I'm an enthusiastic headphone user and have been for many years. To give you an idea of the kind of sound signature I like, here's a list of some of the headphones I have (or have had in the past):-
Ultimate Ears Triple Fi10
Sony WH1000XM2
Shure E500
Apple Airpods
Etymotic ER4P
SoundPEATS Q32 True Wireless
Mavin Air-X True Wireless
Sony MDR-888 earbuds
Apple iPod 5th gen
Apple iPod Nano
Creative Nomad Jukebox 3 (perhaps the best sounding MP3 player ever!)
Samsung Galaxy Note 2
LG V20 (My current player)
Whilst both the headphones and players listed above may vary somewhat in both their basic sound quality and sound signature, it's fair to say that they're all pretty damned good. My current player is the rather excellent LG V20 which features an excellent DAC/Headphone Amp section, this is mostly wasted when using bluetooth headphones. However, the player does support all the relevant high-res codecs including AAC, APTX, APTX-HD and LDAC - so makes an excellent bluetooth player as well.
Finally, as part of my intro, my musical tastes include Rock, Classical, Acoustic Folk, Trance and EDM. I tend to usually listen to music fairly loud but also appreciate headphones which can play at lower volumes (for bedtime use) and so appreciate IEM's that tend to not leak sound out.
The BT Transfer's come supplied in a rather nice retail package which consists of the usual fare - headphones, replacement tips in various sizes, instruction manuals and a USB type B charge cable. The tips include 'wings' which definitely help you get the best kind of seal as these headphones do have a fairly shallow fit and it's definitely worth trying them all out until you find the ideal fit.
The headphones themselves are gunmetal grey METAL! There's something very reassuring about metal headphones - you really feel that these are designed to be used and abused somewhat. They are lightly magnetised so you can keep them around your neck and put them together when not in use. There's a 3-button control on the right which offers track skip, volume adjustment and access to Siri/Google Assistant. The remote buttons are actually easy to find by feel and they have a nice positive click to them. There's a microphone for phone calls and people (my daughter) reports that I sound perfectly fine. Callers voice comes through both headphones which is always nice to see. As with most bluetooth earbuds, the Transfer's come supplied with an assortment of different sized tips and wings and I wouldn't think you would have any problems finding the right fit. The Transfers also come with a quite nice hard case, a short USB change cable and some printed instructions.
The wings and tips actually click into place - this is great as they feel far more secure than with other in ear monitors I've used. The sound tube has a fairly large bore to it and the supplied tips offer a fairly shallow fit in the ear. Luckily the wings definitely help hold them in place. The end result is that I get a really nice seal - albeit shallow when compared to IEM's like the Triple Fi 10's, Shure E500's and Etymotic ER4P. Unfortunately for me this also means that the isolation from the outside world isn't as effective as the others mentioned - in all fairness though, your results could easily differ from mine. What I will say though is that they are supremely comfortable, feel very secure and offer a really nice consistent sound without you having to 'fiddle' around with them (like you have to with the other IEM's mentioned).
The Status BT Transfer are fairly long - they will stick out of your ear and make you look like Frankenstein's ugly half cousin. Luckily I don't give a rat's fart to how I look when wearing headphones - let's face it, I'm quite comfortable wearing Airpods in public. I haven't tried wearing these in bed - that's also Airpod territory. I suspect a small part of my brain could leak out of my other ear if I lay on my side with these in;-)
Connection with my LG V20 is excellent - very stable (absolutely no dropouts), very fast connection and automatically uses the APtX codec (which a couple of my other wireless APtX headphones don't do - I have to change from AAC to APtX manually using the Developers Options settings function on the phone). Range isn't too much of a problem - not perhaps the best in my collection but certainly good enough pass the upstairs bathroom challenge. Certainly if you're walking around with your phone in any pocket you shouldn't experience any problems. In fact, I find that if you pair your Bluetooth headphones to your phone and then power off the phone completely and re-boot, the bluetooth connection appears to be a lot more solid.
I feel it's only fair that I should point out a few of my home truths:-
I'm 56 years old. Much as I would like to think I've got the hearing of an 18-year old, I know that's very unlikely.
