If you want comfortable, wide-range wired monitoring for meetings, choose Sony MDR-M1; if you need a foldable, studio-style wired headphone with a storage case, choose Sony MDR-7506. Neither is a Bluetooth headset, and neither data sheet lists a built-in microphone, so these are better suited to listening than to taking calls without separate audio gear.
Sony MDR-M1 vs Sony MDR-7506 at a Glance
• Sony MDR-M1 strength: Closed over-ear design, stated sound isolation, and a 5 Hz–80 kHz frequency range. Trade-off: Wired, and it does not fold for storage in the listed features.
• Sony MDR-7506 strength: Foldable design with a soft carrying case and closed-ear construction. Trade-off: Its cable is not detachable, and its listed frequency range is 10 Hz–20 kHz.
• For meetings: Choose the MDR-M1 if comfortable listening and replaceable cables matter most; choose the MDR-7506 if compact storage is the priority.
• Neither is a Bluetooth option: Both connect by wire, and neither sheet lists a built-in microphone.
The Sony MDR-M1 is an over-ear, closed-back wired headphone built around a 40 mm dynamic driver. Its stated frequency range is 5 Hz–80 kHz, and its closed acoustic design is intended to provide sound isolation for monitoring. That combination makes it the more compelling pick here for someone who wants to listen closely to voices, recordings, or other audio during a work session.
Comfort and upkeep are notable parts of its design. The soft, thick earpads are intended for longer listening sessions, and the headphone weighs approximately 216 g. It comes with two detachable cables, replaceable earpads, and a screw-in adapter for connecting to either a 3.5 mm or 6.3 mm stereo jack. The detachable connection is a practical advantage if you want a cable that can be replaced rather than one permanently attached.

The Sony MDR-7506 is also a wired, over-ear closed design with 40 mm drivers. Its stated frequency range is 10 Hz–20 kHz, and the closed earcups are intended to reduce external noise. It folds for storage and comes with a soft case, which gives it a clear advantage for someone who regularly packs headphones away between work sessions.
Its main practical compromise is the cable. The MDR-7506 has a long, non-detachable cord ending in a 3.5 mm plug, with a 1/4-inch adapter included. That setup can be useful with compatible audio equipment, but you cannot simply swap out the cable if it is damaged or inconvenient. Its foldable design is a stronger reason to choose it than expecting a wireless meeting experience.
For meetings, the MDR-7506 fits someone who needs wired headphones that can be stored in a case when not in use. It is not the right choice if you want Bluetooth, a listed microphone, or a detachable cable. The product details do not identify it as a sports earbud either: it is a foldable over-ear headphone, not a pair of earbuds.
• Best for a wide stated frequency range → Sony MDR-M1. Its listed range is 5 Hz–80 kHz, compared with 10 Hz–20 kHz for the MDR-7506.
• Best for replaceable cables → Sony MDR-M1. It has two detachable cables and a screw-system connection at the headphone.
• Best for folding into a case → Sony MDR-7506. Its foldable design and included soft case suit storage and travel.
• Best for stated earpad replacement → Sony MDR-M1. Replaceable earpads are part of its listed design.
• Best for a wired 3.5 mm or 6.3 mm connection → Sony MDR-M1. Its screw-in adapter supports both jack sizes.
• Best if you want a long, fixed cable and included 1/4-inch adapter → Sony MDR-7506. Its cable is not detachable, so that trade-off is worth considering.
• Best for Bluetooth meetings → Neither. Both are wired, and neither product’s listed details include a built-in microphone.
• Best for a compact over-ear option → Sony MDR-7506. Folding is its clearest convenience advantage over the MDR-M1.
The search for the “best bluetooth headphones for meetings” points toward a different kind of product than either of these. Both Sonys are wired, so they are a better fit for a desk setup with a compatible audio connection than for someone who wants to move around untethered. A “foldable sports earbuds for meetings” search also describes a different form factor: the MDR-7506 folds, but it is an over-ear headphone, not an earbud.
My Verdict
I’d choose the Sony MDR-M1 for meetings when I want wired, over-ear listening, stated sound isolation, and a detachable cable. Its replaceable earpads and broad listed frequency range make it the more flexible option for longer listening sessions and monitoring. That recommendation assumes a separate microphone or meeting device; neither headphone is listed with a built-in mic. If folding and a case matter more, I’d pick the MDR-7506 instead.
No. Both are listed as wired headphones. Neither product’s details list Bluetooth connectivity, so neither is a match if wireless use is essential.
For wired listening during meetings, I’d lean toward the MDR-M1 for its thick earpads, detachable cables, and stated sound isolation. The MDR-7506 is a better fit if folding and a soft storage case matter more. Neither has a built-in microphone listed.
The MDR-7506’s cable is not detachable, according to its listed details. The MDR-M1 has two detachable cables and a screw-system connection, so it has the clear advantage if cable replacement matters to you.
The Sony MDR-7506 folds and comes with a soft case. The MDR-M1’s listed features include detachable cables and replaceable earpads, but do not identify it as foldable.
