So these are the Sennheiser Accentum, they have impressive active noise canlceiton for a pair of entry level ANC headphones, they have a monster 50 hour battery life and they have a lot of resonance in their bass. But the Accentum’s do have their issues. But today we’re going to compare the Sennheiser Accentum to what I feel are their most direct competitors, the Sony WH-CH720N which have been my favorite headphones to recommend for the gym for the past few months.
