If you want wired in-ear listening with adjustable sound, choose FiiO FH5s; if you need closed-back headphones for recording and monitoring, choose beyerdynamic s DT 770. For a big head, the beyerdynamic’s over-ear construction and adaptable padded headband are the more relevant fit clues, while the FH5s avoids a headband altogether.
These are very different tools, not two versions of the same headphone. I’d choose based on whether you want compact in-ear monitors or a studio-style over-ear pair.

• FiiO FH5s strength: Three tuning switches offer eight sound combinations; trade-off: it is an in-ear design, so it may not suit listeners who dislike ear tips.
• beyerdynamic s DT 770 strength: Closed-back over-ear construction and a replaceable cable suit recording and monitoring; trade-off: it is a larger, headband-based headphone rather than a compact earphone.
• FiiO FH5s sound: Separate dynamic drivers handle low and mid frequencies, with a Knowles balanced armature for treble; trade-off: it is wired, with no listed wireless listening.
• beyerdynamic s DT 770 sound: The STELLAR.45 dynamic driver is specified across 5–40,000 Hz; trade-off: it has no listed sound-tuning switches.
• Who should pick FiiO: A listener who wants in-ear monitors, tuning flexibility, and interchangeable plug options.
• Who should pick beyerdynamic: A listener who wants closed-back over-ear headphones for studio work and values a padded, adjustable headband.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The FH5s is for someone who wants a wired in-ear monitor with more say over its sound than a fixed tuning usually allows. Three switches let you adjust the low, mid, and high ranges, creating eight possible combinations. That gives listeners room to tailor the presentation to different music or personal preferences without changing headphones.
Its driver layout is another defining feature. A 12 mm beryllium-plated dynamic driver handles bass, a 6 mm beryllium-plated dynamic driver covers the midrange, and a Knowles balanced armature handles treble. The rear cavity is semi-open, a design intended to relieve pressure and support longer listening sessions. Its twist-lock plug system can switch among 2.5 mm, 3.5 mm, and 4.4 mm connections.
I’d consider the FH5s if you prefer in-ear listening and want adjustable sound with multiple plug choices. I’d skip it if you specifically want padded cups around your ears, or if the physical sensation of in-ear monitors is a deal-breaker. It is not a wireless sports model, and the available details do not specify a microphone. So shoppers searching for the best wireless sports earbuds for big head or the best with microphone in ear earbuds for big head should not assume this FiiO fits those needs.
The beyerdynamic s DT 770 is the more natural choice for home-studio tasks such as recording and monitoring. Its closed design is intended for those uses, and its STELLAR.45 dynamic driver has a stated frequency range of 5–40,000 Hz. The described sound signature combines powerful bass with detailed highs, while the driver is designed to keep distortion low even at high sound pressure.
For someone asking about headphones for big head, this model has a useful design detail: its memory-foam headband is meant to adapt to the shape of the wearer’s head. Velour ear pads and the spring-steel headband construction are also specified, with comfort intended to hold up during long sessions. The cable detaches, and the headband and ear cushions can be replaced.
I’d look at the DT 770 if you want full-size closed-back headphones, especially for recording or monitoring, and prefer padded over-ear contact to in-ear tips. Its trade-off is straightforward: it is still a wired, over-ear model, so it is less compact than the FH5s. The specifications do not list wireless listening or adjustable sound switches. The adaptable headband is a fit consideration, not a guarantee that every larger head will find it comfortable.
• Best for in-ear listening → FiiO FH5s. Its rounded-tip in-ear format avoids a headband and ear cups.
• Best for recording and monitoring → beyerdynamic s DT 770. Its closed design is specifically described for those studio uses.
• Best for changing the sound profile → FiiO FH5s. Three switches provide eight possible sound combinations.
• Best for a padded over-ear fit → beyerdynamic s DT 770. It combines velour ear pads with a memory-foam headband designed to adapt to the head.
• Best for swapping connection plugs → FiiO FH5s. Its twist-lock system supports 2.5 mm, 3.5 mm, and 4.4 mm plug heads.
• Best for a detachable cable → beyerdynamic s DT 770. Its cable detaches, and the headband and ear cushions are also replaceable.
• Best for a big-head shopper who wants no headband → FiiO FH5s. It removes headband fit from the decision, though in-ear comfort remains personal.
• Best for a big-head shopper seeking over-ear headphones → beyerdynamic s DT 770. The adaptable padded headband makes it the more relevant design, but fit cannot be guaranteed from specifications alone.
I would choose the beyerdynamic s DT 770 for a big-head shopper who wants over-ear headphones, because its memory-foam headband is designed to adapt and its closed construction suits recording and monitoring.
I’d choose the FiiO FH5s instead if I wanted in-ear monitors, sound-tuning switches, and interchangeable plug options.
My deciding factor is the wearing style: these products solve different problems, and neither is a universal replacement for the other.
