Quick Read

Meze 105 AER

Meze's lightest open-back at a rated 336 g, the 105 AER pairs ABS-PC earcups and a metal frame with a self-adjusting suspension headband and breathable velour pads, and it is built to come apart so worn parts can be replaced. Comfort and drivability are the traits reviewers keep returning to: rated at 42 ohms and 112 dB, it reaches loud, clean levels from a MacBook headphone jack or a small dongle, while dynamics, imaging and clarity firm up when it is given a better source. The tuning reads warm-leaning and forgiving, and the midrange is picked out as the high point: a clean bass-to-mid handoff climbing to a 3 kHz hump, natural timbre on acoustic instruments, and vocals that are intimate and full without shouting. Bass carries a light emphasis weighted toward midbass punch and holds structure rather than bloating, though how much sub-bass rumble is really there is disputed. Treble is the contested region: it is described as smooth and rolled off with a recessed 6 kHz that softens note attack and costs bite, and also as sparkly, crisp and a favorite quality. Staging divides the same way, called wide with good left-to-right spread on one hand and surprisingly narrow in stereo width on the other, while imaging and layering are treated as a strength either way. Against the 109 Pro at twice the money it is warmer, smoother and clearly behind on resolution, extension and sparkle. The single-ended stock cable is the recurring packaging complaint.

Sennheiser HD 620S

The HD 620S is a closed-back headphone built on a 42mm dynamic driver, listed at $349.95, rated 150 ohms and 110 dB/Vrms, and easy enough to drive that reviewers report full volume from a phone, an Apple dongle or a game controller. Three points are settled across the coverage: passive isolation is unusually strong for a sealed passive design, out-of-box clamping force is high and eases with wear, and the bass you actually hear depends heavily on seal. Everything else splits. One camp hears a near-neutral, HD 600 adjacent tuning with clean mids and a wide, natural stage for a closed back. The other measures and hears an asymmetric W-shaped response: strong sub-bass, a trough near 200 Hz, a 400-800 Hz hump that reads as boxy, a lower-treble recess and a mid-treble lift that leaves the highs sounding disconnected. A measurement-led review scored it 6.5 out of 10 with a 2.9 predicted-quality mean and called the price hard to justify, while a measurement forum still placed it on its recommended list. Detail and dynamics divide the same way.

Meze's lightest open-back at a rated 336 g, the 105 AER pairs ABS-PC earcups and a metal frame with a self-adjusting suspension headband and breathable velour pads, and it is built to come apart so worn parts can be replaced. Comfort and drivability are the traits reviewers keep returning to: rated at 42 ohms and 112 dB, it reaches loud, clean levels from a MacBook headphone jack or a small dongle, while dynamics, imaging and clarity firm up when it is given a better source.

Against the 109 Pro at twice the money it is warmer, smoother and clearly behind on resolution, extension and sparkle. The single-ended stock cable is the recurring packaging complaint.

Strengths

  • Comfort for long sessions: 336 g, a self-adjusting suspension headband, light clamp force and breathable, replaceable velour pads.
  • Rated at 42 ohms and 112 dB, it plays loudly and cleanly from a laptop headphone jack or a small dongle with no dedicated amp needed.
  • Midrange is the high point: linear bass-to-mid handoff, natural timbre on acoustic instruments, and intimate, full-bodied vocals.
  • Warm, fatigue-free voicing that stays comfortable over hours and is forgiving with bright or hot recordings.
  • Fully user-serviceable: it disassembles completely and replacement parts are sold, offsetting the plastic earcups.
  • Dynamics, imaging and clarity improve audibly with a better source, so it rewards an upgrade without demanding one.

Weaknesses

  • Treble is smooth and rolled off with a recessed 6 kHz that softens note attack, leaving percussion sparse and the top end short of bite.
  • Stereo width is called surprisingly narrow for an open-back, with extreme left and right images pulled inward.
  • Resolution, bass extension and treble sparkle sit clearly below the Meze 109 Pro, which costs twice as much.
  • One single-ended cable in the box, no 4.4 mm balanced option, and the stock cable itself is a recurring complaint.
  • Male vocals can lose a little clarity, and micro-detail is not something the presentation delivers at this level.
  • Earcups are ABS-PC plastic, giving up the wood and metal of pricier Meze models.

Sennheiser HD 620S

The HD 620S is a closed-back headphone built on a 42mm dynamic driver, listed at $349.95, rated 150 ohms and 110 dB/Vrms, and easy enough to drive that reviewers report full volume from a phone, an Apple dongle or a game controller. Three points are settled across the coverage: passive isolation is unusually strong for a sealed passive design, out-of-box clamping force is high and eases with wear, and the bass you actually hear depends heavily on seal. Everything else splits. One camp hears a near-neutral, HD 600 adjacent tuning with clean mids and a wide, natural stage for a closed back. The other measures and hears an asymmetric W-shaped response: strong sub-bass, a trough near 200 Hz, a 400-800 Hz hump that reads as boxy, a lower-treble recess and a mid-treble lift that leaves the highs sounding disconnected. A measurement-led review scored it 6.5 out of 10 with a 2.9 predicted-quality mean and called the price hard to justify, while a measurement forum still placed it on its recommended list. Detail and dynamics divide the same way.

Strengths

  • Passive isolation and leakage control are class-leading for a sealed passive headphone, good enough to work in a cafe or a shared office
  • Easy to drive at 150 ohms and 110 dB/Vrms, so a phone, a cheap dongle DAC or a console controller reaches listening volume
  • Soundstage and imaging read wide and natural for a closed back, and several reviewers rate the staging above the open HD 600 series
  • Deep synthetic leather pads, memory foam headband padding and steel-reinforced cups earn comfort ratings as high as 9 out of 10
  • No hard treble spike in the 4-6 kHz region, so it avoids the glare that the same reviewers pin on the Beyerdynamic DT 770 family

Weaknesses

  • The response is asymmetric and W-shaped: a trough near 200 Hz plus a 400-800 Hz hump that reads as boxy on some material
  • Bass level shifts with seal, pad creasing and headband position, so two fittings of the same unit can sound different
  • Clamping force is high out of the box and caused mild discomfort even for a reviewer who still recommended the headphone
  • Dynamic punch, transient attack and detail retrieval are called unremarkable or weak for the price by more than one reviewer
