With the K845, AKG utilized many materials to design the headphones.  The use of metal for bits and pieces of the frame give the headphone a nice contrast.  The mixture of both brushed aluminum for the headband and sandblasted metal for the arms gives the K845 BT a very unique look.  The round housings are flatter since the end cap is glossed over and almost glass-like.  In the center of the end cap is the AKG name in a reflective, mirror-like finish.  The headphone aesthetics are really top notch.


Design: ★★★★


In the past few years, Harman has been hard at work in their quest to determine what sound signature people preferred on a pair of headphones.  Their results showed a small bump in the sub and low bass regions with slightly relaxed treble.  Well, in many ways, the AKG K845 BT utilizes these findings as that is just about how they sound.  They are relatively linear with a slight warm tilt and tuned beautifully.

In the low-end of the spectrum, the bass proves itself with enough quantity to allow more than enough presence from the lower-bass up through the mid-bass.  The sub-bass offers a very subtle fluidity to its texturing as it’s more solid overall.  Going up a little further, the low-bass offers a well-defined impact and slam that is a little larger in size.  That said, the mid-bass is not the tightest I’ve heard, but it’s still well controlled in its own right.

Walking up into the midrange, we find a very musical, emotional midrange that is warm and inviting; never offensive.  Detailing is pretty good for this sort of signature while the retrieval of said detail is quite effortless.  The upper midrange instrumentals offer good clarity, but is never in your face (due to the overall warm signature).  Vocals are really brilliantly tuned by AKG as they have great range and dynamics.

As we go up into the treble regions, we find that this is where the headphones get the majority of their energy and brightness.  The upper treble is probably my favorite portion of the highs.  They are detailed abundantly with clarity and separation in the most delicate manner.  They can, however, be a little thin at times.  The lower treble offers good detailing and presence overall with OK extension.  Snares snap energetically, like this should.

Audio: ★★★★½


AKG doesn’t include any sort of carrying case with the K845 BT unfortunately.  With a pair of headphones that costs around 300 dollars, I would expect some sort of carrying case.  Fortunately, the headphones seem like they should be able to take quite a beating and still walk it off.

The housings used on the K845 utilize plastics.  The plastic is actually textured delicately and feels firm to the touch.  In other words, it doesn’t feel cheap or weak.  Instead, the plastics used on these AKGs are strong and robust.  The arms that connect to the housings use sandblasted metal.  The moving hinges and arms are stiff enough so they don’t move freely, but also loose enough to be adjusted quickly and painlessly.


Linking the arms on either side, the headband itself consist of two thin aluminum strips, one of which is wide, that are each less than a millimeter thick.  This structure allows the headband to be quite malleable, but also resilient at the same time.


Build: ★★★★


Despite how large the K845 BT physically is, they are surprisingly very lightweight due to the materials AKG uses, mainly plastic and aluminum.  Soft, supple memory foam wrapped around a leather skin rests gently around your ears.  These two properties allow the headphones to be worn during long listen sessions without causing any discomfort whatsoever.  There is, however, one caveat, if the AKG K845 is left resting around your neck, they may latch onto your hair which can be a little discomforting.


Comfort: ★★★★½


The AKG K845 BT, and it’s wired brother the K545, retail for around 300 and 250 dollars respectively.  The sonic abilities they offer at this price is pretty staggering as they can easily compete with the likes of the NAD VISO HP50, V-Moda M-100, and Bowers & Wilkins P7, each of which are priced similarly, or more expensive.  The build and design is really top notch, as is the comfort.  From that viewpoint, these definitely are well worth the money.  The battery in them should last you a week with constant use (normally a couple days more).

There is one caveat though, the controls, which are conveniently placed on the housings, are quite limited.  They can only answer calls, hang up calls, play, pause, and adjust internal volume.  There is no way to call Siri or skip tracks, both of which would be good features to have.


Value: ★★★★½

Final Thoughts

If you’re one that can deal with the limited controls that are offered on the BT headphones, the AKG K845 BT are an absolute steal for a pair of wireless headphones.  They offer sound quality that is impressive, wired or wireless, and a professional design that is also fun and elegant.

I’d like to thank Derrick for the product sample.
