FiiO EH11 Review – Headfonia

Today we review the FiiO EH11, a retro-inspired Bluetooth on-ear headphone from FiiO. Priced at just $29.99 USD.

About FiiO

Founded in 2007, FiiO has grown into one of the most recognized names in the portable audiophile space, standing alongside brands like Astell&Kern, iBasso, Meze, or HiBy. From IEMs to headphone amps, DACs, and of course DAPs, the brand has consistently delivered an impressive roster of award-winning devices like the S15, BTR17, K17, or M15S.

And if the journey started out in the Chi-Fi bracket, offering affordable yet surprisingly solid gear, FiiO steadily climbed the ladder over the years. So much that it’d be hard to call them anything but Hi-Fi nowadays, with their M27 setting a new benchmark for what a portable flagship could achieve, the M33 R2R bringing resistor-ladder technology to the portable world, and a whole new range of headphones expanding the brand’s footprint well beyond DAPs and IEMs.

That range now includes models like the FT1 and its planar sibling, the FT1 Pro, all the way up to the flagship JT7. And just when I thought the lineup was complete, FiiO surprised everyone with something completely unexpected: the EH11, a tiny, retro-styled, Bluetooth on-ear headphone priced at less than thirty bucks – right between the Anytime and the just announced EH13.

Let’s find out what the FiiO EH11 is all about.

FiiO EH11

Design

“Expressing the retro-futurism aesthetic”, the FiiO EH11 completely embraced the 80’s look from top to bottom.

Compact wooden earcups, a transparent plastic headband revealing the inner mechanism, big orange/black foam pads, and a silhouette that screams Walkman-era portable headphones. A look clearly inspired by those old-school headset, following the new trend of vintage-looking products like turntables, amplifiers or even… cassette players (check the CP13).

Now, am I personally a fan of the retro look? Not really. I tend to prefer cleaner, more modern designs – the kind of restrained industrial aesthetic you’d find on Shanling or Astell&Kern. That said, I have to admit there’s something genuinely charming about the EH11’s aesthetics: retro is making a comeback – you see it everywhere, from fashion to consumer electronics – and FiiO timed this one just right.

FiiO even went as far as offering five different colors: transparent black (the one I got), transparent, off-white, burgundy, and cyan, each paired with matching foam earpads. A fun touch that lets you customize the look, and I wouldn’t be surprised if hipsters and younger users buy two, just to mix and match.

Definitely the kind of product that would look perfectly with the FiiO Snowksy, or the new Disc – which is entirely intentional.

Build Quality

At 92 grams and a clamping force of just 1.7N, the EH11 is featherlight. You could forget you’re wearing them – and I did, more than once.

But, let’s be honest here: this is a $30 headphone, and it feels like one in terms of materials. The plastic is thin, the headband adjustment mechanism, even if quite clever feels a tad flimsy, and compared to the JD7 and JT3 I reviewed a while ago, you’ll immediately feel the seventy bucks difference.

That said expecting premium build quality from a sub-$30 Bluetooth headphone would be absurd and, for that price, everything still clicks into place – up to a certain level: wooden faceplates feel surprisingly solid to rotate, and nothing creaks or rattles when you move your head. A perfectly adequate headset. Not flawless. Adequate. And that’s fine.

Layout

Clean and simple, the FiiO EH11 keeps most of the controls hidden:

• two wooden rotary knobs, controlling volume (left) and track skip (right)
• a tiny multi-function button for power, pairing, play/pause, and voice assistant
• a built-in microphone for calls

At the bottom of one earcup:

And… that’s it! No 3.5mm jack, no wired option, no ANC. Pure wireless simplicity. Some might miss the auxiliary input for wired listening, but again – thirty dollars.

Sound

For this review, my main sources were: iPhone 13 Pro Max / iPhone 17 Pro Max / FiiO M33 R2R / FiiO M21, trusted sources that I used extensively for the past months. The FiiO Control app was also tested via both DAPs (iPhone doesn’t support LDAC)

Files were played from either Apple Music (Hi-Res when available) / Spotify or my own music library. Some tracks will be highlighted, just so you can try them at home too!

Overall signature

So, how does the FiiO EH11 actually sound? In a word: disarming.

I’ll be upfront – I did not expect this. When FiiO told me they were sending a $30 Bluetooth on-ear headphone, I braced myself for something functional at best, forgettable at worst. The kind of product you test in an afternoon, write a polite paragraph about, and move on – sorry for you Anytime ANC… That’s not what happened.

The EH11 delivered a warm, full-bodied, and genuinely musical presentation that caught me completely off guard. There’s a richness to the midrange and a weight to the low end that I simply haven’t heard from an on-ear Bluetooth headphone in this price bracket – or even two or three brackets above. The 40mm long-throw driver paired with the semi-open acoustic design produced a sound that felt cohesive, engaging, and surprisingly refined for a wireless headphone running on an all-in-one Bluetooth SoC.

Is it perfect? Of course not. The treble rolls off a bit early, lacking the last bit of air and sparkle that you’d get from a proper open-back like the FT1 Pro. Sub-bass, while present, is more suggested than physically felt – a natural limitation of the on-ear, semi-open design that simply can’t build the same air pressure as an over-ear. And positioning matters: shift the pads slightly on your ear and the tonal balance changes noticeably. That’s the nature of on-ears, and no amount of engineering can fully solve it, yet.

But here’s the thing – none of that matters in context. At this price point, you’re not comparing the EH11 to an Audeze LCD-X or even a Meze 99 Classics V2. You’re comparing it to whatever random Bluetooth headphone you’d grab off a shelf. And against that crowd, the FiiO EH11 is playing an entirely different game.

Head to head with the Koss Porta Pro Wireless – a model that has long been the de facto recommendation for budget Bluetooth on-ears – the EH11 genuinely came out on top. Better midrange clarity, more controlled bass, and a wider, more open presentation thanks to the semi-open design. A result I wasn’t expecting, and one that solidified my impression: FiiO didn’t phone this one in.

Same goes for the soundstage, a lot wider than expected for a compact on-ear, thanks to the ventilation ports that let air flow naturally in and out. Separation is decent too, instruments never collapsing into each other on busy tracks, and imaging works surprisingly well for the size, with a convincing left-right spread, delivering enough depth to make well-recorded tracks feel spatial rather than flat.

Interestingly, pairing the EH11 via LDAC with the M21 or M33 R2R tightened up the presentation even more, compared to my iPhones. Nothing game changing, but better transient definition, cleaner edges on vocals, and a bit more grip in the bass, confirming what I suspected: the EH11’s driver is actually capable of more than most sources will extract from it. A sign that FiiO engineered this one with genuine care, not just as a disposable lifestyle accessory.

So yeah, in my opinion, this is without a doubt one of the best sounding Bluetooth on-ear headphone I’ve heard in years, below the $200 USD threshold; above a Sennheiser Accentum, and a few level over the Koss.

A lovely surprise.
