In-ear monitor with shaped dual bore

An in-ear monitor comprising:

• an in-ear monitor enclosure;
• means for receiving a signal from an external source;
• a first diaphragm driver disposed within said in-ear monitor enclosure and electrically coupled to said receiving means, said first diaphragm driver having a first acoustic output;
• a second diaphragm driver disposed within said in-ear monitor enclosure and electrically coupled to said receiving means, said second diaphragm driver having a second acoustic output, wherein said first and second acoustic outputs are acoustically combined to form a third acoustic output;
• an armature driver disposed within said in-ear monitor enclosure and electrically coupled to said receiving means, said armature driver having a fourth acoustic output;
• and
• a sound delivery member coupled to said in-ear monitor enclosure, wherein said sound delivery member has an integrated first sound delivery tube extending through the entire length of said sound delivery member and an integrated second sound delivery tube extending through the entire length of said sound delivery member, wherein said first and second sound delivery tubes are discrete within said sound delivery member, wherein said third acoustic output is acoustically coupled to an acoustic input of said first sound delivery tube and said fourth acoustic output is acoustically coupled to an acoustic input of said second sound delivery tube, and wherein said sound delivery member is configured to accept a removable sleeve.
