EdifierSTAX SPIRIT S3 Wireless Planar Magnetic Headphones, Bluetooth V5.2 Hi-Fi Foldable Headphone with Hi-Res & Snapdragon Sound with Mic for Audiophiles, Home, Studio

Now I have (and have had) a lot of audiophile headphones. Currently rocking Susvara on my Feliks Envy.These are not even close (lol) but you know what they are absolutely amazing for the price.They are very clear without sibilance. Bass is present and natural. It's absolutely there when it needs to be but these are not Bass monsters no. You can always EQ a bit in if you really want. They are very well tuned. It's a neutral, natural tuning.The main things I love are:-Ridiculous Battery Life. Right out of the box they were still on 100%. I had these on all week at work. They were left on overnight and I wasn't listening all day but still the battery was still going after a week!-Sound quality is excellent as they are planar rather than dynamic-Very very comfortable in terms of clamping force. I wear glasses and clamping force was too much on the PX8s. These are just perfect and very light as well especially for a planar.-Yes there is no ANC but I find that at work fully open back headphones means too much disturbance and full ANC is just too much if I can't hear my phone ring (for example). The simple seal creates just the right amount of ANC for my use case. YES you will hear traffic when out and about but it's not intrusive enough to tear you away from your music.-They come in a very small, smart case so can easil be transported.-Can still be used passively when the battery expires. I have not tested this.A wonderful alternative to the Sony's, Bose, B&Ws and B&Os of this world.Honestly I am very impressed with them and this is from a seasoned audiophile.Give them a try.

Note: all opinions are my own and this item was bought with my own money with zero discounts or influence from any external factors.Tl;dr: These are probably the best you're going to get for their price in terms of raw sound quality, paired with microphones that have no business sounding as good as these do and an 80 hour battery life, but beware they lack most of the "modern" functions of many bluetooth headphones.Summary:The Stax Spirit S3, despite the name carry more similarities to the Audeze Penrose/Mobius and LCD-1s than they do anything remotely related to stax. With that said, it's a clever marketing stunt to slap a random acclaimed headphone brand on your entirely unrelated but intrisically connected company; good job at capturing attention of audio nerds with that, Edifier.Features/Whats missing:As mentioned above, these carry Audeze DNA, making use of what seems to be the same or similar planar magnetic drivers to the open-back LCD-1's, albeit with a much less roomy sound and somehow less bass despite any profiles used.Alongside this, we have an 80 hour battery life (wow) which can charge to 10 hours with only 10 minutes and takes about 1 and a half hours to fully charge (I am yet to even need to charge these). Oh, and physical buttons, something I wish we would have kept given 70% of the time touch controls are a pain to use and being an industry standard doesn't make them any better than buttons, see iPhone missing headphone jacks for reference. The buttons are easy to find, generally very clicky, plasticky covered with rubber, not the best sounding when you depress it as it sounds like a little twang but it's buttons, what do you expect?Edifier has a barely advertised and uncustomisable application which is used to change the tuning between "Classic", "Hifi", and "Stax"; I personally found Classic to be somwhat v shaped harman-esque signature, Hifi to be a little bit more articulated but keeping in line with the harman vibes and Stax to just be very treble oriented and well... Not for me. I stick with Hifi.So what's missing? ANC, Transparency mode, LDAC, customisable EQBuild: It's "okay", alot of people have whined and cried about it not being build excellent but it just feels as "okay" built as a XM4 or the LCD-1's, not amazing but passable once you acknowledge you should be using it to play music instead of using them as earmuffs (shoutout to the idiots complaining about creaks when they're missing when you play music).Sound:They sound like planars.. Wait, let me elaborate; these are very accurate, probably even more accurate than the Focal Celestee's (£999) with good imaging, layering, seperation and as I said, accuracy. They're not super bassy but they slam enough for me with enough subbass and midbass to make me smile when playing songs such as Kazuo's "WATCH OUT!"The mids are nice, they're a good listen for both male and female vocals and place the singer a realistic manner, reverberations in songs such as Brandon's "Elastic" from his voice and guitar play are almost life-like and supremely accurate, similarly Alina Baraz's "My Whole Life" sounds beautiful; the voices of these singers are very intimate but placed far enough for you to not feel as if you're listening to a claustrophobic pair of headphones. If I had to compare I would put them above any closed-backs I have heard in terms of accuracy and placement and the spaciousness, granted they fall flat against even the KSC75 in those respects.Highs:I don't really know what to say about highs, a lot of what I listen to is mid-centrics however instruments such as cymbals along with female vocalists sound rather pleasant, there is enough decay and control to avoid sibilance especially when listening to songs that can sound rather sibilant on other pairs. JYOCHO's "Lucky Mother" is a rather busy track with alot of mixing between a flute, vocals and cymbals and all of which sound defined, proper, and smooth which is nice.Conclusion:They're good, damn good even if you can ignore the lack of features.

This Planar Magnetic headphones would be 5 big but for me they lacking of :- touch more bass- noise cancelling- touch more loudness- EQ option in the app- have touch more clamp forceOtherwise very detail and clean sound,good sound stage.Option of 3 sound presets in the app.Extra cooler pair of ear pads.Amazing battery life.Folding flat and inwards.Good protective case - but I have bought cheap case from Amazon that is even smaller and they fit perfectly without taking as much space as the original case.Woul I recommend this Edifier Stax cans? Yes they are great,sound great and dispate lacking futures I keep them.Price is bit too high in my opinion,but maybe this is caused by planar magnetic drivers technology being more expensive to produce than dynamic standard drivers I like to be aware of my surrundings therefore I don't really need NC but for most this might be as must future.I have tried other headphones before like Bower and wilkins Px 7s2,Yamaha,B&O etc and out of all I have tested this Edifier cans don't make my ears very hot as others did and I can wear them for few hours with no problem.If this would cost around 150£ I would highly recommend them,otherwise I'll say buy it - try it - decide by your self - keep it or returning.Choice is wide these days.
