For musicians, OneOdio is my pick for studio headphones for musicians: the A70 pairs wired studio connections with Bluetooth listening. Tascam is the simpler wired alternative, with a foldable design and a 1/4-inch adapter.
• OneOdio A70 — best for switching between studio gear and wireless listening; pick this if you want Bluetooth, up to 72 hours of wireless playback, and 3.5 mm and 6.35 mm connections.
• OneOdio A70 — best for shared listening and easier packing; pick this if its foldable design, included cables, and ability to pass audio to additional headphones suit your setup.
• Tascam TH-02 — best for straightforward wired monitoring; pick this if you want a closed-back design, a foldable frame, and a snap-on 1/4-inch adapter.
• SAMSON SR850 — best for a more open listening presentation; pick this if you want semi-open headphones with 50 mm drivers and a self-adjusting headband.
The A70 is an over-ear headphone designed to cover both studio and everyday listening. Its 40 mm dynamic drivers, Bluetooth connectivity, and 3.5 mm and 6.35 mm jack options make it the most flexible choice in this group. For musicians moving between a computer, an instrument amp, and a phone, that mix can reduce the need to keep separate headphones for each task.
The wired connections are the clearest reason to consider it for a working setup. A 6.35 mm plug is useful with equipment that has a larger headphone output, while 3.5 mm suits many everyday audio connections. Bluetooth adds a wireless option away from the studio. The stated wireless playback time is up to 72 hours, though that figure describes wireless use rather than wired sessions.
The A70 can also share audio through its dual-jack arrangement: connect it to a source, then connect another set of headphones. That could help when a musician and collaborator need to listen to the same passage without relying on a separate splitter. The 32-ohm impedance is another useful spec when considering common devices, though it does not by itself guarantee identical loudness from every source.
The trade-off is that Bluetooth and multiple connection options make this a more feature-heavy choice than a simple wired monitor. Its stated frequency range is 20 Hz to 20 kHz; those figures alone cannot establish how neutral or revealing it sounds in practice.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
This listing is also for the OneOdio A70, with the same core combination of Bluetooth, 40 mm dynamic drivers, and 3.5 mm and 6.35 mm connections. Its listed details emphasize a foldable headband and rotatable earcups, making it the more travel-conscious version to consider if the ability to pack headphones neatly matters in your routine.
For musicians who split time between a home workspace and rehearsals, folding construction can make storage simpler. The included pouch and cables add practical options, and the same audio-sharing feature can pass a source to additional wired headphones. Up to 72 hours of wireless playback is specified, giving it flexibility for listening away from a wired setup.
There is some overlap with the other A70 listing, so I would focus on the differences that matter to you rather than treating it as an entirely different headphone. This version specifically describes memory cotton and skin-friendly protein leather in the ear pads, plus foldability. The 32-ohm impedance and 20 Hz–20 kHz frequency range match the first listing’s core audio figures.
The trade-off remains the same: the A70 is not a dedicated noise-cancelling model, and wireless convenience does not tell you whether its sound is suitable for precise tonal decisions. If you want the simplest possible studio connection, the Tascam is a more straightforward wired option. If packability and wireless listening both matter, this A70 listing makes a stronger case.
The TH-02 is a wired, closed-back over-ear headphone with a foldable design. It is the most direct choice here for someone who wants to connect to a recording setup and get on with monitoring, without adding Bluetooth or wireless battery use to the decision. Its 50 mm dynamic drivers and included snap-on adapter provide a clear studio-oriented starting point.
The adapter changes the plug from 3.5 mm to 6.3 mm, making it easier to use with equipment that has a larger headphone socket. The stated frequency range is 18 Hz to 22 kHz, and the impedance is 32 ohms. Those specifications help describe its compatibility and stated range, but they cannot tell you by themselves how mixes will translate to other speakers or headphones.
Its closed-back design is a practical distinction. Musicians recording near a microphone may prefer a closed-back style when they want a more enclosed listening arrangement than a semi-open headphone provides. The foldable construction is useful for carrying or storing it, while the padded headband and ear pads are intended to make it comfortable over longer sessions.
The trade-off is that it is wired only, so it does not offer the A70’s Bluetooth listening or its audio-sharing arrangement. Its listed sensitivity is 98 dB, and the sheet does not provide the same stated wireless-playback flexibility because there is no wireless mode. I would choose it for a basic wired recording setup, not for someone who wants one pair to move easily between studio and wireless use.
The SR850 is a wired, semi-open over-ear headphone built around 50 mm drivers. Its semi-open construction sets it apart from the closed-back Tascam and the A70 listings. I would consider it for musicians who want that design and a self-adjusting headband, especially for listening and reference work in a quieter room.
The listed frequency range is 10 Hz to 30 kHz, and the impedance is 32 ohms. Samson describes the model as a studio reference headphone; the broad range is a specification, not proof that every mix decision will be accurate. Still, it gives shoppers a concrete point of comparison against the other models’ listed ranges. A 1/8-inch-to-1/4-inch adapter is included for connecting to equipment with a larger headphone jack.
The self-adjusting headband avoids a manual adjustment step, while the velour ear cushions distinguish it from the A70’s described protein-leather pads and the Tascam’s padded design. Its semi-open style is the key choice to weigh. It may suit listening where a less enclosed presentation is welcome, but I would not pick it if a closed-back design is central to your recording setup.
It is wired, with no Bluetooth mode or audio-sharing feature listed. That keeps the connection approach simple but limits flexibility outside a studio or listening space. It also is not an active noise-cancelling option. If your search includes the best noise cancelling open ear headphones, note that these four studio models do not provide that feature; the SR850 is semi-open, which is not the same as open-ear wireless listening.
I compared the published connection, design, driver, and frequency-range details for each model.
The order and recommendations are my independent editorial opinion; no brand paid for placement.
Both OneOdio A70 listings specify Bluetooth and up to 72 hours of wireless playback. The Tascam TH-02 and SAMSON SR850 are listed as wired headphones.
The Tascam TH-02 is explicitly described as closed-back. The SAMSON SR850 is semi-open, while the A70 listings identify over-ear construction but do not specify a closed-back design.
The Tascam TH-02 includes a snap-on adapter from 3.5 mm to 6.3 mm, and the SAMSON SR850 includes a 1/8-inch-to-1/4-inch adapter. The A70 listings specify both 3.5 mm and 6.35 mm connections.
The A70’s Bluetooth mode and stated wireless playback time may suit someone who wants to listen away from a studio. But these are over-ear studio headphones, not a listed active noise-cancelling option; shoppers seeking deep bass head phones for commuting should compare fit, sound preferences, and noise-control needs rather than assume a studio label covers them. “Ear clip headphones for nurses” are a different wearing style and use case from all four models here.
For musicians, I recommend the OneOdio A70 when you want one pair for wired studio connections and wireless listening, with the Tascam TH-02 as my simpler pick for closed-back wired monitoring.
