Will this work with my Bose or Sennheiser headphones?
Yes, if your headphones use a standard 3.5mm jack, this will adapt them to fit a 2.5mm port. Note that some noise-canceling headphones have specific wiring, but this standard TRRS layout works for most.
Is this for "Balanced" audio players?
Yes. Many high-end DAPs use a 2.5mm 4-pole jack for balanced output. This adaptor allows you to connect your 3.5mm headphones to those ports.
Can I use my phone headset for my office desk phone?
Many cordless and desk phones use a 2.5mm headset jack. This 4-pole adaptor allows you to use your modern 3.5mm smartphone headset (with mic) for those calls.
