Pros: Very addictive sound, mid forward, bass recessed but has excellent extention, easy to disassemble
Cons: Highs don't impress, but don't get in the way, light on bass quantity, doesn't respond to EQ
What a great headphone! Disclaimer: at my house to get any head time at all, you've got to match up with the Sennheiser HD800, PSB M4U 1, Klipsch Status, HiFiMan RE-262, and others. In short, the Koss Tony Bennet is the over-ear equivalent of the RE262; both are mid-forward with deceptively strong bass and calm highs.
I don't find them to be excessively bass light, thanks to a very deep extention.Bass is typically low in volume and high in quality. But give them a bassy DAC like the Geek Out V2+, and they positively slam! Compare to the M4U/Mojo combo perhaps.
Note on bass: I don't reccomend trying to increase the bottom end with the EQ. You'll get your little bit of extra bass all right, but at the cost of some of the quality in the mids, which is where its at in these headphones. If you want more bass put on a different headphone, or a bassier DAC.
Soundstage is adequate. I think i hear soundstage differently than most, so YMMV.
As Tyll says, they are well built and easy to mod. Even though the cable is removable already, I immediately converted mine to dual mono entry, for easy use with both SE & balanced DAC/amps.
Great for all genres; better for EDM than you might think. They make it easier to understand hip hop vocalists. They scale well, sounding good off an iPod Nano 2gen, & sounding even better with better signals, all the way up to powerful balanced amps.
They'll never compete with the HD800 in clarity or technical anything, but they have a smooth, relaxed sound that's plain addicting. A real go-to pair any time I don't want or need mass quantities of bass, but still want to hear all of it, and the simple, elegant style works perfectly for the image i usually go for. For me, for the price, 5 stars easy.
I've long understood the value,of tiprolling IEMs, but swapping different pads onto and off the TBSE1 was a revelation to me. For example, while the velour/memoryfoam pads are the most comfortable I've used (and the warmest on cold winter nights), i think I like the sound better with stock earpads off an ATH-M50. With the M50 pads, the bass is much stronger and punchier, resulting in a much more balanced sound overall. In fact, I have trouble telling the difference between these and the M50 now! One identifying factor is that while the M50 still emphasizes bass a bit more, the TBSE1 actually reaches lower down the scale than the M50 can!
Buying the Koss TBSE1 (or the DJ100 it's based on, presumably) nominally gets you two very different headphones.One with that relaxing mid-centric sound, the other an M50 clone with notably better bass, but with dryer, less exciting treble. I'm going to leave the M50 pads here for awhile. Meanwhile, the velour memory foams don't take nearly so much bass away from the M50 while expanding the soundstage by a factor of 3 or 4. It comes with the price of greatly reduced isolation, but that's a topic for a different review.
