If you want adjustable sound tuning and a metal-bodied design, choose HIFIXAUDIO SIMGOT EA500LM; if you need a comfort-focused fit with included accessories, choose NFACOUS NA20. For jogging, I would lean toward the EA500LM for its compact in-ear format and three tuning options, while the NA20 makes more sense if its ergonomic shape and bundled fit options matter more to you.
HIFIXAUDIO SIMGOT EA500LM vs NFACOUS NA20 at a Glance
• NFACOUS NA20 strength: It pairs an ergonomic in-ear shape with four pairs of ear tips and a storage case. Trade-off: It does not offer the EA500LM’s three interchangeable sound-tuning nozzles.
• The EA500LM has a metal body and detachable cable; the NA20 uses a frosted polycarbonate body with CNC-carved aluminum parts and a 6N OFC cable.
• Both are wired, single dynamic-driver in-ear monitors. Neither is an on-ear headphone, and neither is a wireless jogging option.
• Choose the EA500LM if sound adjustment and its metal construction appeal to you. Choose the NA20 if fit options, an ergonomic shape, and the included adapter and storage accessories are more important.
The EA500LM is an in-ear monitor built around a second-generation dual-magnetic-circuit, dual-cavity dynamic driver and a lithium-magnesium dome diaphragm. Its headline feature is the set of three interchangeable nozzles. They give you a practical way to adjust the sound rather than locking you into one presentation: the available tunings include warmer and fuller, calmer and more neutral, and livelier with more emphasis on vocal presence and high-frequency air.
That flexibility is useful if you listen to several kinds of music or want different presentations for games and everyday listening. The product information also describes the EA500LM as suitable for casual listening, monitoring, and recording. Its metal body is designed to protect the internal components, while the detachable cable gives you a way to replace the cable rather than treating it as permanently fixed. The specified frequency range is 10 Hz to 50 kHz, with an effective range of 20 Hz to 20 kHz.

For jogging, the compact in-ear format may suit someone who prefers small wired earbuds over a bulky headset. But the available information does not establish a water-resistance rating, a cable-management feature, or a secure sports-specific fit. I would not choose it on the assumption that it is built for sweat or vigorous movement. It is also not a conventional with mic gaming headphones for jogging: the listed cable and remote details do not establish that a microphone is included.
The EA500LM is the more natural pick if you value changing the sound signature and want the durability-minded metal enclosure. Skip it if you want wireless freedom, documented sports protection, or a fit specifically engineered for running.
The NA20 is another wired, single dynamic-driver in-ear monitor, but its emphasis is different. Its MC2L-100M driver uses a beryllium-plated diaphragm, and the design includes a system of pressure-controlling damping nets and tuning sponges intended to manage reflected sound. The maker also describes an integrated tuning circuit designed to improve adaptability across different music styles. Its stated frequency range is 20 Hz to 40 kHz.
The physical design combines a frosted, high-strength polycarbonate body with CNC-carved aluminum parts. The shape is described as ergonomic for extended listening or mixing sessions. In the box, the NA20 includes four pairs of ear tips in XS, S, M, and L, a storage case, and an adapter for use with a 6.35 mm connection. Those accessories make it easier to work through different tip sizes and to store or connect the earphones in different setups.
For jogging, the supplied tip choices could help you find a more suitable fit, but they do not prove that the NA20 will stay secure during a run. The product details do not list a water-resistance rating or wireless connectivity. The earphones use a wired 6N OFC cable, so you will still need to manage a cable while moving. The NA20 is worth considering if comfort, included fit options, and a less metal-dominant body appeal to you. Skip it if interchangeable tuning nozzles are a priority or you need a purpose-built wireless sports set.
Side-by-Side: Which Should You Choose?
• Best for adjusting sound with interchangeable parts → HIFIXAUDIO SIMGOT EA500LM. Its three nozzles provide distinct tuning options, including warmer, more neutral, and livelier presentations.
• Best for a metal-bodied enclosure → HIFIXAUDIO SIMGOT EA500LM. Its shell is described as a metal alloy body with CNC finishing.
• Best for an ergonomic shape emphasized for longer sessions → NFACOUS NA20. Its design description specifically focuses on a comfortable fit for extended listening and mixing.
• Best for a detachable cable → HIFIXAUDIO SIMGOT EA500LM. The cable is listed as detachable, which may be useful if you want to replace it.
• Best for bundled connection and storage accessories → NFACOUS NA20. It includes a carrying case and a 6.35 mm adapter.
• Best for a headphone for jogging if you prefer compact wired earbuds → HIFIXAUDIO SIMGOT EA500LM. Its in-ear form is more portable than a traditional over-ear gaming headset, though neither model is specified as a sports or sweat-resistant product.
• Best for a wired setup with a stated passive noise-control feature → NFACOUS NA20. Its product information lists passive noise cancellation; the EA500LM lists sound isolation.
The most important distinction is not that one is universally more capable. It is what you want to adjust. The EA500LM gives you three nozzle-based tuning choices and a detachable cable. The NA20 puts more emphasis on ergonomic shaping, tip-size variety, and included accessories.
Neither model offers Bluetooth in its listed connectivity details. That matters more for jogging than small differences in driver construction: both require you to manage a cable, and the supplied information does not confirm sweat protection or a dedicated running fit. If those are must-haves, neither should be treated as a purpose-built sports earphone based on the available specifications.
I would choose the HIFIXAUDIO SIMGOT EA500LM for its three distinct tuning options, metal enclosure, and detachable cable. For jogging, its compact in-ear form is appealing, but I would still account for the cable and avoid assuming it has sports-rated protection. The NA20 is the better fit if its ergonomic design, four ear-tip sizes, and included storage accessories matter more to you. My overall pick is the EA500LM because its tuning flexibility gives me a clearer reason to choose it over a conventional fixed-tuning wired earphone.
FAQ
No. Both are presented as wired in-ear monitors. Their product details do not identify Bluetooth as the connection method, so neither offers the cable-free setup many runners prefer.
The EA500LM has three interchangeable tuning nozzles, each associated with a different sound presentation. The NA20 uses damping components and an integrated tuning circuit, but it does not list a set of interchangeable tuning nozzles.
The NA20’s design description specifically highlights an ergonomic shape intended for extended listening or mixing, and it includes four ear-tip sizes. That gives you several fit options, though comfort remains personal. The EA500LM’s product information does not make the same specific long-session comfort claim.