I honestly think that personal audio has got so good now - especially when you compare what we have now to the cassette-based 'Walkmans' of yesteryear. Even the most humble of headphones can sound considerably better than what we used to have. The sound quality gap between a good pair of 20 quid headphones and, say 200 quid headphones is not a massive chasm anymore. There's definitely a law of diminishing returns in play here.
Whilst I can tell the difference between a lossless recording and an MP3 recording, I certainly don't obsess about it - I know some do. 320k MP3's are good enough for me most of the time.
I often fall asleep whilst listening to music - this is perhaps why I'm always more familiar with the first four tracks of most recordings I have;-)
I feel that sometimes sound quality is virtually impossible to put into words - certainly without some sort of point of reference. With this in mind I think my ideal sound signature for IEM's are the Ultimate Ears Triple Fi 10. Whilst perhaps not quite the flattest headphones out there, they are certainly close. In my opinion, any headphone that can be positively compared to the Triple Fi's should definitely be taken seriously!
The Status Transfer are definitely rather special. Taking advantage of the APtX bluetooth audio codec and having decent enough drivers to actually help make a difference, the Transfers offer a really nice detailed and yet mellow sound. The extremely shallow fit isn't a problem for me thanks to the combination of large eartips and the wings which help keep them secure when walking around.
Bass is deep, controlled and doesn't bleed into the mids. It's quite refreshing to have bass like this without having to show them super deep into your ears - the only other headphones I have which can do this are the 1More Triple Driver IEM's and them tend to produce too much bass - wayyyyyyyy to much.
The Magaosi is a triple driver hybrid - two balanced armatures and a bass unit. Both the bass and treble are sharper and slightly more detailed on the K3's. The fit on the K3's is better for laying on your side and the K3's have the advantage of being used Wired as well as Wirelessly. Note that unlike the Status Transfers, the KZ cable defaults to AAC connection every time on my phone and I have to change it manually in the Developers Options settings screen.
OK - these aren't wireless by default. The 1More's have more of everything - deeper bass, higher treble and very hard hitting. Whilst I think the 1More's offer excellent value to money, I honestly prefer the sound and convenience (and fit) of the Transfers. Note the 1More's are more expensive at full retail (although price cuts can bring them fairly close in cost).
Like the KZ Bluetooth Cable, the Mavin's tend to default to AAC on my phone and I have to change them manually to use APtX. The Mavin's are a truly excellent IEM and do have a slight edge over the Transfers. In fact, I honestly think the Mavin's beat just about everything except the Ultimate Ears Triple Fi 10's. In all fairness though, the Mavin's do cost about twice as much as the Transfers - so the comparison isn't perhaps the fairest.
The Mids on the Transfers are very slightly recessed. The lack of bleed from the bass drivers certainly help the mids to come through a little more clearly than what you get from other IEM's at this price point. Instruments and vocals stand out in their own soundstage - which isn't particularly wide but this really isn't I look for too much in headphones - especially in ear monitors.
Treble is slightly recessed in my opinion. Please bear in mind the points I raised above - specifically regarding my age - younger people could quite possibly find these bright - for me, they're just about right.
Whilst there is some audible noise floor from the bluetooth electronics, it's certainly not noticeable once the music starts - even at lower volume levels. The Status Transfers go nice and loud - more than enough to cause long term hearing loss if that's your thing. Like most bluetooth headphones, the individual volume steps are fairly course but when used in conjunction with your phone's volume controls, you should always be able to find a happy medium. Connection with your phone is nice and fast thanks to the use of Bluetooth 5.0 and I haven't experienced any dropouts at all during normal use.
I consider the sound quality of Status Transfer comparable to the likes of the Mavin Air-X, Ultimate Ears Triple Fi 10's and Magaosi K3 Pro's - all of which cost considerably more than the Status Transfers - that's pretty high praise in my opinion.
Excellent fit. Excellent sound quality. Goes loud. Battery life appears to be pretty good so far. Nice range of tips and wings. Steel construction. Comfortable. Fast connection. Can play with the big boys
Slight noise floor (definitely nitpicking here). Would be really nice if they were truly wireless. No active noise cancelling (don't care). Very slightly soft treble.
For their price, they're truly remarkable. If you're in the market for this type of bluetooth in ear monitor, get them! I know you won't be sorry.
