Nice looking cable:smile_phones: Do you have a link for where you purchaced it or is it handmade ? I want to upgrade the cable for my MJ2s

Hi Byron, you could try custom made earpads : https://vesperaudio.com/earpads just contact them via email to see what they can do for you :o2smile:

lol - they look like they fit perfect though - think I will have to buy some :o2smile:

How well do they fit ?

Waiting for mine to come - hopefully the trimmers will come tomorrow for me to finish modding the b4 :ksc75smile:

I seen this on ebay: https://www.ebay.co.uk/itm/DC-12-6V-1A-Battery-Rechargeable-Charger-EU-AU-UK-US-Plug-For-Li-ion-Battery/222559646129?hash=item33d196b1b1:m:mrzuh3AGNGuFKjsNJP-ey1A:rk:6:pf:0 postage is from Hong Kong though and you probably would have to swap the tip

Hi Mullle not sure if this will help https://www.head-fi.org/threads/sennheiser-hd-590-graph.62262/ Best regards

seems to be legit - I bought my b4 from their store (doukstore) about a month ago - I couldn't find this upgraded b4-x on Amazon or anywhere else for that matter so it's fairly new I suppose - I will order it next week and put a review up if/when it comes

Thanks for the links and advice ledzep I found an upgraded version of the b4 - https://www.ebay.co.uk/itm/Little-Bear-B4-X-Valve-Tube-Dual-Mono-Balanced-Portable-Headphone-Amplifier-HiFi/283236997632 might be of some interest...

Hi led, I have insulated my b4 with copper tape and changed the caps like you, I have noticed an improvement in sq and battery life and just wanted to ask where did you buy the trimmers ? would any good 3 pin trimmer do or are they based on voltage etc

Hi gojoe, I replaced the caps and insulated my little bear b4 with copper tape like a user on this site (ledzep) and can honestly say I have noticed sq improvements but like you I'm exploring portable/desktop amp/dacs aswell with the ability to swap out op-amps

Hi everyone. I'm Baddie Came across this site whilst researching op-amps for my asus xonar stx ii and got some Burson Audio v6 classics for it and a V5i for my Little bear b4. now looking to get some AKG K702's to rediscover my 50000+ digital music collection
