bass-forward IEM that looks like nothing else on the desk. Who should skip it: anyone who needs a reference-flat monitor, a long warranty, or a cable they can replace with pro-standard connectors.
Side-by-Side: Which Should You Choose?
• Best for critical monitoring and mixing → Audio-Technica ATH-E40. The dual phase push-pull driver design is explicitly aimed at accuracy and clarity.
• Best for bass-forward, warm everyday listening → TipsyAuthen M1. Bamboo-fiber dynamic driver voiced for punchy low end and forward vocals.
• Best for cable longevity and pro connectivity → Audio-Technica ATH-E40. Detachable 1.6 m cable with A2DC connectors and a 2-year warranty.
• Best for easy replacement cables on a budget → TipsyAuthen M1. Detachable 0.78 mm 2-pin is the most common aftermarket standard around.
• Best for studio gear compatibility → Audio-Technica ATH-E40. Ships with a 6.3 mm plug-on adapter, silicone tips in four sizes, and Comply foam tips.
• Best for looks and desk appeal → TipsyAuthen M1. Hand-polished resin shells with a light-sensitive Starry Night faceplate.
• Best for long listening sessions → it depends on your taste, but in my opinion the M1's smooth, fatigue-free highs are tuned for exactly that, while the ATH-E40's memory cable is built for long-wearing comfort.
If I had to buy one, I'd take the Audio-Technica ATH-E40. In my opinion, the detachable A2DC cable, the 2-year warranty, the monitoring-grade tuning, and the complete accessory kit make it the more durable, more versatile purchase for anyone who cares about sound accuracy or plans to keep the same pair for years. I'd recommend the TipsyAuthen M1 instead if your priority is enjoyment over reference: warmer tuning, dramatically better isolation, a resin shell with real character, and a standard 2-pin cable you can swap cheaply. Neither is a bad buy — they simply answer different questions. Check the current price on Amazon before you commit, since that's the one variable that can flip this call.
how to clean in ear headphones
Wipe the silicone or foam tips with a dry cloth and replace them when they harden or tear. Both the ATH-E40 and M1 use detachable cables, so you can unplug the cable and gently clean the nozzle area without stressing the connector. Never submerge the shells or push anything into the driver opening.
how to fit in ear headphones
Loop the cable over the top of your ear first, then insert the shell and rotate slightly until it seals. The ATH-E40 ships with silicone tips in XS/S/M/L plus Comply foam tips in M, and the M1 includes an eartip and was shaped from a large ear-profile dataset — so experiment with tip size until the seal feels snug, because isolation depends on it.
how to open in ear headphones
Neither the ATH-E40 nor the M1 is designed to be opened — both are sealed in-ear monitors with no user-serviceable interior. What you can open is the connection: the ATH-E40's A2DC cable and the M1's 0.78 mm 2-pin cable both detach by pulling the connector straight out, which is how you replace a worn cable.
how to ear headphones
If you mean wearing them correctly, the answer is over-ear routing: the cable goes up and over the back of your ear, then down. This is how both monitors are intended to sit, and it's why the ATH-E40 uses a flexible memory cable and why the M1's ergonomic shell is shaped to lock in place. A correct over-ear fit is what delivers the rated isolation.
