• Direct Sound EX-29 — biggest strength: Extreme passive isolation (36.7 dB attenuation at 8,000 Hz, NRR 29 dB) from a closed-back 40 mm dynamic driver design, no batteries or active circuitry required.
• Direct Sound EX-29 — biggest trade-off: It is a single-purpose wired tool. No USB, no effects, no mixer — just headphones, a cable and a screw-on adapter.
• Mackie ProFX10v3 — biggest strength: A complete 10-channel USB mixer bundle with 24 FX options, 60 dB of gain, single-knob compression and 24-bit/192kHz recording, plus a set of closed-back monitor headphones and cables in the box.
• Mackie ProFX10v3 — biggest trade-off: The headphones are a bundled accessory, not the main event. If isolation is your goal, they are not the headline product here.
• Who each pick is for: Direct Sound EX-29 for drummers, tracking musicians and anyone who needs to shut the world out; Mackie ProFX10v3 for podcasters, singer-songwriters and small studios that need a mixer and want headphones included.
The EX-29 is a closed-back dynamic headphone with 40 mm drivers, a 32 Ohm impedance rating and a frequency response of 20 Hz to 20 kHz. What sets it apart is the isolation. Direct Sound rates it at 36.7 dB of passive attenuation at 8,000 Hz and an NRR of 29 dB. That is a huge number, and it comes from the physical design — closed cups, dense materials, no active noise cancellation chip, no batteries. In practice that means you can stand next to a live drum kit, a loud amp or a noisy room and still hear a click track or a monitor mix clearly.
Who should buy it: drummers, tracking engineers, live performers, and parents buying for a child who plays a loud instrument and needs real hearing protection while still hearing playback. Who should skip it: anyone who wants to record, mix or stream without a separate interface — this is headphones only, and it is wired, so there is no wireless convenience here.
Mackie ProFX10v3: Who It's For
This is a bundle, and the headline item is the mixer, not the headphones. The ProFX10v3 is a 10-channel unpowered USB mixer with XLR inputs, up to 60 dB of gain for ultra-low noise performance, 24 built-in FX options spanning reverbs and delays, single-knob compression for keeping levels consistent, and a 24-bit/192kHz 2x4 USB recording interface. It runs on corded electric power. The bundle also includes a pair of Knox Gear TX-100 closed-back studio monitor headphones, two 1/4" TRS cables and two XLR cables — six items total.
For someone setting up a first home studio, that combination is genuinely useful. You get the mixer, the monitoring headphones, and the cables you would otherwise have to buy separately, all matched to the same job. The XLR inputs suit microphones and DI sources, the compression knob helps a beginner keep vocals and instruments from clipping, and the USB interface means the mixer doubles as your recording front end without a separate audio interface.
Who should buy it: podcasters, singer-songwriters, small bands recording demos, streamers, and anyone building a starter studio who wants the mixer, headphones and cables resolved in a single purchase. Who should skip it: someone who only needs isolation headphones for tracking or practice. If that is you, the mixer is money spent on gear you will not use.
Side-by-Side: Which Should You Choose?
• Best for maximum noise isolation → Direct Sound EX-29. 36.7 dB passive attenuation and NRR 29 dB are the whole point of this headphone.
• Best for a live tracking session → Direct Sound EX-29. Closed-back 40 mm drivers, 32 Ohm impedance and high 114 dB sensitivity make it easy to drive from a headphone amp or interface.
• Best for a first studio setup → Mackie ProFX10v3. Mixer, monitor headphones and cables arrive together, so you are not chasing parts.
• Best for built-in effects and compression → Mackie ProFX10v3. 24 FX options plus single-knob compression are onboard.
• Best for battery-free, always-works reliability → Direct Sound EX-29. Passive isolation with no power, no charging, no firmware.
• Best for kids learning an instrument → Direct Sound EX-29. For a young drummer or a child practicing a loud instrument, real passive isolation protects young ears while still letting them hear a backing track. If you are also weighing lighter listening gear for a child — the kind of thing people search for as the best true wireless earbuds for children, or the best touch control neckband headphones for children — remember those are listening devices, not hearing protection. The EX-29 is the protective tool.
• Best for a child who needs a recorder, not protection → Mackie ProFX10v3. A teenager recording their first songs gets a mixer, headphones and cables in one shot.
In my opinion, the Direct Sound EX-29 is the better buy for anyone whose real problem is noise. It does one job — shutting out the world while you hear your mix — and the isolation figures back that up. If your goal is protecting a child's hearing during practice, I would pick the EX-29 without hesitation. If instead you need to actually record, mix and route audio, I would buy the Mackie ProFX10v3, because the mixer is the product and the headphones are a useful bonus. Buy the tool that matches the job, not the one with more items in the box.
Closed-back headphones have sealed earcups that block sound from entering and keep your audio from leaking out. The Direct Sound EX-29 is a closed-back dynamic design rated for 36.7 dB of passive attenuation and an NRR of 29 dB, and the Knox Gear TX-100 included with the Mackie bundle is also a closed-back monitor headphone.
That depends on the job. In my opinion, if your priority is isolation for tracking or practice, the Direct Sound EX-29 is the stronger pick thanks to its passive attenuation rating and foldable, adjustable design. If you need monitoring as part of a recording setup, the headphones bundled with the Mackie ProFX10v3 cover that role.
Closed-back designs seal around the ear to block outside noise and prevent bleed, which is why they suit tracking and loud environments like the EX-29. Open-back headphones trade that isolation for a more spacious, airy sound, but they leak audio and let room noise in, so they are a poor fit for recording near a microphone.
They are closed-back studio monitor headphones included alongside the mixer, two TRS cables and two XLR cables. They are a sensible monitoring option for the mixer, but they are not rated for the extreme passive isolation the EX-29 is built around, so treat them as a bundle accessory rather than a dedicated isolation tool.
