Hi Tony,
To give you a view of whether you need a BB1 or not, I'll give you a quick rundown of my experiences. Firstly, I have had a B2 for nearly 4 years and it is a great unit. I do a lot of travelling by car and by plane and last year I was looking at ways of making the B2 portable. Then the BB1 was announced which I reckoned would be the answer to my requirements.
I pre-ordered the BB1 in August 2019 and received it in late September. To say that I was impressed with it is a massive understatement. I love it!!
Over the last few months I have purchased some additional items which make it even better! Those items are:
1. A DAC to 3.5mm converter to enable the use of headphones, earbuds, bluetooth airline connections etc. 20UKP
2. A dual pack of 8000mAh Lithium rechargeable batteries which I can velcro to the back of the BB1. These give 24 hours play each (one is use while the other is charging) 24USD
3. A carry pouch which hold the BB1, various cables, earbuds and the battery pack above. 25USD
4. 8 x AA 3000mAh Lithium rechargeable batteries and matching charger. 50USD
5. A 512GB microSD card. 85USD
I also have a set of over-ear bluetooth headphones.
The AA Lithium rechargeables are particularly good, with each set lasting for 9.5 hours and recharge in 3 hours.
I took the BB1 on a transatlantic flight to USA in November 2019 and it really helped with the comfort of the journey. I preloaded all of my music, a number of favourite radio programmes and a set of audio books. The 9.5 hour flight passed so quickly I was amazed! It seemed like 2 or 3 hours!! Also, with bluetooth headphone I can get out of my seat, walk around, go to the loo and still listen to the BB1.
Then my wife and I drove non-stop from Atlanta, Georgia to Virginia Beach, Virginia (700 miles) to stay with friends and had the BB1 playing music in random mode all the way. Again, we had a great time. Discovering lots of forgotten music .... brilliant!
Another transatlantic flight back home with the BB1, again this passed by very quickly.
To summarise, for me I have now got the perfect device for long distance travels. Also I suffer from severe tinnitus following a bad skiing accident in 2001 (spent a while in an Austrian hospital getting a hip rebuilt) so I listen to the BB1 overnight with earbuds which helps distract me from the permanent riot of noises going on in my head.
I hope this helps you to decide!
Regard,
Peter.
