I've always been happy with my Littmann.
Excited for you.
Take care of yourself!
I wouldn't use anything other than a Littman. The earpieces fit your ears very well and help block outside noises helping make lung, heart and abdominal noises nice and clear and loud. the cost may be higher but most definitely worth the price. The price also makes up for the aggravation you get when using lower quality stethoscopes that you can't hear anything out of and you find yourself making the room deathly quiet just to be able to maybe hear something. Lol! So....my vote is for Littman all the way.
Hope this was helpful.
I go with Littmann also....the sound quality is much better.
2 tins and a piece of string a nono then lol
