Another winter’s day here at the MajorHiFi review headquarters. My desk swamped with headphones and the various eggnogs I’ve been testing, today I’m taking on the BLZK Sky Free. Retailing for an economic $49, this true wireless earphone offers an enticing proposition. But how does it sound? And is it worth the price?
BLZK Sky Free True Wireless Review
The BLZK Sky Free arrives in a very cheap white cardboard box that holds the earphones, a charging case, four pairs of eartips, and a micro-USB charging cable.
Holding the earpieces in my hand, I am slightly put off by the size, however, they still fit in my ears with ease. A touch sensor on either earpiece allows for controlling playback, volume, and accepting or rejecting phone calls. While the controls feel responsive enough, it does seem a little too easy to accidentally pause or play music when trying to remove the earphones from my ears.
Both earpieces are color coded, though a bit oddly. In Headphone World, most brands code the earpieces or cable termination for easy identification. Red is right, blue is left. However, the Sky Free switches this around, so the right earpiece features a blue circle. The left side sports a red one. I can’t explain why, but this really, REALLY aggravates me.
Running on Bluetooth 5.0, the connection quality on the Sky Free is fairly solid. During my street tests, I only had one drop out. This earphone supports HFP, HSP, A2DP, and AVRCP codecs.
Battery life measures a fairly standard 4-5 hours at 70-80% volume, with an additional 90 hours available through the charging case.
When it comes to the charging case, the BLZK Sky Free offers a couple of nifty features. In addition to a battery life/recharging meter, the case also features a USB port. This allows the charging case to double as a 4000 mAh power bank.
However, these extra features add a bit of extra girth to the case, making it not-so-pocket-friendly.
Call quality comes across as decent, though like other earphones with a similar design, talking while using the Sky Free requires me to project my voice a little bit more.
Isolation is also fairly solid, probably owing to the bulk of the earpieces. As a result, I find myself actually having to take them out when talking to people (as opposed to just pausing the music). However, the upshot of this is that the earphones do a solid job of blocking out unwanted noise.
The BLZK Sky Free offers a fairly bumping low end. There’s detail here, though less than some other true wireless earphones at this price. Instead, the show-stealer here comes in the form of large, powerful bass. This gives the Sky Free a fairly heavy-handed low end, but one that sounds fairly impressive with rock, hip hop, and some electronica. However, these lows may still sound a little sloppy and uncontrolled on some tracks, so this bassy sound definitely won’t be for everyone.
There’s more detail present in the mids than in the lows, it seems. As a result, the Sky Free feels marginally better in this part of the frequency range. Though there’s more fidelity in the sound of vocals and instrumentation, this earphone still exhibits some compression. While not too noticeable on some pop and electronic tracks, it feels jarringly present on well recorded rock tracks.
In the high end, the BLZK Sky Free offers a fairly accurate sound. Not too bright or shrill, the highs feel just the slightest bit relaxed. Unfortunately, detail can seem rather hit-or-miss, working well with more compressed pop tracks but missing the mark when it comes to some high-res recordings. I wouldn’t recommend this earphone for classical or jazz as a result, but the highs still aren’t a total misfire.
The Sky Free actually sports decent soundstage for what it is – a sub-$50 true wireless earphone. While there’s some overlap and confusion between some instruments and vocal sources, there’s still enough depth here to keep simpler tracks relatively clear. As a result, this earphone may not sound the best with classical tunes or more complicated tracks. But for a $50 true wireless option, this soundstage does do justice to simpler recordings.
Pros and Cons
Pros: The BLZK Free Sky delivers passable audio quality and a decent fit. For simple, compressed audio, this earphone isn’t a bad option. Call quality doesn’t seem too terrible either, and battery life sits right around the industry standard.
Cons: Sound quality here could be better for more genres, and the charging case lands a bit on the larger side. But the color coded circles sitting on the wrong sides has to be the icing on the Con Cake.
Normally, when a true wireless earphone aims for the $50 price point, it usually sacrifices a lot of sound quality in the process. But the BLZK Sky Free can actually dish out some decent audio – provided, of course, that you don’t set the bar too high. Indeed, most of my misgivings have more to do with the cosmetics or presentation of this earphone. With that being said, would I still recommend this earphone at the $49 price point? Yes, but only for folks who don’t want better audio quality at the same price.
Also at $49, my new favorite true wireless earphone, the Strauss and Wagner SW-TW401, might offer better sound quality for nearly every genre. Still, the battery life on this earphone might come in just a smidgen below that of the Sky Free.
