i was wondering what should i expect from dual balanced armatures?

Firstly, congrats for getting the excellent sounded TDK BA200 which totally different sonic signature from your BTP. You'll need burn-in time both for this great IEM and of coz your ears. Comparing open and full enclosed can earphone/headphone are between dynamic and articulate sound.
Open can disphragm based IEM normally associate with,
1. More dynamic and punchy bass given the ability of the diaphragm travel length and speed.
2. Lively, airiness treble that overpowering the midrange. As a result it may be sounded more pleasing but at the same time more fatigue to hearing system.
There's another 2 problems,
A. Cause disturbance to yourself as the open can design have nothing preventing outside noise intruding into your music.
B. Cause disturbance to people next to you, especially if you blast your music at extreme loud level. So it's best to use at somewhere with no people around.
Full enclosed can BA IEM normally ,
1. Solved A and B problems. No more sound leak in & out. No more disturbance to yourself and others.
2. More clean & articulate bass aka less dynamic and punchy. Most BA tend to be with light articulate bass. This is due to there's no diaphragm travel involve thus there's nothing to push the air volume inside or pump in air into the can. Think it's because of this, BA IEM are normally closed can design?
3. More articulate & airy sounded mid and treble. The mid also tend to be more forward aka warm/sweet like what a tube amp sounded.
4. The strongest point of BA IEM (at least dual BA) are the much better Sound Staging than diaphragm base IEM. It is by far the most brilliant parts of a (dual) BA designed IEM.
Above just my own thinking based on my 1st BA IEM the TDK BA200. Of course it is not my first audition to a BA. Me too with articulate and less punchy bass of a BA IEM, I has been hesitating to join BA circle for years. There's mainly because I would not pay a premium on a tiny IEM. I've rather spend a bigger fortune on a good stereo system setup at home.
But on April this year, the TDK BA200 has totally changed my mindset. No only it has excellent mid, treble. The well weighted and articulate bass it produces also has better punch than most dual BA IEM around. Given it tiny price below $200, $130 (both brand new price) to be exact for my BA200, TDK BA200 was a real star for dual BA IEM standard.
