How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a set of high-isolation over-ear headphones built to shut the world out and run straight off a phone or laptop, choose Direct Sound EX29; if you need a proper recording interface that feeds your mic, guitar and a pair of high impedance studio headphones with clean, loud playback, choose Focusrite Scarlett Solo 4th. These are two genuinely different tools, and I want to be blunt about that up front — one is a listening device, the other is a recording device. If you're shopping for yourself and you're a senior who mostly wants comfortable over-ear headphones for music, TV and quiet focus, the EX29 is the one that fits that job. The Solo is for the person making music, not just hearing it.
• Direct Sound EX29 — biggest strength: 29 dB of passive sound isolation with no batteries, ever. It's a closed-back, wired, foldable over-ear headphone that simply keeps outside noise out.
• Direct Sound EX29 — biggest trade-off: It's wired only, needs no power but also offers no amplification, no software, and no recording inputs. It's a listener's tool, not a creator's.
• Focusrite Scarlett Solo 4th — biggest strength: It's a USB audio interface with a mic preamp, a Hi-Z instrument input, 24-bit/192 kHz conversion and a headphone amp explicitly designed to drive high impedance headphones louder and clearer.
• Focusrite Scarlett Solo 4th — biggest trade-off: It has no earcups, no drivers and no isolation. Without headphones or a mic plugged in, it makes no sound at all.
• Who each pick is for: The EX29 is for anyone who wants to block out a noisy room and just listen — including many older buyers who want simple, rechargeable-free, over-ear comfort. The Solo is for the guitarist, vocalist or producer who needs to actually record.
The EX29 is a purpose-built isolation headphone. It's a dynamic, closed-back design with a frequency range of 20 Hz to 20,000 Hz, and its headline feature is 29 dB of passive isolation. Passive is the key word here. There are no batteries, no charging, no power levels to manage — you plug in and the outside world gets quieter. In my opinion, that's exactly the kind of simplicity that makes a headphone easy to live with day after day.
The physical design backs this up. It has an IncrediFlex padded, fully adjustable headband and it folds for storage, which makes it practical to toss in a bag or a drawer. The cable ends in a gold-plated 3.5 mm jack with a screw-on 1/4" adapter, so it works with phones, laptops and tablets as well as a bigger audio setup. It weighs 1.1 pounds and comes in white. The over-ear, closed-back shape is what does the noise-blocking work.
Focusrite Scarlett Solo 4th: Who It's For
The Scarlett Solo 4th Gen is a small USB audio interface — roughly 5.63" wide, 3.78" deep and 1.83" tall, weighing 14.4 ounces. It has one XLR mic preamp and one Hi-Z instrument input, which is the classic songwriter's combo: plug in a microphone and a guitar and start recording. It runs over USB and works with Mac, Windows and iPad, and it supports up to 24-bit/192 kHz with a 120 dB dynamic range. That dynamic range figure is the one I'd point at when someone asks why recordings from this class of interface sound clean — it describes how much space there is between the quietest detail and the loudest peak.
The feature that matters most for this comparison is the headphone output. Focusrite states the custom-designed headphone amp drives high impedance headphones louder and clearer than before. That's the entire reason this interface keeps coming up in conversations about high impedance studio headphones. If you own a pair of high impedance cans — the kind that sound thin and quiet plugged into a laptop jack — this is the box that's built to feed them properly.
There's also Air mode, which lifts vocals and guitars forward in the mix with added presence and harmonic drive. The Dynamic Gain Halos make setting levels quick and visual. And the box includes a genuinely deep software bundle: Pro Tools Intro+, Ableton Live Lite, Cubase LE and the Hitmaker Expansion with effects, instruments and mastering tools. Who should buy it? The guitarist, vocalist or producer who wants to record at home. Who should skip it? Anyone who just wants to listen to music. Without headphones or monitors plugged in, it's silent. And if you want a rechargeable bluetooth set for casual listening, this is the wrong category entirely.
• Best for blocking out a noisy room → Direct Sound EX29. 29 dB of passive isolation with no power needed is the whole point of this headphone.
• Best for driving high impedance studio headphones → Focusrite Scarlett Solo 4th. Its headphone amp is specifically designed to push high impedance headphones louder and clearer.
• Best for zero-maintenance simplicity → Direct Sound EX29. No batteries, no drivers, no software, no pairing. Plug in and go.
• Best for a studio-quality playback chain → Focusrite Scarlett Solo 4th. 24-bit/192 kHz conversion and 120 dB dynamic range give you a clean, wide path from source to headphones.
• Best for someone who wants one purchase that just works with a phone → Direct Sound EX29. The 3.5 mm jack with a screw-on 1/4" adapter covers both consumer and pro sockets.
• Best for portability inside a studio or desk setup → Focusrite Scarlett Solo 4th. Small footprint, USB powered, and the EX29 folds flat when you're not using it.
• Best for a senior who wants comfortable, wired over-ear listening → Direct Sound EX29. Simple, adjustable, padded and no charging routine to remember.
My Verdict
If I had to pick one for a senior who wants to sit down and enjoy music, TV or a quiet hour without fighting a noisy house, I'd buy the Direct Sound EX29. It's the simpler product for the simpler job: over-ear, closed-back, adjustable, and it blocks a serious amount of outside sound without ever needing a charge. I'd only steer you to the Focusrite Scarlett Solo 4th if you actually record — and specifically if you own high impedance studio headphones that need a proper amp behind them. Different tools, different buyers. Check the current price on Amazon before you commit, since that's the one thing that can swing the decision either way.
do high impedance headphones sound better
Not automatically. Impedance isn't a quality rating — it describes how much electrical resistance the headphone presents. What matters is matching the headphone to a source that can drive it. High impedance headphones often sound their best when paired with an amp designed for them, like the headphone output on the Scarlett Solo 4th, which Focusrite built to drive high impedance headphones louder and clearer. Feed the same headphone from a weak laptop jack and it can sound thin and quiet.
is high impedance good for headphones
It can be, in the right setup. Higher impedance designs tend to pair well with dedicated headphone amps and studio gear, which is why they show up in recording environments. The trade-off is that they demand more voltage to reach a given volume, so a plain phone or laptop output may not get them loud enough. The Scarlett Solo 4th addresses this directly with its custom headphone amp.
are high impedance headphones better
Better for some things, not for everything. If you're mixing or recording and you have an interface that drives them properly, high impedance headphones can be an excellent choice. If you just want to plug into a phone and listen casually, a lower impedance headphone is usually the easier path. The Direct Sound EX29, for example, is a wired closed-back headphone designed to plug straight into a 3.5 mm jack — no amp required.
why are high impedance headphones better
When they are better, it's usually because of how they interact with the gear driving them. A higher impedance load can reduce the effect of a weak or noisy output stage, and pro interfaces are often built with that load in mind. Focusrite's spec sheet for the Scarlett Solo 4th says its headphone amp drives high impedance headphones louder and clearer. So the honest answer is: they're better when your source is designed for them — and less convenient when it isn't.
If you're weighing a rechargeable bluetooth set or best sports earbuds for seniors against these two, note that neither product here is wireless — the EX29 is wired and the Solo is a USB interface. They solve different problems, and knowing which problem is yours is most of the decision.
