If you want wireless listening, active noise cancellation, and longer stretches away from a charger for fishing, choose Amazon Renewed Marshall Monitor II; if you need a wired in-ear fit with passive noise isolation, choose Sony IER-M500. For most fishing outings, I would choose the Marshall because its wireless design and stated battery life are easier to work around outdoors. The Sony makes more sense when a cable is welcome and a close-fitting earphone is the priority.
Neither is a purpose-built fishing headphone based on the available features, so the key question is how you want to listen and what kind of fit you prefer. Think about whether you want an over-ear headphone with active noise cancellation or an in-ear monitor that isolates through its sealed fit. Also consider that neither product’s listed features establish water resistance, so I would not treat either as protected from rain, splashes, or wet handling.
• Amazon Renewed Marshall Monitor II: Over-ear Bluetooth listening, active noise cancellation, and up to 30 hours of wireless playtime with noise cancellation; the trade-off is that it is a larger over-ear design, and its controls and noise reduction may not suit someone who wants a simple wired earphone.
• Sony IER-M500: Wired in-ear fit, multiple ear-tip sizes, flexible ear hangers, and sound isolation; the trade-off is that it has no stated wireless playback or active noise cancellation.
• Choose the Marshall if you want Bluetooth freedom, a rechargeable battery, and a collapsible over-ear design for travel.
• Choose the Sony if you prefer a cable, a secure in-ear fit, and a selection of tips for adjusting how the earphones sit.
• For fishing, the Marshall is my more practical pick for longer listening sessions away from a phone cable; the Sony fits someone who values a compact wired setup and a close, isolating fit.
The Marshall Monitor II is an over-ear Bluetooth headphone with active noise cancellation. Its biggest practical advantage is the combination of wireless listening and a stated battery life of up to 30 hours with noise cancellation enabled, or up to 45 hours without it. That gives a buyer options: use noise cancellation when wanted, or switch it off to extend the stated playback time. The listed charging time is two hours.
For fishing, that mix is useful if you plan to listen for a while and do not want a cable running from your headphones to your phone. The collapsible design and included carrying bag also make it easier to pack away than a fixed, full-size shape. Its multi-directional control knob handles playback, volume, and phone functions, so the main listed controls are grouped into one physical interface rather than requiring a touch surface.
I would choose the Marshall if wireless convenience, active noise cancellation, and longer battery use matter more than having a small in-ear design. I would skip it if you need a headphone specifically confirmed as water-resistant, or if you want to hear your surroundings without active noise cancellation. The product information does not provide a water-resistance claim, and noise cancellation is not the same thing as an awareness or transparency mode. It is also an over-ear model, so it may feel like more to carry than an earphone.
The Sony IER-M500 is a wired in-ear monitor with a 3.5 mm connection. Its design focuses on keeping the earphones positioned securely: it includes flexible ear hangers, fitting supporters, and ear tips in XS, S, M, and L. That range gives you several ways to find a fit that feels stable, although the right result depends on the shape of your ears and the tip you choose.
Sony describes the IER-M500 as a monitoring earphone with balanced sound and strong noise isolation from its sealed structure. In practical terms, its appeal is a direct wired connection and an in-ear fit intended to stay in place through movement. There is no battery or Bluetooth playback listed, so it avoids the need to recharge but keeps you physically connected to the audio source.
I would consider the Sony if you prefer earphones that take up little space, want a choice of tip sizes, and value a secure fit more than wireless freedom. Its sealed design could be useful when you want to reduce outside noise, but that can also be a drawback while fishing if you need to stay attentive to nearby people, movement, or other sounds. I would not pick it for someone who specifically wants active noise cancellation or cable-free use; neither feature is listed for this model.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-18 · 15 min read · Independent comparison
• Best for wireless listening → Amazon Renewed Marshall Monitor II. It uses Bluetooth and is designed to play without a cable attached to the audio source.
• Best for avoiding a charging routine → Sony IER-M500. It is wired, and its listed features do not rely on a rechargeable battery for playback.
• Best for a compact in-ear setup → Sony IER-M500. It sits in the ear and includes a protective case, fitting supporters, and four ear-tip sizes.
• Best for active noise cancellation → Amazon Renewed Marshall Monitor II. Its noise control is specifically listed as active noise cancellation; Sony uses sound isolation from its in-ear structure.
• Best for a fit you can adjust with different tips → Sony IER-M500. The XS, S, M, and L tips offer more listed sizing choices than the over-ear Marshall.
• Best for one physical control knob → Amazon Renewed Marshall Monitor II. Its multi-directional knob is listed for playback, volume, and phone functions.
• Best for fishing when you want a cable-free connection → Amazon Renewed Marshall Monitor II. The Sony’s wired connection may be perfectly acceptable, but it does keep the earphones tethered to the connected device.
A fishing setting makes the noise-control difference especially important. Active noise cancellation and passive isolation both reduce outside sound in different ways, but neither should be mistaken for a feature that helps you hear your surroundings. If staying aware of nearby activity is important, I would keep that in mind before choosing either one. The provided features do not list an ambient-sound mode for the Marshall or a hear-through option for the Sony.
Fit is another deciding factor. The Marshall covers the ears, folds for packing, and includes a carry bag. The Sony rests inside the ears and uses supports that contour around them. Someone who dislikes an in-ear seal may prefer the over-ear Marshall, while someone who dislikes carrying headphones may favor the smaller Sony. Those are different wearing styles, not interchangeable versions of the same design.
For a shopper searching for the best open ear earbuds for fishing, neither product fits that description: the Sony is a sealed in-ear monitor, and the Marshall is an over-ear headphone. Likewise, neither is an open-ear design intended to leave the ear uncovered. If you are comparing the best on ear headphones for fishing, note that the Marshall is over-ear, not on-ear. And if your search is for the best touch control headphone for fishing, the Marshall’s listed control is a multi-directional knob, not touch control. The product names and controls matter because these labels describe different wearing styles and interaction methods.
My Verdict
In my opinion, I would buy the Amazon Renewed Marshall Monitor II for fishing because Bluetooth, active noise cancellation, and up to 30 hours of stated playback with cancellation give it the more flexible long-session setup. Its collapsible design and carrying bag also help when I want to pack it away between uses. I would choose the Sony instead if I specifically wanted a wired in-ear fit with multiple tip sizes and no need to recharge. For fishing, my recommendation is the Marshall, with the clear caveat that neither product is listed as water-resistant.
I would choose the Marshall for cable-free listening and its stated wireless playback time. The Sony is a reasonable alternative if you prefer wired earphones and a secure in-ear fit. Neither product’s listed features confirm water resistance.
No active noise cancellation is listed for the IER-M500. Its noise reduction comes from sound isolation created by the sealed in-ear design and selected ear tips.
Yes. The listed package includes a removable 3.5 mm cable as well as a USB-C charging cable. The headphone also supports Bluetooth wireless connectivity.
They use different approaches, so the feature descriptions do not establish a direct measured comparison. The Marshall has active noise cancellation; the Sony relies on passive sound isolation from its in-ear fit. Which approach suits you depends on whether you want over-ear headphones or sealed earphones.
