How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a proven noise-cancelling over-ear with LDAC wireless audio and a touch-controlled Extra Bass tuning you can dial in from an app, choose Sony 950N1; if you need marathon battery life, six microphones and a foldable travel-ready design, choose Monster Persona 3rd.
• Sony 950N1 — biggest strength: LDAC support plus digital noise cancelling and an Extra Bass tuning you can adjust through the Sony Headphones Connect app. A wireless-first design with NFC pairing and a 3.5 mm cable for passive listening when the battery is gone.
• Sony 950N1 — biggest trade-off: Battery life tops out at 22 hours per charge, and the cups are plastic — it's a wireless-first headphone, so there's no standard headphone jack.
• Monster Persona 3rd — biggest strength: A claimed 70-hour playtime, six microphones, Bluetooth 5.4, three EQ modes including transparency, and a folding design that packs down small.
• Monster Persona 3rd — biggest trade-off: The spec sheet gives you less detail on the audio chain — no codec information and no app-based EQ, just the three onboard modes.
• Who each pick is for: Sony 950N1 for listeners who want bass-forward sound and codec-aware wireless; Monster Persona 3rd for travellers and commuters who hate charging.
The 950N1 is the headphone for someone who wants to feel the low end. Sony's EXTRA BASS processing lifts the bass frequencies specifically, and there's a button on the housing to switch it on. If your library leans toward hip-hop, electronic, dance or anything built on a heavy kick drum, that tuning is the whole point of the product. The frequency range runs 20 Hz to 20,000 Hz, which is the standard full-range spread, so nothing is cut off at the top — the bass is boosted, not the treble sacrificed.
Wireless is where this thing is most comfortable. Bluetooth 5 handles the connection, NFC lets you tap an Android phone to pair, and LDAC support means compatible sources can stream at a higher bitrate than plain SBC or AAC. There's also a Sony Headphones Connect app that lets you tailor the sound to the track you're playing, which is the kind of flexibility you don't get from a fixed tuning. On top of that, digital noise cancelling adapts to your environment, so it adjusts rather than just clamping down on everything at one fixed level.
Who should skip it? Anyone who wants a folding, packable headphone, or anyone who wants to go weeks between charges. The cups are plastic and the design is fixed rather than foldable, and 22 hours is modest by modern standards. There's also no standard headphone jack listed, so wired listening depends on the supplied cable rather than any 3.5 mm socket of your own. As a renewed unit, it also carries a 90-day limited warranty, which is shorter than a new-product warranty — worth knowing before you commit.
Monster Persona 3rd: Who It's For
The Persona 3rd is built around endurance and travel. Monster rates it at 70 hours of playtime per charge, which is more than three times what the Sony offers. For a frequent flyer, a long-haul trucker or someone who simply never remembers to plug things in, that single number changes the entire ownership experience. You charge it, and then you stop thinking about charging it.
The feature set reads like a modern commuter headphone. Bluetooth 5.4 is a recent version of the wireless standard, so pairing and connection stability should be solid with current phones and laptops. There are six microphones, which is a lot — that usually means better voice pickup on calls plus the ambient sensing needed for noise cancelling and transparency modes. And there are three distinct listening modes: a balanced standard mode for everyday listening, a noise cancelling mode that cuts ambient sound so you can focus, and a transparency mode that pipes the outside world in so you can hear announcements or hold a conversation without pulling the headphones off. That third mode is the one people underestimate — it's what makes a headphone usable in an airport, a train station or a shared office.
Comfort and portability get explicit attention here. The ear cups use plush sponge cushioning, the headband has adjustable length settings, and the whole thing folds into a compact shape for a bag or pocket. If you've ever tried to cram a rigid over-ear into a carry-on, you know why that matters.
Side-by-Side: Which Should You Choose?
• Best for bass-forward music → Sony 950N1. EXTRA BASS is a deliberate low-end lift with a dedicated button, and the app lets you adjust it further.
• Best for long battery life → Monster Persona 3rd. 70 hours versus 22 hours is not a close contest.
• Best for high-bitrate wireless audio → Sony 950N1. LDAC support is the standout here; the Persona 3rd's sheet lists no codec.
• Best for noise flexibility → Monster Persona 3rd. Three modes — standard, noise cancelling and transparency — versus one adapting noise cancelling system on the Sony.
• Best for travel and packing → Monster Persona 3rd. The folding design is purpose-built for a bag; the Sony is a fixed-frame headphone.
• Best for hands-free calling → Monster Persona 3rd. Six microphones is a lot of hardware aimed at voice pickup.
• Best if you want wired fallback → Sony 950N1. The supplied cable enables passive listening when the battery runs down.
• Best for app-based sound control → Sony 950N1. The Headphones Connect app lets you tune per track; the Monster relies on onboard modes only.
If I were buying for myself, I'd pick the Sony 950N1 — but only if bass-heavy music and LDAC wireless are what I actually care about, and I'm fine charging every few days. If I were buying for someone who travels constantly, hates charging and wants to hear airport announcements without removing their headphones, I'd point them to the Monster Persona 3rd instead. The honest summary: Sony wins on sound tuning and wireless codec support, Monster wins on endurance, portability and mode flexibility. Match the headphone to your routine, not to the spec sheet bragging rights.
In my opinion, yes — EXTRA BASS is the Sony's defining feature, with a dedicated button and app adjustment. Monster markets "deep bass" too, but the spec sheet doesn't break down how it's tuned, so Sony's approach is the more explicit one.
Monster lists up to 70 hours of playtime; Sony lists up to 22 hours of continuous wireless playback. That's roughly a three-to-one gap, and it's the single biggest practical difference between them.
No folding design is listed for the Sony — it's a fixed-frame over-ear with plastic enclosures. The Monster Persona 3rd folds into a more compact shape specifically for bags and pockets, which makes it the easier travel companion.
The Monster Persona 3rd. Its transparency mode is designed to let ambient sound in on demand, which is handy in airports and offices. The Sony's system focuses on adaptive noise cancelling rather than a dedicated pass-through mode.
That depends on what you need, so check the current price on Amazon for both and weigh it against the features above — 70 hours and three modes on one side, LDAC and Extra Bass on the other.
