• Amazon Renewed Beats Studio Buds — biggest strength: A fully wireless, noise-cancelling design rated for up to 36 hours of total listening time with the charging case, plus IPX4 sweat and water resistance for workouts and commutes.
• Amazon Renewed Beats Studio Buds — biggest trade-off: It's a renewed (refurbished) unit covered by a 90-day limited warranty, and the in-ear, plastic build won't match the premium feel of a new pair.
• OneOdio Monitor 80 — biggest strength: A 250-ohm open-back design with 40 mm drivers, a 10 Hz–40 kHz range, and velour pads built for long studio sessions.
• OneOdio Monitor 80 — biggest trade-off: It's wired only and its 250-ohm impedance means it must be driven by an amp — a phone or laptop alone won't get the most out of it.
• Pick the Beats if you want portable, wireless, noise-cancelling everyday listening.
• Pick the OneOdio if you're mixing, mastering, or editing at a desk and already have (or plan to buy) a headphone amp.
The Beats Studio Buds + is built around convenience and everyday listening. Beats' custom acoustic platform drives the sound, and you get two distinct modes: personalized Active Noise Cancelling to cut down background noise, and Transparency mode when you need to hear what's around you. That pairing is genuinely useful — ANC for the train or a noisy office, Transparency for crossing a street or ordering coffee.
Battery is the headline number here. Beats rates the earbuds at up to 9 hours on a single charge and up to 36 hours total with the pocketable charging case (27 extra hours). Four pairs of silicone tips are included so you can find a seal that fits your ears, and that seal matters — it's what makes both the noise cancelling and the bass work properly. One-touch pairing works across both Apple and Android, and the beamforming microphones (described as three times larger) are aimed at clearer calls.
This is the pick for someone who wants one set of earbuds for the gym, the commute, and the desk. IPX4 resistance covers sweat and splashes, so a run or light rain won't sideline them. Skip it if you want wired, reference-grade accuracy for studio work, or if you'd rather have the full manufacturer warranty — this is a renewed unit with a 90-day limited warranty, and that shorter coverage is the real cost of going renewed.
The Monitor 80 is a different animal entirely, and it's meant to be. This is an open-back, over-ear studio headphone with 40 mm drivers, aluminum honeycomb housing, and high-precision etched diaphragms. The open-back design lets air move freely in and out of the cups, which reduces internal pressure and resonance — that's the physics behind the "natural, open, realistic" sound OneOdio describes. If you've only used closed-back headphones, the first thing you'll notice is how much wider and less boxed-in everything sounds.
The spec that changes everything is impedance: 250 ohms. OneOdio is explicit that these must be driven by an amp when used with a phone, computer, or similar device. Plug them straight into a laptop headphone jack and you'll get sound, but you won't get the stable, full-bodied performance the design is capable of. Pair them with a proper headphone amplifier and the 10 Hz–40 kHz range, 100 dB sensitivity, and low distortion start to make sense.
Comfort is clearly a design priority. The velour ear pads are soft and breathable, the headband adjusts, and the hinge is rated to survive 100,000+ rotations. You get two cables: a 3 m straight 3.5 mm cable and a coiled 1.5–3.5 m cable with a 6.35 mm adapter, so you can go straight into an interface or a mixer without hunting for a separate adapter. Skip it if you want wireless, noise cancelling, or something to wear on a run — it's wired, it's open-back, and it leaks sound both ways by design.
Side-by-Side: Which Should You Choose?
• Best for battery life → Amazon Renewed Beats Studio Buds. Up to 9 hours per charge and up to 36 hours total with the case; the Monitor 80 has no battery at all.
• Best for noise cancelling → Amazon Renewed Beats Studio Buds. It's the only one of the two with Active Noise Cancellation and a Transparency mode.
• Best for commuting, workouts, and travel → Amazon Renewed Beats Studio Buds. Wireless, IPX4-rated, and pocketable.
• Best for long desk sessions → OneOdio Monitor 80. Velour pads, an adjustable headband, and a design meant for hours of monitoring without pressure.
• Best for call quality → Amazon Renewed Beats Studio Buds. It's the only one with built-in beamforming microphones.
• Best for durability you can inspect → OneOdio Monitor 80. Aluminum housing and a hinge tested past 100,000 rotations, backed by a 1-year warranty versus 90 days on the renewed Beats.
• Best if you don't own an amp → Amazon Renewed Beats Studio Buds. The Monitor 80's 250-ohm load really wants dedicated amplification to shine.
In my opinion, the right answer depends entirely on where you'll use them, not which is "better." If you want one pair for music, calls, the gym, and the train, I'd buy the Amazon Renewed Beats Studio Buds — wireless freedom, ANC, and 36 hours of total battery are hard to argue with, and the trade-off is simply the renewed unit's 90-day warranty. If your listening happens at a desk with an amp and you care about an honest, uncolored mix, I'd buy the OneOdio Monitor 80 instead. Different tools, different jobs.
It depends on how much you value the warranty. The renewed unit carries a 90-day limited warranty rather than a full manufacturer term, so you're trading some long-term coverage for the renewed route. Check the current price on Amazon and weigh that against your comfort with renewed electronics.
Yes, practically speaking. Its 250-ohm nominal impedance means phones, laptops, and similar devices won't drive it to its full potential — OneOdio states it must be used with an amp. A dedicated headphone amplifier is the intended pairing.
The Beats. It offers Active Noise Cancellation plus four sizes of silicone tips to create a sealing fit that keeps noise out. The Monitor 80 is open-back by design, so it deliberately lets sound in and out rather than blocking it.
It's wired and has no microphones, so it's not built for calls or voice chat on its own. For gaming at a desk it can work well if your setup has an amp and a separate mic, but it isn't a grab-and-go headset.
