Blitzwolf TWS earphones: FYE3 vs FYE7

Blitzwolf  sells many different gadgets and i don't know how good are their vacuum cleaners and IP cameras, but their wireless earphones definitely deserve a closer look.

The colourful BW-FYE3 and BW-FYE3S look cool, are touch sensitive and have a storage box that can also be used as a power bank.

The BW-FYE7 may look austere in comparison, but it hides a killer feature in its apparent simplicity.

Which one would you choose?

Blitzwolf BW-FYE3 and BW-FYE3S are 2 versions of the same earphone, differing only by their  charging box.
The "S" version has a cool integrated digital power display, and is not necessarily more expensive if you know where to look.

In both models, the charging box contains an integrated 2600mAh battery that can fully recharge the earphones about 3 times or give an extra 30% of battery life to most smart phones.

The whole thing weights about 100gr and still fits in most pockets.

Pairing and usage couldn't be simpler thanks to True Wireless Stereo technology (and BT 5.0):
The ear buds power on instantly when you pick them out of the box, then connect to any previously paired device or go into pairing mode if no known device is found in range.

One press on the touch-sensitive surface will pause, twice, it brings your Google Assistant/Siri/Cortana. A long touch turns them off.

Of course you can choose to use only one (more convenient for phone calls).
With this particular model, your "master" unit (aka "TWS master") is the Left bud (BW-FYE3S L).

Only this one needs to be paired and the right one will depend on it to function. So whenever you only need one ear bud, the one to return to the box is the Right one (the "slave").

I only mention this because the next model reviewed here (FYE7) has a different chipset and works the exact opposite way.

Stereo sound quality is good, with decent range in trebles and bass, definitely a world of difference with the cheap Ipipoo IL93BL I bought some time ago.

I tried the microphone in a phone call and it provided a good sound quality to the other party. Something that is not often the case in that price range.

Fitting:
The buds come with replacement silicon earpads in 3 different sizes.
Once in place they sit tight, but fitting them into the correct position does not always come naturally... at least for me.

Buying options

The price is roughly the same for both models, so there's no reason not to pick the FYE3S. Also, it's not necessarily more expensive from the USA or UK warehouses, although the shipping cost might add up a bit.

So pay attention when choosing the warehouse (CN, USA, UK) and the product type on Banggood.com so you get the best price and the right version.

Heavy bass is not an over-statement

The FYE7 is the top of the Blitzwolf range of earphones.

Aside from being TWS (True Wireless Stereo), its outstanding feature is really the Dual Dynamic Drivers, hence the "Heavy Bass" in the product description.

Each earpiece contains two separate speakers, one to handle the high and mid frequencies, and one to handle the bass.

Due to this characteristic, the earphone tends to have bigger dimensions than average, but... what a difference! The bass is really more punchy without hindering the sound clarity.
I had to hear it for myself to realise it's not just another commercial gimmick!

The storage box can charge the earbuds fully fully about 3 to 4 times. It weights 66 grams with the buds parked inside and a magnet keep the lid closed. A button at the back, next to USB charging port, will turn on the front LED to indicate the battery level of the charging box.

Pairing and usage: 
Here, it's the right bud, BW-FYE7 R that should be paired as the main unit (TWS master).
It's the one that will keeps working if you return the other in the box.

BW-FYE3(S) or BW-FYE7 ?

Both models are sold at the same price (~35€/40$), have a high quality feel but offer different qualities.

The FYE3 is more a general purpose set for everyday, with a well balanced sound, standing out by its beautiful design and its 2600mAh emergency charger could prove a life-saver in many occasions.














The FYE7 counts on its Dual Dynamic Drivers to make the difference, and it does! It could be packaged in a plastic bag and would still be a bestseller!

Who needs to add any cute colour effects, extra charging feature or touch sensors when the sound speaks for itself!

The true separation between bass and the rest really makes a huge difference and you would go for this one if you like rich and deep sound in music or movies!

Update November 2019: While I still prefer the FYE7 for its sound quality, it has an annoying problem: The earphones keep draining the box battery even when not used, so the whole thing will be empty flat after about 2 weeks, probably when you really need them here and now...
The FYE3 does not show this problem and that's the one I always keep in my jacket despite the bulkier case.
