GREYOLK is my pick for headphones nylon cord shoppers playing Xbox because its open-ear design, Bluetooth, and built-in MP3 storage suit active listening beyond the console. SIMJAR is the runner-up if you want over-ear headphones with a microphone and a wired option.
headphones nylon cord at a Glance
• SIMJAR Kids — best for kids’ listening and calls; pick this if you want over-ear coverage, a volume limiter, and wired or wireless use.
• FiiO FH9 — best for wired music listening; pick this if you want a detachable cable, hybrid drivers, and swappable plugs.
GREYOLK is an open-ear bone-conduction headset built for swimming, running, and other activities where sealed earbuds may be less suitable. Its IP68 waterproof rating makes it the most clearly water-oriented option here. The listed Bluetooth version differs between product details and feature information, so I would not rely on a particular version number when comparing it.
The key practical detail is that Bluetooth does not work underwater. For swimming, you need to switch to MP3 mode and use the built-in 32 GB memory. The storage supports MP3, WMA, WAV, APE, and FLAC files, and the headset can connect to a computer by its magnetic charging cable to manage the internal music library. That makes it better suited to prepared playlists than streaming lapside.
For land use, Bluetooth provides a stated range of up to 10 metres. The open-ear design leaves the ears uncovered, which can help you remain aware of nearby sounds during a run or workout. The listed battery life is up to eight hours, with a charging time of about 1.5 hours. At 32 grams, it is also designed to stay lightweight for activity.
The trade-off is its specialized approach. It is not an over-ear gaming headset, and the product information does not establish Xbox compatibility or describe a gaming microphone. If your main goal is voice chat or wireless console audio, I would not choose it on the basis of its sports features alone. Still, among these three, it offers the clearest mix of Bluetooth listening on land and self-contained playback in water.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
SIMJAR is an over-ear wireless headset aimed at children, with a built-in microphone, a volume limiter, and a foldable design. Its ear cushions are described as soft and breathable, while the over-ear fit provides more coverage than GREYOLK’s open-ear frame. That makes it a more natural candidate for tablet use, travel, online lessons, or casual listening at home.
The product describes two volume-limit settings, 85 dB and 94 dB. That gives a parent a way to choose a listening limit, though a limiter is not a guarantee that every listening situation is harmless. The built-in microphone is useful for calls and online lessons. For Xbox, the microphone and the included 3.5 mm audio cable make it the most plausible pick of the three for wired play, but the specifications do not confirm compatibility with a particular Xbox console, controller, or chat setup.
SIMJAR can be used wirelessly over Bluetooth or connected by its 3.5 mm cable. That flexibility can be handy when a wireless connection is not preferred or when the battery needs a break. The product lists Bluetooth range up to 10 metres and up to 50 hours of playtime in its feature information. Product details also report a different battery-life figure, so I would treat the longer claim cautiously rather than assume a precise runtime.
Its main compromise is that it is a children’s over-ear headset, not a gaming model built specifically for console use. There is no listed noise control, and the available information does not spell out Xbox voice-chat behavior. For someone searching for Bluetooth over ear headphones for Xbox, SIMJAR’s form and microphone are relevant, but checking the intended wired connection with your setup matters. It is also the most child-focused choice here, rather than a general-purpose sports headset.
FiiO’s FH9 is a wired in-ear monitor with a detachable cable and a hybrid driver design: one dynamic driver and six balanced-armature drivers. Its titanium-alloy construction and stainless-steel angled MMCX connectors are intended for a secure, considered fit. The included cable is described as pure silver with a TPU outer sheath. This is the most audio-focused design of the three, rather than a simple wireless sports or children’s headset.
The detachable cable and included 2.5 mm, 3.5 mm, and 4.4 mm swappable plugs give it more connection flexibility than a fixed-plug earphone. The listed accessories include several types of ear tips, including balanced, bass, foam, SpinFit, and vocal options. Those choices let the listener vary fit and feel, although the product details do not establish that every plug or configuration will work directly with every console.
For Xbox, the 3.5 mm plug is the connection detail most likely to matter, especially for a controller with a compatible headphone jack. But the FH9’s published information does not describe a built-in microphone or confirm voice-chat support. I would consider it for wired game audio only if the connection and chat needs of your setup are already clear. It is not a Bluetooth headset, despite Bluetooth appearing in one product-information field; the product title and cable details identify it as wired.
The trade-off is therefore straightforward: the FH9 offers a replaceable cable and multiple plug options, but it is an in-ear wired monitor rather than an over-ear gaming headset. It is also not designed around swimming, a volume limiter, or long wireless sessions. If your priority is detailed wired listening across compatible devices, its design has appeal. If you need a headset microphone for Xbox chat, the listed specifications leave an important question unanswered.
I compared the listed designs, connection options, battery and storage details, and stated use cases.
The ranking is my independent editorial opinion based on those specifications.
No brand paid for placement.
SIMJAR has an over-ear design, a built-in microphone, and a 3.5 mm cable, while FiiO offers wired audio through swappable plugs. Neither listing confirms compatibility with a specific Xbox setup, so check the connection and chat requirements for your console and controller.
Can GREYOLK play music over Bluetooth while swimming?
No. Its product information says Bluetooth is not supported underwater. You need to switch to MP3 mode and play audio stored in its built-in memory.
None is described as an ear-clip headset, and none is specifically presented as an Xbox headset. SIMJAR is over-ear and lists up to 50 hours in its feature information, while GREYOLK lists up to eight hours; FiiO is wired.
GREYOLK is the activity-focused choice in this group: it has an open-ear design, a lightweight frame, and IP68 waterproofing. It may suit running or swimming better than SIMJAR or FiiO, but swimming requires MP3 mode rather than Bluetooth.
My final recommendation for Xbox is GREYOLK if you want the most versatile open-ear option for sports and stored music, not a dedicated chat headset. If Xbox voice chat is central, SIMJAR’s microphone and wired option are more relevant, provided the connection suits your setup; sports earbuds for Xbox should not be assumed to support chat just because they connect wirelessly.
