EarFun FREE – Review


EarFun Free

| True Wireless | 6mm Graphene Driver | IPX7 |

🎧 We are reviewing the EarFun Free, a true wireless earphone with friendly price.

The EarFun Free features a 6mm graphene driver per side and a IPX7 waterproof rating that allows it to withstand up to 30 minutes under 1 meter of water.

The back plate of the earpieces is touch sensitive, enabling to control the main music playback and call commands by simple touch “tapping”.

Inside each housing, the unit hold a 50mAh battery that the brand says that can provide up to 6 hours of music playback. Additionally, the battery pack/charging case can recharge the units on-the-go, giving 4 full charges – which should total approx. 24 hours of combined battery life.

The EarFun Free is the first and only true wireless from the brand to date and is available either in white or black color.

EarFun Free Review

Tests & Scores


Accessories & Packaging

The EarFun Free comes with 3 pair of eartips, a charging cable and the battery pack – quite a standard for most TWS earphones on the market.

The unit comes inside a clean looking packaging with a white and yellow box.

Bass & Sub Bass

Bass on the EarFun Free can reach and handle deep sub-bass without sounding over-boosted nor drowning their sound signature.

Their mid-bass is well-controlled with a fun and punchy sound that can make them capable of covering most music genres, sounding energetic but at the same time not becoming boomy.

In general, the brand did a very good job tuning the lower end on the EarFun Free – yet, it is important to highlight that this kind of bass tuning will not be the best choice for electronic or EDM listeners.

An EQ can be applied to boost their bass personality adding a much more intense punch and allowing their sub-bass to get even deeper.

Mids & Vocals

The midrange on the EarFun exhibits a warm and full sounding tuning with a more emphasized upper mid end than on their lower midrange.

Nonetheless, their midrange does not suffer from excessive mid-bass bleed – in fact, we would say that their male vocals and lower midrange are substantially clean for a warm sounding earphone.

The result of their midrange tuning is cozy, yet being able to offer crisp upper mids and female vocals.

With an EQ, their midrange can be pushed for a cleaner lower midrange, keeping their warmth and not introducing too much harshness.




Highs & Treble

Highs on the EarFun Free are fairly detailed for most listening sessions and can provide a pleasing balance of brightness-smoothness, which results in a gentle sound but that does not becomes neither excessively bright nor overly rolled-off.

Piercing and sibilant peaks are rarely perceived, with sporadic sibilance within a range of mild intensity.

All in all, the EarFun Free sound extremely similar to the Xiaomi Redmi Airdots. In fact, our measurements revealed that both have almost identical frequency response curves.




Sound Leak

The sound leaking out of the EarFun is remarkably low and nearly inaudible when listening to music at nearly any volume setting.

This makes it a wise match for users who need to use them in libraries or who are concerned about the privacy of their music listening sessions.

Sound Isolation

Differently to it’s leaking performance, their isolation is not as strong as on some of the most efficient isolating earphones that we have tested so far.

This will make them hard to provide absolute isolation but will enable them to grant partial awareness of the environment – feature that is usually desired by people practicing sports outdoor.

The larger and more protruding footprint of their earpieces might be less comfortable for smaller than average ears. Despite this, most of our editors found zero discomfort issues nor felt them uncomfortable at all.

Their larger size will enable an easier surface area to be grabbed and handled, once placed in the ears. In addition to this, the form factor of the units are curvy with rounded edges, avoiding sharp ends that could cause pain.

Response to Equalization

This EarFun TWS showed efficient response to EQ with substantial fine tuning potential but without a groundbreaking signature modification.
