OK just want to add my 2c on the Jabra elite 65ts. i got them last week. been using it mainly for calls and only had time today to really sit down and do a critical listen/compare.
unfortunately, SQ is worse than my $28
soundPeats Bluetooth earbuds I've been using and hoping to replace. I've tried all the tips that came with the Jabra elite 65t and had a perfect seal from the largest silicon tip.
been an audiophile for so long its really easy to tell SQ apart, since the lower SQ headphone would always sound like its underwater when you do an A+B listening session. so clarity wise there is nothing you can do to make it better.
To my ear out of the box 65ts has a sloped sound signature with severely lacking bass and bright highs. now i haven't had experience with other TWE before and have limited experience with IEMs my previous pair was an ER4P and Bose QC20. The SQ coming out
of the 65ts is about as good or slightly better than the QC20 and that's not encouraging. after tweaking it with the EQ on the Jabra app and the 12band EQ on my poweramp app i was able to change the signature and made it somewhat bearable. without EQ 65t just isn't good enough
for me to keep and I need it to connect to my computer sometimes which would be a pain to change EQ every time. i'm not sure if its due to AptX codec of the soundPeats or the extra large drivers but the SQ difference is like ER4P vs QC20 or my K1000 vs harman kardon. Guess i'll wait for the Sennheiser.
TWE SQ just isn't there yet atm. i'm still coming to terms of how a $28 BT earbuds are able to beat out a $200 TWE earbuds (even though I know they probably cost $15 to make from the Shenzhen factories). i really tried to like the 65ts but SQ is a big let down.
Lastly, the connection, call quality is very solid with 65t and there is no lag what so ever when streaming youtube or watching a video.
