If you want a retro on-ear headphone that pairs with two devices at once and streams near-lossless audio over LDAC, choose FiiO EH11; if you need sweat-resistant ear-hook earbuds for running and workouts with a charging case, choose Yechiry BT 5.4.
• FiiO EH11 biggest strength: LDAC hi-res Bluetooth at up to 990kbps, a 40mm long-stroke dynamic driver with bass extension down to 17Hz, and a genuinely light 92g on-ear build.
• FiiO EH11 biggest trade-off: It is an on-ear headphone, not a sealed in-ear, and it carries no water-resistance rating — so it is not the one to grab for a sweaty run.
• Yechiry BT 5.4 biggest strength: A sport-first ear-hook shape with a sealed, coated rear cavity built to shrug off sweat, splashes and light rain, plus a charging case that doubles as storage.
• Yechiry BT 5.4 biggest trade-off: Roughly 5–6 hours per charge in the buds, and a 90-day manufacturer warranty rather than a full year.
• Pick FiiO EH11 if you listen at a desk, on a commute or through long indoor sessions and care about codec quality, app EQ and dual-device switching.
• Pick Yechiry BT 5.4 if you want something that stays hooked to your ears through runs, gym sessions and bad weather.
The EH11 is built around a custom low-frequency design: a 40mm long-stroke dynamic driver with a high-damping composite diaphragm, a resonance frequency dropped to 60Hz, and bass extension down to 17Hz. The semi-open back is the interesting part — it keeps some sense of openness in the sound while still giving you a measure of listening privacy. If you have used open-back headphones before, you know the trade: a wider, airier feel, at the cost of some isolation. That makes the EH11 a poor fit for a noisy train and a great fit for a quiet room.
On the wireless side, LDAC support at up to 990kbps is the headline. That is roughly three times the data rate of standard SBC/AAC, which is what makes near-lossless streaming plausible on a headphone like this — provided your phone or player supports LDAC in the first place. Dual-device connection means you can hold a phone and a computer at the same time and switch between music, calls, gaming and video without re-pairing. The FIIO Control App adds EQ presets like Pop and Rock, plus a gaming mode tuned to push footstep and gunshot detail forward, with a built-in HD mic for calls and team chat.
Who should buy it: someone who wants one headphone for desk work, calls and casual gaming, values codec quality and app tuning, and prefers a physical knob over touch controls. Who should skip it: runners, gym-goers and anyone who needs water resistance or deep noise isolation — the EH11 has neither, and its noise control field is listed as none.
Yechiry BT 5.4: Who It's For
The Yechiry BT 5.4 goes the other direction entirely. These are in-ear, ear-hook earbuds, and the hook is the point: it holds the bud in place without relying on a deep seal, which is why this shape shows up so often in running and workout gear. The brand's own framing is that you stay connected to your surroundings while listening — useful on a road or a shared gym floor.
Sound comes from a 13mm large dynamic driver, which the spec describes as delivering powerful bass, clear treble and a wider frequency response with layered detail. A bigger driver in an in-ear usually means more low-end weight than a tiny driver can manage. Bluetooth 5.4 is the connection standard here, with the spec claiming double the speed at 2 Mbps and a 40% reduction in delay for smoother video and game synchronization. If you have ever watched lip-sync drift on cheap buds, that latency figure is the one to care about.
Battery is split in a way worth understanding: 5–6 hours per charge in the earbuds themselves, with the charging case adding capacity and acting as storage when they are not in use. That is a normal arrangement for this category, and it means the case lives in your bag rather than on a shelf. The sports claim is backed by a sealed rear cavity with coating, designed to keep out sweat, splashing water and light rain. Touch controls handle playback without reaching for your phone.
The trade-offs are equally clear. The warranty is 90 days from the manufacturer, which is shorter than the year FiiO offers. There is no app, no EQ customization and no dual-device pairing mentioned. And the in-ear, hooked fit is not everyone's idea of comfortable for a full workday at a desk.
Who should buy it: runners, cyclists, gym regulars and anyone who wants buds that survive sweat and drizzle and stay put while moving. Who should skip it: listeners who want hi-res codecs, app-based sound tuning or a single pair that covers both the office and the trail.
• Best for sound quality on supported sources → FiiO EH11. LDAC at up to 990kbps and a 40mm driver with 17Hz bass extension is a fundamentally different proposition from standard Bluetooth audio.
• Best for workouts and rain → Yechiry BT 5.4. The sealed, coated rear cavity and ear-hook fit are designed specifically for sweat, splashes and light rain.
• Best for long listening sessions → FiiO EH11. Up to 30 hours on a 1.5-hour charge, at 92g with 1.7N clamping force, is built for all-day wear.
• Best for gaming latency → Yechiry BT 5.4. Bluetooth 5.4 with a claimed 40% delay reduction targets video and game sync; the EH11 counters with an app-based gaming mode instead.
• Best for two devices at once → FiiO EH11. Simultaneous phone-plus-computer pairing with no re-pairing is a feature the Yechiry simply does not list.
• Best for storage and portability → Yechiry BT 5.4. The charging case stores and tops up the buds; the EH11 is a full-size on-ear that lives on a hook or in a bag.
• Best for tuning the sound to your taste → FiiO EH11. FIIO Control App EQ presets versus touch control only on the Yechiry.
• Best for warranty confidence → FiiO EH11. One year versus 90 days.
In my opinion, the FiiO EH11 is the better buy for most people, because it covers more ground: LDAC hi-res audio, dual-device connection, app EQ, a gaming mode, 30 hours of playback and a 92g fit that makes long sessions realistic — plus a full year of warranty. The Yechiry BT 5.4 is the one I would recommend instead if your listening happens while moving: the ear-hook design, water-resistant sealing and charging case are exactly what a runner needs, and the shorter battery and warranty are the price of that focus. Match the product to where you actually listen, and either one will do its job well.
FAQ
On paper, yes for supported sources. The EH11 streams LDAC at up to 990kbps with a 40mm driver extending to 17Hz. The Yechiry uses a 13mm driver over standard Bluetooth 5.4 audio. If your phone supports LDAC, the EH11 has the higher ceiling.
The FiiO EH11 claims up to 30 hours of playback from a 1.5-hour charge. The Yechiry BT 5.4 gives 5–6 hours per charge in the earbuds, with the charging case adding top-ups between sessions.
The Yechiry BT 5.4, clearly. Ear-hook earbuds stay put during movement, the coating handles sweat, and the case keeps them stored and charged. The EH11 is an on-ear headphone with no water rating — better suited to a desk, a sofa or a commute.
