If you want wired, semi-open headphones built around a redesigned planar magnetic driver for calls, choose Amazon Renewed Fostex T50RP; if you need wireless open-ear headphones for calls alongside sports and swimming, choose ERAZERL NE86. The key difference is straightforward: one is a wired listening design, while the other is built around open-ear, activity-focused use.
Amazon Renewed Fostex T50RP vs ERAZERL NE86 at a Glance
• ERAZERL NE86: Its open-ear bone-conduction design, wireless connectivity, and stated IPX8 waterproofing suit active use; the trade-off is that it is a sports-oriented headset rather than an around-ear listening design.
• Choose the T50RP if you want wired headphones with a semi-open back and around-ear pads.
• Choose the NE86 if you want open-ear wireless audio for workouts, outdoor activities, or swimming.
• For calls: choose based on where you take them. The T50RP has a cable; the NE86 is wireless and leaves the ear canal uncovered.
The Amazon Renewed Fostex T50RP is a wired, semi-open-back headphone with a completely redesigned RP planar magnetic driver. Its 4-pole 3.5 mm connector supports balanced connections, and the cable uses OFC conductors. Those details make it the more conventional choice for someone who wants a wired headphone setup and values its particular driver design over wireless freedom.
The thicker, low-resilience, around-ear pads are intended to provide a comfortable fit during longer listening sessions. That design may appeal if you want headphones that sit around the ears rather than an open-ear frame. For calls at a desk, the wired connection may be a sensible fit if your setup accommodates a 3.5 mm connector. The available specifications do not identify a built-in microphone, so I would not choose it on the assumption that it has one.
Its semi-open back is an important part of the decision. This is not the same kind of open-ear design as the NE86: the T50RP uses ear cups and pads, while the NE86 leaves the ear canal uncovered. If your priority is a wireless headset for moving around, or a design explicitly described for swimming and sports, the T50RP is not the match. Its listed weight is 0.52 kg, another detail to consider if you prefer a lighter-feeling setup.
Who should skip it: Skip the T50RP if you need wireless connectivity, an open-ear frame, or stated waterproofing for swimming.
The ERAZERL NE86 is a wireless, open-ear bone-conduction headset aimed at active use. Its design does not block the ear canal, so you can remain more aware of surrounding sounds while listening outdoors. That may suit a runner, cyclist, or walker who does not want conventional in-ear earbuds. The product information also describes a flexible memory-steel-wire back frame intended to fit securely during movement.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The NE86’s stated feature set goes beyond everyday wireless listening: it is described as IPX8 swim waterproof, and its product description includes a heart-rate monitor and TF-card MP3 playback. Those details make it the more activity-oriented option here. Its wireless connection avoids a headphone cable, while the open-ear design differs sharply from the T50RP’s around-ear pads. For calls, it may fit someone who wants to keep the ear canal uncovered, but the provided specifications do not state that it has a built-in microphone or describe call controls.
That sports focus is also its main limitation for buyers seeking a traditional headphone setup. The NE86 is not described as a semi-open, around-ear headphone with a planar magnetic driver. Its open-ear form may be less suitable if you specifically want ear cups and pads for extended listening. And while the product is described as waterproof, that should not be mistaken for a noise-canceling feature; no noise cancellation is listed.
Who should skip it: Skip the NE86 if your priority is a wired, around-ear headphone with a planar magnetic driver.
Side-by-Side: Which Should You Choose?
• Best fit for wired listening → Amazon Renewed Fostex T50RP. It has a cable and a 4-pole 3.5 mm connector; the NE86 is wireless.
• Best fit for an open-ear design → ERAZERL NE86. Its bone-conduction style leaves the ear canal uncovered, unlike the T50RP’s around-ear pads.
• Best for swimming-focused use → ERAZERL NE86. It is described as IPX8 swim waterproof; the T50RP’s supplied details do not state water resistance.
• Best for longer sessions with around-ear pads → Amazon Renewed Fostex T50RP. Its thicker, low-resilience pads are described as suitable for extended listening.
• Best for outdoor awareness while listening → ERAZERL NE86. The open-ear design is intended to let surrounding vehicle and pedestrian sounds remain audible.
• Best for a cable-free workout setup → ERAZERL NE86. It connects wirelessly and is described for activities such as running, gym training, and cycling.
• Best for a call setup with a 3.5 mm connection → Amazon Renewed Fostex T50RP. That is a fit question, not a claim about call quality: neither product’s supplied details confirm a built-in microphone.
For searches such as “best open ear headphones for calls,” the NE86’s open-ear design is the closer match, but its listed information does not specify a microphone. The T50RP is the more natural fit for a wired desk setup if the connected device and call configuration meet your needs. Neither product is described as noise canceling, so shoppers looking for noise canceling gaming headphones for calls should not assume either one provides that feature.
Start with how you plan to connect. The T50RP uses a cable and a 4-pole 3.5 mm connector, with support for balanced connections. Check that your device and intended setup work with that connection before choosing it. The NE86 connects wirelessly, which removes the headphone cable from a workout or outdoor routine, but its supplied information does not specify battery life or wireless range.
Next, consider what “open” means in each design. The T50RP is semi-open back, with around-ear pads. The NE86 is open-ear bone conduction, so the ear canal is not covered. These are not interchangeable descriptions. If staying aware of nearby activity matters, the NE86’s design is more directly suited to that use. If you want ear cups and pads, the T50RP is the relevant option.
Be precise about call needs, too. The intended use in this comparison is calls, but the available specifications for neither product confirm a built-in microphone, call controls, or noise cancellation. A connection type alone does not establish call quality. If calls are the deciding factor, confirm that your planned device and call setup can provide the microphone functionality you need.
Finally, match the trade-offs to your routine. The T50RP brings a cable, a semi-open construction, and a listed weight of 0.52 kg. The NE86 brings a wireless open-ear frame and stated waterproofing for swimming, with features listed for sports use. Neither is a universal substitute for the other: the right choice depends on whether wired, around-ear listening or wireless, open-ear activity matters more to you.
I would choose the Amazon Renewed Fostex T50RP if my priority were wired listening, its planar magnetic driver, and around-ear pads. For calls, though, I would first verify that my intended setup provides a microphone, since one is not specified here. If I wanted wireless open-ear audio for workouts or swimming, I would choose the ERAZERL NE86 instead. My call is the T50RP for a wired desk-based routine, not as a confirmed call-quality winner.
The T50RP has a wired 4-pole 3.5 mm connector, while the NE86 connects wirelessly and uses an open-ear design. Neither product’s supplied details confirm a built-in microphone or call performance, so check that your intended setup supports calls.
Noise cancellation is not listed among the NE86’s provided features. Its open-ear bone-conduction design is intended to leave the ear canal uncovered, which supports awareness of surrounding sounds rather than blocking them.
The NE86 is described as IPX8 swim waterproof. No water-resistance rating is provided for the T50RP, so the supplied information does not support choosing it for swimming.
The T50RP has around-ear pads and a semi-open back. The NE86 uses an open-ear bone-conduction design that does not cover the ear canal, making the two products distinct in fit and intended use.
