I bought the non SE where the only difference is the colour and case so functionally the same. After about a year with them I am very happy with the BBPro2 and would thoroughly recommend them unless noise cancelling is the primary feature you're after. What I like;
- Very comfortable for long stretches of wear and feel sturdy. I've not noticed anything to give me concern about quality. They are closed so of course ears get warm and sweaty if exercising.
- Battery life is great, especially if you can use the wear sensing feature that automatically disconnects when you take them off.
- Microphone voice pickup and isolation is excellent (as expected from Plantronics) and phone conversations are a breeze – just takes some time to get used to.
- Audio quality for music listening is great for the price. I know there's going to be better if you spend more but for this price range they are very good.
- Bluetooth range and quality seems good but I'm not listening to lossless music so…
My only gripes;
- On-ear sensing doesn't always work for me as I have small ears. This can lead to situations of the headphones cutting in & out as they disconnect and reconnect. Likewise, if you wear a beanie over your head and ears that will stop the feature working. I've had to disable the feature and that really hurts battery life if I forget to turn them off.
- ANC is nothing like what you get from a pair of BOSE QC35 (my only other quality reference) as the noise cancelling on those is staggering. My $80 pair of wired Sony MDRZX110NC on ear phones are about equal to the BBPro2. Without anything playing, with noise cancelling on I can still have a conversation with people and hear some ambient office noise. On a long distance flight they are helpful but if that's what you're buying ANC for I'd look elsewhere.
