I think you are right and they were definitely talking about the Sabre. That is why I became interested in the Delta's (the ability to modify more than just the bass), but I ended up going for the Vyrus (that will have the same filters, although I understand that they are not at the same level) and also the Bluetooth lanyard (that will work for both the Sabre and Vyrus).
Well, after about a week of listening to my replacement Sabre I am going back and forth between the gold, red, and orange filters. I find the changes to be very subtle and focused on the lower regions (bass). I don't think I'll have much use for the gunmetal or purple but I'll give them a listen eventually.
I know and is something prevalent at headfi. Mine was a genuine question, mostly out of curiosity, that got answered and we moved on. The other poster response was inappropriate, almost suggesting that I wanted a product for free. Anyways, I'll move on because I already got my answer and I don't want to derail the topic.
I already have the Sabre and decided to get the Vyrus because of the Bluetooth lanyard option. I was interested in the Delta as well but I think I will be happy with the Sabre and Vyrus and the Bluetooth option.
I was interested in getting the Vyrus with the exchange rate going on now and the store discount, but after having the Sabre for a week I have become interested in the Deltas. I know that the Deltas and the Vyrus are not on the same level, but I am wondering if it would be worth it to purchase them if I already have the Sabres? Do they offer something different?
