Colchester have signed ex-Wigan winger Sanmi Odelusi on a free transfer and added four players on loan, including midfielder Brandon Comley from QPR.
Odelusi, 24, has agreed a deal until the end of the season while Comley, 21, will stay with the U's until January.
Crystal Palace defender Ryan Inniss, 22, has signed on a season-long loan, with striker Brandon Hanlan, 20, joining from Charlton until January.
Forward Nicke Kabamba, 24, has signed on loan until January from Portsmouth.
Kabamba arrived at Fratton Park in January, after scoring 33 in 70 games for Hampton & Richmond.
Inniss played 10 times for Southend on loan last term, while Hanlan has played 16 times for the Addicks.
"I'm not a hold-up sort of forward, I like to run in behind and that seems to suit the way Colchester go about things," Odelusi told BBC Essex.
"I had some good experience in this division last year, helping Blackpool get promoted, so I know what it's all about."
