If you want reference-grade, over-ear studio monitoring with a closed-back design and a wide frequency range, choose Amazon Renewed Beyerdynamic DT 770; if you need compact in-ear monitors with detachable cables, a full accessory kit and a secure stage-ready fit, choose BASN Bmaster 2Pin. These two solve completely different problems, and picking the wrong one is the main reason buyers end up disappointed.
• Amazon Renewed Beyerdynamic DT 770 — biggest strength: closed-back, over-ear studio monitoring with a serious 5 Hz–35,000 Hz frequency range and famously hard-wearing German build quality.
• Amazon Renewed Beyerdynamic DT 770 — biggest trade-off: it's a renewed unit with a 90-day limited warranty, it's wired with no controls or microphone, and it weighs 12.2 ounces on your head.
• BASN Bmaster 2Pin — biggest strength: triple-driver in-ear monitors with detachable 2-pin cables, a huge accessory bundle and sound isolation that suits loud stages.
• BASN Bmaster 2Pin — biggest trade-off: a narrower 20 Hz–20,000 Hz range, a plastic housing, and an in-ear fit that simply isn't the same experience as full-size over-ear cans.
• Buy the Amazon Renewed Beyerdynamic DT 770 if you mix, track, podcast or listen critically at a desk and want one durable pair of over-ears.
• Buy the BASN Bmaster 2Pin if you perform, monitor on the move, or want a pocketable set with a spare cable in the case.
The DT 770 is a closed over-ear headphone built for professional mixing at home or in a studio, and the spec sheet backs that up. The 80-ohm impedance version sits in a sweet spot: low enough to run from a laptop or interface without drama, high enough that a dedicated headphone amp still rewards you. The frequency range of 5 Hz to 35,000 Hz is genuinely wide, and the dynamic drivers are the classic Beyerdynamic formula — pure, high-resolution, and revealing of whatever you feed them. Velour ear cushions and a circumferral (around-the-ear) shape mean long sessions are plausible rather than painful, and the closed-back enclosure means sound stays in and outside noise stays out.
Who should skip it? Two groups, honestly. First, anyone who wants wireless freedom or an inline mic for calls — there are no controls here at all, and the connection is strictly wired. Second, anyone uncomfortable with renewed gear: this is a pre-owned or refurbished unit that was inspected and tested by Amazon-qualified suppliers to work and look like new, and it carries a 90-day limited warranty rather than a full new-product term. If a long warranty matters more to you than the model itself, think hard. Also skip it if you want portability — 12.2 ounces and a full-size frame is a desk companion, not a commute one.
BASN Bmaster 2Pin: Who It's For
The BASN Bmaster is a triple-driver in-ear monitor — two dynamic drivers plus one balanced armature — tuned for stage use but perfectly usable as everyday earphones. The sound signature is described as balanced and coherent: full low end, clear midrange, and a treble that stays pleasant rather than sharp. Impedance is 34 ohm with 97 dB sensitivity, which means it plays loudly from a phone or a small interface without needing extra amplification.
The real story is the fit and the kit. The ergonomic in-ear shape was based on sampling many ear models, and the earhook on the cable keeps the monitor locked in place during live performance — that's the difference between an IEM and a pair of earbuds that fall out mid-song. Sound isolation is a core feature: it keeps outside noise from interfering and preserves detail even at low listening volume. The detachable gold-plated 2-pin cable uses a limit-slot protection design specifically to stop the pins from breaking, which is the single most common failure point on cheaper IEMs.
And then there's what's in the box: three pairs of memory foam tips, six pairs of silicone tips, an inline remote mic cable, a silver-plated OFC cable, Velcro strips, a 6.3 mm adapter, a cable clip, a cleaning tool and a carrying case. Two cables means you can keep a mic cable for calls and a clean cable for monitoring. The 2-pin connector is wired-only, but the inline remote cable adds touch controls.
Who should skip it? If you want big, open, over-ear imaging for mixing, an IEM won't give you that. And if you dislike things in your ear canal for hours, this isn't the format for you. The housing is plastic, which keeps weight down but feels less tank-like than a metal build.
• Best for studio mixing and critical listening → Amazon Renewed Beyerdynamic DT 770. The 5 Hz–35,000 Hz range and closed over-ear design are built for this.
• Best for stage and live performance → BASN Bmaster 2Pin. The earhook cable, sound isolation and secure fit are designed around it.
• Best for commuting and travel → BASN Bmaster 2Pin. It's small, comes with a carry case, and tucks away in a pocket.
• Best for durability and repairability → Amazon Renewed Beyerdynamic DT 770. Hard-wearing German workmanship and a design meant to last.
• Best accessory package → BASN Bmaster 2Pin. Two cables, nine pairs of tips, adapter, clip, cleaning tool and case.
• Best for calls and casual use → BASN Bmaster 2Pin. The inline remote mic cable and touch controls make it the more flexible everyday pick.
• Best if you dislike in-ear fit → Amazon Renewed Beyerdynamic DT 770. Velour over-ear cushions, no ear-canal insertion.
• Best warranty comfort → BASN Bmaster 2Pin. A one-year manufacturer warranty versus 90 days limited on the renewed DT 770.
In my opinion, the Amazon Renewed Beyerdynamic DT 770 is the pick for anyone whose priority is sound quality and durability at a desk — closed-back monitoring with a 5 Hz–35,000 Hz range and a build that's meant to survive years of use. I'd choose the BASN Bmaster 2Pin instead if you perform, travel, or want a complete kit with two cables and a case in one purchase. The deciding question isn't which is "better" — it's whether you sit down to listen or move around while you play. If price is the tiebreaker, check the current price on Amazon for both before you commit.
It's a pre-owned or refurbished unit that was inspected and tested by Amazon-qualified suppliers to work and look like new. It carries a 90-day limited warranty and is eligible for replacement or refund under the Amazon Renewed Guarantee.
Yes. It uses a standard 3.5 mm jack with a 2-pin detachable cable, and at 34 ohm impedance with 97 dB sensitivity it's easy to drive from everyday devices. A 6.3 mm adapter is included for larger gear.
You can use it for gaming — it's a closed over-ear wired headphone with a 3.5 mm jack. For calls, though, there's no microphone and no inline controls, so the BASN Bmaster 2Pin with its inline remote mic cable is the more practical option.
Both isolate sound, but differently. The DT 770 uses a closed over-ear design to block outside noise; the BASN Bmaster 2Pin uses in-ear sound isolation plus memory foam and silicone tips for a sealed fit that holds detail at low volume.
